IC98094: FLASHCOPY MANAGER ON WINDOWS DOES NOT ACCOUNT FOR STORAGE FAILURES DURING VSS DELETE OPERATIONS

APAR status

• Closed as suggestion for future release.

Error description

• When an error occurs during a VSS deletion operation (VSS Error,
  CIMOM Error, Storage Device Error), the Tivoli Storage FlashCopy
  Manager VSS Requestor will remove the snapshot reference from
  its own local DB, log the error, and continue.
  However, the snapshot which was associated with the process that
  received the error is not deleted from the storage device as
  would be expected in an error situation. When this occurs, the
  snapshot on the storage device remains, but the Flashcopy
  Manager VSS Requestor is not aware nor is managing that
  snapshot.  In situations where storage volumes are tightly
  controlled, the storage device may run out of target volumes
  because this snapshot is never deleted from storage which would
  allow the volume to be returned to the free pool.
  Versions affected:  Flashcopy Manager Windows 3.1, 3.2, 4.1
  Initial Impact:  Medium
  Additional Keywords: TSM TDP DP FCM SQL Exchange MMC
  

Local fix

• Manually delete the flashcopy relationship(s) for the source
  volume that are no longer in use and return the target volume(s)
  to the free pool for future use.

Problem conclusion

Temporary fix

Comments

• We will provide a fix however the necessary changes are beyond
  the scope of what can be fixed in an APAR release. Therefore if
  there is a Flashcopy Manager windows release beyond 4.1, this
  problem will be fixed in that newer release.
