Had the data been migrated to tape?  Backed up to a copy storage pool?  If
you don't have a backup of the data (backup stg disk copy), then you can't
restore it.  If it had been migrated to tape already, I wouldn't worry about
it: delete the volume:

delete vol d:\data01.dsm discardd=yes

Replace with the real name.  Then recreate the volume:

define vol d:\data01.dsm formatsize=whatever

If you don't have the data anyplace, the next time the clients backup there
data, they'll resend anything they can that had been in that pool.
