About this guide This guide provides information about managing an HP StorageWorks 2000 G2 Modular Smart Array storage system by using its command-line interface (CLI). Intended audience This guide is intended for storage system administrators.
CAUTION: NOTE: Indicates that failure to follow directions could result in damage to equipment or data. Provides additional information. HP technical support Telephone numbers for worldwide technical support are listed on the HP support web site: http://www.hp.com/support/.
1 Using the CLI This chapter introduces the HP StorageWorks 2000 G2 Modular Smart Array command-line interface (CLI). Accessing the CLI The CLI software embedded in controller modules enables you to manage a storage system out of band. You can access the CLI in two ways: • By using Telnet, an SSH application, or a terminal emulator on a management host that is remotely connected through a LAN to a controller module’s network port.
Using CLI interactively 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. 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 above 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. After the user has been logged in, other commands can be sent to the CLI. For scripting support, change the CLI output mode from the default, console, which produces human-readable output, to API, which produces XML output.
Table 3 Element XML API elements (continued) Description and attributes PROPERTY A PROPERTY element provides detail about the attributes of an OBJECT. A property has these attributes: • name. The unique name for the property within the object. • type. The type of data represented by the element data. • size. Typically the maximum size of the output. Usually only important if the console output is displayed in rows. • draw. Whether to show or hide this data in console format. • sort.
The recommended command to enable XML API mode is set cli-parameters api pager off, which displays output without pausing after each screenful of data. The following example shows how output of the show volumes command appears in XML API mode: # show volumes
0 The following example shows XML API output from the create vdisk command: # create vdisk vd-1 disks 2.6,2.7,2.8 level r5
XML API basetypes The following basetypes can be used when calling the meta command to obtain complete metadata for all CLI objects.
In the following example, embedded objects contain media-specific detail for ports, and only name and key properties are shown:
Command syntax Keywords and parameters Command keywords must be entered in lowercase. Parameter values can be entered in uppercase and lowercase. Unless otherwise specified, a parameter value can include any valid UTF-8 characters except backslash (\), comma, double quote ("), and control characters. A parameter value that includes a space must be enclosed in double quotes. Parameters such as names of users and volumes have a maximum length in bytes.
Command completion, editing, and history The CLI supports command completion, command editing, and command history. When entering commands interactively you can abbreviate their names and keywords. For example, you can enter sho cl to run the show cli-parameters command. If you enter too few letters to uniquely identify a keyword, pressing Tab will list commands or keywords that match the entered string and redisplays the string so you can complete it.
To view the information shown in this topic and in Command completion, editing, and history above, enter: help help Size representations Operating systems usually show volume size in base 2. Disk drives usually show size in base 10. Memory size is always shown in base 2. In the CLI, the base for entry and display of storage-space sizes can be set per user or per session; see create user and set cli-parameters. When entering storage-spaces sizes only, either base-2 or base-10 units can be specified.
Using the CLI
2 Categorical list of commands This chapter helps you find a command within a category of functionally related commands. A command might appear in more than one category.

3 Alphabetical list of commands This chapter is organized to help you find a command by name.
abort scrub Description Aborts the scrub vdisk operation for specified vdisks. Syntax abort scrub vdisk vdisks Parameters vdisks Names or serial numbers of the vdisks to stop scrubbing.
abort verify Description Aborts the verify vdisk operation for specified vdisks. Syntax abort verify vdisk vdisks Parameters vdisks Names or serial numbers of the vdisks to stop verifying.
abort volumecopy Description Aborts copying a volume. When the abort is complete, the destination volume is deleted. Syntax abort volumecopy volume Parameters volume Name or serial number of the source or destination volume. Example Abort creating destination volume vd1_copy: # abort volumecopy v1_copy Success: Command completed successfully. - The volume copy was aborted.
clear cache Description Clears unwritable cache data from both controllers. This data cannot be written to disk because it is associated with a volume that no longer exists or whose disks are not online. If the data is needed, the volume's disks must be brought online. If the data is not needed it can be cleared, in which case it will be lost and data will differ between the host and disk. Unwritable cache is also called orphan data.
