Multiple Disk Groups Refer to Foreign Physical Disk (Scenario 2)

What Caused the Problem?

A Partially Complete disk group considers a foreign physical disk to be a member of the disk group; however, the physical disk is a member of a foreign disk group (a virtual disk group that is in a Contingent or Exported state). A foreign physical disk is a physical disk that has been exported from this storage array or not yet completely imported into the storage array. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.

Caution: Electronic discharge can damage sensitive components. Always use proper antistatic protection when handling components. Touching components without using a proper ground may damage the equipment.

Important Notes

This problem usually results because ALL of the following are true:
- You inserted one or more physical disks (from a different storage array into this storage array)
- Those foreign physical disks are members of a disk group
- That disk group contains a physical disk that was previously a member of the native Partially Complete Disk Group
- The physical disk that is shared between the two disk groups may or may not be physically inserted in the storage array, rather the two disk groups could be sharing a reference to the same absent physical disk
To resolve this problem, you will need to remove all of the physical disks in the foreign disk group (including the physical disk reporting the problem), reassign a physical disk to take over for the missing physical disk in the Partially Complete Disk Group, and then re-insert the foreign disk group.
You can remove the physical disk while the storage array is receiving I/O.

Recovery Steps

Refer to the Details area to find which physical disks are in the foreign disk group.

Remove all of the physical disks in the foreign disk group including the physical disk that is reporting the problem.

Important: Read all of the following steps thoroughly or click the Save As button before taking action, because you will lose access to these Recovery Steps if you click Recheck.

a	Select the "Partially Complete Disk Group" problem in the Summary area.
b	Complete the Recovery Steps for this problem to transition the disk group to an Optimal state. Note: Choose the option in the Recovery Steps that explains how to replace the missing physical disk using the Replace Physical Disks dialog.
c	After the Disk Group transitions to Optimal, go to step 4.

Note: By replacing the missing physical disk, you have removed the reference from this disk group to the physical disk in the other disk group.

Re-insert each physical disk that you removed in step 2 until all have been re-inserted into the storage array.

When all of the physical disks are spun up and recognized, a Contingent disk group should appear in the Logical view.

Select the Contingent disk group in the Logical View, and then select the Advanced >> Maintenance >> Import Disk Group menu option.

Follow the instructions in the Import Disk Group dialog to properly import the disk group into the storage array.

Click Recheck 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.
