ERROR_CLUSTER_NODE_ALREADY_DOWN
A stop or offline operation targeted a node that the cluster already considers Down. The next step is not another stop request; it is identifying why the node went down and whether the cluster still has quorum.
Check the first event that marked the node Down and verify quorum on the surviving members. Recovery should address that loss of membership or connectivity rather than repeatedly asking Cluster service to stop an already-down node.
What to check
- Confirm membership state and the time when the node transitioned to Down.
- Review cluster logs and System events for service shutdown, communications failure, or operating-system restart.
- Check quorum before attempting node recovery, especially in a small cluster.
