Next time it happens, try :  q session f=d

That will show you if a client restore session still has the tape mounted.

Subject: dismount volume in use?


All,

TSM 5.1.7.2 on AIX 4.3.3, 3570 library.  I have a curious problem in that
occasionally, when TSM finishes a process, it fails to mark a 3570 volume
status as IDLE.  It remains IN USE, so is never dismounted, and ties up
the drive.  So reclamations just sit there (waiting for multiple mount
points), and in a few days when scratch tapes are gone, backups start
failing.

There are no AIX errors, TSM errors, or library hardware errors.  The tape
stays in the drive, and TSM says its IN USE, but never uses it.

Anyone seen this before?  Is there a way to see what has the volume IN
USE?  Change it to IDLE? Or forcibly dismount the IN USE volume?  The only
fix i have found is to halt and restart TSM.  Not an optimal solution for
us.  Thanks for any info.

ANS8001I Return code 11.

status: IN USE.
