I had a power outage on one of our ESX 4.0 hosts last night. We run a 2 ESX host cluster via VCenter so all those Virtual Machines shifted to the other ESX host. What was interesting is when power came back on 4 minutes later, none of the Virtual Machines failed back to the other server as we had them for load balancing.
I checked the configuration tab and under networking I selected the VSwitch with the VMs on it and the little weird box to the left when clicked did say Failback enabled on both ESX hosts.
How do I get failback working and is this actually a good idea or is it better to go in and manually move the VMs back?
Thanks in advance guys/gals
