There are a few reasons. We have this happen all the time since we have 100+ tapes on the shelf (old soon to be retired system). 1: If a copypool tape is running reclamation it may need a "TAPEPOOL" tape to copy data to create the new "COPYPOOL / off-site" tape. 2: After a while expiration runs and the tape is no longer 100% full, it reaches the "reclamation" threshhold and runs reclamation to free up that tape. 3: A restore needs that tape and the data is not in the library.

I ran out of empty slots in my silo so I had to move some tapes to a shelf location. I was really careful to only move tapes that TSM says are "full" and 100% utilized. I now see a request for one of those tapes for space reclamation. 1 - Why is TSM calling for this tape? 2 - Should I mark all of my tapes on the shelf as "unavailable"? (I hesitate to do this because of problems that may occur if a restore is called that needs this tape) 3 - What will happen when expiration runs? (Will the tapes be called for?) Thanks! DaveZ
