This post discuss on how to fix an ‘Unsupported Cluster Configuration’ status when it’s caused by a configuration issue with the virtual networks. There’re a number of reasons a Virtual Machine (VM) can fall into a status of ‘Unsupported Cluster Configuration.’ A brief list from TechNet, shows that storage, networking, and other factors can cause this status:
-The virtual machine is on a LUN that contains more than one virtual machine.
-The virtual machine is using non-clustered storage.
-One or more virtual network adapters on the virtual machine are not connected to a highly available virtual network.
-An ISO image is attached to highly available virtual machines.
-A VMware HAVM is connected to a port group that does not exist on all nodes of the host cluster.
