[SunHELP] SCSI transport error

[Leslie V Brigance]

Joe,
I have had very similar, but not identical, problems with a flakey gbic.
One time it was the gbic on the controller and a couple of other times
I had the one in the SENA causing the problem.
As you are probably aware many of the gbic modules produced by
Vixel have flaked out.
I find the best results with the ones made by IBM.

If dual pathed can you replace the gbic modules, one at a time,  with
system up?
Or have you already tried replacing them?

Les,

Type: A5200
Connection : Fibre (GBIC)

Thank you,
Joe

Hi all,

I am on a client site and having problems on a E4000 running Solaris 2.6,
with 6 CPUs, 4GB memory and 4 SENAs. Using Veritas Volume Manager, all
disks on RAID5s. That is their NFS server.
/var/adm/messages shows the following error:

Nov  9 11:23:01 ang056 unix: WARNING:

The SENA that contains this disk does not show any error/problem. There was
the same error for a different disk ( c7t38d0, same filesystem, same SENA)
early this morning and i put it offline, error gone for that disk and
started again with the one above (c7t58d0). I cannot offline this one
without causing problems to the filesystem.
I noticed that luxadm display would freeze, for that particular SENA, while
the system was "giving up".
Can someone help me on this?

Many thanks,
Joe
