Can you try re-seating the cable? If it still does not work, you can
tell the sun to boot from a particular device. The device name is
terribly long, but tou should be able to say something like

boot /sbsu/esp@example.com,70000/sd@example.com,0:c

At least I think thats it. On a sun at work, I have it setup to boot
off an external disk, scsi-id 5. You use the "setenv" function in the
boot prom to set the "boot-device". Do a "printenv" find out current
settions.

My sun at work:

boot-device=/iommu@example.com,e0000000/sbus@example.com,e0001000/espdma@example.com,400000/esp@example.com,800000/sd@example.com,0:a
disk

Actually, I think that is much longer than it has to be. At home, I
boot off another controller, and the device spec is much shorter:

boot-device=/iommu/sbus/QLGC,isp@example.com,10000/sd@example.com,0:a

I'm sorry I can't tell more details on how these work. I got it to
work from following examples in the controller manual and a bit of
experimentation.

Actually, you might be better off with an old Sun drive.

That should not be a problem in itself. However, it may be the the
drive is scsi-2,3. The SS2 is plain old scsi. I have not been able to
get scsi-2 devices to work with built in controllers on SS2's and
5's. The add-on controllers, such as the ethernet/scsi combination
controller, does work.
