ERROR_NODE_CANT_HOST_RESOURCE

The node is alive but is not a valid host for this resource

This code differs from node-unavailable errors. Cluster placement reached a node that is participating, but the resource cannot be brought online there. Possible-owner restrictions, missing local prerequisites, storage visibility, installed software, or a resource DLL decision can make a node unsuitable.

The fastest comparison is between a node where the resource works and the rejected node. Resource type registration and private parameters are cluster configuration, but the resource implementation can still depend on node-local binaries, services, devices, or paths.

What to inspect

Check the resource possible-owner list and do not assume every cluster node is eligible.
Compare installed resource DLL components and resource-specific prerequisites across eligible nodes.
For storage or network resources, verify the node can see the required storage path or cluster network before forcing ownership.
