APAR status

• Closed as program error.

Error description

• If an incremental snapdiff backup finishes with a failure, the
  newly created snapshot is invalidated and should be removed from
   the filer.
  If that happens during the first initial snapdiff backup, the
  invalid base snapshot is not removed.
  After several failed backup attempts, the NAS shows the same
  number of base snapshots still kept on filer volume.
  
  Tivoli Storage Manager Versions Affected:   AIX , LINUX ,
   Windows client at 6.3 , 6.4 and 7.1 level
  
  Customer/L2 Diagnostics :
  
  At the beginning of the backup, the output shows :
  ----------
  Performing a Full Incremental Backup of volume '\\host\volname$'
  Creating Base Snapshot.
  Using Base Snapshot 'TSM_A860576A3C7B12345_VOLNAME' with
  timestamp 22.06.2016 08:20:00
  ----------
  If the incremental backup fails with at least one failure, the
  above snapshot should be removed, but the snapshot still exist
  on the filer.
  
  
  Initial Impact: Low

Problem conclusion

• The code has been changed so that in the case of the initial
  snapdiff full progressive backup failure the base snapshot will
  be removed from the ~snapshot directory.
  

Temporary fix

• A fix for this problem is currently targeted for interim fix
  package 7.1.3.3. Until the interim fix is actually available
  this information is subject to change at the discretion of IBM
