ERROR_HOST_NODE_NOT_AVAILABLE
The requested host node cannot currently service the resource
A cluster node is a distinct managed object with its own state. Resource placement can fail before the resource DLL is called when the designated host is down, paused, leaving membership, or otherwise unavailable to the active cluster.
This code should be distinguished from ERROR_NODE_CANT_HOST_RESOURCE. Here the immediate problem is node availability; it does not by itself prove that the resource is incompatible with the node. Verify node state and membership first.
What to inspect
- Query all nodes and compare the requested node with the current owner and possible-owner list.
- Check Cluster Service and membership events on the unavailable node, including recent pause, drain, restart, or communication loss.
- If this is a planned move, choose another eligible online node instead of repeatedly targeting a node that is not participating normally.
