CLI Command Updates 1 This chapter reflects new and updated commands that are available for use with the Dell PowerVault MD 34XX/38XX Series storage arrays. NOTE: Not all commands are valid with all storage arrays. Some commands are specific to certain platforms. CAUTION: Script commands are capable of changing the configuration and may cause loss of data if not used correctly. Command operations are performed as soon as you run the commands.
About The Command Line Interface 2 This guide is intended for system administrators, developers, and engineers who need to use the command line interface (CLI) tool and its associated commands and script files. Selected CLI commands perform functions that can also be accessed from the Modular Disk (MD) Storage Manager, which is the graphical user interface (GUI) to the storage array.
How To Use The Command Line Interface Using the CLI commands, you can access the script engine, specify which storage array receives the script commands, and set operation environment parameters. A CLI command consists of the following elements: • The term SMcli • Storage array identifier • Parameters • Script commands The following syntax is the general form of a CLI command: SMcli storageArray parameters script-commands; where, SMcli invokes the command line interface.
• Set passwords • Add storage arrays • Specify communication parameters • Enter individual script configuration commands • Specify a file containing script configuration commands The following are general forms of the CLI commands, showing the parameters and terminals used in each command. The table below lists definitions for the parameters shown in the CLI commands. Table 1.
[-n storage-array-name | -w WWID | -h host-name | -r (host_sa | direct_sa)] [-S] SMcli -d [-w][-i][-s][-v][-S] SMcli -m host-name-or-IP-address -F email-address [-g contactInfoFile][-S] SMcli -A [host-name-or-IP-address [host-name-or-IP-address]] [-S] SMcli -X (-n storage-array-name | -w WWID | -h host-name) SMcli -? Command Line Parameters Table 2.
Parameter Definition -c Use to indicate that you are entering one or more script commands to run on the specified storage array. Terminate each command by using a semicolon (;). You cannot place more than one -c parameter on the same command line. You can include more than one script command after the -c parameter. -d Use to display the contents of the script configuration file. -e Use to disable syntax checking when executing the current CLI command.
Parameter Definition -h Use with the -a and -x parameters to specify the host name that is running the SNMP agent to which the storage array is connected. -I Use to specify the type of information to be included in the e-mail alert notifications. The following are valid information arguments: • • • eventOnly— Only event information is included in the e-mail. profile— Event and array profile information is included in the e-mail.
Parameter Definition • -q The storage array password is specified by using the -c parameter and the set session password=password command. Use to specify how frequently to include additional profile or support bundle information in the e-mail alert notifications. An e-mail alert notification that contains at least the basic event information is always generated for every critical event. If you set the-I parameter to eventOnly, the only valid argument for -q is everyEvent.
Parameter Definition -v Use with the -d parameter to display the current global status of the known devices in the storage array configuration file. (The configuration file lists all of the devices in a storage array configuration and the relationship between the devices. Use the configuration file to reconstruct a storage array). -X (uppercase) Use to delete a storage array from the configuration file.
• The CLI automatically saves the error data by writing the data to a file with a standard name. • The CLI does not have any provisions to avoid overwriting an existing version of the file containing error data.
Status Value Meaning 14 The RAID controller module was unable to communicate with the storage array. 15 A duplicate argument was entered. 16 An execution error occurred. 17 A host was not at the specified address. 18 The World Wide Identifier (WWID) was not in the configuration file. 19 The WWID was not at the address. 20 An unknown IP address was specified. 21 The event monitor configuration file was corrupted. 22 The storage array was unable to communicate with the event monitor.
Windows: SMcli -n "Payroll_Array" -c "set storageArray userLabel=\"Finance_Array\";" Linux: SMcli -n ‘Payroll_Array’ -c ‘set storageArray userLabel="Finance_Array";’ This example shows how to delete an existing virtual disk and create a new virtual disk on a storage array. The existing virtual disk name is Stocks_<_Bonds. The new virtual disk name is Finance. The RAID controller module host names are finance1 and finance2. The storage array is protected and requires the password TestArray.
About The Script Commands 3 You can use the script commands to configure and manage a storage array. The script commands are distinct from the command line interface (CLI) commands; however, you enter the script commands using the command line interface. You can enter individual script commands, or run a file of script commands. When entering an individual script command, include it as part of a CLI command. When running a file of script commands, include the file name as part of a CLI command.
Operation Activities Firmware management Downloading RAID controller module, enclosure management module (EMM), and physical disk firmware Script Command Structure All script commands have the following structure: command operand-data {statement-data} where, command identifies the action to be performed, operand-data represents the storage array component to configure or manage (such as a RAID controller module, physical disk, or disk group), and statement-data is what you want to do to the component (s
Object Type Identifier host User label hostChannel Host channel identifier hostGroup User label hostPort User label snapVirtualDiskName Virtual disk user label snapshot Virtual disk user label snapGroup A snapshot group contains a sequence of snapshot images of an associated base virtual disk. A snapshot group has a repository virtual disk that is used to save data for all of the snapshot images that are part of the snapshot group.
Command Syntax Description check object {statement‑data} Starts a synchronous operation to report on errors in the object. clear object {statement‑data} Discards the contents of some attribute of an object. This is a destructive operation that cannot be reversed. create object {statement‑data} Creates an object of the specified type. deactivate object {statement‑data} Removes the environment for an operation. delete object Deletes a previously created object.
Command Syntax Description stop object {statement‑data} Stops an asynchronous operation. suspend object {statement‑data} Suspends an operation. You can then restart the suspended operation, and it continues from the point at which it was suspended. Recurring Syntax Elements Recurring syntax elements are a general category of variables and parameters you can use in one or more script commands.
Recurring Syntax Syntax Value physical disk-channel-identifier-list physical disk-channel-identifier {physical diskchannel-identifier} host-channel-identifier (01 | 02 | 11 | 12) physical disk-type (Serial Attached SCSI [SAS]) feature-identifier (snapshot | virtualDiskCopy) repository-spec instance-based-repository-spec | count-basedrepository-spec ethernet-port-options IPV4Address=ipv4-address| IPV4ConfigurationMethod=[(static | dhcp)] | IPV4GatewayIP=ipv4-address| IPV4SubnetMask=ipv4-address|
Recurring Syntax Syntax Value IPV4SubnetMask=ipv4-address | IPV4VlanID=integer | IPV6VlanID=integer | maxFramePayload=integer | tcpListeningPort=tcp-port-id| NOTE: You must set the enableIPV4 parameter or the enableIPV6 parameter to TRUE to ensure that the specific IPV4 or IPV6 setting is applied. NOTE: The IPV6 address space is 128 bits. It is represented by eight 16-bit hexadecimal blocks separated by colons. You may drop leading zeros, and use a double colon to represent consecutive blocks of zeroes.
Recurring Syntax Syntax Value [physicalDiskType=physical disk-type] [enclosureLossProtect=boolean] WWID string-literal For hostPort identifiers this is a 16-digit hex number without any colon delimiters. nvsram-offset hexadecimal-literal host-type string-literal | integer-literal nvsram-byte-setting nvsram-value (0x hexadecimal | integer-literal) nvsram-bit-setting nvsram-mask, nvsram-value (0x hexadecimal, 0x hexadecimal | integer-literal) ipv4-address (0–255).(0–255).(0–255).
Recurring Syntax Syntax Value NOTE: The virtualDisksPerGroupCount parameter is the number of equal capacity virtual disks per disk group.
For enclosure loss protection to work, your configuration must adhere to the following guidelines: Table 9. CLI and Script Commands for Version 11.25 Level Criteria for Enclosure Loss Protection Minimum Number of Enclosures Required Disk Pool The disk pool contains no more 6 than two physical disks in a single enclosure. RAID Level 6 The virtual disk group contains no more than two physical disks in a single enclosure.
drawerLossProtect parameter are not set to the same value, the storage array returns an error message and a storage array configuration will not be created. To determine if a free capacity area exists, run the show diskGroup command. The default physical disk is SAS. The physicalDiskType parameter is not required if only one type of physical disks is in the storage array. If you use the physicalDiskType parameter, you also must use the hotSpareCount parameter and the virtualDiskGroupWidth parameter.
NOTE: When all the required hardware and the I/O interface is DA-capable, you can set the dataAssurance parameter to enabled and then use DA with certain operations. For example, you can create a virtual disk group that includes DA-capable physical disks, and then create a virtual disk within that disk group that is DA-enabled. Other operations that use a DA-enabled disk have options to support the DA feature.
Configuring A Storage Array 4 This chapter explains how to run script commands from the command line to create a virtual disk from a group of physical disks, and how to configure a redundant array of independent disks (RAID) storage array. This chapter assumes that you understand basic RAID concepts and terminology. Before configuring the storage array, become familiar with the concepts of physical disks, disk groups, virtual disks, host groups, hosts, and RAID controller modules.
access data is affected by the disk group RAID level and the segment size settings. Data protection is determined by the RAID level, hardware redundancy (such as global hot spares), and software redundancy (such as the Snapshot feature).
save the output to a file. To save the output to a file, enter the command as shown in the following example: client>smcli 123.45.67.89 -c "show storageArray profile;" -o c:\folder\storageArrayprofile.txt In this example, the name folder is the folder in which you choose to place the profile file, and storageArrayprofile.txt is the name of the file. You can choose any folder and any file name.
