Hi first of all after thinking about it, I should
have stated that my machine was an SS5/70 running Solaris 2.7.

Thanks go to
Alan Orndorff
David Anthony
Sean ( You know who you are!)

Bugs in the esp driver were mentioned by Alan Orndorff
which caused this in eariler releases of Solaris specifically: 2.3 FCS
which was addressed by bugid 1174191.

David Anthony suggested looking at termination
(spcifically autotermiantion, which wasn't in use.) I never use it.

Sean, I think hit it on the head, as the disk in
question was under heavy I/O at the time.
The disk is at the end of a long scsi chain, approx. 6 feet and is
shared with another disk, so it is probably on the
ragged edge of the SCSI specs:

I haven't had the opportunity to shorten the cables, but,I suspect that
when I do, things will clear up.

Thanks for the help, it's greatly appreciated.
