[TriLUG] SCSI Timeout: kernel? hardware?

[Janyne Kizer]

I have two servers that are consistently reporting what appears to be a
SCSI timeout error.  I have two other servers with the same model
hardware (one of which is literally a copy of the one below) that are
not reporting this problem.  The error that I am looking at (AAC:SCSI
Channel[0]: Timeout Detected On 1 Command(s)) always occurrs after the
"su(pam_unix)[12432]: session closed for user nobody" but as you can see
there is no time relationship.  I'm not sure what is going on here and
anything to point me in the right direction would be appreciated.  The
hardware is Dell PowerEdge 2400.  The OS is RH 7.2.  The BIOS and PERC2
are up-to-date.  I guess one of my main questions is:  Is this a kernel
issue or a hardware issue?
