The only way that I know of to determine what tapes are needed is via an
undocumented command:

     SHOW VOLUMEUSAGE node

Beware, this is not a fast command - I suppose it depends on the size of your
DB.  The command will show you which tapes a node is using.  It will only
include backups (not archive), and it is for all file systems.  It does not
actually move any data, or ask for any mounts.

There is no way that I am aware of to preload files from tape back to the
storage pool.  You could use the Move Data command, but that would take all
of the files from the tape, so it is not very discriminating.

Subject: Can I preview a restore of a filesystem

I will be restoring a filesystem which had been incrementally backed up over
time
to an exabyte tape library unit. I would like to pre-load all the volumes
necessary for the
restore of a filesystem before starting the restore. Is there a way to
"preview" the restore
to determine which volumes will be needed ???

Environment
AIX4.2
ADSM 2.1.12 (server)
ADSM 2.1.0.3 (client)
Exabyte has 10 slots, one drive and very slow and old.
