Logically removing a physical resource after physical removal

Follow these procedures to remove a physical resource from the DS Storage Manager after it has been removed from the server or expansion enclosure.

Problem

Follow these procedures if you have removed a DDM or expansion enclosure that was in use but have received an error message or log entry stating that the DDMs or expansion enclosures can no longer be recognized by the DS Storage Manager.

You are not required to perform these procedures, and you will not receive an error message, if you physically remove a DDM or expansion enclosure that is not in use. The resource will no longer appear in the list of physical resources in the summary tables.

Investigation

Follow these steps to physically replace the DDM and then properly take the DDM offline before physically removing it again:

Insert the DDM back into the enclosure.
Take the DDM offline through the Status page of the DS Storage Manager.
Once the DDM is offline, you can physically remove the DDM.

Follow these steps to remove the logical resources that were contained on the expansion enclosure:

Use the Modify Storage Unit -- Specify DDM packs page in the DS Storage Manager to logically remove all DDMs that are associated with the expansion enclosure.
Close the associated error log entry on the Logs page of the DS Storage Manager.

If, after you complete all of the steps above, you still receive an error message, call IBM Support.

IBM Support personnel can determine the cause of the problem and find the appropriate resolution.