clear disk-metadata Description Clears metadata from “leftover” disks. Each disk contains metadata that the system uses to identify the disk's owning vdisk, if any. If the system cannot locate the vdisk, as when the disk has been moved to a different system, the owning vdisk is shown as Leftover. A leftover disk’s Fault/UID LED is illuminated amber. You must clear the metadata before you can use the disk in a different vdisk or as a spare.
clear events Description For use by or with direction from a service technician. Clears the event log for controller A, B, or both. Syntax clear events [a|b|both] Parameters a|b|both Optional. The controller event log to clear. If this parameter is omitted, both event logs are cleared. Example Clear the event log for controller A: # clear events a Success: Command completed successfully. - Controller A event log was successfully cleared.
clear expander-status Description For use by or with direction from a service technician. Clears the counters and status for SAS expander lanes. 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. NOTE: If a rescan is in progress, the clear operation will fail with an error message saying that an EMP does exist. Wait for the rescan to complete and then retry the clear operation.
convert master-to-std Description Converts a specified master volume into a standard volume; that is, it disables the volume from accepting snapshots. If the specified volume has associated snapshots, you must delete the snapshots before converting the volume. Syntax convert master-to-std master-volume Parameters master-volume Name or serial number of the master volume to convert. For syntax, see Command syntax.
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 in different vdisks. Syntax convert std-to-master snap-pool snap-pool standard-volume Parameters snap-pool snap-pool Name or serial number of the snap pool to associate with the new master volume. For syntax, see Command syntax.
create chap-record Description For iSCSI, creates a CHAP record to authenticate login requests. When CHAP is enabled, the record enables authentication between the originator (initiator) and recipient (target) of a login request. 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).
create host Description Creates a host entry with an associated nickname. When mapping volumes to hosts the nickname can make a host easy to recognize. Syntax create host id ID nickname [profile standard|openvms|hp-ux] Parameters id ID For FC and SAS, the host node's 16-hex-digit WWPN. For iSCSI, the initiator's IQN. A host ID cannot have more than one entry in the system. nickname A nickname for the host node.
create master-volume Description Creates a volume that is enabled for snapshots. The master volume is created in a specified vdisk and is associated with a specified snap pool. The vdisk and snap pool must be owned by the same controller. Syntax create master-volume vdisk vdisk size size[B|KB|MB|GB|TB|KiB|MiB|GiB|TiB] snap-pool snap-pool [lun LUN] [ovms-uid ID] name Parameters vdisk vdisk Name or serial number of the vdisk to create the volume in. For syntax, see Command syntax.
create schedule Description Schedules a task to run automatically. Syntax create schedule schedule-specification "specification" task-name task-name schedule-name Parameters schedule-specification "specification" Defines when the task will first run, and optionally when it will recur and expire. You can use a comma to separate optional conditions. Dates cannot be in the past. • start mm/dd/yyyy hh:mm [AM|PM] If neither AM nor PM is specified, a 24-hour clock is used.
create snap-pool Description Creates a snap pool to use for snapshot data. A snap pool is an internal volume and cannot be mapped. Syntax create snap-pool vdisk vdisk size size[B|KB|MB|GB|TB|KiB|MiB|GiB|TiB] name Parameters vdisk vdisk Name or serial number of the vdisk to create the snap pool in. For syntax, see Command syntax. size size[B|KB|MB|GB|TB|KiB|MiB|GiB|TiB] Sets the volume size using the current base, as shown by show cli-parameters.
create snapshots Description Creates a snapshot of each specified source volume. The source volume can be a standard volume or a master volume. The first time a snapshot is created of a standard volume, the volume is converted to a master volume and a snap pool is created. The snap pool's size is 20% of the volume size or 10 GB, whichever is larger. Before creating or scheduling snapshots, verify that the vdisk has enough free space to contain the snap pool.
create task Description Creates a task that can be scheduled. You can create a task to take a snapshot of a master volume, to copy a snapshot or a master volume to a new standard volume, or to reset a snapshot. CAUTION: Before scheduling a reset snapshot task, consider that if the snapshot is mounted to a host operating system, the snapshot must be unmounted before the reset is performed; leaving it mounted can cause data corruption.
dest-prefix prefix Optional. A label to identify the volume copy created by this task. Copy names have the format prefix_c001 through prefix_c1023. modified-snapshot yes|no Optional. Specifies whether to include or exclude modified write data from the snapshot in the copy. This parameter applies only when the source volume is a snapshot; it is ignored if the source volume is a master volume. • yes: Include modified snapshot data. • no: Exclude modified snapshot data.
create user Description Creates a user profile. The system supports 12 user profiles.
storage-size-units auto|MB|GB|TB Optional. Alias for units. temperature-scale celsius|c|fahrenheit|f Optional. Specifies to use the Celsius scale or Fahrenheit scale for temperature values.

