A while ago (two small children in the house, so this was
back-burnered) I started having a very strange problem with the
original Sun CD-ROM drive in my Sun Blade 100 (August 2001 vintage).

I installed a second hard drive, a Seagate ST3120026A on the second
controller connector. I buttoned the machine up and started a Solaris
9 install from the 1of2 disk onto the new drive (figuring that I'd
move my data over from the original hard drive at a later time).
Everything went OK. I rebooted when the first part of the install was
done. Upon booting I inserted the 2of2 disk and got an error trying
to read the CD-ROM drive. I rebooted to the Solaris 8 install on the
original drive and could not access the CD-ROM drive from there
either. I can't boot from the Open Boot PROM either. I've been
running off the Solaris 8 drive since then.

I've fiddled with the jumpers (they all now say cable select) and
changed out the cable that connects the CD-ROM and the original hard
drive to the controller. The original hard drive is at the end of the
cable and the CD-ROM drive is in the middle. The other end of the
cable is plugged into the upper controller connector. The CD-ROM
drive does spin up on inserting a disk, or trying to do a read.

It won't read either the Solaris 9 disks that I burned onto CD-Rs
(images downloaded from the Sun web site) or the Sun supplied Solaris
8 disks that came with the machine. I have had no trouble, before or
since, installing Solaris 9 from these disks on other machines.

Both hard drives (one Solaris 8, the other 1/2 of Solaris 9) seem
fine.

Does anyone see anything I'm doing wrong? Any ideas?

Sigh. I never had any trouble with SCSI.
