Hi.
I have a 3 host cluster (5.1) with 1 datastore on shared storage (iscsi) over 1GB network. I want to replace my network switch to a new one. I only have 1 NIC on the iscsi storage, I have 2 NICs on each host (all going to same switch).
How to move over to the new network switch while everything is still running (this is my production cluster)?
Once I pull out the network cable from the switch that is going to the iscsi, are all of the VM's going to freak out and stop working? What if I moved the cable over to the new switch really fast (like 2 seconds) Would it tolerate it? What is best practice here?
Thanks,
