Charles,
In addition to all the other good answers to this post, you can add this to
your argument
with the dba's. TSM is NOT a tape management system in the classic sense of
that type of
product. Classic tape management systems returns a tape to scratch after some
policy driven number
of days. TSM only returns a tape to scratch when it is logically empty.
The rman page 85 note simply doesn't apply to TSM.
Hope this helps,
Bill Colwell