Suppresses the confirmation prompt that requires a yes or no response. name The user to delete. Names are case sensitive. Example Delete user jsmith: # delete user jsmith Are you sure you want to delete user jsmith? yes Success: Command completed successfully. - The user was deleted.
delete vdisk Description Deletes specified vdisks. This disassociates all disks that are assigned to the vdisks, and unmaps the vdisks' volumes. CAUTION: Deleting a vdisk will delete all data on that vdisk. NOTE: You cannot delete a vdisk if it contains a snap pool that is associated with a master volume on another vdisk. Syntax delete vdisk [prompt yes|no] vdisks Parameters prompt yes|no Optional.
delete volume Description Deletes specified volumes. CAUTION: Deleting a volume will delete all data in that volume. Syntax delete volume volumes Parameters volumes Names or serial numbers of the standard, master, snap-pool, or snapshot volumes to delete. For syntax, see Command syntax.

dequarantine Description A previously fault-tolerant vdisk becomes quarantined when not all of its disks are detected after a restart or power cycle.
exit Description Log off and exit the CLI session.
expand master-volume See expand volume.
expand snap-pool Description Expands a snap pool. Expansion is restricted to the space available on the vdisk containing the snap pool. If insufficient space is available for expansion on the vdisk, first expand the vdisk by using expand vdisk.
expand vdisk Description Adds disks to a vdisk. The expansion capability for each supported RAID level is: RAID level Expansion capability Maximum disks NRAID Cannot expand. 1 0, 3, 5, 6 Can add 1–4 disks at a time. 16 1 Cannot expand. 2 10 Can add 2 or 4 disks at a time. 16 50 Can expand the vdisk one RAID-5 sub-vdisk at a time. The added RAID-5 sub-vdisk must contain the same number of disks as each original sub-vdisk.
expand volume Description Expands a standard or master volume. Expansion is restricted to the space available on the vdisk containing the volume. If insufficient space is available for expansion on the vdisk, first expand the vdisk by using expand vdisk. To expand a master volume: 1. Delete all of its snapshots by using delete all-snapshots. 2. Convert it to a standard volume by using convert master-to-std. 3. Expand the standard volume by using expand volume. 4.
map volume Description Maps a volume using settings that override the volume's default mapping. When a volume is created, if no mapping settings are specified the volume is not mapped; otherwise, those settings become its default mapping, which 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. The default mapping's LUN is known as the volume's default LUN.

meta Description For API use, shows all property metadata for objects. This includes data not shown in brief mode. The data is static and never changes. Syntax meta basetypes Parameters basetypes A basetype or a list of basetypes separated by commas (with no spaces) to specify the objects to show metadata for. Basetypes are listed in XML API basetypes.
ping Description Tests communication with a remote host. The remote host is specified by IP address. Ping sends ICMP echo response packets and waits for replies. Syntax ping host-address [count] Parameters host-address The remote host's IP address in dotted decimal form. count Optional. The number of packets to send. The default is 4 packets. Use a small count because the command cannot be interrupted. Example Send two packets to the remote computer at 10.134.50.6: # ping 10.134.50.6 2 Info: Pinging 10.134.
rescan Description This command forces rediscovery of attached disks and enclosures. If both Storage Controllers are online this command also reassigns enclosure IDs 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 disks are inserted or removed; the controllers do this automatically.
reset host-link Description Resets specified FC or SAS controller host ports (channels). For an FC host port configured to use FC-AL (loop) topology, a loop initialization primitive (LIP) is issued. For a SAS host port, a COMINIT/COMRESET sequence is issued. Syntax reset host-link ports ports Parameters port ports A controller host port ID, a comma-separated list of IDs, a hyphenated range of IDs, or a combination of these. A port ID is a controller ID and port number, and is not case sensitive.
