IC89967: 6.2.0 OR HIGHER LIBRARY MANAGER CAN CRASH WHEN USING LIBRARY CLIENTS LOWER THAN 6.2.0 WHEN RUNNING MOVE DRMEDIA

APAR status

• Closed as program error.

Error description

• Tivoli Storage Manager servers at level 6.2.0 or higher that are
  library managers can crash under these conditions:
  
  - Library clients are at a level lower than 6.2.0
  - Library clients are using MOVE DRMEDIA
  - The tape library is SCSI or 349x, but not ACSLS
  
  Library clients which are also at level 6.2.0 will not cause the
  library manager to crash.
  The last message logged to the library manager's activity
  log might be this:
  
  ANR6696I MOVE DRMEDIA: CHECKOUT LIBVOLUME for volume 123456 in
  library LIBRARY starting.
  
  Customer/L2 Diagnostics :
  The call stack from the crash will resemble this:

Local fix

• Do not issue the MOVE DRMEDIA command with the REMOVE=YES
  option. Using CHECKOUT LIBV and MOVE DRMEDIA with REMOVE=NO
  might provide equivalent function until a fix is available.
  -
  Upgrade library clients to 6.2.0; the problem does not
  occur with 6.2.0 or higher library clients.
