Yes, but when it expires a copypool volume, it mounts volumes from the primary
storage pool to copy data that is not expired to a new copypool before
releasing the copypool volume to scratch. This may require many mounts of
primary storage pool volumes to return one copypool volume to scratch. Seems to
me the more efficient method would be to spin thru the copypool volume, copying
still valid files to the new copypool volume, just like is done when a primary
storage pool volume is reclaimed.

when you issue a "del vol xxxxxx discard=yes" is only delete's the information
on the "database" and the "Volume History", it never calles for a mount of the
volume. Then when inventory runs it then delete the entries in the database.

The copypool volumes are normally off-site, in a vault with no tape drives.
