So I have a 3 node cluster of Hyper V 2012 Servers.
They are connected to a stack of switches. All physical network connections are run through this stack.
I need to take the switch stack down for a few minutes to update the firmware. The switches will be 100% down.
Will the Virtual machines be ok, other then being inaccessible during the firmware update?
Or will I have to shut down the failover cluster, update the switches, then bring the cluster back up? I'd like to avoid that if possible...
