I’ve seen a lot of Hyper-V clusters during my daily work. Most of the time, I see a mixture of none standardised names or letters. Also a mixture of upper and lower case names.
There’s is only one option to have all your cluster nodes in Upper case names within the failover cluster manager, you’ll have to use the command line! For example:
cluster.exe /cluster:<name of the cluster> /add /node:<name of the node in UPPER case>
For this command to work, you’ve to install ‘Failover Cluster Command Interface’.
