Hi we have 3 hyper-v nodes (enteprise core) all connected to a SAN and using CSV for shared area for virtual machine config and hard disks. We have tested Live Migration and it moves from one node to another (taking approx 30 seconds). However LM aside in a non controlled way how should the failover work?
My understanding of LM is that the physical running RAM is synced to the other node so that it can take other however in the event of a physical failure this could not happen and the server taking over the VM would not have any RAM contents.
How should/does this work please?
