CH A P T E R 1 Using the CLI This chapter introduces the HP StorageWorks MSA2000 Family command-line interface (CLI) and includes the following topics: ■ “Accessing the CLI” on page 15 ■ “Operation Modes” on page 16 ■ “Command Syntax” on page 25 ■ “Command Completion, Editing, and History” on page 28 ■ “Viewing Command Help” on page 29 ■ “Size of Devices and Logical Units” on page 29 ■ “Event Log” on page 30 Accessing the CLI The CLI software embedded in controller modules enables you to configure, monito
Operation Modes By default the CLI is an interactive application. When you are logged into the CLI, the CLI waits for a command to be entered and then responds to it. This singleoperation mode is known as interactive mode. The following example shows interactively starting a telnet session, logging into the CLI, executing a command to show free (available) disks, and exiting the CLI: $: telnet 172.22.5.
The following example shows the Perl Expect script showfree.exp that starts a telnet session, logs into the CLI, executes a command to show free disks, and exits the CLI: #!/usr/bin/expect set login [lindex $argv 1] set password [lindex $argv 2] set host [lindex $argv 3] set command [lindex $argv 4] spawn telnet $host expect "Login:" send "$login\r" expect "Password:" send "$password\r" send "$command\r" send "exit" expect eof The following shows a possible result of executing this script: $:./showfree.
The example below and continuing on the next page shows how to construct a script using a Perl library for telnet communication. use Net::Telnet; $mVer = "v.072006"; $mLine = "=========================================================="; $mStr = "Management Controller System Cloning Utility"; $nLine = "\n"; $cliDumpFile = "get_config_dump.
The example shows a Perl script for logging in. cLogin is called at the start of the script to log a user into the CLI. The script uses the command-line parameters specified as the IP address, username, and password. Once the user has been logged in, other commands can be sent to the CLI. The command below provides better scripting support. The first argument sets the output format to XML, which allows easier parsing.
DTD The following is Revision 1 of the DTD. Elements and attributes are described in the table on the following page.
Elements and attributes of the DTD are described in the following table. Element Description and Attributes RESPONSE The RESPONSE is the top level XML object. The request attributes contain the details of the request that was sent. The RESPONSE is a container for objects that are returned as part of the request. All commands have a status object as part of the RESPONSE which provides a message and return code. A return code of 0 indicates that the command was successful.
Element Description and Attributes ASC The association element provides a simple association description between two objects in the response. • A • B Example The following example shows the output of the show schedule-details command with the output first set to console and second set to api.
# set cli-parameters api #show schedule-details Sched1
00c0ff0a43010048f9ca2d4601000000 ss 3 none
Command Syntax This section describes syntax rules for CLI commands. ■ “Keywords and Parameters” on page 25 ■ “Disk Drive Syntax” on page 25 ■ “Virtual Disk Syntax” on page 26 ■ “Volume Syntax” on page 26 ■ “Volume Mapping Syntax” on page 27 ■ “Host Nickname Syntax” on page 27 Keywords and Parameters Command keywords must be entered in lowercase. Parameter values can be entered in uppercase and lowercase.
Virtual Disk Syntax You can specify virtual disks by using: ■ Virtual disk name. A user-defined, case-sensitive name that can include a maximum of 17 characters, but not comma, quotation mark ("), or backslash. A name that includes a space must be enclosed in quotation marks. To use a name that the CLI could interpret as an optional parameter, you must specify that parameter before the name parameter. ■ ■ Virtual disk serial number.
Host Nickname Syntax You can specify a nickname for a host-side port. A nickname is a case-sensitive name that can include a maximum of 15 characters, but not comma, quotation mark ("), or backslash. A name that includes a space must be enclosed in quotation marks. For example, MyHost. Volume Mapping Syntax You can specify the controller host ports and LUN to use in a volume mapping by using the syntax ports.LUN.
Command Completion, Editing, and History The CLI supports command completion, command editing, and command history. When using command completion, if you enter too few letters to uniquely identify a keyword, the CLI lists keywords that match the entered string and redisplays the string so you can complete it. The history contains all commands entered in the active CLI session. You can recall a command from the history, edit it, and run it.
Viewing Command Help To view brief descriptions of all commands that are available to the user level you logged in as, type: # help To view help for a specific command, type either: # help command # command ? To view information about the syntax to use for specifying disk drives, virtual disks, volumes, and volume mapping, type: # help syntax Size of Devices and Logical Units The size of disk drives and logical units such as virtual disks and volumes are presented in base 2 (binary) format, not base 10 (
Event Log A controller enclosure’s event log records all events that have occurred in or been detected by the controller modules and encompasses all field-replaceable units (FRUs) in the enclosure. Each event has one of the following levels, in decreasing severity: ■ Critical. Events that might affect data integrity or system stability. ■ Warning. Events that do not affect data integrity. ■ Informational. Events that show the change of state or configuration changes.
