I’m publishing this article because I ran into the issue lately.

I created an Hyper-V Cluster with 3 Nodes, lets say :

  • HYPERV-01
  • HYPERV-02
  • HYPERV-03

You noticed I used uppercase letters.

In the Failover Cluster, I can see all the nodes as I added them in uppercase letters.

For some reason, I had to remove one node from the cluster and when I added it again using the wizard the name of the node was this one :

  • hyperv-03

So after some research, I found out that using the cluster command I could define correctly my node name in the cluster.

To do so, just open Windows Powershell with all modules and enter the following command :

cluster.exe /cluster:CLUSTER-NAME /add /node:HYPERV-03

I hope this helps.
