That is true and easily corrected, but what Richard details in QuickFacts is more of a problem. Last week a user made a major upgrade and kicked off a backup three times the size of the disk pool, which quickly filled, pushing other clients to the next pool. Since client1 of a group grabbed the filling tape, while its tapemates, all on the same schedule, started mounting scratch. Thirty eight tapes with a few inches used, all subject to "move data" the next day.

We have found that if you have a storage pool's collocation parameter set to Group, but you have nodes that aren't in a collocation group, TSM treats each such node as if it were in its own group - thus, each such node's data gets written to its own set of tapes. If you have a lot of un-collocation-grouped nodes writing to that storage pool, it will put a lot of tapes into the filling state.

Duane - See Tape leak and Shrinking (dwindling) number of available scratch tapes ("tape leak") in http://people.bu.edu/rbs/ADSM.QuickFacts for the standard reason for this.
