Could also be a bad SCSI cable connection.

Subject: Re: How to diagnose scsi/disk error on M80
The previous disk was replaced by one of my colleagues. It was hdisk4,
not
hdisk1, which was why I didn't notice initially, but it was the same
disk
slot, connected to the same SCSI adapter.
I'm trying to go back over the information from the first problem but my
understanding was that the problems were broadly similar. However, now
that
I look I can see that there was a different pattern of error ids. There
are
a lot of the following:
0BA49C99 0701095003 T H scsi1 SCSI BUS ERROR
Typically a few of these, followed by a 35BFC499 Disk Operation Error.
Looks like it may indeed be some sort of termination issue, perhaps.
I tried the SCSI us Analyser, and that was clean, so I'm a bit stumped
at
the moment. I guess I need to get an engineer in to run advanced
diagnostics on the SCSI adapter and check the termination, which could
mean
two outages for this system: one to diagnose the problem then a second
one
to actually fix it.
