Managing pools

You can get information about pools, get detailed information about specific pools, change pool settings, or delete pools.

Modifying pool settings

You can modify the pool name and the threshold value set for the pool usage rate.

For storage systems, you can set the subscription limit for the pool that you are modifying. The subscription limit is the ratio of the total volume capacity (including the snapshot capacity) to the total pool capacity expressed as a percentage (%).

If the usage exceed the depletion threshold set on the pool which is used to store differential-data snapshots, all of the snapshots may become unusable.

Note

You can use the Embedded CCI to change the details of a tiered pool, using the command raidcom modify pool. Details include free space for a new allocation, the tier buffer rate, monitoring mode, and active flash enablement or disablement.

Some details must be changed using Device Manager - Storage Navigator.

You can also use the Embedded CCI to shrink a pool, using the command raidcom delete pool.

Procedure

  1. In the navigation bar, click Pools.

  2. Click GUID-AD1968EB-1936-404B-BECF-E261384BB0BD-low.gif (Edit Pool) for the pool you are editing.

  3. Modify the settings.

  4. Click the pool name to open the details page, and then confirm that the settings are correct.

Deleting pools

You can delete pools that are no longer used. Make sure no volumes have been created for the pool being deleted.

  1. In the navigation bar, click Pools.

  2. Select one or more pools and click GUID-F074FA1A-3F5C-4AD5-A29C-48E36520F7C7-low.gif (Delete Pools).

    Specifies the Pool ID (0-127) or pool name for Copy-on-Write Snapshot, Dynamic Provisioning, Dynamic Provisioning for Mainframe, Dynamic Tiering, active flash, Dynamic Tiering for Mainframe, or active flash for mainframe.

    When only a number is specified, it is recognized as a pool ID. Therefore, to specify a pool whose name is a number, use the pool ID instead of the pool name.

  • -status <status>

    Supported storage systems:

    • VSP G200, G400, G600, G800 and VSP F400, F600, F800
    • VSP
    • HUS VM

    Specifies the status of the pool. To restore the pool status, specify "nml".

  • -status {nml|stop_shrinking}

    Supported storage systems:

    • VSP 5000 series
    • VSP G130, G/F350, G/F370, G/F700, G/F900

    Specifies the status of the pool:

    • nml: Pool status is restored.
    • stop_shrinking: Stops shrinking the pool.
  • -user_threshold <threshold_1> [<threshold_2>]

    Sets a user-defined threshold.

    • For Dynamic Provisioning, Dynamic Provisioning for Mainframe, Dynamic Tiering, active flash, Dynamic Tiering for Mainframe, and active flash for mainframe, you may specify two user-defined thresholds, and their valid ranges are 1-100%, respectively. If you specify <threshold_1> and <threshold_2>:

      the value of <threshold_1> is set as the threshold for WARNING specified to a pool.

      the value of <threshold_2> is set as the threshold for High water mark specified to a pool.

      If you specify only <threshold_1>, your specified value and the system default value (80%) are applied.

      The setting in which you specify only <threshold_1> is supported to maintain backward compatibility with microcode before 70-02-0x-xx/xx. Once you specify two user-defined thresholds, you must continue to specify two user-defined thresholds thereafter.

    • The valid range for Thin Image or Copy-on-Write Snapshot is 20-95%. You may specify only <threshold_1>. Even if you specify the value for <threshold_2>, the value is ignored.

    • non_realtime_tiering: Disables active flash.
  • -blocking_mode <IO blocking mode>

    Sets the I/O activity (availability for read/write access) when the pool for Dynamic Provisioning, Dynamic Tiering, or active flash is full and when the pool for Dynamic Provisioning, Dynamic Tiering, or active flash is blocked. This option is ignored when the microcode version does not support the option.

    NoteIf the microcode version does not support this option, "-" is displayed in the BM column when you execute the raidcom get dp_pool command.
    • pool_full: If the pool is full, read/write access for the target DP-VOL is disabled. If the pool is blocked, read/write access for the target DP-VOL is enabled.
    • pool_vol_blockade: If the pool-VOL is blocked, read/write access for the target DP-VOL is disabled. If the pool-VOL is full, read/write access for the target DP-VOL is enabled.
    • full_or_blockade: If the pool is full or blocked, read/write access for the target DP-VOL is disabled.
    • no_blocking: If the pool is full and/or blocked, read/write access for the target DP-VOL is enabled.
  • -data_direct_mapping {enable| disable}

    For VSP 5000 series, VSP G1x00, VSP F1500, : Changes the setting of the data direct mapping attribute of the pool for Dynamic Provisioning.

    • enable: Changes a pool for Dynamic Provisioning to a pool for Dynamic Provisioning that has the data direct mapping attribute.
    • disable: Changes a pool for Dynamic Provisioning that has the data direct mapping attribute to a pool for Dynamic Provisioning.
  • -deduplication yes -ldev_id <ldev#> … [-ssids <ssid> …]

    For VSP 5000 series,VSP G/F350, G/F370, G/F700, G/F900, an error occurs if you specify this option.

    If you want to assign an SSID to the deduplication system data volume to be created, specify “-ssids <ssid> …” in hexadecimal. SSIDs specified by “-ssids <ssid> …” are assigned to deduplication system data volumes specified for “-ldev_id <ldev#> …” in the order they were specified. If you omit this option, or specify auto for <ssid>, SSIDs are assigned automatically to the corresponding deduplication system data volumes.

    If you specify multiple LDEVs, an error occurs because the current microcode does not support this function. If this happens, deduplication of the pool is not enabled.

  • -deduplication no

    Disables deduplication of the pool. When this option is specified, a deduplication system data volume in this pool is deleted.

    For VSP 5000 series,VSP G/F350, G/F370, G/F700, G/F900, an error occurs if you specify this option.
