as you see in one server the device is *marked* as open, in the other is not.

i need just to see open in both server,
if it is marked as open, xen refuse to boot vm with that device open, and i will not care about the filesystem that is contained in lvm.

when a device is mounted i can see the open status only in one server, so the open status is different between server.

the 3 servers see the same storage with same device path (as seen in pvsrv06).
