[KLUG Members] RAID problems.

[adam]

Okay, I've got a problem.

I've inherited a RAID.  Well, that's what it's supposed to do.

The RAID card is a DPT I20 SCSI card, 40 MBytes a second, etc.
The SCSI drives are IBMs and Seagate Barracudas.

Okay:  The drives (9 of them) are arranged in a RAID 5 format, and make up
about a 70 GB RAID.  The problem is, when data goes on, it becomes corruped.
Any ZIP file that is put on it is corupted.  this is a problem.  The main
hard drive, an IDE, will let data be stored in uncorrupted format.  Once
it's put on the RAID:  corruption.  It's like putting things into the
government.  It goes in clean...


Anyway, the hardware/software doesn't show any errors at all.  No buzzers,
no errors in the logs, etc.  The only thing that I can think of is this:
a.  some of the drives were very, very hot. They are cool now, but before,
three of them were too hot for their own good.

b.  Five of the drives aren't in the actual case:  4 SCSI drives are in the
"host" computer, while 5 are in another case.  So, 4 are internal, then 5
are connected via the external SCSI port, which is then changed back into 68
pin SCSI again, and connected to the rest of the drves.  The total cable
length is maybe, oh, 4 feet total from tip to tip of the SCSI cable.  Maybe
a little more...

Has anyone else had this problem?  This is like, our MAIN storage area, and
at first, it was suspected that a program was causing the corruption.
However, now that I've checked things out, I'm worried...
