The cluster node is up.
Updated: Feb 21, 2026
Technical Meaning
The error code ERROR_CLUSTER_NODE_UP with the numeric value 5056 and hexadecimal representation 0x13C0 is returned when a cluster node transitions to an up state. This indicates that the node has successfully joined or re-joined the cluster and is now operational.
Error Details
This error code is typically used in scenarios where the system needs to communicate the status change of a cluster node. It does not indicate any failure but rather a successful transition from a down state to an up state, ensuring that the node can participate in cluster operations such as failover and resource management.
Usage Context
The error code is relevant in environments utilizing Windows Failover Clustering (FCM) or other clustering technologies. It may be encountered during the initialization of a cluster, following a node failure recovery, or when a new node is added to an existing cluster.
Developer Interpretation
When this error code is returned, it signifies that the system has successfully transitioned a cluster node from a down state to an up state. Developers should interpret this as a positive outcome and not indicative of any failure. The node can now be considered operational within the cluster environment.

FAQ
Q: What does the error code ERROR_CLUSTER_NODE_UP indicate?
A: It indicates that a cluster node has successfully transitioned from a down state to an up state, and is now operational within the cluster environment.
Q: Is this error critical?
A: No, it is not a critical error. The system operation is proceeding as expected with the node now in an up state.
Summary
