Hi Christian, On AIX you can indeed use lsdev -Cctape to see your tape devices. My best guess to what you describe is that the path from the drive to the host is failing. So have a look a the library and all SAN components to see if you can see the drive there.
Also is your TSM server a standalone machine (e.g. Full SMP or separate box) or is it an LPAR. If it's an LPAR does it use a VIO Server? What version of AIX and (Atape) drivers are on the TSM Server?

But I wonder if their is any command such cat /proc/scsi/scsi in AIX or cat /var/log/messages |grep -i LTO The reason why I'm asking is beause one of my tape drives it totally gone from the AIX environment. I run cfgmgr -v to auto-detect it and then when I run lsdev -Cc tape I did see all drives but one of the RMT was in Defind mode or something similar. So I try to remove the RMTx Device node and run cfgmgr -v again but now can't I find it anymore. I have try to remove all my Device Nodes for Tape and Library and reintall the drivers but still. I don't see my drive anymore. If I run "q san" I don't see it in TSM either. Any suggestions what's going on? I'm going to see if I can get access to the SAN Switch and the library (TS3500) via IP. But so far I don't have any access so everything that can help me in AIX to be 100% sure it is a Switch or Library problem should help. I look in errpt also and I see a Adapter Problem but I can't see what it is. Any good switches to get a better explanation of a error in errpt?
