I also have a suggestion. Before moving drmedia,
update the stgpool mount retention to a low value
and volumes will be dismounted if not used.

A few minutes later you will be able to move the
drmedia. When the process is done, return the mount
retention to the original number.

Alas there is no SQL table in ADSM with the mounted volumes listed.

I wrote a shell-script to look at the output of "query mount" and
dismounts them.

Works 99% of the time.  The 1% is the race condition between the query
and the dismounts.  There is a small gap the server can internally
issue a "dismount volume" or some process or session starts to use the
volume.  This just leads to an error message.  Conversely, a volume
can become idle in the gap and it will be missed.
