Is the VAX SCSI based?  I've not tried this with a VAX, however, it 
does work with my PDP-11's.  Hook the SCSI disk up to a Unix box, and 
then use 'dd' to copy the 'raw' disk to a disk image.  Something like 
the following:

	dd if=/dev/sda0 ibs=512 obs=512 of=/tmp/vax_image.dsk

Obviously at a minimum you'll want to change the device file.

If you have enough free space on the VMS system, you might even be 
able to do this under VMS, though I personally would want to be 
booted from a different drive.  I've copied all of my RL01's and 
RL02's for my PDP-11's under VMS.