Saving A Configuration To A File CAUTION: When you write information to a file, the script engine does not check to determine if the file name already exists. If you choose the name of a file that already exists, the script engine writes over the information in the file without warning. After you have created a new configuration or if you want to copy an existing configuration for use on other storage arrays, you can save the configuration to a file.
The userLabel parameter is the name to give to the virtual disk. The virtual disk name can be any combination of alphanumeric characters, hyphens, and underscores. The maximum length of the virtual disk name is 30 characters. Spaces are not allowed. You must put quotation marks (" ") around the virtual disk name. The physicalDisks parameter is a list of the physical disks that you want to use for the disk group. Enter the enclosure ID and slot ID of each physical disk that you want to use.
(SAS)] [capacity=virtualDiskCapacity | owner=(0 | 1) | segmentSize=segmentSizeValue] [enclosureLossProtect=(TRUE | FALSE)]) NOTE: The physicalDiskType, capacity, owner, segmentSize, and enclosureLossProtect parameters are optional. You can use one or all of the optional parameters as needed to help define your configuration. You do not, however, need to use any optional parameters. This command is similar to the previous create virtualDisk command, which allows the user to assign the physical disks.
Enclosure Loss Protection The enclosureLossProtect parameter is a boolean switch that turns enclosure loss protection on or off. To work properly, each physical disk in a virtual disk group must be in a separate enclosure. Enclosure loss protection is set under the following conditions: • • You assign the physical disks. The RAID controller module assigns the physical disks. The following table shows possible results for the enclosureLossProtect parameter.
command. If you are satisfied with the parameter values that the show storageArray autoConfiguration command returns, run the autoConfigure storageArray command without new parameter values.
Example Of The Auto Configuration Command client>smcli 123.45.67.89 -c "autoConfigure storageArray physicalDiskType=SAS raidLevel=5 diskGroupWidth=8 diskGroupCount=3 virtualDisksPerGroupCount=4 hotSpareCount=2 segmentSize=8;" The command in this example creates a storage array configuration that uses SAS physical disks set to RAID level 5. Three disk groups are created. Each disk group consists of eight physical disks configured into four virtual disks.
characters. You must put quotation marks (" ") around the password. The following example shows how to use the set storageArray command to define a password: client>smcli 123.45.67.89 -c "set storageArray password=\"1a2b3c4d5e"\;" Setting Up SMTP And SNMP Alerts The storage array can be set up to send automatic e-mail alert messages to specified email addresses when specific events occur.
array. The only time you might need to use this parameter is if you need to change how the storage array behaves relative to the hosts. Before you can define the default host type, you need to determine what host types are connected to the storage array. To return information about host types connected to the storage array, you can use the show storageArray command with the defaultHostType parameter or hostTypeTable parameter.
Assigning Global Hot Spares Hot spare physical disks can replace any failed physical disk in the storage array. The hot spare must be the same type of physical disk as the physical disk that failed and must have capacity greater than or equal to any physical disk that can fail. If a hot spare is smaller than a failed physical disk, the hot spare cannot be used to rebuild the data from the failed physical disk. Hot spares are available only for RAID levels 1 or 5.
You can configure the MD storage management software to notify only the event levels that you specify. For example, you can configure alert notifications only for Critical and Warning events. 1. Open the Configure Alerts dialog by performing one of these actions: a. Select a storage array in the Devices tab in the EMW. b. Select Edit → Configure Alerts. The Configure Alerts dialog is displayed. Go to step 3. c. Select Configure Alerts in the Setup tab in the EMW. Go to step 2. 2.
Using The Snapshot Feature 5 The following types of virtual disk snapshot premium features are supported on the MD storage array: • • Snapshot Virtual Disks using multiple point-in-time (PiT) groups Snapshot Virtual Disks (Legacy) using a separate repository for each snapshot NOTE: This section describes the Snapshot Virtual Disk using PiT groups. If you are using the Snapshot Virtual Disk (Legacy) premium feature, see Using The Snapshot (Legacy) Feature.
Only the following can be included in a snapshot image: • Standard virtual disks • Thin provisioned virtual disks • Consistency groups Snapshot Groups And Snapshot Consistency Groups The Snapshot Virtual Disk premium feature supports two types of snapshot groups: • Snapshot groups • Consistency groups Snapshot Groups The purpose of a snapshot group is to create a sequence of snapshot images on a given base virtual disk without impacting performance.
• Consistency groups can be created initially with or without member virtual disks. • Snapshot images can be created for a consistency group to enable consistent snapshot images between all member virtual disks. • Consistency groups can be rolled back. • A virtual disk can belong to multiple consistency groups. • Only standard virtual disks and thin virtual disks can be included in a consistency group.
Creating Snapshot Images Guidelines before creating a snapshot image: • If you attempt to create a snapshot image on a snapshot group and that snapshot group has reached its maximum number of snapshot images. The failBaseWrites or purgeSnapImages parameters used with the create snapGroup command allows you to choose to either fail the write attempt or automatically purge a specified number of older snapshot images.
retainCount=numberOfSnapImages | ignoreSnapVirtualDisk=(TRUE | FALSE) | snapImageID=OLDEST) Creating A Consistency Group Snapshot Virtual Disk Creating a snapshot virtual disk of a consistency group creates a viewable virtual disk of specific images in the consistency group. A consistency group snapshot virtual disk can be made up of a single base virtual disk or multiple base virtual disks from the consistency group.
Create a consistency group snapshot virtual disk that has a repository full limit set to 60 percent on a snapshot consistency group named snapCG1 with these three members cgm1, cgm2, and cgm3, with the following command: create cgSnapVirtualDisk userLabel="cgSnapVirtualDisk3" cgSnapImageID="snapCG1:oldest" repositoryFullLimit=60; Create a read/write consistency group snapshot virtual disk with automatic repository selection on a snapshot consistency group named snapCG1 with members cgm1, cgm2, and cgm3, wit
• The repository’s reserve space for reuse within the consistency group is released. • Any member virtual disk associated with the deleted snapshot image(s) is moved to a Stopped state. • The member snapshot virtual disks associated with the deleted snapshot image(s) is deleted.
To start a rollback for a snapshot group named snapGroup1: start snapImage ["snapGroup1"] rollback You can specify a snapshot image rollback for a specific snapshot image in a snapshot group named 12345: stop snapImage ["snapGroup1:12345"] rollback; To stop a rollback operation for the most recent snapshot image in a snapshot group that has the name snapGroup1: stop snapImage ["snapGroup1:newest"] rollback; The repository virtual disk associated with the snapshot image continues to track any new changes bet
Deleting A Snapshot Group CAUTION: All of the data in the snapshot group is lost as soon as you run this command. This command deletes an entire snapshot group and, if specified, the associated repository virtual disks. delete snapGroup ["snapGroupName"] deleteRepositoryMembers=TRUE; In the example, the repository virtual disks were preserved . By default, all member virtual disks in the repository virtual disk are retained as unused, unmapped standard virtual disks.
Deleting A Consistency Group This command deletes a snapshot consistency group. You can either delete both the consistency group and the repository virtual disks contained by the consistency group, or you can delete only the consistency group and leave the repository virtual disks contained in the consistency group intact.
autoDeleteLimit allows you to configure each snapshot group to perform automatic deletion of its snapshot images to keep the total number of snapshot images in the snapshot group at or below a maximum number of images. When the number of snapshot images in the snapshot group is at the maximum limit, the autoDeleteLimit parameter automatically deletes snapshot images whenever a new snapshot image is created in the snapshot group.
The removeCGMemberVirtualDisk parameter is the name of the member virtual disk that you want to remove; deleteRepositoryMembers determines whether the command removes all the repository members from the consistency group.
preReadConsistencyCheck=(TRUE | FALSE) readCacheEnabled=(TRUE | FALSE) writeCacheEnabled=(TRUE | FALSE) cacheReadPrefetch=(TRUE | FALSE) Syntax Applicable To Only One Virtual Disk set (virtualDisk ["virtualDiskName"] | virtualDisk ) addCapacity=virtualDiskCapacity [addPhysicalDisks=(enclosureID1,drawerID1,slotID1 ...
• Capacity for rollback processing, which is 1/5000th of the capacity of the base virtual disk. If you are creating a new repository virtual disk when you run this command, you must enter the name of a disk group or disk pool from which you want the repository virtual disk. Optionally, you can also define the capacity of the repository virtual disk. The following capacity values are supported: • • • A percentage ( integer value) representing an amount of the base virtual disk capacity.
