ERROR_CLUSTER_NETWORK_NOT_INTERNAL
The operation requires a network that the cluster can use for node-to-node communication, but the selected network has a client-only or otherwise incompatible role. Changing network roles without checking dependencies can disrupt the cluster.
Review the selected network’s role and the presence of alternative cluster communication networks before changing it. Promote a network to cluster communication only when its topology and operational intent support node-to-node traffic.
What to check
- Inspect the cluster network and its interfaces to determine which networks carry internal communication.
- Keep at least one healthy internal communication path between active nodes.
- Validate the design after changing network topology or adapter roles.
