I have an Ultra Enterprise Server 450 running Solaris 8. Recently, I have
been receiving SCSI errors. On the system console they looked something
like this (see below for excerpts from /var/adm/messages):
Oct 13 03:14:32 athena disk not responding to selection
Oct 13 03:14:33 athena scsi: [ID 107833 kern.warning] WARNING:
/pci@1f,4000/scsi@3/sd@1,0 (sd1):
Oct 13 03:14:33 athena disk not responding to selection
I thought it might be a disk going bad so I found another disk and put
it in the machine so I can move the data over to the new disk. After I put
the new disk (but before removing the disk I thought was going bad) I
noticed that the disk identified in the SCSI errors has changed from the
one I thought was bad (sd1) to the one that I just put in (which I
attached as sd2). The console messages now look more like this:
Oct 13 03:14:32 athena disk not responding to selection
Oct 13 03:14:33 athena scsi: [ID 107833 kern.warning] WARNING:
/pci@1f,4000/scsi@3/sd@2,0 (sd2):
Oct 13 03:14:33 athena disk not responding to selection
I'm starting to think that the problem might not be the disk and that it
might be a bad controller or something else all together. Does anyone
have any ideas on what else I should take a look at? FWIW: The
second set of errors appeared while trying to copy the data from the disk
at sd1 to the disk at sd2. Excerpts from /var/adm/messages below:
As is normal practice, I will summarize for the list.