• standalone snapshot virtual disk • snapshot virtual disk that is a member of a consistency group If the snapshot virtual disk is not in a Failed state, the firmware displays an error message and does not run this command. revive snapVirtualDisk ["snapVirtualDiskName"] NOTE: This command for a snapshot virtual disk used in online virtual disk copy.
Using The Snapshot (Legacy) Feature 6 The following types of virtual disk snapshot premium features are supported on the MD storage array: • Snapshot Virtual Disks using multiple point-in-time (PiT) groups • Snapshot Virtual Disks (Legacy) using a separate repository for each snapshot NOTE: This section describes the Snapshot Virtual Disk (legacy) premium feature. If you are using the Snapshot Virtual Disk using PiT groups, see the Using The Snapshot Feature section.
The following table lists the components that comprise a snapshot virtual disk and briefly describes what they do. Table 11.
• You must satisfy the requirements of your host operating system for creating snapshot virtual disks. Failure to meet the requirements of your host operating system results in an inaccurate point-in-time image of the source virtual disk or the target virtual disk in a virtual disk copy.
Preparing Host Servers To Create An Initial Snapshot Virtual Disk CAUTION: Before you create a new point-in-time image of a source virtual disk, stop any data access (I/O) activity or suspend data transfer to the source virtual disk to ensure that you capture an accurate point-in-time image of the source virtual disk. Close all applications, including Windows Internet Explorer, to make sure all I/O activity has stopped.
NOTE: Use one or all of the optional parameters as needed to help define your configuration. You do not need to use any optional parameters. See step 1 through step 4 in the preceding section, Preparing Host Servers To Create An Initial Snapshot Virtual Disk. The following example shows a command in which users assign the physical disks: client>smcli 123.45.67.89 -c "create snapshotVirtualDisk sourceVirtualDisk= \"Mars_Spirit_4\" repositoryRAIDLevel=5 repositoryPhysicalDisks=(1,1 1,2 1,3 1,4 1,5);" The comm
NOTE: Use one or all of the optional parameters as needed to define your configuration. It is not necessary to use any optional parameters. The following example is a command in which software assigns the physical disks: client>smcli 123.45.67.89 -c "create snapshotVirtualDisk sourceVirtualDisk= \"Mars_Spirit_4\" repositoryDiskGroup=2 freeCapacityArea=2;" The command in this example creates a new snapshot repository virtual disk in disk group 2. The source virtual disk is Mars_Spirit_4.
The following example is the script file version of the command: create snapshotVirtualDisk sourceVirtualDisk= "Mars_Spirit_4" repositoryRAIDLevel=5 repositoryPhysicalDiskCount=3; User-Defined Parameters Parameters for the create snapshotVirtualDisk command enable you to define the snapshot virtual disk to suit the requirements of your storage array. The following table lists the parameters and descriptions of Snapshot Virtual Disk. Table 13.
Parameter Description warningThresholdPercent Specifies how full to allow the snapshot repository virtual disk to get before sending a warning that the snapshot repository virtual disk is close to capacity. The warning value is a percentage of the total capacity of the snapshot repository virtual disk. The default value is 50, which represents 50 percent of total capacity. (Change this value using the set snapshotVirtualDisk command.
The following example is the script file version of the command: create snapshotVirtualDisk sourceVirtualDisk= "Mars_Spirit_4" repositoryRAIDLevel=5 repositoryPhysicalDiskCount=5 physicalDiskType= SAS userLabel="Mars_Spirit_4_snap1" repositoryUserLabel="Mars_Spirit_4_rep1" warningThresholdPercent=75 repositoryPercentOfSource=40 repositoryFullPolicy=failSnapShot; NOTE: In the previous examples, the names for the snapshot virtual disk and repository virtual disk are defined by the user.
The following example shows the command to change the name of a snapshot virtual disk: client>smcli 123.45.67.89 -c "set virtualDisk [\"Mars_Spirit_4-1\"] userLabel=\"Mars_Odyssey_3-2\";" The following example is the script file version of the command: set virtualDisk ["Mars_Spirit_4-1"] userLabel= "Mars_Odyssey_3-2"; When you change the warning threshold percent and repository full policy, you can apply the changes to one or several snapshot virtual disks.
Preparing Host Servers To Re-create A Snapshot Virtual Disk CAUTION: Before you create a new point-in-time image of a source virtual disk, stop any data access (I/O) activity or suspend data transfer to the source virtual disk and snapshot virtual disk to ensure that you capture an accurate point-in-time image of the source virtual disk. Close all applications, including Windows Internet Explorer, to make sure all I/O activity has stopped.
Using The Virtual Disk Copy Feature 7 This chapter describes how the Virtual Disk Copy feature works, lists the script commands for Virtual Disk Copy, and explains how to use the commands to create and run Virtual Disk Copy. Additional information about Virtual Disk Copy and related definitions is available in the Deployment Guide and the Administrator's Guide.
In either type of virtual disk copy, the target virtual disk is locked and cannot be accessed while the copy operation is in place. After completion of the virtual disk copy of a snapshot (legacy), the legacy snapshot is disabled. After completion of the virtual disk copy using a snapshot image, the snapshot image is deleted and the snapshot virtual disk is disabled. NOTE: You can have a maximum of eight virtual disk copies in progress at one time.
Creating A Virtual Disk Copy Before creating a virtual disk copy, ensure that a suitable target virtual disk exists on the storage array, or create a new target virtual disk specifically for the virtual disk copy. The target virtual disk must have a capacity equal to or greater than the source virtual disk. You can have a maximum of eight virtual disk copies in progress at one time.
Preparing Host Servers To Create A Virtual Disk Copy CAUTION: Before you create a new copy of a source virtual disk, stop any data access (I/O) activity or suspend data transfer to the source virtual disk (and, if applicable, the target disk) to ensure that you capture an accurate point-in-time image of the source virtual disk. Close all applications, including Windows Internet Explorer, to make sure all I/O activity has stopped.
– In Linux, mount the virtual disk. See step 1 to step 4 in Preparing Host Servers To Create A Virtual Disk Copy. The create virtualDiskCopy command might look like the following example: client>smcli 123.45.67.89 -c "create virtualDiskcopy source=\"Jaba_Hut\" target= \"Obi_1\" copyPriority=medium targetreadonlyenabled=true" The command in this example copies the data from the source virtual disk named Jaba_Hut to the target virtual disk named Obi_1.
The following example shows a command that returns information about a virtual disk used for a virtual disk copy: client>smcli 123.45.67.89 -c "show virtualDiskCopy source [\"Jaba_Hut\"];" The command in the preceding example requests information about the source virtual disk Jaba_Hut. If you want information about all virtual disks, use the allVirtualDisks parameter. You can also request information about a specific target virtual disk.
The following example shows how to change parameters using the set virtualDiskCopy command: client>smcli 123.45.67.89 -c "set virtualDiskcopy target [\"Obi_1\"] copyPriority=highest targetreadonlyenabled=false;" The following example is the script file version of the command: set virtualDiskcopy target ["Obi_1"] copyPriority= highest targetreadonlyenabled=false; Recopying A Virtual Disk CAUTION: The recopy virtualDiskCopy command overwrites existing data on the target virtual disk and makes the target virt
NOTE: If your operating system requires additional instructions, you can find those instructions in your operating system documentation. After your server has been prepared, see Recopying The Virtual Disk to recopy the virtual disk. Recopying The Virtual Disk After first preparing the host server(s) as specified in the preceding procedure, use the following examples to make a virtual disk copy.
Removing Copy Pairs The remove virtualDiskCopy command enables you to remove a virtual disk copy pair from the storage array configuration. All virtual disk copy information for the source virtual disk and target virtual disk is removed from the storage array configuration. The data on the source virtual disk or target virtual disk is not deleted. Removing a virtual disk copy from the storage array configuration also removes the read-only attribute for the target virtual disk.
Using The Remote Replication Premium Feature 8 The following types of Remote Replication premium features are supported on the MD storage array: Remote Replication Standard asynchronous replication using point-in-time images to batch the resynchronization between the local and remote site. This type of replication is supported on either Fibre Channel or iSCSI storage arrays (both local and remote arrays must have the same data protocol).
primary (local) and secondary (remote) virtual disk pairs, called replicated pairs, write operations to the primary virtual disk of the pair are tracked by the RAID controller firmware and captured in a point-intime image and transferred to the secondary virtual disk in the pair. Remote Replication groups allow you to manage synchronization of both virtual disks to create a consistent data set across local and remote storage arrays.
In this case, the remote write operation cannot be completed to the secondary virtual disk, and the primary virtual disk and the secondary virtual disk are no longer correctly replicated. The primary RAID controller module transitions the replicated pair into an Unsynchronized state and sends an I/O completion to the primary host. The primary host can continue to write to the primary virtual disk, but remote writes do not take place.
