Nothing will happen to Celerra ..failover does not get initiated because network is not available. Snapshots will be intact as well.
 I'm upgrading my datacenter core network switches on Saturday and due to space constraints I'll be taking down the entire network (i.e., can't fit the new gear without taking the old stuff out first).  As far as the Celerra is concerned, how is it going to react?  Is it going to attempt a failover to my standby mover (I have an NS42G) even though the standby mover has no network connectivity?  Should I do some sort of shutdown first?  I'm using snapshots and replicator V2 and don't want to lose the snaps or have to resync the data...I don't think I will, but I want to make sure.  Dan
