There are several ways to achieve what you want to do.  The most
obvious would be to create the Vinum volume with only one plex and
copy the data across via the network.  You could then move the disk on
the OpenBSD box and create another subdisk/plex on it, then start it.
There's no way to keep the original data on the OpenBSD disk, since
Vinum requires a different format from native disks, and OpenBSD has a
(slightly) different on-disk format from FreeBSD.
