Multiple Disk Groups Refer to Foreign Physical Disk (Scenario 1)

What Caused the Problem?

A Contingent disk group considers a foreign physical disk to be a member of the disk group; however, the physical disk is a member of another 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 from inserting a disk group (from a different storage array into this storage array) containing a physical disk that was previously a member of the other foreign disk group.
To resolve this problem, you will need to remove the foreign physical disk, remove and then re-insert the physical disks that comprise the disk group (which has the incorrect reference to the physical disk), and then assign a local physical disk to take the place of the mutual physical disk. Follow the recovery steps below to fix the problem.
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 disk slot is reporting the foreign physical disk.

Remove the foreign physical disk.

Refer to the Details area to find which physical disks are associated with the disk group that has the incorrect reference to the foreign physical disk.

Remove each physical disk until they are all removed

After the Logical view of the Array Management Window (AMW) no longer displays the disk group you removed in step 4, re-insert each physical disk until all have been re-inserted into the storage array.

When all of the physical disks are spun up and recognized, the Contingent disk group should re-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.

Notes:

You will need to use the FORCE option since this disk group is missing a physical disk.
After the storage array completes the import process, the disk group transitions to a Partially Complete Disk Group state since it is missing a physical disk.

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 once you click Recheck.

a	Click Recheck to rerun the Recovery Guru.
b	Select the "Partially Complete Disk Group" problem in the Summary area.
c	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.
d	After the Disk Group transitions to Optimal, re-insert the foreign physical disk that you removed in step 2.
