SCSI reservation prevents data corruption due to concurrent access; it
cannot be used as replacement for proper STONITH as it does not affect
all other non-disk resources.

You need to combine SCSI reservation which something that actually
eliminates the node at which point it becomes much more simple to use SBD.
