4 GB is luxury.  2 should be enough.  I ran 2-GB system disks on VAXen 
for about 15 years.  Maybe 1 GB if you are careful, but go with 2.

If you have no disks other than the system disk, go with 4.

Indeed.

I really, really, really, really recommend HBVS.  The only real 
disadvantage on VAX is that MINICOPY doesn't work.  (Well, technically 
it works between disks which have direct connections only to VAX systems 
as long as the corresponding (DIS)MOUNT commands are issued from a 
non-VAX in the same cluster.)

Just set the system up on a single disk, change MODPARAMS to turn on 
HBVS, shut down, enter both disks as the boot device, and reboot.

At least I think the above will work.  What definitely works is the 
above without adding a second disk as the boot device at the console, 
then MOUNT/SHADOW to add a new disk then, after the copy is complete, 
shut down, add the second disk (and the first, of course, if not there 
already) as boot device, and reboot.  The shadow set will automatically 
reconstruct itself after a reboot (i.e. don't have any MOUNT commands 
for the system disk in the startup---but you do need them for other 
shadow sets).
