We will appreciate if someone can work with IBM support to report this
problem. SAN Discovery is a very important TSM function and it is widely
used by our customer.

We had this problem as well.
Our dedicated HBAs would just randomly log out of the Clariion. Presumably
when a SAN Discovery "probe" went out. We couldn't get it to log back in
without a reboot. A reboot also caused another Probe though, so we'd only
be up for about 20 minutes. It was a major outage at multiple data
centers, lots of visibility. IBM support was trying to upgrade firmware
and drivers but nothing worked. Finally, a guess worked out and I turned
off SAN Discovery and the problem went away. Ever since I've been
terrified of SAN Discovery! (TSM 5.4.1 at the time)
Regards,
Shawn

Re: [ADSM-L] Tape Drive SN issue
No, tape and disk reside on different fabrics. There are 7 tape HBAs, 3
of which go to physical tape, two of those have drives with this problem.

I am not aware of this problem. Are you putting disk and tape under the
same HBA?
