IT32853: STORAGEPOOL TIERING THAT EXCEEDS DURATION SETTING CAN LEAVE SESSIONS IN A STATE THAT DOES NOT ALLOW CANCEL.

APAR status

• Closed as program error.

Error description

• When a tier to tape or tier to cloud process is run and that
  process has exceeded its processing duration time one or more
  sessions may fail to terminate.  Those sessions (always a worker
   session) will not stop and cancel session will not affect it.

  Temp Workaround:
  
  Stop using duration to manage how long the tier process runs.
  Issue a 'cancel proc' to the process when you want the process
  to stop.
