Jane, you mention that ULTRIX no longer fits on a 300 Mbyte disk.  I suspect
part of the problem, perhaps even most, is that you are doing a basic
installation or, at least, taking the defaults for where various file systems
get put.  My suggestion would be that:

a) You go ahead and install ULTRIX with its root on rz0, the DEC disk.  That
gives you an easy installation.

b) Put other file systems, including the swap areas, /usr and /var on
the other drives.  A swap area on each of the Impris drives, /usr on one
and /var on the other would (without, I admit, seeing much about how
you are actually using the system) appear to balance your workload to
the drives.

c) When you newfs the Imprimis drives you need an entry in /etc/disktab
that describes the geometry of the drives and probably a patch to
scsi_data.c, which is used in building the kernel, in order to get the
most out of them.  Something I recommend pretty often is to require your
vendor to supply those to you or not buy the drives from them.  You
can see if you can still get it.  If not, the net is probably full of
people who've already brought the drives up and can supply that info.

d) On one of the new Imprimis drives, put a copy of the root file system
you are normally using, in an a partition on that drive, as a backup.
Be sure  to either config a kernel to understand it's booting from that
drive or always boot genvmunix from it.  Having a backup root
partition can make you look awfully smart sometime.

Hope this helps.
