About The Command Line Interface 1 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.
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. storageArray is the host name or IP address of the storage array. parameters are the CLI parameters that define the environment and purpose of the command.
Table 1. Command Name Conventions Parameter Definition a|b pipe symbol indicating alternative ("a" or "b") italicized-words terminals [...] (square brackets) zero or one occurrence {...} (curly brackets) zero or more occurrences <...
[-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 • • • eventOnly— Only event information is included in the e-mail. profile— Event and array profile information is included in the e-mail. supportBundle— Event and support bundle information is included in the e-mail. NOTE: You can enter only one information argument each time you execute the command. If you want all of the information, you must run the command three times. -i Use with the -d parameter to display the IP address of the known storage arrays.
Parameter Definition everyEvent. If you set the-I parameter to either profile or supportBundle, this information is included with the e-mails with the frequency specified by the-q parameter. Valid frequency arguments are: • • • • • • everyEvent— Information is returned with every e-mail alert notification. 2— Information is returned no more than once every two hours. 4— Information is returned no more than once every four hours. 8— Information is returned no more than once every eight hours.
Parameter Definition array configuration and the relationship between the devices. Use the configuration file to reconstruct a storage array). -x (lowercase) Use to remove an SNMP trap destination or an e-mail address alert destination. The community is the SNMP community name for the trap, and the host is the IP address or DNS host name of the system to which you want the trap sent. -? Use this parameter to display usage information about the CLI commands.
When an exception occurs while executing a command, the CLI automatically saves the error information to a file named excprpt.txt. The CLI attempts to place excprpt.txt in the directory specified by the system property devmgr.datadir, which by default is the "client/data" directory under the main installation directory in Windows and the /var/opt/SM directory in Linux. If for any reason the CLI cannot place the file in the devmgr.datadir-specified directory, the CLI saves the excprpt.
Status Value Meaning 24 The wrong management station was specified. 25 The command was not available. 26 The device was not in the configuration file. 27 An error occurred while updating the configuration file. 28 An unknown host error occurred. 29 The sender contact information file was not found. 30 The sender contact information file could not be read. 31 The userdata.txt file exists. 32 An invalid -I value in the e-mail alert notification was specified.
This example shows how to run commands in a script file named scriptfile.scr on a storage array named Example. The -e parameter runs the file without checking syntax. Executing an SMcli command without checking syntax enables the file to run more quickly; however, the SMcli command may not execute correctly if the syntax is incorrect. SMcli -n Example -f scriptfile.scr -e This example shows how to run commands in a script file named scriptfile.scr on a storage array named Example.
About The Script Commands 2 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.
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 (such as, specifying the RAID level or availability of a disk group).
Object Type Identifier enclosure Enclosure ID virtualDisk Virtual disk user label or the World Wide Identifier (WWID) for the virtual disk (set command only) virtualDiskCopy Target virtual disk and, optionally, the source virtual disk user labels diskGroup Virtual disk group number Statement data is in the form of attribute=value (such as raidLevel=5), an attribute name (such as batteryInstallDate), or an operation name (such as consistencyCheck).
Command Syntax Description recover object {statement‑data} Re-creates an object from saved configuration data and the statement attributes (similar to the create command). recreate object {statement‑data} Restarts a snapshot operation using an existing snapshot virtual disk. You can change attributes before the operation is restarted. remove object {statement‑data} Removes a relationship from between objects. repair object {statement‑data} Repairs errors found by the check command.

NOTE: The capacity parameter returns an error if you specify a value greater than or equal to 10 without a space separating the numeric value and its unit of measure. (For example, 10 GB returns an error, but 9 GB does not return an error). Adding Comments To A Script File You can add comments to a script file in three ways: • The script engine interprets as a comment any text typed after two forward slashes (/ /) until an end‑of‑line character is reached.
Configuring A Storage Array 3 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.
Determining What Is On Your Storage Array Even when you create a configuration on a previously unconfigured storage array, you still need to determine the hardware and software features that must be included with the storage array. When you configure a storage array with an existing configuration, you must ensure that your new configuration does not inadvertently alter the existing configuration, unless you are reconfiguring the entire storage array.
profile command, but is constrained to the specific component. (The following commands are not complete commands. For information about a command, see the referenced section next to the command.
