This a hypothetical situation. In this situation the needed tape from the copy pool is not available. I realize that the data would be lost but how what you do next?
if we were still running v5 of TSM we would do a move data (MOVE VOL XXX) to save what we could then delete the volume (DEL VOL XXX). We would lose some data but the next backup cycle would rebackup any missing active data. Since we are now running v6 with dedup it seems like the process would be different. Each volume no longer contains a complete set of files. They now contain parts of files.

We are currently using dedup and I can't come up with a good answer. Ok, our primary storage pool is using dedup. Something (corruption, whatever) happens to one of the files in the primary pool and the data needed to recover the file in the primary pool is not available. I attempt to do a restore of the corrupt file and the needed tape is not available. How would I go about fixing that kind of a situation? Back before we started using dedup we could just do a move volume to save what we could and then do a delete volume and the next backup of the server would straighten everything out. We might lose inactive copies but the next backup cycle would catch the missing active files. With the way dedup works I'm not sure what we would do. Any suggestions?
