Error description

  • The Library Client (LC) crashes when there are no available tape
    mount points on the Library Manager (LM).  Three conditions need
    to be in effect:
    
    1) A FILE Device Class as the input source storage pool
    2) During a move operation from the FILE Device Class storage
    pool (i.e. MOVE DATA, Migration, or Reclamation)
    3) Output destination needs to be to a SHARED library (LM with
    no mount points available)

Local fix

  • Attempt to reduce LC mount requests to prevent the LM from
    having no drives available.  Example: Schedule move operations
    such as Migration and Reclamation on LCs when there is reduced
    tape drive activity on the LM to make sure drives are available.