Using The Create Virtual Disk Command The create virtualDisk command enables you to create new virtual disks in the storage array in three ways: • Create a new virtual disk while simultaneously creating a new disk group to which you assign the physical disks. • Create a new virtual disk while simultaneously creating a new disk group to which the MD Storage Manager software assigns the physical disks. • Create a new virtual disk in an existing disk group.
NOTE: The capacity parameter returns an error if you specify a value greater than or equal to 10 without a space separating the numeric value and its unit of measure. (For example, 10 GB returns an error, but 10 GB does not return an error). The command in this example automatically creates a new disk group and a virtual disk with the name Engineering_1. The disk group has a RAID level of 5 (RAID 5). The command uses three physical disks to construct the disk group.
The diskGroup parameter is the number of the disk group in which you want to create a new virtual disk. If you do not know the disk group numbers on the storage array, you can use the show allVirtualDisks summary command. This command displays a list of the virtual disks and the disk groups to which the virtual disks belong. The userLabel parameter is the name you want to give to the virtual disk. The virtual disk name can be any combination of alphanumeric characters, hyphens, and underscores.
• Size of each segment on the physical disks After defining these parameters, the MD Storage Manager automatically creates the disk groups, virtual disks, and hot spares. The RAID controller modules assign disk group and virtual disk numbers as they are created. After MD Storage Manager creates the initial configuration, you can use the set virtualDisk command to define virtual disk labels. Before running the autoConfigure storageArray command, run the show storageArray autoConfigure command.
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.
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. View the current alert configuration settings using the following command: SMcli -d -i -s -w -v -S By default, all alert configuration settings are None. The following example shows how to set the mail server IP and the sender address configurations for SMTP alerts: SMcli -m 123.45.67.892 -F MyStorageArrayEvent@MyCompany.com or SMcli -m MyCompany.
the host types with which the RAID controller modules can communicate; it does not return a list of the hosts. The following examples show how to use the defaultHostType parameter and the hostTypeTable parameter: client>smcli 123.45.67.89 -c "show storageArray defaultHostType;" client>smcli 123.45.67.89 -c "show storageArray hostTypeTable;" The following example shows how to define a specific default host type: client>smcli 123.45.67.
1. Identify the location of the physical disks by enclosure ID and slot ID. 2. Set the hotSpare parameter to TRUE to enable the hot spare or FALSE to disable an existing hot spare. The following syntax is the general form of the command: set (physicalDisk [enclosureID,slotID] | physicalDisks [enclosureID0,slotID0 ... enclosureIDn,slotIDn] hotSpare=(TRUE | FALSE) The following example shows how to use this command to set hot spare physical disks: client>smcli 123.45.67.
5. Click OK. Configuring Alert Notifications You can use the Configure Alerts dialog box to set up an email alert notification in the event of an error on the network. Alert emails are sent to the specified global mail server and sender email addresses in the event of an error on the selected hosts of storage arrays. You can choose to be alerted to all problems or individual problems. 1.
Using The Snapshot Feature 4 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.
• 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. You can set up a schedule for a snapshot group to automatically create a snapshot image at a specific time in the future or on a regular basis.
• Snapshots created using the Snapshot Virtual Disk (Legacy) premium feature cannot be included in a consistency group. • A base virtual disk can reside on either a disk group or disk pool. Understanding Snapshot Repositories Repositories are system-created virtual disks used to hold write data for snapshots, snapshot groups and consistency groups. During creation of either group or write-enabled snapshot virtual disk, an associated repository is automatically created.
repositoryVirtualDisk="repos_XXXX" [repositoryFullPolicy=(failBaseWrites | purgeSnapImages) | rollbackPriority=(high | highest | medium | low | lowest)| repositoryFullLimit=percentValue | autoDeleteLimit=numberOfSnapImages] • If you attempt to create a snapshot image and either of the two conditions below are present, the creation might fail: – The base virtual disk that contains this snapshot image is a member of a Remote Replication group. – The base virtual disk is currently synchronizing.
