Our servers are designed just to do this -- be able to mount the disks
from one onto another server if a physical machine fails.

Easiest way to handle this is - move the disks but then RESTART THE
SERVER without them.  Then do a syncvldb.

If you don't have the "down" server running when you do the sync, it
will try to contact the old server, say, "Well I can't confirm with
the old server, you lose."


The other way to do this -- what I've done in disasters -- is move the
disks and then use "vos changeloc" to tell the vldb the volumes have
moved.
