We first replaced only 8 of the drives, so that I could see whether all the tapes would mount there. I noted that LTO2s were mounting in the LTO4s readonly. However, this was the first time I tried to move data from an LTO2 pool since turning on encryption in the Library. At first I thought that may have something to do with it, but the LTO3 pools are not encrypted, and they mount up just fine.

Did that work, or turn up any anomalies? Technote 1269453 indicates that LTO2 tapes should be usable in an LTO4 environment, providing that the stipulated actions are undertaken. The technote doesn't say whether any path redefinition is needed to make it work, however. I'd use SHow LIBRary to do the most reveal on what TSM thinks of the arrangement. Beyond that, you may have to contact TSM Support. Richard Sims