Unique command syntax and naming rules apply. The name of a snapshot image has two parts separated by a colon (:): • identifier of the snapshot group • identifier of the snapshot image If you do not specify the repositoryVirtualDiskType or readOnly parameters, the repositories for the consistency group snapshot virtual disk will be selected automatically. If the disk group or disk pool where the base virtual disk resides does not have enough space, the command will fail.
where, consistencyGroup is the name of the consistency group for which you are creating snapshot images. Deleting A Snapshot Virtual Disk Or A Consistency Group Snapshot Virtual Disk You can use the following command to delete a snapshot virtual disk or a consistency group snapshot virtual disk. Optionally, you can also delete the repository members. delete cgSnapVirtualDisk ["snapVirtualDiskName"] [deleteRepositoryMembers=(TRUE | FALSE)]; where, snapVirtualDiskName is the snapshot you want to delete.
• Create Consistency Group Starting, Stopping And Resuming A Snapshot Rollback The command line interface allows you to: • start a rollback operation from multiple snapshot images concurrently • stop a rollback operation • resume a rollback operation When rolling back, the host will have immediate access to the new-rolled-back base virtual disk, but the existing base virtual disk will not allow the host read-write access once the rollback is initiated.
– The base virtual disk is currently in a synchronizing operation. The snapshot image creation completes as soon as the synchronization operation is complete.
This action frees repository capacity so it can be used to satisfy ongoing copy-on-write requirements for the remaining snapshot images. For other values, see Create Consistency Group. 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.
The oldest snapshot images in the snapshot group until the maximum number of images defined with the parameter is met. Deleting snapshot images frees repository capacity so it can be used to satisfy ongoing copy-on-write requirements for the remaining snapshot images. Adding A Member Virtual Disk To A Consistency Group To add a new base virtual disk to an existing consistency group, specify an existing repository virtual disk for the new consistency group member or create a new repository virtual disk.
To remove CGGroup_1, as well as all repository virtual disks: set consistencyGroup ["CGGroup_1"] removeCGMemberVirtualDisk=" payroll_backup" deleteRepositoryMembers=TRUE; Or omit the deleteRepositoryMembers parameter, which invokes the default value of preserving repository virtual disks: set consistencyGroup ["CGGroup_1"] removeCGMemberVirtualDisk=" payroll_backup"; Changing The Pre-read Consistency Check Setting Of An Overall Repository Virtual Disk Use the Pre-Read Consistency Check option to define a s
preReadConsistencyCheck The setting to turn on or turn off preread consistency checking. Turning on preread consistency checking verifies the consistency of RAID redundancy data for the stripes containing the read data. Preread consistency checking is performed on read operations only. To turn on preread consistency checking, set this parameter to TRUE. To turn off preread consistency checking, set this parameter to FALSE.
To decrease capacity, replace increaseRepositoryCapacity with decreaseRepository: set snapVirtualDisk ["snapVirtualDiskName"] decreaseRepositoryCapacity count=numberOfVirtualDisks Setting Snapshot Group Repository Virtual Disk Capacity To increase or decrease capacity of a snapshot group repository virtual disk, use the same basic command syntax as shown previously for the virtual disk repository, except use the set snapGroup command and supply the snapshot group name: set snapGroup ["snapGroupName"] incre
Using The Snapshot (Legacy) 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 (legacy) premium feature. If you are using the Snapshot Virtual Disk using PiT groups, see Using The Snapshot Feature.
Table 9. Snapshot Virtual Disk Components Component Description Source virtual disk Standard virtual disk from which the snapshot is created Snapshot virtual disk Point-in-time image of a standard virtual disk Snapshot repository virtual disk Virtual disk that contains snapshot metadata and copy-onwrite data for a particular snapshot virtual disk The following table lists the snapshot virtual disk commands and brief descriptions of what the commands do. Table 10.
• Define a disk group in which the snapshot repository virtual disk resides. Optionally define the capacity of the repository virtual disk. • Define the number of physical disks, but not specific physical disks, for the repository virtual disk. When using the create snapshotVirtualDisk command to create a snapshot virtual disk, the standard virtual disk name for the source virtual disk is the minimum information required.
