Volume group or pool missing

The storage array has detected that all of the drives associated with a volume group or pool are missing.

This problem occurs for the following reasons:

  • The drives associated with the affected volume group or pool were bypassed by the storage array.

  • The drives associated with the affected volume group or pool were physically removed.

  • A loss of power occurred to one or more drive shelves.

Important
Volume data is not accessible for the volume group or pool because there are no drives remaining.
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 Drive Bypassed problems being reported in the Problems area for any of the drives shown in the Details area?

    • If yes, select the Drive Bypassed problem from the Problems area and use the associated recovery steps to correct the bypassed drives. If this problem is still displayed after fixing all of the Drive Bypassed problems, go to step 2.

    • If no, go to step 2.

  2. Have the affected drives been physically removed from the storage array?

    • If yes, go to step 3.

    • If no, go to step 10.

  3. Why were the drives removed?

    • If the drives were removed inadvertently, go to step 4.

    • If the drives were removed to import the volume group or pool to another storage array, go to step 5.

    • If the drives were removed to add capacity to another storage array, go to step 9.

  4. Re-insert the drives back into the drive shelf waiting at least 30 seconds after inserting each drive. The fault indicator light might be lit for a short time (one minute or less). Once all of the drives are displayed in the Hardware page, go to step 14.

  5. Were the drives associated with a volume group or pool?

    • If the drives were associated with a volume group, go to step 6.

    • If the drives were associated with a pool, the import feature does not support importing pools to another storage array. Re-insert the drives back into the drive shelf waiting at least 30 seconds after inserting each drive. The fault indicator light might be lit for a short time (one minute or less). Then, contact your Technical Support Engineer to determine the best way to move the pool's data to another storage array.

  6. Select the Save icon in the Recovery Guru to save the remaining steps to a file. These steps will no longer be available after you complete step 7.

  7. Export the affected volume group from this storage array.

    1. Re-insert the drives back into the drive shelf waiting at least 30 seconds after inserting each drive. The fault indicator light might be lit for a short time (one minute or less).

    2. Wait until all of the drives are displayed in the Hardware page.

    3. 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.

  8. Import the affected volume group to the new storage array, and then go to step 14.

    1. Remove the affected drives from this storage array and insert them into the new storage array's drive shelf waiting at least 30 seconds after inserting each drive. The fault indicator light might be lit for a short time (one minute or less).

    2. Wait until all of the drives are displayed in the new storage array's Hardware page.

    3. From a command prompt run the start volumeGroup import command.

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

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

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

    4. Go to step 14.

  9. Delete the affected volume group or pool shown in the Details area.

    1. Go to Storage > Pools and Volumes Groups.

    2. Highlight the volume group or pool shown in the Details area.

    3. Select Delete under Uncommon Tasks.

    4. Go to step 14.

  10. Does the drive shelf containing the associated pool or volume group have power?

    • If yes, contact your Technical Support Engineer.

    • If no, go to step 11.

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

    • If yes, go to step 12.

    • If no, correct the problem and go to step 14.

  12. Are the power switches on the shelf's power supplies in the on position?

    • If yes, go to step 13.

    • If no, correct the problem and go to step 14.

  13. 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.

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