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 a controller module. 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 Controller is not restarted so it can provide status information to external interfaces.
restore defaults Description For use by or with direction from 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.
scrub vdisk Description Analyzes specified vdisks to detect, report, and store information about disk defects. Vdisk-level errors reported include: hard errors, medium errors, and bad block replacements (BBRs). Disk-level errors reported include: metadata read errors, SMART events during scrub, bad blocks during scrub, and new disk defects during scrub. For RAID 3, 5, 6, and 50, scrub checks all parity blocks to find data-parity mismatches.
set advanced-settings Description For API use, sets advanced system configuration options.
partner-firmware-upgrade enabled|disabled|on|off Optional. Sets whether component firmware versions are monitored and will be automatically upgraded on the partner controller. partner-notify enabled|disabled|on|off Optional. Sets 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.
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. You can set multiple triggers. By default super-cap-failure and auto-write-back are enabled. Alias: set awt. When the cache mode is changed, an event is logged.
set cache-parameters Description Sets a volume's cache options or the system's cache redundancy mode. Settings you can change include: • Cache write policy • Cache optimization mode • Cache read-ahead size • Cache redundancy mode NOTE: Only change the read-ahead cache settings if you fully understand how the host operating system, application, and adapter move data so that you can adjust the settings accordingly.
Example Set the cache policy and cache optimization mode for volume V1: # set cache-parameters optimization super-sequential read-ahead-size maximum V1 Success: Command completed successfully. - Cache parameters were changed See also • show cache-parameters • show volumes Cache write policy The cache policy setting for each volume determines when cached data is written to the disks.
Cache redundancy 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. The operating mode applies per storage system, not per volume.
set chap-record Description For iSCSI, changes an originator's CHAP record. This command is permitted whether or not CHAP is enabled. Syntax set chap-record name originator-name [secret originator-secret] [mutual-name recipient-name mutual-secret recipient-secret] Parameters name originator-name The originator name; typically the originator's IQN. secret originator-secret The secret that the recipient uses to authenticate the originator. The secret is case sensitive and can include 12–16 bytes.
set cli-parameters Description Sets options that control CLI behavior. If you are accessing the CLI through the network port, settings apply to the current CLI session only. If you are accessing the CLI through the enclosure's CLI port, settings persist across sessions. The base, locale, precision, temperature scale, timeout, and units settings are read from the user's profile, and can be overridden by using this command.
precision # Optional. Sets the number of decimal places (1–10) for display of storage-space sizes. storage-size-base 2|10 Optional. Alias for base. storage-size-precision # Optional. Alias for precision. storage-size-units auto|MB|GB|TB Optional. Alias for units. temperature-scale celsius|c|fahrenheit|f Optional. Specifies to show temperatures in degrees Fahrenheit or Celsius. timeout # Optional. Sets the timeout value in seconds for the login session.
Set CLI to show output in console mode: # set cli-parameters console Success: Command completed successfully. - The settings were changed successfully.
set controller-date Description Sets the date and time for each Management Controller and then updates the date and time for each Storage Controller. Syntax set controller-date jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec day hh:mm:ss year time-zone [ntp enabled|disabled|on|off] [ntpaddress IP-address] Parameters jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec The month. day The day number (1–31). hh:mm:ss The hour on a 24-hour clock (0–23), the minutes (0–59), and the seconds (0–59).
set debug-log-parameters Description For use by or with direction from a service technician. Sets the types of debug messages to include in the Storage Controller debug log. If multiple types are specified, use spaces to separate them and enclose the list in double quotes. Syntax set debug-log-parameters message-type+|- [...
set disk-parameters Description Selects a global disk Self-Monitoring Analysis and Reporting Technology (SMART) setting. Disks equipped with this technology can alert the controller of impending disk failures. Changes to the SMART setting take effect after a rescan or a controller restart. Syntax set disk-parameters smart enabled|disabled|on|off|detect-only Parameters smart enabled|disabled|on|off|detect-only Enables or disables SMART monitoring for all disks in the storage system.
