Node is already registered in the cluster with management IP=10.30.156.120

Make subscriber failed
Cause : If we clone the VM instance on ESX and provision the cloned instance as new CPPM server, it copies the UUID as well, thus the cloned and original Clearpass VM both have the same UUID and we cannot join the nodes to the same cluster.
