STATUS_CLUSTER_NETINTERFACE_EXISTS
The cluster already contains that network interface
STATUS_CLUSTER_NETINTERFACE_EXISTS indicates that the requested network-interface object is already present in cluster configuration. A cluster network interface represents a node-specific adapter relationship, so this status is more granular than a duplicate network object.
Inspect the existing interface before trying to recreate it. Repeating an add-style operation cannot correct an address, driver, role, or link problem on an object that already exists; it only obscures the distinction between identity and health.
What to verify
- List interfaces by node and network with
Get-ClusterNetworkInterface. - Verify the adapter identity and the cluster network it belongs to.
- Run validation after driver, VLAN, or addressing changes.
