Can anybody let me know on 'How to find the list of Volumes associated
with a backup, from the schedule name (or) nodename?'

There is no real way to determine what volumes were associated with a
specific backup.  The Volumeusage table is no good because it
contains all primary and copy storage pool tapes associated with the
node, regardless of date.  You could bracket a time period in the
Activity Log and try to discern tape usage by virtue of mounts, but
that's messy, and doesn't account for volumes which happened to
already be mounted (residual tape - or disk, for that matter).  You
could try doing a Select from the Backups table, again trying to
isolate by time period, but that's expensive to run and doesn't
necessarily correlate to a session.  Consider also that, at any time
thereafter, the objects may move to a different volume.

In any case, the nature of an Enterprise level product like TSM is
that you should not need to know this information, as is the case in
many virtualization technologies today: the managing subsystem takes
care of data provisioning, and "you don't need to know".