1. Stop all I/O activity to the source. 2. Using your Windows system, flush the cache to the source. At the host prompt, type SMrepassist -f and press . See "SMrepassist Utility" in the Owner’s Manual for more information. 3. Remove the drive letter(s) of the source in Windows or unmount the virtual drive(s) in Linux to help guarantee a stable copy of the drive for the Snapshot.
See step 1 through step 4 in the preceding section, Preparing Host Servers To Create An Initial Snapshot Virtual Disk. The following example is the script file version of the command: create snapshotVirtualDisk sourceVirtualDisk= "Mars_Spirit_4" repositoryRAIDLevel=5 repositoryPhysicalDisks=(1,1 1,2 1,3 1,4 1,5); A minimal version of this command might look like the following example: client>smcli 123.45.67.
The following example is the script file version of the command: create snapshotVirtualDisk sourceVirtualDisk= "Mars_Spirit_4" repositoryDiskGroup=2 freeCapacityArea=2; Creating A Snapshot Virtual Disk By Specifying A Number Of Physical Disks With this version of the create snapshotVirtualDisk command, you must specify the number of physical disks and the RAID level for the snapshot repository virtual disk. This version of the create snapshotVirtualDisk command creates a new disk group.
Table 11. Snapshot Virtual Disk Parameters Parameter Description physicalDiskType Specifies the type of physical disk to use for the snapshot repository virtual disk. The type must be specified as Serial Attached SCSI (SAS). This parameter works only with the count-based repository method of defining a snapshot virtual disk. repositoryDiskGroup Specifies the disk group in which to build the snapshot virtual disk.
Parameter Description fail writes to the source virtual disk (failSourceWrites) or fail writes to the snapshot virtual disk (failSnapShot). The default value is failSnapShot. enableSchedule Turns on or off the ability to schedule a snapshot operation. To turn on snapshot scheduling, set the parameter to TRUE. To turn off snapshot scheduling, set the parameter to FALSE.
in quotation marks. The character string cannot contain a new line. Make sure that you use unique names or the RAID controller module firmware returns an error. One technique for naming the snapshot virtual disk and the repository virtual disk is to add a hyphenated suffix to the original name of the source virtual disk. The suffix distinguishes between the snapshot virtual disk and the repository virtual disk.
virtualDisk command to stop the copy‑on‑write operations. When you stop a snapshot virtual disk, the snapshot virtual disk and the repository virtual disk are still defined for the source virtual disk; only copy-on-write has stopped. The following example stops a snapshot virtual disk: client>smcli 123.45.67.
Re-creating A Snapshot Virtual Disk After first preparing the host server(s) as specified in the preceding procedure, use the following examples to re-create a virtual disk snapshot. Refer to steps 1 through 4 in the preceding section, Preparing Host Servers To Re-create A Snapshot Virtual Disk. The following example shows the command to restart a snapshot virtual disk: client>smcli 123.45.67.
Using The Virtual Disk Copy Feature 6 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 online help, the Deployment Guide, the MD Storage Manager online help, and the Administrator's Guide.
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.
1. Enable the Virtual Disk Copy feature. 2. Determine candidates for a virtual disk copy. 3. Create the target virtual disk and source virtual disk for a virtual disk copy. Enabling The Virtual Disk Copy Feature The first step in creating a virtual disk copy is to make sure the feature is enabled on the storage array. You need a feature key to enable the feature.
1. Stop all I/O activity to the source and target virtual disk. 2. Using your Windows system, flush the cache to both the source and the target virtual disk (if mounted). At the host prompt, type SMrepassist -f and press . See "SMrepassist Utility" in the Owner’s Manual for more information. 3.
Refer to steps 1 through 4 in the preceding section, Preparing Host Servers To Create A Virtual Disk Copy. The following example is the script file version of the command: create virtualDiskcopy source="Jaba_Hut" target= "Obi_1" copyPriority=medium targetreadonlyenabled=true; After the virtual disk copy operation is completed, the target virtual disk automatically becomes read-only to the hosts. Any write requests to the target virtual disk are rejected, unless you disable the read-only attribute.
• After the virtual disk copy has completed re-creating a virtual disk copy using the recopy virtualDiskCopy command When you create a virtual disk copy pair and after the original virtual disk copy has completed, the target virtual disk is automatically defined as read-only to the hosts. The read-only status of the target virtual disk ensures that the copied data on the target virtual disk is not corrupted by additional writes to the target virtual disk after the virtual disk copy is created.
