When it comes to copypool tapes, there is a *far* easier way to convert
those suckers to scratch. Run
        delete volume <volume_name> discarddata=yes
The next time there is a backup from primary pool to offsite pool, TSM
will write those deleted files to another tape. The window of
vulnerability can be minimized by running the volume deletes immediately
prior to the stgpool backup.

This is *much* quicker than bothering with updates and audits,
particularly if the tape volume is densely populated, or the tape media
is a slow-mounting and -seeking type like DLT.
