Mount retention is pre-empted to gain access to a drive, providing that
no process or session is engaged to use the drive and media.
See that msg in http://people.bu.edu/rbs/ADSM.QuickFacts for reasons we
have experienced. Check your Devclass MOUNTLimit as the most common
cause, plus your Activity Log for accompanying messages.

        Suddenly (I think) I am getting a LOT of ANR8447E messages.
A "q
mount" shows several drives in an "idle" state. My mount retention is
set
to '3'.  I thought that the mount retention would be preempted if there
was a need to mount  a new tape. Can someone confirm or deny this for
me?
I am finding if I manually "dismount vol xxxxxx" the problem goes away
for
a bit until I get several "idle" drives again.
