vgscan looks for pvs with associated volume groups.

vgchange -a y marks them as active and available to the system.  It's

If you want to share vgs between multiple Linux systems you'll also want
to make sure there are no name collisions.  If you want multiple guests
to use the volume groups simultaneously you should use the LVM
clustering lock manager.
