STATUS_CLUSTER_NETWORK_ALREADY_ONLINE
The cluster network is already Online
STATUS_CLUSTER_NETWORK_ALREADY_ONLINE says that a request to place a cluster network online has no state change to perform. It is not a promise that every network interface is healthy or that every node can communicate across that network.
Use the status as an idempotency result and inspect the network object plus its member interfaces. A network can be Online while one interface is down, excluded, or misconfigured, so automation should avoid treating this code as an end-to-end connectivity check.
What to verify
- List the network and its role with
Get-ClusterNetwork. - Inspect the node-specific interfaces associated with it.
- Use validation when a configuration change is expected rather than repeatedly requesting Online.
