It seems that this is possible--several respondents are doing it now. Dr.
Tom Blinn (as helpful as always!) pointed me to the Software Product
Description for Digital Unix to find out if the configuration is SUPPORTED.
It doesn't seem to be (although the SPD doesn't specifically disallow it).
Despite that, we've decided to try it based on the experiences of those
doing it now. It was also pointed out that it's important to document the
exact configuration of the controller (which drives on which ports, slot
the card's in, etc) to be able to recover in the event of a card failure.
We're going to leave a duplicate of the root partition and a small usr
parition on the existing stand-alone disk. We'll also have all the
utilities we might need to recover the system.
The console manual indicates that you can define multiple boot devices. We
haven't tried it yet, but the hope is that in the event of a raid
controller failure the system will fall-back to booting off the built-in
disk. If not, it's easy enough to manually boot to that drive.
Now, if I can drag myself out of bed at 5:30 on Sunday morning we'll see if
we can make it go!