CH A P T E R 2 Command Categories Commands in this guide are organized alphabetically to make it easy to find a command by name. This chapter helps you find a command within a logical grouping, based on the command’s function. A command might be listed in more than one category. For more information about each command, see Chapter 3.

Counters and status can be reset to a good state for all enclosures, or for a specific enclosure whose status is Error as shown by the show expander-status command. Input clear expander-status [enclosure id] Parameter Description enclosure id Optional.
convert master-to-std Description Converts a specified master volume into a standard volume; that is, it disables the volume from accepting snapshots. You must delete all snapshots that exist for the master volume before converting it to a standard volume; otherwise, the command will fail. Input convert master-to-std volume Parameter Description volume Specifies the volume by its name or serial number. For the syntax to use, see “Volume Syntax” on page 26.
convert std-to-master Description Converts a standard volume to a master volume; that is, it enables the volume for snapshots and associates it with an existing snap pool. The standard volume and the snap pool must be owned by the same controller, though they can be on different virtual disks. Input convert std-to-master volume snap-pool volume Parameter Description volume Specifies the master volume by its name or serial number. For the syntax to use, see “Volume Syntax” on page 26.
create chap-record Description iSCSI only. Creates a record to enable authentication between the originator (initiator) and recipient (target) of a login request when CHAP is enabled. This command is permitted whether or not CHAP is enabled. The CHAP record can specify one name-secret pair to authenticate the originator only (one-way CHAP) or two pairs to authenticate both the originator and the recipient (mutual CHAP).
Example Create a one-way CHAP record to enable a storage system to authenticate a host initiator having IQN iqn.1991.05.com.microsoft-swlab-qle. # create chap-record name iqn.1991-05.com.microsoft:myHost.domain secret 123456abcDEF Success: created CHAP record for iqn.1991-05.com.microsoft:myHost.
create host-wwn-name Description FC and SAS only. Creates an entry for a host world wide port name (WWPN) and associates a nickname with the entry. This enables you to specify the nickname instead of the WWPN when mapping volumes to hosts. Input create host-wwn-name wwn wwpn name Parameter Description wwn wwpn Specifies a 16-hex-digit WWPN that corresponds to an HBA. name Specifies a nickname for the HBA. For the syntax to use, see “Host Nickname Syntax” on page 27.
create iscsi-host Description iSCSI only. Associates a nickname with an iSCSI host initiator’s node name. You can then use the nickname when mapping volumes to hosts. Input create iscsi-host name name nickname Parameter Description name name Specifies an iSCSI host initiator’s node name. This is typically the initiator’s IQN (iSCSI Qualified Name). This must not be an existing node name, as displayed with the show iscsi-hosts command; it must be one that you get from some other source of information.
create master-volume Description Creates a volume on a specified virtual disk, enables the volume for snapshots, and associates it with an existing snap pool. The volume and snap pool must be owned by the same controller. Input create master-volume vdisk vdisk size sizeMB|GB|TB snap-pool volume [lun LUN] name Parameter Description vdisk vdisk Specifies the virtual disk by name or serial number. For the syntax to use, see “Virtual Disk Syntax” on page 26.

map volume Description Creates a mapping whose settings override a volume’s default mapping. When a volume is created, it has a default mapping that specifies the controller host ports and access level that all connected hosts have to the volume, and the LUN presented to all hosts to identify the volume. By default, this mapping presents no LUN and allows no access for all hosts through all ports. The default mapping’s LUN value is referred to as the volume’s default LUN.
Parameter Description host host Optional. For FC and SAS, this specifies the host’s nickname or 16-hex-digit WWPN. For iSCSI, this specifies the iSCSI host initiator’s node name (typically the IQN) or nickname. For the nickname syntax to use, see “Host Nickname Syntax” on page 27. If this parameter is omitted, the mapping applies to the all-hosts mapping and applies to all hosts that are not explicitly mapped. access read-write|rw| read-only|ro| none Optional.

