APAR status

• Closed as program error.

Error description

• During Tivoli Storage Manager for Mail: Data Protection for
  Microsoft Exchange Server 6.4 backup, restore, or query
  operations, the DAG name may be obtained from the Failover
  Cluster API.  The 6.4 release included the functionality to
  continue the backup/restore/query in those cases where the
  PowerShell command <Get-DatabaseAvailabilityGroup -Status>
  failed.  However, the following error is seen:
   "An Active Manager operation failed with a transient error.
    Please retry the operation. Error: Active Manager RPC
    operation 'GetDeferredRecoveryEntries' is not implemented on
    server 'EXCHSERVER1'. This may be due to an Exchange version
    mismatch."
  The processing should proceed, but in this case it fails even
  though the DAG name has been successfully found using the
  Failover Cluster API.
  .
  A trace of the problem will show that PowerShell failure to get
  the DAG name and then the successful return of the DAG name via
  the API.
