"SHOW VOLUMEUSAGE node" is almost what I need. If there was a way of
limiting the
output to report on a specific filespace (filesystem), that would be
perfect. The problem I'm having is
that the filespace I have to restore a spread amongst 55 8mm cartridges. My
tape library
can only hold 10 at a time. If I knew which volumes the filesystem
(filespace) was on,
I could load the library with just those volumes, or the first ten, then
start the restore and go home.
What I have to do now is wait for ADSM to tell me which volume to mount next
as it's restoring.
I believe LEGATO has such a feature.