Input ping host-address [count] Parameter Description host-address Specifies the remote host’s IP address in dotted decimal form. count Optional. Specifies the number of packets to send. The default is 4 packets. You should use a small count because the command cannot be interrupted. Example Send two packets to the remote computer at 10.0.0.
rescan Description This command forces rediscovery of attached disk drives and enclosures. If both Storage Controllers are online, it also forces re-evaluation of the enclosure IDs of attached drive enclosures, so that IDs are assigned based on controller A’s enclosure cabling order. A manual rescan may be needed after system power-up to display enclosures in the proper order. A manual rescan is not required to detect when drives are inserted or removed; the controllers do this automatically.
reset host-channel-link Description FC only. For a system using loop (FC-AL) topology, this command issues a loop initialization primitive (LIP) for specified controller ports. Input reset host-channel-link channel channels [controller a|b|both] Parameter Description channel channels Specifies a host port number or a comma-separated list of host port numbers such as 0,1. controller a|b|both Optional. Specifies whether to issue the LIP from controller A, controller B, or both.
reset snapshot Description Deletes the data in a snapshot and resets it to the current data in the associated master volume. The snapshot's volume characteristics are not changed. The command prompts you to unmount the snapshot from the host operating system before performing the reset; leaving it mounted can cause data corruption. Caution – All data represented by the snapshot as it exists prior to issuing this command is lost.
restart Description Restarts the Storage Controller or Management Controller in either or both controller modules. If you restart a Storage Controller, it attempts to shut down with a proper failover sequence, which includes stopping all I/O operations and flushing the write cache to disk, and then the controller restarts. The Management Controllers are not restarted so they can provide status information to external interfaces.
Example Restart the Management Controller in controller A, which you are logged in to. # restart mc a During the restart process you will briefly lose communication with the specified management Controller(s). Continue? yes Info: Restarting Local MC A... From controller A, restart the Storage Controller in controller B. # restart sc b Success: SC B restarted.
restore defaults Description Note – This command should only be used by service technicians, or with the advice of a service technician. Restores the manufacturer's default configuration to the controllers. When the command informs you that the configuration has been restored, you must restart the controllers for the changes to take effect. After restarting the controllers, hosts might not be able to access volumes until you re-map them.
rollback master-volume Description Rolls back (reverts) the data on a master volume to the data that exists in a specified snapshot. You can choose whether to include modified write data from the snapshot in the rollback. You must unmount the master volume from the host operating system before using this command. The command will prompt you to ensure the master volume is unmounted before proceeding. Caution – All data that differs between the master volume and the snapshot is lost.
Example Roll back master volume MV1 to snapshot SS1. # rollback master-volume MV1 snapshot SS1 Leaving the master volume mounted when starting a rollback operation will result in data corruption. The master volume must be unmounted prior to beginning the rollback operation. The master volume can be remounted once the rollback has started. Not unmounting the volume prior to beginning the rollback operation will result in data corruption.
scrub vdisk Description For specified RAID 3, 5, 6, and 50 virtual disks, this command verifies all parity blocks. For specified RAID 1 and 10 virtual disks, this command compares the primary and secondary drives. In addition, this command scrubs virtual disk metadata, and stripe and NRAID virtual disks. When the scrub is complete, an event is logged specifying the number of errors found. Input scrub vdisk vdisks Parameter Description vdisks Specifies the virtual disks by name or serial number.
set auto-write-through-trigger Description Sets the trigger conditions that cause the controller to change the cache policy from write-back to write-through. By default, automatic write-back is enabled. Alias: set awt When the cache mode is changed, an event is logged.
Parameter Description partner-notify enable|disable Specify whether to notify the partner controller that a trigger condition occurred. Enable this option to have the partner also change to write-through mode for better data protection. Disable this option to allow the partner continue using its current caching mode for better performance. The default is Disabled. auto-write-back enable|disable Specify whether the cache mode automatically changes to write-back after the trigger condition is cleared.
set awt Alias for set auto-write-through-trigger. See “set auto-write-throughtrigger” on page 107.
set cache-parameters Description Sets cache options for a specific volume, or the cache redundancy mode for a dualcontroller storage system. Note – Only change cache settings if you fully understand how your operating system, application, and HBA move data so that you can adjust the settings accordingly. Be prepared to monitor system performance using the virtual disk statistics and adjust read-ahead size until you find the optimal size for your application.
Cache Optimization Mode Before creating or modifying a volume, determine the appropriate cache optimization mode. The controller supports super-sequential optimization mode for sequential I/O and standard optimization mode for random I/O. The cache optimization mode setting for each volume optimizes the cache block size used by the controller: ■ For sequential optimization, the cache block size is 128 Kbyte. ■ For random optimization, the cache block size is 32 Kbyte.
Independent Cache Performance Mode In the storage system’s default operating mode, Active-Active, data for volumes configured to use write-back cache is automatically mirrored between the two controllers. Cache redundancy has a slight impact on performance but provides fault tolerance. You can disable cache redundancy, which permits independent cache operation for each controller; this is called independent cache performance mode (ICPM).