Remote Replication Group After your Remote Replication premium feature is activated on both local and remote storage arrays, you must create Remote Replication groups on the local storage array. A replication group contains at least one replicated virtual disk pair, one on the local storage and one on the remote storage array, that share data synchronization settings. Multiple replicated pairs can reside in a replication group, but each pair can only be a member of one Remote Replication group.
– The first port that successfully establishes an iSCSI connection is used for all subsequent communication with that remote storage array. If that connection subsequently fails, a new session is attempted using any available ports. Primary And Secondary Virtual Disks Before you create any replication relationships, virtual disks must exist at both the primary site and the secondary site. The virtual disk that resides on the local storage array is the primary virtual disk.
The create asyncRemoteReplicationGroup command creates a new, empty remote replication group on both the local storage array and the remote storage array. Each replicated pair you add to the remote replication group share the same synchronization settings, primary and secondary role, and write mode. This command must be run on the local storage array.
• warningThresholdPercent The following parameters allow you to change (or force) the primary/secondary role of a replication group, or whether or not to perform a synchronization before changing primary/secondary roles. • role • force • nosync You can apply the changes to one or several remote replicated pairs by using this command. Use the primary virtual disk name to identify the remote replicated pairs for which you are changing the properties.
reduce any performance impact to the host application that might occur while any changed data on the primary virtual disk is copied to the secondary virtual disk. When a replication relationship is in a suspended state, the primary virtual disk does not make any attempt to contact the secondary virtual disk. Any writes to the primary virtual disk are persistently logged in the replication repository virtual disks.
Disabling The Remote Replication Premium Feature You disable the Remote Replication premium feature to prevent the new replication relationship from being created. When you disable the Remote Replication premium feature, the premium feature is in a Disabled/Active state. In this state, you can maintain and manage previously existing replication relationships; however, you cannot create new relationships.
Command Description remove asyncRemoteReplicationGroup incompleteRemoteReplication Removes an orphaned replicated pair virtual disk. reset storageArray arvmStats reset storageArray iscsiIpAddress Resets IP address for the remote storage array to re-establish connection with the local storage array or resets synchronization statistics for member virtual disks to relative 0.
Using The Remote Replication (Legacy) Premium Feature 9 The Remote Replication (legacy) premium feature provides for online, real-time replication of data between storage arrays over a remote distance. In the event of a disaster or a catastrophic failure on one storage array, you can promote the second storage array to take over responsibility for computing services.
The RAID controller module owner of the primary virtual disk initiates remote writes to the secondary virtual disk to keep the data on the two virtual disks synchronized. The secondary virtual disk maintains a replication (or copy) of the data on its associated primary virtual disk. The RAID controller module owner of the secondary virtual disk receives remote writes from the RAID controller module owner of the primary virtual disk but will not accept host write requests.
Data Replication The RAID controller modules manage data replication between the primary virtual disk and the secondary virtual disk. This process is transparent to host machines and applications. This section describes how data is replicated between the storage arrays that are participating in Remote Replication (legacy). This section also describes the actions taken by the RAID controller module owner of the primary virtual disk if a link interruption occurs between storage arrays.
If one replication relationship in the group becomes unsynchronized, all of the replication relationships in the group become unsynchronized. Any write activity to the remote, secondary storage arrays is prevented to protect the consistency of the remote data set.
blocks of data that have changed on the primary virtual disk during the link interruption are copied to the secondary virtual disk. CAUTION: Possible loss of data access – Any communication disruptions between the primary storage array and the secondary storage array while resynchronization is underway could result in a mix of new data and old data on the secondary virtual disk. This condition would render the data unusable in a disaster recovery situation.
Enabling The Remote Replication (Legacy) Premium Feature The first step in creating a remote replication is to make sure that the Remote Replication (legacy) premium feature is enabled on both storage arrays. Because Remote Replication (legacy) is a premium feature, you need a feature key file to enable the premium feature.
• You define the number of physical disks, but not specific physical disks, for the replication repository virtual disk. Activating The Remote Replication (Legacy) Premium Feature With User-Assigned Physical Disks Activating the Remote Replication (legacy) premium feature by assigning the physical disks provides flexibility in defining your configuration by letting you choose from the available physical disks in your storage array.
The command in this example creates a new replication repository virtual disk in disk group 2 using the second free capacity area.
World Wide Identifier (WWID) of the storage array on which the secondary virtual disk resides. The primary virtual disk name, the secondary virtual disk name, and the remote storage array name (or WWID) are the minimum information that you need to provide. Using this command, you can also define synchronization priority, write order, and write mode.
• The synchronization priority • The write order • The write mode You can apply the changes to one or several remote replicated pairs by using this command. Use the primary virtual disk name to identify the remote replicated pairs for which you are changing the properties. This example shows how to use the set remoteReplication command: c:\...\smX\client>smcli 123.45.67.88 123.45.67.
This example shows how to use the command in a script file: suspend remoteReplication virtualDisk Jan_04_Account writeConsistency=false; The replication relationship remains suspended until you use the resume remoteReplication command to restart synchronization activities. This command restarts data transfers between a primary virtual disk and a secondary virtual disk in a replication relationship after the replication has been suspended or unsynchronized.
CAUTION: Possible loss of data access – Deleting a primary virtual disk or a secondary virtual disk permanently removes the data from the storage array. Disabling The Remote Replication (Legacy) Premium Feature You disable the Remote Replication (legacy) premium feature to prevent the new replication relationship from being created. When you disable the Remote Replication (legacy) premium feature, the premium feature is in a Disabled/Active state.
was created. Snapshot repository virtual disks cannot be selected as a source virtual disk or target virtual disk in a virtual disk copy. The virtual disk for which the point-in-time image is created is the source virtual disk and must be a standard virtual disk in the storage array. You can select snapshot virtual disks as the source virtual disk for a virtual disk copy.
Virtual Disk Expansion A Virtual Disk Expansion (VDE) is a modification operation that increases the capacity of a standard virtual disk or a snapshot repository virtual disk. The increase in capacity is achieved by using the free capacity that is available in the disk group of the standard virtual disk or the snapshot repository virtual disk.
Maintaining A Storage Array 10 Maintenance covers a broad spectrum of activities. Its goal is to keep a storage array operational and available to all hosts. This chapter provides descriptions of command line interface (CLI) and script commands that you can use to perform storage array maintenance.
Reconstructed media error The physical disk could not read the requested data on its first attempt or on any subsequent retries. The data is reconstructed from the redundant copy, rewritten to the drive, verified, and the error is reported to the MEL. Recovered media error The physical disk could not read the requested data on its first attempt. The result of this action is that the data is rewritten to the physical disk and verified. The error is reported to the MEL.
RAID 1 virtual disks The data is compared between the replicated physical disks, and data inconsistencies are repaired. RAID 0 virtual disks No redundancy exists. NOTE: Do not run consistency checking commands on RAID 0 virtual disks. Before attempting a consistency check, you must enable consistency checking using the set virtualDisk command.
Removing Persistent Reservations Persistent reservations preserve virtual disk registrations and prevent hosts, other than the host defined for the virtual disk, from accessing the virtual disk. You must remove persistent reservations before you perform the following changes to your configuration: • Change or delete logical unit number (LUN) mappings on a virtual disk holding a reservation. • Delete virtual disk groups or virtual disks that have any reservations.
Type of Information Description Virtual Disk A list of the virtual disk names.
values for the segment size. Using a single physical disk for a single request leaves other disks available to simultaneously service other requests. If the virtual disk is in a single-user large I/O environment, performance is maximized when a single I/O request is serviced with a single data stripe; use smaller values for the segment size.
For a consistency group snapshot virtual disk: set cgSnapVirtualDisk ["cgSnapshotVirtualDisk"] ssdCacheEnabled=TRUE When you turn off SSD caching for a virtual disk, cache contents is purged. You can turn on SSD caching for only one virtual disk per command. Creating SSD Cache To create ssdCache command SSD read cache: create ssdCache userLabel="ssdCacheName" physicalDisks=(enclosureID1,drawerID1,slotID1 ...
The modeling process runs in the background until you run the stop command. The file parameter is optional. If used, it will write modeling results to the file you specify. stop ssdCache [ssdCacheName] performanceModeling file="filename" Output is displayed directly on your screen, unless the file parameter is used. You can also access modeling results using MD Storage Manager.
physical disk-side channel out onto the loop and back again. Enough data is transferred to determine error conditions on the channel. If the test fails on any channel, this status is saved so that it can be returned if all other tests pass. The write test initiates a write command as it would be sent over an I/O data path to the diagnostics region on a specified physical disk. This diagnostics region is then read and compared to a specific data pattern.
If you take a RAID controller module offline, the second RAID controller module in the pair takes over. Disk groups and their associated virtual disks that were assigned to the offline RAID controller module are automatically reassigned to the remaining RAID controller module. CAUTION: Place a RAID controller module in Service mode only under the direction of Technical Support. Use Service mode when you want to perform an operation, such as replacing a RAID controller module.
