ERROR_CLUSTER_NODE_ALREADY_DOWN - 5062 (0x13C6)
The cluster node is already down.
Updated: Feb 21, 2026
Technical Meaning
The ERROR_CLUSTER_NODE_ALREADY_DOWN error indicates that a cluster node has been explicitly brought down or is already in the state of being unavailable. This status can be observed during operations such as node removal from a Windows Failover Cluster, where the system recognizes that the specified node is no longer operational.
Error Details
This error code is specific to the Windows Failover Clustering environment and is returned when an operation attempts to bring down or manage a node that is already in a down state. The cluster management APIs use this return value to inform the application of the current state of the node, ensuring that operations are performed only on nodes that are actually operational.
Usage Context
This error can be encountered in various scenarios within a Windows Failover Cluster environment, such as:
- Attempting to remove a node from the cluster when it is already down.
- Executing commands or operations that require a node to be up and running but find it in a down state.
Developer Interpretation
Developers should interpret this error code as an indication that the specified node is not available for the operation being attempted. This can occur due to various reasons, such as manual shutdown of the node or failure of the node's hardware components. Developers are advised to handle this error by ensuring that operations are only performed on nodes that are in a healthy and operational state.
Related Errors
ERROR_CLUSTER_NODE_NOT_FOUND(5061): Indicates that the specified node does not exist within the cluster.ERROR_CLUSTER_NODE_DOWN(5063): A generic error indicating that the node is down, but may be recoverable.ERROR_CLUSTER_NODE_UNREACHABLE(5074): The node cannot be contacted or reached for operations.
FAQ
Q: What does the ERROR_CLUSTER_NODE_ALREADY_DOWN error mean?
A: It indicates that the specified cluster node is already in a down state and cannot perform the requested operation.
Q: How can I handle this error in my application?
A: Ensure that your operations only proceed when nodes are confirmed to be operational. Check the current status of nodes before performing any critical operations.
Summary
The ERROR_CLUSTER_NODE_ALREADY_DOWN error is a specific return code used by Windows Failover Clustering APIs to indicate that an operation cannot be performed because the specified node is already down. Developers should handle this error by validating the operational state of cluster nodes before executing critical operations.
