Disk pool capacity - full

All of the disk pool's reserved capacity and free capacity has been used. If more drives fail in this disk pool, the volumes in the disk pool will be degraded and you will likely lose data. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.

CAUTION:
Risk of Data Loss. This problem needs to be resolved immediately. Data loss may occur if another drive fails before you follow these recovery steps.
Important:
  • Since the disk pool has no free capacity, if another drive failure occurs there will be no capacity to use for a reconstruction operation.

  • This problem typically occurs when the disk pool's free capacity has been consumed during reconstruction operations due to other drive failures.

  • When the disk pool has no free capacity, the following occurs:

    • No new volumes can be created.

    • Existing volumes cannot be expanded.

    • Failed drives cannot be reconstructed.

  • You can resolve this problem in three ways (or through a combination of these three):

    • Replace any failed drives (recommended). You should replace enough failed drives to have sufficient reserved capacity to reconstruct drives when drive failures occur. To do this, it is recommended that the minimum amount of drives to be replaced should match the Required reserve drive count (identified in the Details area).

    • Add drives to expand the capacity of the disk pool.

    • Delete any unneeded volumes in the disk pool to free up capacity.

Recovery Steps

  1. Perform one of the following steps:

    If... Then...
    You want to replace the failed drives (recommended) Select the failed drive procedure from the Recovery Guru Summary area and use the associated recovery steps to fix the failed drive. Repeat the recovery steps for all of the drives you want to replace.
    You want to expand the usable capacity of the disk pool by adding drives Perform the following steps:
    1. On the Storage and Copy Services tab in the Array Management Window, highlight the affected disk pool.

    2. Select the Storage > Disk Pool > Add Drives (Capacity) menu option.

    3. Select one or more unassigned drives to add to the disk pool.

      Note: It is important to have enough reserved capacity to reconstruct data when drive failures occur. It is recommended to add as many drives as needed to reach the Required reserve drive count (identified in the Details area).
    4. Click the Add button.

    5. Go to step 2.

    You want to lower the preservation capacity (reserved drive count) Perform the following steps:
    1. On the Storage and Copy Services tab in the Array Management Window, highlight the affected disk pool.

    2. Select the Storage > Disk Pool > Change > Settings menu option.

    3. Decrease the number of drives dedicated to preservation capacity.

    4. Click the OK button.

    5. Go to step 2.

  2. Click the Recheck button to rerun the Recovery Guru. The failure should no longer appear in the Summary area. If the failure appears again, contact your Technical Support Representative.
