APAR status

• Closed as program error.

Error description

• A restart of the Tivoli Storage Manager for Space Management
  recall daemon (dsmrecalld) may destroy all DMAPI sessions in
  use by dsmmigrate processes.
  As a result the dsmmigrate processes will not migrate any
  further file(s). Instead you will find the following messages
  in the dsmerror.log for each file that migration fails for:
  ANS9511E dsmmigrate: cannot read DM attributes on session
  512B79F800000000 for
  file: name = /test/.SpaceMan/dmiFSState handle =
  C0A865D35118AE7D-000000000BC53018-0000000000000000-0001000200000
  000 token = DM_NO_TOKEN. Reason : Invalid argument
  ANS9084E dsmmigrate: /test is not managed or not locally managed
  by space management.
  
  The session id, the name and the handle of the ANS9511E message
  are the same the whole time, until the migration process ends.
  
  Tivoli Storage Manager Versions Affected:
  Tivoli Storage Manager for Space Management on UNIX:
  6.1, 6.2, 6.3, 6.4
  
  Initial Impact:
  Medium
  
  
  Additional Keywords:
  TSM, dsmrecalld, DMAPI, session, migrate, recall
  

Local fix

• Do not restart the dsmrecalld while dsmmigrate processes are
  active.
