Hyper-V stand alone to cluster

Hello,

I have a stand alone Hyper-V server, VMs are located on a storage on a iSCSI shared disk.
Now I have another server to add as an Hyper-V new node, so the idea is to configure Hyper-V fail over cluster.

It's possible to "migrate/install" the actual stand alone Hyper-V production node to the new scenario using the same iSCSI shared disk ?

Can load the VMs load over the 2 nodes ?

Thanks.

Yes it is possible.
You need to install failover cluster and add the storage as CSV.
Then move your VMs to the hyper-v cluster.

Please configure Livemigration as well.

I can use the actual iSCSI shared to use as CSV or must be a new (empty) one ?

Can you see the volumes in Failover Cluster Manager as available storage on both nodes?
If yes you can add safely without data loss.

I don't have yet configured Failover Cluster Manager, so my idea is to "convert" the shred LUN to CSV, but if there is any loss data risk I'll better create a new volume the migrate de VMs.

Thanks.

Does the iSCSI target support Shared LUNs? That is, it will allow multiple Hyper-V servers to connect to the same LUN?

If yes, then configure the second node identically to the first. If the CPU architecture is different then make sure to enable CPU compatibility mode on all of the VMs.

Once the two are set up, Cluster Role is installed, run the Cluster Validation Wizard in Failover Cluster Manager (FCM). Address anything that may arise in the report.

Once the cluster is formed, make sure to give the newly created Cluster Name Object (CNO) that is created in the same OU as the Hyper-V hosts Create Computer on the OU's permissions.

You can then use FCM to set the shared storage as Cluster Shared Volume(s) and finally configure Live Migration under the Network node.

Then, in FCM, add a Highly Available VM from the host it currently resides on.

Run a Live Migration to the new node. Then run one back to make sure LM works both ways.

Continue to HA the rest of the VMs and distribute them accordingly.