Preparing Host Servers To Recopy A Virtual Disk 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.
Refer to steps 1 through 4 in the preceding section, Preparing Host Servers To Recopy A Virtual Disk. The following example is the script file version of the command: recopy virtualDiskCopy target ["Obi_1"] copyPriority=highest; Stopping A Virtual Disk Copy The stop virtualDiskCopy command enables you to stop a virtual disk copy that has a status of In Progress, Pending, or Failed.
About Snapshot (Legacy) Premium Features With Virtual Disk Copy • A source virtual disk for a virtual disk copy can be a standard virtual disk or a thin virtual disk (if supported in your firmware version). • A target virtual disk can be a standard virtual disk in a disk group or disk pool, or a snapshot (legacy) base virtual disk if the snapshot (legacy) premium feature is the only snapshot premium feature enabled on your storage array.
7 Using The Remote Replication Premium Feature 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).
completes, the system uses the point-in-time images on the secondary virtual disk to ensure that the data is maintained in a consistent state during subsequent synchronization operations to the secondary virtual disk. Replication Pairs And Replication Repositories Replicated pairs, comprising of a primary and secondary virtual disk, contain identical data copies as a result of data synchronization.
corrected (the secondary virtual disk is placed online or recovered to an Optimal status), then synchronization is required. The replicated pair then transitions to a Synchronization in Progress status. Resynchronization Data replication between the primary virtual disk and the secondary virtual disk in a replication relationship is managed by the RAID controller modules and is transparent to host machines and applications.
Remote Replication Requirements And Restrictions To use the standard Remote Replication premium feature, you must have: • Two storage arrays with write access and both these storage arrays must have sufficient space to replicate data between them. • Each storage must have a dual-controller Fibre Channel or iSCSI configuration (single-controller configurations are not supported).
In this command, asyncReplication is literal and is appended with the activation_key, which is provided by Dell. For example, if your activation key value is 999999: enable storageArray feature file="asyncReplication999999" Activating The Remote Replication Premium Feature Activating the Remote Replication premium feature prepares the storage arrays to create and configure replication relationships.
Changing Remote Replication Group Settings The set asyncRemoteReplicationGroup command lets you change settings for an existing replication group. The following parameters set synchronization and warning threshold values for the replication group. Changing the synchronization settings affects the synchronization operations of all replicated pairs within the remote replication group.
Suspending A Remote Replication Group Use the asyncRemoteReplicationGroup command to stop data transfer between a primary virtual disk and a secondary virtual disk in a replication relationship without disabling the replication relationship. Suspending a replication relationship group lets you control when the data on the primary virtual disk and data on the secondary virtual disk are synchronized.
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 synchronization statistics for member virtual disks to relative 0. show asyncRemoteReplicationGroup synchronizationProgress Shows progress of periodic synchronization of the replication group as a percentage. show asyncRemoteReplicationGroup summary Shows configuration information for one or more replication groups.
8 Using The Remote Replication (Legacy) Premium Feature 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.
In the event of a disaster or a catastrophic failure at the primary site, you can perform a role reversal to promote the secondary virtual disk to a primary role. Hosts then are able to read from and write to the newly promoted virtual disk, and business operations can continue.
Synchronous Write Mode Synchronous write mode provides the highest level security for full data recovery from the secondary storage array in the event of a disaster. Synchronous write mode does reduce host I/O performance. When this write mode is selected, host write requests are written to the primary virtual disk and then copied to the secondary virtual disk.
Resynchronization Data replication between the primary virtual disk and the secondary virtual disk in a replication relationship is managed by the RAID controller modules and is transparent to host machines and applications. When the RAID controller module owner of the primary virtual disk receives a write request from a host, the RAID controller module first logs information about the write to a replication repository virtual disk.
– • • A full synchronization at the lowest synchronization priority level takes approximately eight times as long as a full synchronization at the highest synchronization priority level. – A full synchronization at the low synchronization priority level takes approximately six times as long as a full synchronization at the highest synchronization priority level.
