Sounds like AIX has lost the drive, so duff drive, zoning etc...

You could do a cfgmgr -vl (name of fcs port the tape is down) to do a 
quicker cfgmgr.

errpt -a will give you more info.

Have we got multiple drives down the same HBA? i.e. is the hba & cable 
good?

[ADSM-L] AIX question




Caterpillar: Confidential Green Retain Until: 08/08/2009 



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?
