I feel strongly that SCSI devices likely to be shared among many
devices in a cluster must have persistent reservations available to
allow reservations to be modified and broken without crashing all the
other systems.  For Sun, the right answer is "invocable" by the
initiator, implying "allowed" for the driver and "required" for the
medium changer.
