Cluster configuration fails if there is a conflict between the cluster private network and any other network

The NetBackup Flex Scale cluster uses a private network for inter-node communication and this network should not be reachable or pingable from the nodes outside the cluster. The subnet used for the private network should not conflict with the IP address of any other node. Even if a second NetBackup Flex Scale cluster is present in the data center, it should not be reachable using the private network. (IA-22967)
