Barry,
My previous reply should allow you to build a new file system
on the rz0h partition which you should then be able to mount.
As for being able to boot Ultrix, you don't mention which system
you are running from. The boot command you gave should work fine
for a boot command run on a DS2100/DS3100 system booting off of
a disk whose SCSI ID is 1.
However, if you are booting off of a DS5000/200 (or any of the
follow-on products coming soon to a theatre near you) the
command string will look like this:
>>boot 5/rz1/vmunix -a
Where 5 is the id of the Base System SCSI TURBOchannel option (the
one on the CPU module...it could be 0, 1 or 2 if you were using
added SCSI host adapters), rz1 is the disk drive SCSI ID (following
your example) and the -a variant will bring it up multi-user.
You shouldn't have any trouble booting from alternate expansion
boxes or toggling between operating system variants (I do it all
the time here in my lab depending on which Third Party Hardware
vendor has customized which disk for their particular product).
I hope that this helps.
Thanx,
AJ

I sent the previous posting off just before I left after spending the day on the upgrade from RISC UWS 4.0 to 4.1. I just ran chpt -q on the disk and can see rz0h there. It shows as starting after rz0g ends. But I still can't mount it. In my need to get the system back on line, and due to my carelessness, I forgot to fsck the disk after the installation. Could that be what is causing the problem? I guess I don't need to worry about /usr, but I *would* like to use that nice disk space on rz0h... The only other weird thing is that I now have two disk expansion cabinets on the SCSI bus, and the second one contains the 4.0 system. But I can't boot off of it. The manual indicates that >>>boot -f rz(0,1,0)vmunix should do the trick, but no go. (The reason I wanted to do that was I munged the /etc/fstab file - gee *that* was fun. ;-)).