To set the cache redundancy mode for the storage system: set cache-parameters independent enable|disable Parameter Description volume Specifies the volume by its name or serial number. For the syntax to use, see “Volume Syntax” on page 26. write-policy write-back| write-through Optional. Sets the cache policy to either: • write-back: Write-back caching does not wait for data to be completely written to disk before signaling the host that the write is complete.
Parameter Description read-ahead-size disable|default|maximum| 64KB|128KB|256KB|512KB| 1MB|2MB|4MB|8MB|16MB|32MB Optional. Controls the use and size of readahead cache: • disable: Turns off read-ahead cache. This is useful if the host is triggering read ahead for what are random accesses. This can happen if the host breaks up the random I/O into two smaller reads, triggering read ahead. You can use the volume statistics read histogram to determine what size accesses the host is doing.
Parameter Description independent enable|disable Sets the cache redundancy mode for a dualcontroller storage system. enable sets the storage system’s operation mode to Independent Cache Performance Mode. When this mode is enabled, controller failover is disabled and write-back cache is not mirrored to the partner controller. This results in improved write performance but at a risk of loss of unwritten data if a controller failure occurs while there is data in the controller’s cache memory.
set chap-record Description iSCSI only. Changes the CHAP record for a specific originator. This command is permitted whether or not CHAP is enabled. Input set chap-record name originator-name [secret originator-secret] [mutual-name recipient-name] [mutual-secret recipient-secret] Parameter Description name originatorname Specifies the originator name, which is typically the originator's IQN. The name is case sensitive and can include a maximum of 223 characters. secret originator-secret Optional.

ping Tests communication with a remote host. The remote host is specified by IP address. Ping sends ICMP echo response packets and waits for replies. For details see “ping” on page 97. rescan When installing a system with drive enclosures attached, the enclosure IDs might not agree with the physical cabling order. This is because the controller might have been previously attached to some of the same enclosures and it attempts to preserve the previous enclosure IDs if possible.
Note – If an iSCSI storage system is connected to a Microsoft Windows host, the following event is recorded in the Windows event log: Initiator failed to connect to the target. For details see “restart” on page 101. restore defaults Note – This command should only be used by service technicians, or with the advice of a service technician. Restores the manufacturer's default configuration to the controllers.
set expander-fault-isolation When fault isolation is enabled, the Expander Controller will isolate PHYs that fail to meet certain criteria. When fault isolation is disabled, the errors are noted in the logs but the PHYs are not isolated. Note – This command should be used only by service technicians, or with the advice of a service technician. For details see “set expander-fault-isolation” on page 125. set expander-phy The Expander Controller will enable or disable (isolate) the a specific PHY.
set protocols Enables or disables one or more of the following management services and protocols.
show enclosure-status Shows the status of system enclosures and their components. For each attached enclosure, the command shows general SCSI Enclosure Services (SES) information followed by component-specific information. For details see “show enclosure-status” on page 178. show events Shows events for an enclosure, including events from each Management Controller and each Storage Controller. A separate set of event numbers is maintained for each controller module.
show protocols Shows which management services and protocols are enabled or disabled. For details see “show protocols” on page 207. show redundancy-mode Shows the redundancy status of the system. For details see “show redundancy-mode” on page 208. trust Enables an offline virtual disk to be brought online for emergency data collection only. It must be enabled before each use. Caution – This command can cause unstable operation and data loss if used improperly. It is intended for disaster recovery only.
Problems Scheduling Tasks There are two parts to scheduling tasks: you must create the task and then create the schedule to run the task. Create the Task There are three tasks you can create: TakeSnapshot, ResetSnapshot, and VolumeCopy. Perform the operation directly to ensure the command syntax is correct. For example, if you want to schedule taking a snapshot, first issue a command to take the snapshot and verify that it runs. Then create a task that will take the snapshot when scheduled.
Errors Associated with Scheduling Tasks The following table describes error messages associated with scheduling tasks. Table 4-1 Errors Associated with Scheduling Tasks Error Message Solution Task Already Exists Select a different name for the task. Unknown Task Type The task type is misspelled. Valid task types are: TakeSnapshot, ResetSnapshot and VolumeCopy. Schedule Already Exists Select a different name for the schedule.
