Hyper-V 2019 Standard VM's vanished after power outage.

I have installed a failover cluster, using shared iscsi storage & migrated 5 virtual servers to it from an older server 2012 Hyper-V. After the power went out, none of the VM's are even listed in the Hyper-V manager on the new system. This has been in place & running for about 2 months.

I am able to browse to the .vhdx files, what is the best method for bringing them back in & getting them online.

Where are the configuration files for the VMs?

Are the volumes set up as Cluster Shared Volumes?

Do the VMs show up in Hyper-V Manager on each node as opposed to Failover Cluster Manager?

Is there a UPS in place that can gracefully shut down the VMs, then pause and drain one node, and finally shut down the cluster service then the last node standing? <-- This is the proper order of things in this situation.

Since separate storage is involved, does the storage setup have a graceful shutdown set up as well?

Now that the external storage is booted, have you tried rebooting both hosts so they can connect to the storage properly? It is possible in the event of power outage that the servers boot faster than the storage can come online.

The VMs should always show up in the owner node's Hyper-V Manager thus the question. The next step when they don't is to import them thus the question about the configuration files location.
