Angelos, I guess you haven't read much about TSM and in the past you worked with other backup solutions. Your question is not uncommon, why should one think TSM has a different internal behaviour and tape management than other products...
I can't give you a complete introdution in a few lines, I'll just try to point out some facts about tape management to help you understand what made your TSM server "unhealthy": TSM works with a TSM database and storage pools. The database holds a "mirror copy" of the directory structure on your clients. It also has information on older versions of files that are already deleted or overwritten by new data. The database entries point into your storage pools on disk (diskpool in the TSM server) or tape. Now when TSM needs additional tape space, a new (scratch) tape is allocated. The tape status is changed from scratch to private an it gets defined into a (tape-)storage pool. When all data on the tape has expired or has been moved to a new tape (space reclamation), TSM returns the tape into your scratch pool. There are no sessions on a tape that expire after a predefined number of days. With the backup method "incremental forever" TSM doesn't retransmit any data that has already been backed up. When there aren't too many changes on the client, a tape can survive years without having to be reclaimed. To come back to your problem: The tapes you wanted to check in as scratch tapes are full of data, data your TSM server still needs (when you have to restore a nodes data). The first thing you have to do is: get new tapes to keep TSM running. The second thing: think about getting a larger library with enough space for ALL tapes TSM needs. Otherwise you could become a tape-disc-jockey very soon (8->). Good luck!
