NO! Remember that a copypool is a complete copy. So everything that is offsite is onsite.
TSM does not need the offsite tapes to reclaim them! 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. Or run reclamation less often, like every second day. If you don't run reclamation you could have 100GB tape with 1KB used, stuck in your vault. 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. Miles Hmm, I saw a suggestion in the TSM 4.2 admin guide to disable reclamation for the copy stgpool (specifically) to avoid a situation where tapes gets sent off site and then it wants them for the reclamation. But of course, for the other stgpools, reclamation does make sense. Much appreciated the pointers...big help, thanks! -Dan Foster IP Systems Engineering (IPSE) Global Crossing Telecommunications ---------------------------------------------------------------------------------------------- Miles Purdy System Manager Farm Income Programs Directorate Winnipeg, MB, CA [EMAIL PROTECTED] ph: (204) 984-1602 fax: (204) 983-7557 "If you hold a UNIX shell up to your ear, can you hear the C?" -------------------------------------------------------------------------------------------------
