You say 'partition' but from the rest of your description it appears
you have guests on z/VM running with z/OS, correct? And your earlier
reference to "connect VM's" actually meant to connect guests rather
than z/VM systems?

If so, and if the DASD is not shared beyond this (so only among the
guests) then z/VM can simulate the reserve/release process by virtual
reserve/release (which does not involve the DASD subsystem). But you
must already be using that or your reserve/release would not do
anything and your data would be corrupted by now...
