I agree with Dietmar. 

Think of a missed ssh command to remote node (small network timeout for example), for a resize volume for example.

the lun will still be there, but wrong size, and if you do a live migration, it'll crash (and maybe data corruption).

Offline nodes is not a problem because when the get online their scsi 
bus will not have references to disappeared luns. Not reachable nodes 
posses another problem which will be a problem for other things too and 
must be handled by fencing.
