Well, remember that in VxVM, rootdg (under normal circumstances) cannot be
shared or moved host to host. You need to create a disk group for that
purpose.

SDS is sort of similar. Unless you've created a shareable diskgroup, a.k.a.
a metaset, you won't normally be able to move the disks host to host.

Should note, however, that when one host owns a disk set, it OWNS it. That
is to say, it sets a SCSI reservation on the device(s) such that the other
host cannot take posession of. You can see this in format on the system
that does not own the disks: the disks show up unavailable/reserved.

Oh, if things get FUBAR, youll find yourself having to manually clear out
the SCSI locks/reservations. Breaking SCSI reservations/locks can be real
fun (not).
