[SunHELP] SCSI transport error

[Joe Serra]

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: /sbus at b,0/SUNW,socal at 0,0/sf at 0,0/ssd at w2200002037c98530,0 (ssd238):^M^M

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
