Issue: The correct procedure to forget storage-volumes on VPlex was not followed and the LUNs were removed/unmasked directly from the backend array. Running the storage-volume forget command fails and storage-volume unclaim fails with " One or more given storage-volumes could not be unclaimed. These storage-volumes may be in use or unavailable. " The storage volumes in question show as unreachable and unusable: Symptoms: Storage-volume summary shows one or more storage-volumes as unreachable. storage-volume summary reports unreachable and critical-failure for the related volumes: VPlexcli:/> storage-volume summary SUMMARY (cluster-1) StorageVolume Name IO Status Operational Status Health State ---------------------------------------- ----------- ------------------ ---------------- VPD83T3:600601603d903a00884779a43a123456 unreachable error critical-failure VPD83T3:600601603d903a00b6d5d15a39234567 unreachable error critical-failure The 'use' property of the storage-volume(s) is 'unusable'.

The " storage-volume unclaim " command is failing as one of the internal commands " amg movespecificdisks " fails with " the specified storage is not in a spare pool ". There is a pie amf with no slices still above the disk which is the cause of this failure.