Reconstructing A Physical Disk If two or more physical disks in a disk group have failed, the virtual disk shows a status of Failed. All of the virtual disks in the disk group are no longer operating. To return the disk group to an Optimal status, you must replace the failed physical disks. After replacing the physical disks, reconstruct the data on physical disks. The reconstructed data is the data as it would appear on the failed physical disks.
Script Commands 11 CAUTION: Script commands are capable of changing the configuration and may cause loss of data if not used correctly. Command operations are performed as soon as you run the commands. Before using the script commands, ensure that you have backed up all data, and have saved the current configuration so that you can reinstall it if the changes do not work. This chapter describes the script commands used to configure, monitor, and maintain a storage array.
• The script commands are not case sensitive. Type the commands in lowercase, uppercase, or mixed case. (In the following command descriptions, mixed case is used as an aid to reading the command names and understanding the purpose of the command.) • You must enter spaces in the commands as they are shown in the command descriptions.
NOTE: You can use any combination of alphanumeric characters, hyphens, and underscores for the names. Command names can have a maximum of 30 characters. If you exceed the maximum character limit, replace square brackets ([ ]) with angle brackets (< >) to overcome this limitation. On Microsoft Windows, you must put a backslash (\) before and after the name in addition to other delimiters. For example, the following name is used in a command running under a Windows operating system: [\"Engineering"\] For Linu

Before entering the autoConfigure storageArray command, run the show storageArray autoConfiguration command. The show storageArray autoConfiguration command returns configuration information in the form of a list of valid physical disk types, RAID levels, virtual disk information, and hot spare information.
Parameter Description virtualDisksPerGroupCount Number of equal-capacity virtual disks per disk group. Use integer values. hotSpareCount Number of hot spares in the storage array. Use integer values. For information about hot spares, see Assigning Global Hot Spares. segmentSize Amount of data (in kilobytes) that the RAID controller module writes on a single physical disk in a virtual disk before writing data on the next physical disk. Valid values are 8, 16, 32, 64, 128, 256, or 512.
Parameter Description secure drives to use. The values you can use are fips and sed. NOTE: The controller firmware does not support a mix of SED and FIPS drives within disk groups or disk pools. Example command autoConfigure storageArray securityType=capable securePhysicalDisks=fips; dataAssurance The setting to specify that a disk group, and the virtual disks within the disk group, has data assurance protection to make sure that the data maintains its integrity.
Parameters Table 17. Parameter Description drive The location of the drive that you want to use for a hot spare. For dense expansion enclosures, specify the enclosure ID value, the drawer ID value, and the slot ID value for the drive. For non-dense expansion enclosures, specify the enclosure ID value and the slot ID value for the drive. Enclosure ID values are 0 to 99. Drawer ID values are 0 to 4 . Slot ID values are 0 to 59.
Blink SSD Cache Description The start locate command identifies the Solid State Disks (SSDs) that are being used in the SSD cache by turning on the indicator lights for the SSDs. The stop locate command turns off the indicator lights on the SSDs.
Change SSD Cache Application Type Description This command changes the application type associated with the SSD cache. The application type can be web server, database, or multimedia. Changing the application type changes the block size, sub block size, populate on read threshold, and populate on write threshold for the virtual disks underlying the SSD cache.
Parameter Description primary virtual disk or the secondary virtual disk of a remote replication pair. Enclose the virtual disk name in square brackets ([ ]). If the virtual disk name has special characters, you also must enclose the virtual disk name in double quotation marks (" "). timeout The time interval within which the software can return the remote replication virtual disk status. The timeout value is in minutes.
Check Repository Consistency Description This command applies to a number of objects that have underlying repository virtual disks. The command produces a report based on analysis of the data in the repository.
Parameter Description \logs \repoConsistency.txt". This parameter must appear last, after any of the optional parameters. Check Storage Array Connectivity Description This command verifies that the local storage array and the remote storage array have a communication path and displays the connection details between the local and remote storage array. Before creating a remote replication group, you should check whether the local storage array and the remote storage array can communicate with each other.
Channel is checked. If the local storage array does not support iSCSI or Fibre Channel, an error message is displayed and the operation aborted. Check Virtual Disk Consistency Description This command checks a virtual disk for consistency and media errors, and writes the results of the check to a file.
NOTE: The starting logical block address and the ending logical block address are useful for very large single-virtual disk LUNs. Running a virtual disk consistency check on a very large single-virtual disk LUN can take a long time. By defining the beginning address and ending address of the data blocks, you can reduce the time that a virtual disk consistency check takes to complete. For a large virtual disk, you can set the priority to high without affecting the I/O.
Parameters Parameter Description all Use this parameter if you want to clear all remote replication faults from all remote replication groups and on all remote replication group member virtual disks. asyncRemoteReplicationGroup The name of the remote replication group from which you want to clear the remote replication fault. Enclose the remote replication group name in square brackets ([ ]).
Clear Storage Array Configuration Description Use this command to: • Clear the entire storage array configuration, and return it back to the initial installation state. • Clear the configuration except for security information and identification information. • Clear disk group configuration information and virtual disk configuration information only. CAUTION: As soon as you run this command, the existing storage array is deleted.
Parameters None Notes When you retrieve a controller health image from the RAID controller module cache to a host, a flag is set on the RAID controller module to indicate that the controller health image does not need to be retrieved. This setting persists for 48 hours. If a new controller health image occurs during that period, the new controller health image is saved to the RAID controller module cache and overwrites any previous controller health image data in the cache.
Parameters None. Clear Storage Array Recovery Mode Description This command forces a storage array to exit recovery mode. Syntax clear storageArray recoveryMode Notes Recovery mode is entered during start-of-day operations when the system configuration is cleared and a valid on-board backup is available. This mode is exited by either restoring the system configuration from a backup location, or by clearing the existing on-board backups.
NOTE: You can use any combination of alphanumeric characters, hyphens, and underscores for the names. Command names can have a maximum of 30 characters. If you exceed the maximum character limit, replace square brackets ([ ]) with angle brackets (< >) to overcome this limitation. Clear Virtual Disk Unreadable Sectors Description This command clears the unreadable sector information from one or more virtual disks.
Parameters Parameter Description enable Enable automatic collection of support bundles when a critical MEL event is detected. disable Disable automatic collection of support bundles where the feature was previously enabled. all Apply the command to all storage arrays detected from the host. storageArrayName Apply the command to the named storage array. data Store the data generated by the command at the location specified by the directorypath.
Description This command creates a new, empty consistency group that can contain snapshot groups. You must add the snapshot groups using the set consistencyGroup addCGMember command.
Parameter Description • • • • • startTime scheduleInterval endDate timesPerDay timeZone See the Notes section for information explaining how to use these options. rollBackPriority Determines whether system resources should be allocated to the rollback operation at the expense of system performance. A value of high indicates that the rollback operation is prioritized over all other host I/O. A value of low indicates that the rollback operation should be performed with minimal impact to host I/O.
Create Consistency Group Snapshot Image Description This command creates a new snapshot image for each base virtual disk that is a member of a snapshot consistency group. Syntax create cgSnapImage consistencyGroup="consistencyGroupName" Parameter Parameter Description consistencyGroup The name of the consistency group for which you are creating snapshot images. Enclose the consistency group name in double quotation marks (" ").
members=(baseVirtualDisk:repositoryVirtualDisk...
Notes You can use any combination of alphanumeric characters, underscore (_), hyphen (-), and pound (#) for the names. Names can have a maximum of 30 characters. If you do not specify the repositoryVolType or readOnly parameters, the MD storage management software selects the repositories for the consistency group snapshot virtual disk. If the disk group or disk pool where the base virtual disk resides does not have enough space, this command fails.
Syntax create mapping cgSnapVirtualDisk="snapVirtualDiskName" (host="hostName" | hostGroup=("hostGroupName" | defaultGroup)) Parameters Parameter Description cgSnapVirtualDisk The name of the consistency group snapshot virtual disk for which you want to create a logical mapping. Enclose the consistency group snapshot virtual disk name in double quotation marks (" "). host The name of a host to which you want to create a logical mapping. Enclose the host name in double quotation marks (" ").
enclosureLossProtect=(TRUE | FALSE) drawerLossProtect=(TRUE | FALSE) securityType=(none | capable | enabled)] [dataAssurance=(none | enabled)] Parameters Parameter Description physicalDisks The physical disks that you want to assign to the disk group that you want to create.

Parameter Description owner, the RAID controller module firmware determines the owner. cacheReadPrefetch The setting to turn on or turn off cache read prefetch. To turn off cache read prefetch, set this parameter to FALSE. To turn on cache read prefetch, set this parameter to TRUE. segmentSize The amount of data (in KB) that the RAID controller module writes on a single physical disk in a virtual disk before writing data on the next physical disk. Valid values are 8, 16, 32, 64, 128, 256, or 512.
The cacheReadPrefetch command lets the RAID controller module copy additional data blocks into cache while the RAID controller module reads and copies data blocks that are requested by the host from the physical disks into cache. This action increases the chance that a future request for data can be fulfilled from cache. CacheReadPrefetch is important for multimedia applications that use sequential data transfers.

