I am attempting to set up a new RAID under OpenServer 5, image over
the data from the old array (which is currently on its last leg), and
finally pull the old array with minimal downtime. I have the new
array already initialized and set up on the ADAC RAID controller. I
can't seem to get mkdev hd to address it properly. It either errors
out or addresses the wrong drive. Is there an easier way?

You probably don't want to image transfer an array. For that matter,
image transfers in general aren't generally a good idea (given that
there are circumstances where they do make sense).

I'd just use one of the Supertars to transfer your data:

But your next question is too vague. What OS (OSR5 tells us very little).
What did you actually do here - hardware, software, etc. See
http://aplawrence.com/newtosco.html and pay attention to the section
on how to ask useful questions.

What it sounds like is that you've setup a second array off the same
controller? I guess you might be able to make that work, though
I'm not sure about how fussy the controller logic is going to be about
moving things around, so I think the Supertar approach is cleaner
and quicker: you'd have been done with it by now.
