RA disk driver in Ultrix

[Steve Grandi]

We're about to bring Ultrix-32m up on a VAXstation and I'm wondering about
the RA driver.  Does it have the various RA disk types hardwired in or does
it determine the disk size and geometry using the MSCP protocols?  In other 
words, If I try to bring up Ultrix on my 319 Mbyte Emulex/Maxstor 
MSCP-look-alike disk, what will happen?  For that matter, will DEC's new RD54 
disk plug-in and play under Ultrix-32m version 1.2?

If Ultrix was still an exact copy of 4.nBSD, of course, RA disks that don't have
partition tables hardwired in the driver would be unusable (unless you have
sources).  However, Ultrix features on-disk partition tables, so there is no 
reason that I can see to hardwire knowledge of disk sizes into the driver.