The activate storageArray feature=remoteReplication command provides three methods for defining the physical disks for your replication repository virtual disk: • • • You define each physical disk for the replication repository virtual disk by its enclosure ID and its slot ID. You define a disk group in which the replication repository virtual disk resides. You can optionally define the capacity of the replication repository virtual disk.
This example shows how to use the command in a script file: activate storageArray feature=remoteReplication repositoryDiskGroup=2 freeCapacityArea=2; Activating The Remote Replication (Legacy) Premium Feature By Specifying A Number Of Physical Disks With this version of the activate storageArray feature= remoteReplication command, you must specify the number of physical disks and the RAID level that you want for the replication repository virtual disk. This version of the command creates a new disk group.

Interaction With Other Premium Features You can run the Remote Replication (legacy) premium feature while running these premium features: • Snapshot—both standard Snapshot and Snapshot (legacy) premium features • Virtual Disk Copy When you run the Remote Replication (legacy) premium feature with other premium features, you must consider the requirements of the other premium features to ensure that you set up a stable storage array configuration.
Storage Partitioning Storage partitioning enables hosts to share access to virtual disks in a storage array. You create a storage partition when you define the following storage array assignments: • A host • A host group • Virtual disk-to-logical unit number (LUN) mapping The virtual disk-to-LUN mapping enables you to define which host group or host has access to a particular virtual disk in the storage array.
Maintaining A Storage Array 9 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.
Consistency mismatches Consistency errors are found, and a media error is forced on the block stripe so that it is found when the physical disk is scanned again. If consistency is repaired, this forced media error is removed. The result of this action is that the first ten consistency mismatches found on a virtual disk are reported to the MEL. Unfixable error The data could not be read and consistency information could not be used to regenerate it.

To clear persistent virtual disk reservations, run the following command: clear (allVirtualDisks | virtualDisk[virtualDiskName] | virtualDisks [virtualDiskName1" ... "virtualDiskNameN])reservations Synchronizing RAID Controller Module Clocks To synchronize the clocks on both RAID controller modules in a storage array with the host clock, run the following command: set storageArray time Locating Physical Disks At times, you might need to locate a specific physical disk.
Type of Information Description Current KB/second Current transfer rate in kilobytes per second (current means the number of kilobytes per second since the last time the polling interval elapsed, causing an update to occur) Maximum KB/second Highest data transfer value achieved in the current kilobyte-per-second statistic block Current IO/second Current number of I/Os per second (current means the number of I/Os per second since the last time the polling interval elapsed, causing an update to occur)
Defragmenting A Disk Group When you defragment a disk group, you consolidate the free capacity in the disk group into one contiguous area. Defragmentation does not change the way in which the data is stored on the virtual disks. As an example, consider a disk group with five virtual disks.
The ssdCacheName parameter names the cache group. Setting the updateExistingVirtualDisks parameter to TRUE enables SSD caching for all virtual disks in the storage array. The following restrictions apply: • A storage array can have only one SSD cache. • Only virtual disks created using physical disks can use the SSD cache. You cannot enable SSD cache on snapshot (legacy) virtual disks or snapshot images. • SSD caching does not support self-encrypting disks (SEDs).
The following additional SSD cache-related commands are available in this document: • Change SSD Cache Application Type • Blink SSD Cache • Rename SSD Cache • Resume SSD Cache • Show SSD Cache • Suspend SSD Cache Troubleshooting and Diagnostics If a storage array exhibits abnormal operation or failures, you can use the commands described in this section to determine the cause of the problems.
The test results contain a generic, overall status message and a set of specific test results. Each test result contains the following information: • Test (read/write/data loopback) • Port (read/write) • Level (internal/external) • Status (pass/fail) Events are written to the MEL when diagnostics are started and when testing is completed. These events help you to evaluate whether diagnostics testing was successful or failed and the reason for the failure.