This parameter has these values: • • enabled—Automatic resynchronization is turned on. You do not need to do anything further to resynchronize the primary virtual disk and the secondary virtual disk.
[capacity=capacityValue]))] [repositoryFullPolicy=(failBaseWrites | purgeSnapImages)] [rollbackPriority=(highest | high | medium | low | lowest)] [repositoryFullLimit=percentValue] [autoDeleteLimit=numberOfSnapImages]| [enableSchedule=(TRUE | FALSE)] [schedule (immediate | snapshotSchedule)] Parameters Parameter Description userLabel The alphanumeric identifier (including - and _) that you want to give the new snapshot group. Enclose the snapshot group identifier in double quotation marks (" ").
Parameter Description selected to purge the snapshot images for the repository full policy. The default value is 32. Notes Each snapshot group user label must be unique. You can use any combination of alphanumeric characters, underscore (_), hyphen(-), and pound (#) for the user label. User labels can have a maximum of 30 characters. To create a snapshot group, you must have an associated repository virtual disk in which you store the snapshot images.
Failed The snapshot group has encountered a problem that has made all snapshot images in the snapshot group unusable. For example, certain types of repository virtual disk failures can cause a Failed state. To recover from a Failed state use the revive snapGroup command. Create Snapshot Image Description This command creates a new snapshot image in one or more existing snapshot groups.
Create Snapshot (Legacy) Virtual Disk Description This command creates a snapshot virtual disk. When you use this command, you can define the snapshot virtual disk in one of three ways: • User-defined physical disks • User-defined disk group • User-defined number of physical disks for the snapshot virtual disk If you choose to define a number of physical disks, the RAID controller module firmware chooses which physical disks to use for the snapshot (legacy) virtual disk.
[enableSchedule=(TRUE | FALSE)] [schedule=(immediate | snapshotSchedule)] Parameters Parameter Description baseVirtualDisk The name of the base virtual disk from which you want to take a snapshot (legacy). Enclose the base virtual disk name in double quotation marks (" "). repositoryRAIDLevel Use this parameter when you create a new disk group. The RAID level for the snapshot (legacy) repository disk group. Valid values are 0,1, 5, or 6.
Parameter Description enclosureLossProtect The setting to enforce enclosure loss protection when you create the snapshot (legacy) repository virtual disk. To enforce enclosure loss protection, set this parameter to TRUE. The default setting is FALSE. physicalMediaType The type of physical disk media that you want to use for the disk group. Valid physical disk media consists of: • • • • HDD—Use this option when you have hard physical disks in the expansion enclosure.
Parameter Description repository is nearing full. Use integer values. For example, a value of 70 means 70 percent. The default value is 50. repositoryPercentOfSource The size of the snapshot (legacy) repository virtual disk as a percentage of the source virtual disk. Use integer values. For example, a value of 40 means 40 percent. The default value is 20. repositoryUserLabel The name to give to the snapshot (legacy) repository virtual disk.
You can use any combination of alphanumeric characters, underscore (_), hyphen (-), and pound (#) for the names. Names can have a maximum of 30 characters. One technique for naming the snapshot (legacy) virtual disk and the snapshot (legacy) repository virtual disk is to add a hyphenated suffix to the original base virtual disk name. The suffix distinguishes between the snapshot (legacy) virtual disk and the snapshot (legacy) repository virtual disk.
startDate A specific date on which you want to create a snapshot (legacy) virtual disk and perform a copy-on-write operation. The format for entering the date is MM:DD:YY. If you do not provide a start date, the current date is used. An example of this option is startDate=06:27:11. scheduleDay A day of the week on which you want to create a snapshot (legacy) virtual disk and perform a copy-on-write operation.
To remove a schedule, use the delete virtualDisk command with the schedule parameter. The delete virtualDisk command with the schedule parameter deletes only the schedule, not the snapshot (legacy) virtual disk. Create Snapshot Virtual Disk Description This command creates a snapshot virtual disk for snapshot images of a base virtual disk.
Parameter Description where xxxx represents a four digit numerical value. Enclose the snapshot virtual disk name in double quotation marks (" "). repositoryFullLimit The percentage of repository capacity at which you receive a warning that the snapshot repository virtual disk is nearing full. Use integer values. For example, a value of 70 means 70 percent. The default value is 75. Notes You can use any combination of alphanumeric characters, underscore (_), hyphen (-), and pound (#) for the names.
Parameters Parameter Description userLabel The alphanumeric identifier (including - and _) that you want to name the new SSD cache. Enclose the identifier in double quotation marks (" "). You can use any combination of alphanumeric characters, underscore (_), hyphen (-), and pound (#) for the identifier. Identifiers can have a maximum of 30 characters. physicalDisks The physical disks that you want to use to create the SSD cache.
Only virtual disks created using hard disk physical disks can use the SSD cache. You cannot enable SSD cache on snapshot (legacy) virtual disks or snapshot images. If all of the SSDs in the SSD cache are data assurance (DA)-capable and the DA premium feature is enabled, DA is automatically enabled for the SSD cache and cannot be disabled. In addition, you cannot add non-DA capable SSDs to a DA-enabled SSD cache.
Additional Information To use this command successfully, you need to have enough SES drives to create atleast one disk group. The RAID controller module firmware creates a lock that restricts access to the SES drives. SES drives have a state called Security Capable. When you create a security key, the state is set to Security Enabled, which restricts access to all SES drives that exist within the storage array. You can have a storage array configuration with more than one set of encrypted disk groups.
NOTE: You can have a maximum of eight virtual disk copies in progress at one time. If you try to create more than eight virtual disk copies at one time, the RAID controller modules return a status of Pending until one of the virtual disk copies that is in progress finishes and returns a status of Complete.
Parameter Description copyPriority Specifies the priority that a virtual disk copy has relative to host I/O activity. Valid entries are highest, high, medium, low, or lowest. NOTE: CopyPriority defines the amount of system resources used to copy the data between the source virtual disk and target virtual disk of a virtual disk-copy pair.
Delete Consistency Group Description This command deletes a snapshot consistency group in two ways: • You can delete both the consistency group and the repository virtual disks contained by the consistency group. • You can delete only the consistency group and leave the repository virtual disks that are contained by the consistency group intact.
Parameter Parameter Description consistencyGroup The name of the consistency group from which you want to delete the snapshot images. Enclose the consistency group name in double quotation marks (" "). deleteCount The number of snapshot images that you want to delete from the consistency group. Use integer values.

Parameter Description virtual disks, set this parameter to TRUE. The default value is FALSE. Notes You can delete a snapshot group if it is empty or if it contains snapshot images. All of the snapshot images in the snapshot group are deleted along with the snapshot group. If any existing snapshot image within the snapshot group has an associated view, each view is stopped and detached from the snapshot image. When you delete a snapshot group the associated repository virtual disk is also deleted.
Parameter Description snapshot images until reaching the number that you enter. If the number that you enter is greater than the actual number of all of the snapshot images in the snapshot group, all of the snapshot images will be deleted. The snapshot group is left empty. retainCount The number of snapshot images that you want to keep in the snapshot group. Use integer values. This parameter keeps the most recent snapshot images in the snapshot group and deletes older snapshot images.
Delete Snapshot (Legacy) Virtual Disk Description This command deletes one or more snapshot (legacy) virtual disks or snapshot (legacy) repository virtual disks. You can also use this command to remove schedules for creating snapshots (legacy). CAUTION: Possible damage to the storage array configuration – All of the data in the virtual disk is lost as soon as you run this command. Syntax delete (virtualDisk [virtualDiskName] | virtualDisks [virtualDiskName1 ...
Parameters Parameter Description snapVirtualDisk The name of the snapshot virtual disk that you want to delete.

To keep standalone disk groups intact, set this parameter to FALSE. schedule Deletes only the schedule.
Parameter Description force Use this parameter to force the immediate deletion of a virtual disk even if the RAID controller modules are performing other operations. To immediately force the deletion of a virtual disk, set this parameter to TRUE. To wait until the RAID controller modules have finished performing other operations, do not use this parameter or set this parameter to FALSE.
Parameters Parameter Description controller RAID controller module on which to run the diagnostic tests. Valid RAID controller module identifier values are 0 and 1. The identifier value is 0 for the RAID controller module on the top and 1 for the RAID controller module on the bottom when viewed from the rear of the enclosure. You must put brackets ([ ]) around the RAID controller module identifier. If you do not specify a RAID controller module, the MD storage management software returns a syntax error.
This command runs diagnostic tests on the copper cables between the iSCSI Host interface cards and a RAID controller module. You can run diagnostics on a selected port or all ports. The ports must be able to support the cable diagnostics.
