RS6000/320: SCSI Pinout/external SCSI disk

Post by Dana Roo » Sat, 22 Dec 1990 04:25:43



We have an IBM RS6000/320 and want to try third party external disk
on it.  Does anyone have the pinout of that odd 60pin connector IBM
uses for SCSI?

On a similar subject, anyone else out there had success putting third
party disk on a RS6000 and making it work?

Several people have attached third-party SCSI disks to their 6000s, in
fact one poster brought up a 6000 with 3rd-party SCSI disks *only*.  The
machine is quite intelligent in handling SCSI disks, unfortunately it
doesn't carry over to the SCSI tape drive interface :-(

If you don't get a response to your pinout query let me know and I'll
test the pins of my cable (non-IBM) while I'm doing my spring-semester
preparations in early January.  This is assuming I don't receive death
threats from "Cable Manufacturers of the World".

1. problem with a scsi external hard disk on a RS6000 43P (724804Z)

I'm trying to add a scsi external hard disk (9 Gb) on a RS6000 43P
(724804Z), AIX 4.2.1
Existing internal configuration: 2 scsi disks (id 4 and 5), 1 CDROM (id 3),
1 tape (id 0)
The behavior is strange:
- external disk with scsi id 2 -> boot OK, but disk not recognized
(lsdev -C -c disk)
- external disk with scsi id 1 or 6 -> doesn't boot. Error message: 0208051x
(x = 1 or 6)

I tried many different configurations, in vain.
Problem with external scsi? Incompatibility?
Thank you for advices.
