Yes, if the Host fails due to a power outage, or uncontrolled shutdown e.g. pull the power out of the Node to Test.

Ok - I will check on that as well. This is interesting as well. When I go to migrate some VMs, why do I see a transfer type of Network and others I see a transfer type of Cluster? All the VMs that I am trying to transfer are from the same host server, they are all going to the same destination server (apart of the same cluster), and they are all powered off. Any ideas? Could this be related?

Edit:  I did check to make sure the VMs are marked as High Availability, and some of them are set to HA, and others are grayed out with the box unchecked.

Those VMs for which you are getting greyed out checkbox, they were placed out of CSV volume and causing they can't be make highly available

Can you check setting of each VM and check VHD \VHDX path where its locating ?

The path must be %systemroot%\ClusterStorage\Volume1\..........

Also CSV volume must be present on all clustered hyper-v nodes

If path is different, then the VM is not highly available

If path does not exists, then you don't have CSV volume enabled for attached shared storage

Thank you for the help!
