Yes you can buld bigger than 1gb. the problem if the VLC isn't aware
was that if the system crashes under VMS it would use the BOOT ROM
driver for the SCSI disk. For many of the 3100 series systems this
meant if you used a disk larger than 1.07gb and it crashed it would
over write the area that was in the 1st 1gb. if it never crashed it would
run fine as the VMS driver that is loaded was large disk aware. Later
systems that were SCSI had this fixed but I don't know about this one.

The easy fix is to build a system using boud volumes with the smaller
being under 1gb. Also reduce the swap to 5k blocks and put page
and swap files on secondary drive where they can be any size.

FYI: I only have one VAX that now has a 1gb disk, this has never been
a problem for me and I run a lot of stuff in rather small disks.

Not that I know of for VAX.

Not surprized. Enjoy!
