Hey, Josh. You could write a Perl script (or pick a language) that manages these canisters. It can track which volumes are in each canister, check all their %util and %recl and generate a canister %util/%recl. Then you can have your script issue delete vols or move datas when a canister is sufficiently empty. Of course, if you do this, you won't be able to use the stgpool's pct_reclaim to do reclamation, but that's OK because your script mimics the reclamation. It would be like an offsitepool with superlarge tapes, so _hopefully_ you'll get volume usage similar to what you're seeing now. It should also be pretty simple to write.
Personally, I don't like either the brand new copypool or the import/export/backupset options. They seem like they'll add too much drive utilization.

I have setup DRM for several accounts who used open containers and I have setup poor man's tape rotation without DRM with open canisters, but I have never implemented a locked canister solution. The problem as I see it is that not all the data on the tapes will expire at the same time. So what will happen is that some of the tapes in the canister are available for reclamation and then return to the data center, but other tapes will not be available at the same time, this will cause the tapes in the canister to be out of sync. I have thought of 2 ways to potentially deal with this problem: 1) Every week we can create a brand new copy storage pool and backup the primary pools to the offsite pool. After 3 weeks all the data in the pool can be deleted and the tapes brought back onsite. This is not utilizing TSM's incremental backup storage pool feature, but would guarantee that a complete set of data was taken offsite each week. 2) Use either import/export or generate backupset to create fresh tapes every week. -- Joshua S.
