Volume group or pool incomplete

One or more drives are missing from the storage array resulting in a volume group or pool not having enough drives to service I/O.

This problem occurs for the following reasons:

  • The affected drives were bypassed.

  • The affected volume group was imported from another storage array using the force import operation before all of the volume group's drives were inserted into the storage array.

  • The affected drives were inadvertently removed from the storage array.

  • The affected drives were intentionally removed to replace the drives with new drives.

  • The affected drives were intentionally removed from the storage array to export the associated volume group to another storage array without first preparing the drives for export with the volume group export operation.

  • One or more of the storage array's drive shelves has lost power.

Important

  • Data on the affected volumes is not accessible because there are not enough drives remaining to reconstruct the data from the missing drives.

  • Reinserting some of the missing drives may cause the volume group's or pool's status to transition to partially complete allowing the affected volumes' data to be accessible.

CAUTION
Electrostatic discharge can damage sensitive components

Always use proper anti-static protection when handling components. Touching components without using a grounding wrist strap may damage the equipment.

Recovery Steps​

  1. Are any Bypassed Drive problems being reported in the Problems area for the drives shown in the Details area?

    • If yes, fix the bypassed drives using the recovery steps in the Bypassed Drive procedure listed in the Problems area. This should resolve this problem as well.

    • If no, go to step 2.

  2. Did you just import the affected volume group from another storage array?

    • If yes, go to step 3.

    • If no, go to step 6.

  3. Are the affected drives physically present in the storage array?

    • If yes, go to step 4.

    • If no, go to step 5.

  4. The missing drives were not imported with the rest of the drives. Contact your Technical Support Engineer.

  5. Insert all of the missing drives associated with the affected volume group from the original storage array, and wait for the volume group and all associated volumes to become optimal. Then, go to step 15.

  6. Have the drives shown in the Details area been removed?

    • If yes, go to step 7.

    • If no, go to step 11.

  7. Determine why the drives were removed, and then perform the following action.

    • If the drives were accidentally removed or were removed to replace the drives with new drives, reinsert the original removed drives, and then go to step 15. The fault indicator lights may be lit for a short time (one minute or less).

    • If the drives were removed to export the associated pool to another storage array, reinsert the removed drives, and then go to step 15. Pools cannot be exported to other storage arrays.

    • If the drives were removed to export the associated volume group to another storage array, go to step 8.

  8. Select the Save icon in the Recovery Guru to save the remaining steps to a file. These steps will no longer be accessible after you complete step 9.

  9. Reinsert all of the missing drives into their original slots and wait for the volume group and its associated volumes to become optimal.

  10. Export the volume group. Then, go to step 15.

    1. From a command prompt run the start volumeGroup export command to prepare the volume group's drives for export.

      Command Prompt example: (exact syntax will be dependent on your operating system)

      SMcli (hostname or IP address) -c "start volumeGroup [volumeGroupName] export ;"

      Help with E-Series CLI commands is available from the online Document Center or by contacting Technical Support.

    2. Go to step 15.

  11. Does the drive shelf containing the affected drives have power?

    • If yes, contact your Technical Support Engineer.

    • If no, go to step 12.

  12. Are the drive shelf's power supplies connected to an operating power source?

    • If yes, go to step 13.

    • If no, correct the problem and go to step 15.

  13. Are the power switches on the shelve's power supplies in the on position?

    • If yes, go to step 14.

    • If no, correct the problem and go to step 15.

  14. Are any power supply related problems being reported in the Problems area for power supplies in the drive shelf?

    • If yes, correct the problem using the recovery steps in the associated procedure listed in the Problems area.

    • If no, contact your Technical Support Engineer.

  15. Select Recheck to ensure the problem has been resolved.