– When the cable status is OK, the approximate lengths of the cable pairs are returned. The lengths of the cable pairs are shown as a range (L1-L2), which are the shortest and the longest lengths of the cable pairs. – If the cable status is Open or Short, the approximate distance to the failure in the cable pairs. If there is one failure, the length is reported for that cable pair. If there is more than one failure, the information returned is both the shortest and longest lengths to the failures.
Syntax disable storageArray (featurePack | feature=featureAttributeList) The featureAttributeList can be one or more of these attribute values. If you enter more than one attribute value, separate the values with a space.
Additional Information If you specify the remoteReplication parameter, this command disables the Remote Replication premium feature and takes away the structure of the replication repository virtual disk. If you disable the High Performance Tier feature, all of the included features are disabled.
Download Enclosure Management Module Firmware Description This command downloads firmware for the enclosure management module. Syntax download (allEnclosures | enclosure [enclosureID]) firmware file="filename" Parameters Parameter Description enclosure Identifies the enclosure to which to load new firmware. Enclosure ID values are 0 to 99. You must put brackets ([ ]) around the enclosure ID value.
You can use this command to test the firmware on one physical disk before installing the firmware on all of the physical disks in a storage array. (Use the Download Storage Array Physical Disk Firmware command to download firmware on all of the physical disks in the storage array. See Download Storage Array Physical Disk Firmware.) This command blocks all I/O activity until the download finishes or fails.
Parameters Parameter Description NVSRAM Specifies that you want to download a file with NVSRAM values when you download a firmware file. You must not put brackets around this parameter. Include a comma after the term firmware. file File path and name of the file that contains the firmware. Valid file names must end with a .dlp extension. You must put quotation marks (" ") around the file name. NVSRAM-filename File path and name of the file that contains the NVSRAM values.
Additional Information When you run this command, you can download more than one firmware image file to the physical disks in a storage array. The number of firmware image files that you can download depends on the storage array. The MD storage management software returns an error if you try to download more firmware image files than the storage array can accept. You can schedule downloads for multiple physical disks at the same time, including multiple physical disks in a redundant disk group.
Parameter Description fails, you can bypass the failure by using this parameter when running the command. Before any download, the RAID controller module checks the event log to determine if an event has occurred that might prevent the new NVSRAM from successfully downloading. If such an event has occurred, the RAID controller module normally does not download new NVSRAM. This parameter forces the RAID controller module to download new NVSRAM. The default value is FALSE.
Enable Disk Pool Security Description This command converts a non-secure disk pool to a secure disk pool. Syntax enable diskPool [diskPoolName] security Parameter Parameter Description diskPool The alphanumeric identifier (including - and _) of the disk pool that you want to place in the Security Enabled state. Enclose the disk pool identifier in square brackets ([ ]). Notes All of the physical disks that comprise the disk pool must be security capable.
NOTE: ODX provides a way to transfer data without using buffered read and buffered write operations and does not require direct host involvement with the data transfer operation. When ODX is not enabled, data is read from the source storage to the host, and then written to the target storage from the host. With ODX enabled, the data transfer operations are directly managed by the storage infrastructure. The data is moved directly from the source storage to the target storage without going through the host.

Enclose the virtual disk name in double quotation marks (" "). asyncRemoteReplicationGroup The name of an existing remote replication group that you want to use to contain the remote replicated pair. Enclose the remote replication group name in double quotation marks (" "). primaryVirtualDisk The name of an existing virtual disk on the local storage array that you want to use for the primary virtual disk.
Parameter Parameter Description addPhysicalDisks The setting to add new physical disks to the virtual disk. For dense expansion enclosures, specify the enclosure ID value, the drawer ID value, and the slot ID value for the physical disk. For non-dense expansion enclosures, specify the enclosure ID value and the slot ID value for the physical disk. Enclosure ID values are 0 to 99. Drawer ID values are 0 to 4. Slot ID values are 0 to 31.
Parameter Description file="C:\Array Backups \DBMbackup_03302010.dbm". This command does not automatically append a file extension to the saved file. You must specify a file extension when entering the file name. validator The alphanumeric security code required to restore a storage array to an existing configuration. Use the save storageArray dbmValidator command to generate the required validation information XML file.
Modify Disk Pool Description This command adds capacity to a disk pool or changes the RAID controller module ownership for the entire disk pool. These two operations are mutually exclusive. Syntax set diskPool [diskPoolName] (addPhysicalDisks=[enclosureID1,drawerID1,slotID1 ... enclosureIDn,drawerIDn,slotIDn] | addCapacity=(diskPoolCapacity)) [owner=(0 | 1)] Parameters Parameter Description addDrives Identifies multiple physical disks to add to the disk pool.
NOTE: Removing the drive letter of the associated virtual disk(s) in Windows or unmounting the virtual drive in Linux helps to guarantee a stable copy of the drive for the virtual copy. Syntax recopy virtualDiskCopy target [targetName] [source [sourceName]] [copyPriority=(highest | high | medium | low | lowest) targetReadOnlyEnabled=(TRUE | FALSE)] copyType=(online | offline) Parameters Parameter Description target Name of the target virtual disk for which to reinitiate a virtual disk copy operation.
Parameter Description reinitiate a virtual disk copy without a snapshot, set this parameter to offline. Recover disabled drive ports Description This command is used to tell the controller that corrective action has been taken to recover from a miswire condition. The controller will re-enable any SAS ports that were disabled when a mis-wire was detected.
Parameters Parameter Description physicalDisk or physicalDisks The physical disks that you want to assign to the disk group that will contain the virtual disk that you want to recover. For dense expansion enclosures, specify the enclosure ID value, the drawer ID value, and the slot ID value for each physical disk that you assign to the virtual disk. For non-dense expansion enclosures, specify the enclosure ID value and the slot ID value for each physical disk that you assign to the virtual disk.
segmentSize The amount of data (in KB) that the RAID controller module writes on a single physical disk in a disk group before writing data on the next physical disk. Valid values are 8, 16, 32, 64, 128, 256, or 512. dssPreallocate The setting to turn on or turn off allocating virtual disk storage capacity for future segment size changes. To turn on allocation, set this parameter to TRUE. To turn off allocation, set this parameter to FALSE. SSID The storage array subsystem identifier of a virtual disk.
NOTE: The MD storage management software collects recovery profiles of the monitored storage arrays and saves the profiles on a storage management station. The physicalDisk parameter supports both dense expansion enclosures and non-dense expansion enclosures. A dense expansion enclosure has drawers that hold the physical disks. The drawers slide out of the expansion enclosure to provide access to the physical disks. A non-dense expansion enclosure does not have drawers.
If the virtual disk is in an environment where a single user is transferring large units of data (such as multimedia), performance is maximized when a single data transfer request is serviced with a single data stripe. (A data stripe is the segment size that is multiplied by the number of physical disks in the disk group that are used for data transfers.) In this case, multiple physical disks are used for the same request, but each physical disk is accessed only once.

For supported software, refer to the Supported Management Software section of the Dell™ PowerVault™ MD Series Support Matrix at Dell.com/powervaultmanuals. Reduce Disk Pool Capacity Description This command reduces the capacity of the disk pool by logically removing the physical disks from the pool.
physical disks and the data that existed on them is redistributed across the remaining physical disks in the disk pool. The capacity of the disk pool is decreased by the capacity of the physical disks that you remove. Removing physical disks from a disk pool is always carried out as a background task and the virtual disks remain fully accessible during this operation. The progress of the removal operation is reported as part of the long running operations status.
Syntax create snmpTrapDestination trapReceiverIP=ipAddress communityName="communityName" [sendAuthenticationFailureTraps=(TRUE | FALSE)] Parameters Parameter Description trapReceiverIP The IP address of the SNMP manager to which you want to send trap messages. communityName The name of the SNMP community for which you want to send trap messages. sendAuthenticationFailureTraps This parameter turns on or turns off sending authentication failure messages to an SNMP manager.

Enclose the identifier in square brackets ([ ]). If the SSD cache name contains special characters or consists only of numbers, you also must enclose the identifier in double quotation marks (" ") inside square brackets. userLabel The new name for the SSD cache.
Parameter Description verbose Captures progress details, such as percent complete, and shows the progress detail information as virtual disk consistency is being repaired. To capture progress details, set this parameter to TRUE. To prevent capturing progress details, set this parameter to FALSE.
Parameter Description failPhysicalDisk This parameter causes the physical disk that you are replacing to be failed after the data has been copied to the replacement physical disk. This parameter can be used only when the copyPhysicalDisk parameter is used. Reset iSCSI IP Address Description This command resets the IP address for the remote storage array to re-establish connection with the local storage array.
Reset Physical Disk This command power cycles a physical disk in a disk group or a disk pool to aid in the recovery of a physical disk that is exhibiting inconsistent or non-optimal behavior. By power cycling a physical disk, some errors that cause inconsistent or non-optimal behavior can be cleared. This avoids replacing a physical disk when it is experiencing only a transient, non-fatal error, and the physical disk can remain operational.
