We've been using GPFS-directed HSM for a while now,
working quite well (with a few bugs, but they're
being worked on).

The 'problem' I'm seeing is the mounting of HSM
media (tapes, in particular) during the running of
an incremental backup. Since we have the requirement
that nothing can be migrated without a backup in
place, this just doesn't make sense to me.

It's also frustrating that I don't see any type of
info on the server after a recall as to the size of 
the file being recalled, etc. - much like you would see 
after a backup, restore, archive or retrieve (separate
from the issue above).

Server and client (BA and HSM) all at 5.5.1.1 (upgrade
to 5.5.3.x when I can get downtime in a month or so)
on SLES 10.

Any ideas?