Changing RAID Controller Module Ownership You can change which RAID controller module owns a virtual disk by using the set virtualDisk command. The following syntax is the general form of the command: set (allVirtualDisks | virtualDisk [virtualDiskName] | virtualDisks [virtualDiskName1 ... virtualDiskNameN] | virtualDisk owner=(0 | 1) Initializing A Physical Disk CAUTION: When you initialize a physical disk, all data on the physical disk is lost.
where, virtualDiskName is the identifier for the virtual disk. NOTE: Initializing a thin virtual disk may take an extremely long time. Redistributing Virtual Disks Redistributing virtual disks returns the virtual disks to their preferred RAID controller module owners. The preferred RAID controller module ownership of a virtual disk or disk group is the RAID controller module of an active-active pair that is designated to own the virtual disks.
Script Commands 10 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.
• You must enter spaces in the commands as they are shown in the command descriptions. • Brackets are used in two ways: – As part of the command syntax – To indicate which parameters are optional The description of each parameter tells you when you must put brackets around a parameter value. • Parentheses shown in the command syntax enclose specific choices for a parameter. That is, if you want to use the parameter, you must use one of the values shown in the parentheses.
For Linux, and when used in a script file, the name appears as the following: ["Engineering"] When you enter the World Wide Identifier (WWID) of an HBA host port, some usages require quotation marks around the WWID. In other uses, you must put angle brackets (< >) around the WWID. The description of the WWID parameter tells you if you must put quotation marks or angle brackets around the WWID. • Script commands must end with a semicolon (;).

Notes A consistency group is a logical entity that enables you to manage in batch form all of the snapshot images that you add to the collection. The consistency group is a collection of snapshot groups that have mutual consistency requirements or dependencies for their snapshot images. Any snapshot images that you create and use for this collection must be managed in accordance with the consistency dependencies.
completed successfully for all of the consistency group members, the operation fails and new snapshot images are not created. Normally, all members of a snapshot consistency group will have the same number of snapshot images. When you add a new member to a snapshot consistency group, that new member lacks the snapshot images that were previously created on the established members of the snapshot consistency group. This is not an error condition.
Parameter Description members The identifier of one base virtual disk or more than one base virtual disks that you want to add. The members identifier is comprised of the base virtual disk name concatenated with the repository virtual disk name. You must use a colon (:) between the two names. Enclose all of the member identifiers in parenthesizes. If you enter more than one member separated the members with a space.

If the virtual disk name has special characters, also enclose the virtual disk name in double quotation marks (“ ”). writeConsistency This parameter defines whether the virtual disks identified in this command are in a writeconsistency group or are separate.
Parameter Description square brackets ([ ]). If the remote replication group name has special characters, you also must enclose the remote replication group name in double quotation marks (" ") inside square brackets. If the remote replication group name consists only of numbers, such as "1002," you also must enclose the remote replication group name in double quotation marks (" ") inside square brackets.
Parameters Parameter Description asyncRemoteReplicationGroup The name of an existing remote replication group that you want to test. Enclose the remote replication group name in square brackets ([ ]). If the remote replication group name has special characters, you also must enclose the remote replication group name in double quotation marks (" "). testID The identifier for the diagnostic test you want to run.
Parameters Parameter Description file The file path and the file name to which you want to save the security key. For example, file="C:\Program Files\CLI\sup\seckey.slk" NOTE: You must add a file extension of .slk to the end of the file name. passPhrase A character string that encrypts the security key so that you can store the security key in an external file. Additional Information Your pass phrase must meet these criteria: • The pass phrase must be between eight and 32 characters long.
Sample Script Files 12 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.
The first line of text is the show string command. This command displays text bounded by quotation marks (" ") on a monitor screen when the script file runs. In this example, the text Create RAID 5 Virtual Disk 7 on existing Disk Group 1 serves as a title describing the expected results of running this script file. The line beginning //Create is a comment explaining that the purpose of this script file is to create a new virtual disk by using the create virtualDisk command on an existing disk group.
set virtualDisk["7"] mediaScanEnabled=false; set virtualDisk["7"] consistencyCheckEnabled=false; set virtualDisk["7"] modificationPriority=high; The command in this example, like the create virtualDisk command in the previous example, creates a new virtual disk. The significant difference between these two examples is that this example shows how you can define specific physical disks to include in the virtual disk.
CLI Command Updates 13 This chapter reflects new and updated commands that are available for use with Dell's PowerVault Modular Disk Series of storage arrays. NOTE: Not all commands are necessarily 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.
