You refer to both a library manager and a TSM server. I assume the TSM server shares tape drives with the library manager. If the paths from the TSM server to the drives are still on-line, that may explain part of what you're seeing. I would have thought off the top of my head that taking the drives off-line from the library manager would have disabled them from the TSM server as well, but you probably should do a "Q DRIVE" on the TSM server that isn't the library manager and see what comes up.
Are you allowing SAN discovery? I wonder if the library manager is discovering working paths to the drives and working around the paths you're disabling? (My former sites were always too timid to trust SAN discovery, so I'm not sure what I envision is plausible, but since what you're seeing isn't what you expect, it's time to think of ways we could be surprised.) It shouldn't matter, but which TSM level(s) and hardware platforms?
