Error description

• During a backup, Tivoli Storage Manager server may detect
  ANR0379W a server database deadlock situation has been
  encountered; the lock request for the bf aggregate

  deadlock.  Then, the backup is aborted with ANS1301E error.
  The error occurs when COPY ACTIVEDATA is running at the same
  time for the active data pool in which data for the backup
  would be stored.
