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?

Met vriendelijke groet, with kind regards,
Richard van Denzel

Subject: [ADSM-L] AIX question

Hi Everyone,
This is more a AIX question then a TSM question.
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?
