After a bit more thought, I believe I follow the problem through now. Our offsite copy tape pool supports multiple primary pools and IS subject to reclamation so presumably the full tapes in the primary (unchanging) pool will still be read on occasion to support reclamation on the offsite copy pool.
Thanks for clearing my head Richard.

Checking tapes out of a library will work to create empty cells in the library, but is problematic in that it is an "out of band" measure. TSM is enterprise software, with a rules set and regimen to assure that all pieces are consistent and aware of one another such that automated operations can work. It is implicit that investing in enterprise level software involves an equivalent commitment to enterprise hardware, with adequate capacity and performance - including all data being resident in managed libraries. By TSM conventions, tapes which leave a library are to be copy storage pool volumes marked as Offsite, where their life cycle can be tracked by automated facilities and be dealt with appropriately in all phases. For example, Reclamation will not sit in a stupor waiting for such a tape to be mounted, instead calling for mounts of the primary copy of the data, which is still in the library. As you can see from the Managing a Full Library topic in the Admin Guide, you have to go through gyrations to fabricate an alternate reality for primary storage pool volumes, including dealing with mount requests and allied handling of tapes which are outside the library. This is not something you really want to do. Richard Sims