NOTE: The physicalDisk parameter supports both dense expansion enclosures and non-dense expansion enclosures. A dense expansion enclosure has drawers that hold the physical disks. The drawers slide out of the expansion enclosure to provide access to the physical disks. A non-dense expansion enclosure does not have drawers. For a dense expansion enclosure, you must specify the identifier (ID) of the expansion enclosure, the ID of the drawer, and the ID of the slot in which a physical disk resides.
Additional Information The RAID controller module that receives the reset RAID controller module command resets the RAID controller module specified. For example, if the reset RAID controller module command is sent to RAID controller module 0 to request a reset of RAID controller module 0, then RAID controller module 0 reboots itself by doing a soft reboot.
Parameter Description sampleType This parameter is optional. The default value for sampleType is all. • • • • all—Data for all three sample types are reset. mostRecent—Statistics are reset for the most recent 50 resynchronization samples. longestSyncTime—Statistics are reset for the most recent 20 longest resynchronization samples. errors—Statistics are reset for the most recent 20 failed resynchronization samples. Notes Statistics are reset for replicated virtual disks in the Primary role.
Parameter Description enclosure. Use the controller parameter only for RAID controller modules with batteries. NOTE: If you do not specify a RAID controller module, the age is reset for the storage array battery or both RAID controller module batteries. If you specify a RAID controller module, then the age for only that RAID controller module battery is reset. Reset Storage Array iSCSI Baseline Description This command resets the iSCSI baseline for the storage array to 0.
Parameters None. Reset Storage Array Virtual Disk Distribution Description This command reassigns (moves) all virtual disks to their preferred RAID controller module. Syntax reset storageArray virtualDiskDistribution Parameters None. CAUTION: Ensure that the multipath driver is running before you use this command, or the virtual disk is not accessible. NOTE: Under certain host operating system environments, you might be required to reconfigure the multipath host physical disk.
Parameter Description • An identifier for the snapshot image in the consistency group. The identifier for the snapshot image can be one of these: • An integer value that is the sequence number of the snapshot in the consistency group. • NEWEST - Use this option when you want to show the latest snapshot image created in the consistency group. • OLDEST - Use this option when you want to show the earliest snapshot image created in the consistency group.
Parameter Description characters, the primary virtual disk name must also be enclosed in double quotation marks (“ ”). writeConsistency The setting to identify the virtual disks in this command that are in a write-consistency group or are separate. For the virtual disks to be in the same write-consistency group, set this parameter to TRUE. For the virtual disks to be separate, set this parameter to FALSE.
Resume Snapshot Image Rollback Description This command resumes a rollback operation that has entered a paused state. A rollback operation can enter a paused state due to processing errors, which causes a Needs Attention condition for the storage array. If the rollback operation cannot be resumed, the selected snapshot virtual disk reverts to a paused state, and the Needs Attention condition is displayed. NOTE: You cannot use this command for snapshot images involved in online virtual disk copy.
For example, if you want to restart a rollback operation for snapshot image 12345 in a snapshot group that has the name snapgroup1, you would use this command: resume snapImage ["snapgroup1:12345"] rollback; Resume Snapshot (Legacy) Rollback Description NOTE: With firmware version 7.83, the order of the terms in the syntax is changed to be consistent with other commands. Replace the deprecated command syntax with the new command syntax.
Parameters Parameter Description snapVirtualDisk The name of the specific snapshot virtual disk for which you want to resume a rollback operation. Enclose the snapshot virtual disk identifier in square brackets ([ ]). If the snapshot virtual disk identifier has special characters, you must also enclose the snapshot virtual disk identifier in double quotation marks (" "). snapImage The name of the snapshot image for which you want to resume snapshot virtual disk operations.
Resume SSD Cache Description This command restarts the caching for all virtual disks using the SSD cache that was temporarily stopped with the suspend ssdCache command. Syntax resume ssdCache [ssdCacheName] Parameter Parameter Description ssdCache The alphanumeric identifier (including - and _) of the SSD cache that you want to resume. Enclose the identifier in square brackets ([ ]).
Revive Disk Pool Description This command forces a disk pool and its associated physical disks to the Optimal state. CAUTION: Correct use of this command depends on the data configuration on all of the physical disks in the disk pool. Do not try to revive a disk pool unless you are supervised by your Technical Support representative. Syntax revive diskPool [diskPoolName] Parameter Parameter Description diskPool The alphanumeric identifier (including - and _) of the disk pool that you want to revive.

If the snapshot group is not in a Failed state, the firmware displays an error message and does not run this command. Syntax revive snapGroup [snapGroupName] Parameter Parameter Description snapGroup The alphanumeric identifier (including - and _) of the snapshot group that you want to set to the Optimal state. Enclose the snapshot group identifier in square brackets ([ ]).
Save Enclosure Log Data Description This command saves the enclosure log sense data to a file. Log sense data is maintained by the environmental cards for each enclosure. Not all of the environmental cards contain log sense data. Syntax save allEnclosures logFile="filename" Parameter Parameter Description logFile Name of the file to which to save the log sense data. You must put quotation marks (" ") around the file name.
NOTE: This command retrieves from both RAID controller modules the IOC dump log data and the IOC dump metadata. Using a 7zip file format, the retrieved data is archived and compressed into a single file with a file name of your choice. The 7zip archive file contains the following: filename+”IOCLog”+[A|B].gz – the IOC logs retrieved from RAID controller module 0 or RAID controller module 1 if available filename+”IOCLogInfo”+[A|B].
Parameters Parameter Description controller RAID controller module with the NVSRAM values to save. Valid RAID controller module identifier values are 0 and 1.

Notes When you use this command, you can specify one or more optional parameters. Synchronization priority defines the amount of system resources that are used to synchronize the data between the primary virtual disks and the secondary virtual disks of a replication relationship. If you select the highest priority level, the data synchronization uses the most system resources to perform the full synchronization, which decreases the performance for host data transfers.
Parameter Description must enclose the virtual disk name in double quotation marks (" ") inside square brackets. syncInterval Specify the length of time between automatically sending updates of modified data from the local storage array to the remote storage array. You can specify the length of time in minutes, hours, or days.

(You can enter more than one virtual disk name if you use the virtualDisks parameter).
Parameter Description rollbackPriority Determines whether system resources must be allocated to the rollback operation at the expense of system performance. A value of 0 indicates that the rollback operation is prioritized over all other host I/O. A value of 4 indicates that the rollback operation must be performed with minimal impact to the host I/O. Notes When you use this command, you can specify one or more of the optional parameters.
Parameter Description scheduleInterval Amount of time, in minutes that defines a minimum between two copy-on-write operations. It is possible for you to create a schedule in which you have overlapping copy-on-write operations because of the duration of a copy operation. You can ensure that copy-on-write operations maintain a correct interval by using this option. The maximum value for the scheduleInterval option is 1440 minutes. For example: scheduleInterval=180.
NOTE: If you also use the scheduleInterval option, the firmware chooses between the timesPerDay option and the scheduleInterval option by selecting the lowest value of the two options. The firmware calculates an integer value for the scheduleInterval option by dividing 1440 by the scheduleInterval option value that you set. For example, 1440/180 = 8. The firmware then compares the timesPerDay integer value with the calculated scheduleInterval integer value and uses the smaller value.

configurations, this parameter includes all the virtual disks that are owned by both RAID controller modules within the storage array. Cache Flush Start and Cache Flush Stop When you define values to start a cache flush, a value that is too low increases the chance that data needed for a host read is not in the cache. A low value also increases the number of physical disk writes that are necessary to maintain the cache level, which increases system overhead and decreases performance.

When a security-capable physical disk is added to a secured disk group, it becomes security-enabled.
Parameter Description turn on unnamed discovery sessions. Set the parameter to FALSE to turn off unnamed discovery sessions. NOTE: Discovery is the process where initiators determine the targets that are available. Discovery occurs at power-on/initialization and also if the bus topology changes, for example, if an extra device is added. NOTE: An unnamed discovery session is a discovery session that is established without specifying a target ID in the login request.
Parameter Description NOTE: The maximum capacity is 250 GB. repositoryMaxCapacity Set the maximum capacity of the repository virtual disk.

Sample Script Files 13 This appendix provides sample scripts for configuring a storage array. These examples show how the script commands appear in a complete script file. You can copy these scripts and modify them to create a configuration unique to your storage array.
set virtualDisk["7"] mediaScanEnabled=false; set virtualDisk["7"] consistencyCheckEnabled=false; set virtualDisk["7"] modificationPriority=high; This example shows blank lines between the lines beginning with Show, Create, //Note, and create. The blank lines are included in this example only for clarity. Each command is actually written on one line in the script file; however, the size of this page causes the command text to wrap.
Configuration Script Example 2 This example creates a new virtual disk using the create virtualDisk command with user-defined physical disks in the storage array. Show "Create RAID 5 Virtual Disk 2 on existing Disk Group 2"; //This command creates the disk group and the initial virtual disk on that group.
