We are running a cluster of a 9000/360 server with two 9000/370 clients.
We have several disk drives connected to the server, including 3 hp-ib
connected drives and four SCSI connected drives.

Ever since we added the SCSI drives, we have had a certain trouble with
them.  We occasionally get data errors on reads and writes.  For instance,
we tried an experiment.  We used cp to copy a 5 Mb file.  Then we used
cmp to compare the original to the result.  Out of 10 copies, 4-6 of them
fail.

We had this problem on our 350, and now we see it on our new 370.  The new
machine has a new drive, controller, cable, etc.  The only thing it has
in common with the old machine is the O/S, which is HP-UX 6.2.

We have been working with hardware and software support at HP since 11/1,
but they don't have any answers yet.  Have any of you seen this problem?
Any ideas about what we might try next?

Thanks in advance,

Clark