Glossary The glossary defines terms and acronyms used in MSA2000 Family storage system documentation. Definitions obtained from the Storage Networking Industry Association (SNIA) Dictionary are indicated with “(SNIA)” at the end. For the complete SNIA Dictionary, go to www.snia.org/education/dictionary. active-active Synonym for dual active components or controllers.
cache The location in which data is stored temporarily. There are a variety of cache types. Read cache holds data in anticipation that it will be requested. Write cache holds data written by a client until it can be stored on other (typically slower) storage media such as disk or tape. (SNIA) See also write-back cache, write-through cache.
controller enclosure controller module copy-on-write (COW) An enclosure that contains disk drives and one or two controller modules. See controller module. A FRU that contains: a Storage Controller processor; a Management Controller processor; a SAS expander and Expander Controller processor; management interfaces; a LAN subsystem; cache protected by a capacitor pack and Compact Flash memory; host, expansion, management, and service ports; and midplane connectivity.
data mirroring Data written to one disk drive is simultaneously written to another disk drive. If one disk fails, the other disk can be used to run the virtual disk and reconstruct the failed disk. The primary advantage of disk mirroring is 100 percent data redundancy: since the disk is mirrored, it does not matter if one of the disks fails; both disks contain the same data at all times and either can act as the operational disk.
enclosure management processor (EMP) Ethernet adapter Expander Controller (EC) expansion module fabric fabric switch An Expander Controller subsystem that provides data about an enclosure’s environmental conditions such as temperature, power supply and fan status, and the presence or absence of disk drives. An adapter that connects an intelligent device to an Ethernet network. Usually called an Ethernet network interface card, or Ethernet NIC.
fault-tolerant virtual disk FC FC-AL Fibre Channel (FC) Fibre ChannelArbitrated Loop (FC-AL) field-replaceable unit (FRU) FRU 266 A virtual disk that provides protection of data in the event of a single disk drive failure by employing RAID 1, 3, 5, 6, 10, or 50. RAID 6 also provides protection against the failure of two drives. See Fibre Channel (FC). See Fibre Channel-Arbitrated Loop (FC-AL).
host bus adapter (HBA) host port host port interconnect hot swap in-band management An adapter that connects a host I/O bus to a computer’s memory system. Host bus adapter is the preferred term in SCSI contexts. Adapter and NIC are the preferred terms in Fibre Channel contexts. The term NIC is used in networking contexts such as Ethernet and token ring. (SNIA) A host-interface port on a controller module or an expansion module.

In an iSCSI network, a frame that can contain 9000 bytes for large data transfers. A normal frame can contain 1500 bytes. Kilobyte.
management host management information base (MIB) master volume Mbyte MC metadata MIB network interface card (NIC) Network Time Protocol (NTP) NIC node WWN Non-RAID NTP originator A workstation with direct or network connections to a storage system’s management ports and that is used to manage the system. A database of managed objects accessed by network management protocols.
out-of-band management ownership PHY PID point-to-point port bypass circuit (PBC) port WWN power-and-cooling module In an active-active configuration, one controller has ownership of the following resources: virtual disks and vdisk spares. When a controller fails, the other controller assumes temporary ownership of its resources. Hardware component that converts between digital and analog in the signal path between the Storage Controller, Expander Controller, disk drives, and SAS ports.
RAS Reliability, availability, and serviceability. These headings refer to a variety of features and initiatives all designed to maximize equipment uptime and mean time between failures, minimize downtime and the length of time necessary to repair failures, and eliminate or decrease single points of failure in favor of redundancy.
SCSI Enclosure Services (SES) An ANSI X3T10 standard for management of environmental factors such as temperature, power, voltage, etc. (SNIA) In MSA2000 Family storage systems, SES data is managed by the Expander Controller and EMP. secret SFP Small form-factor pluggable connector, used in FC controller module host ports. An SFP is a FRU. SID Secondary controller identifier number. SMART Self-Monitoring Analysis and Reporting Technology.
standard volume standby state Storage Area Network (SAN) Storage Controller (SC) storage system A volume that is not enabled for snapshots. See spare. The current operational status of a disk drive, a virtual disk, or controller. A controller module stores the states of drives, virtual disks, and the controller in its nonvolatile memory. This information is retained across power interruptions.
ULP UT Universal Time. A modern time system related to the conventional Greenwich Mean Time (GMT) used for time zones. UPS Uninterruptible Power Supply. vdisk Abbreviation for virtual disk. vdisk spare A disk drive that is marked as a spare to support automatic data rebuilding after a disk drive associated with a virtual disk fails.
world wide name (WWN) A unique 64-bit number assigned by a recognized naming authority (often via block assignment to a manufacturer) that identifies a node process or node port. (SNIA) MSA2000 Family storage systems derive WWNs from the serial numbers of controller modules and expansion modules. world wide node name (WWNN) world wide port name (WWPN) write policy write-back cache A globally unique 64-bit identifier assigned to each Fibre Channel node process.
