Ah, that is a good point, when put that way. ;) > But you are correct: You could send a tape out Monday, 10% used (90% percent >reclaimable). Reclaim it during the day (Monday), and ask for it back Tuesday. With >LTO tapes this can be mitigate by using a high reclaim, like 90%, or 10-to-1.

Duly noted, thanks. > Also make sure that you don't use collation on a copy pool, unless this is what you >REALLY want. In general I don't think you want to you. Not using collation will keep >fewer tapes, more full. Preventing tape thrashing, if you like. Indeed. I read about that...sounded great at first, but then soon realized that potential for tape thrashing was probably going to be too great given how we manage the tape environment here. So it's definitely not going to be enabled. (But I appreciate the TSM folks having made that an available option. Options are always great to have, even if not used.) -Dan Foster IP Systems Engineering (IPSE) Global Crossing Telecommunications Internet: [EMAIL PROTECTED]
