ERROR_CLUSTER_NETWORK_NOT_INTERNAL - 5060 (0x13C4)

Technical Background

This error code, ERROR_CLUSTER_NETWORK_NOT_INTERNAL with the numeric value 5060 and hexadecimal representation 0x13C4, indicates that a network configuration issue exists within a Windows Failover Cluster. Specifically, it signifies that one or more network interfaces are not configured to support internal cluster communication.

Error Details

In a failover cluster environment, nodes communicate with each other using both public and private networks. The private network is used for internal cluster communication, ensuring high-speed and reliable data exchange among the cluster members. If a network interface is not properly configured as part of this private network, the cluster will encounter issues in maintaining its operational integrity.

Common Causes

• Incorrect Network Interface Configuration: A network interface may be incorrectly assigned to the public network instead of the private network.
• Misconfigured Cluster Network Settings: The cluster network settings might not have been correctly configured during setup or subsequent changes.
• Cluster Node Reconfiguration: After a node has been reconfigured, the network interfaces need to be reassigned to ensure proper communication.

Real-World Context

In a typical failover cluster scenario, nodes must communicate with each other for various operations such as resource management, quorum decisions, and data synchronization. The ERROR_CLUSTER_NETWORK_NOT_INTERNAL error can disrupt these processes if not addressed promptly.

Is This Error Critical?

Yes, this error is critical because it directly impacts the internal communication within the cluster. Without proper internal network configuration, the cluster may fail to function correctly, leading to potential service disruptions or failures.

How to Diagnose

1. Review Network Configuration: Verify that all network interfaces are correctly assigned to the private network.
2. Check Cluster Network Settings: Ensure that the cluster network settings are properly configured and consistent across all nodes.
3. Validate Node Reconfiguration: If a node has been reconfigured, confirm that its network interfaces have been reassigned appropriately.

How to Resolve

1. Correct Parameter Usage: Ensure that all network interfaces are correctly assigned to the private network during initial setup or configuration changes.
2. Adjust Operation Context: Verify and adjust any cluster-related operations to ensure they align with the correct network configurations.
3. Restore Data: If necessary, restore data from a known good state to ensure consistency in the cluster environment.

Developer Notes

Developers should be aware that this error can occur due to misconfiguration during setup or changes made after initial deployment. Proper documentation and testing of network configurations are crucial to avoid such issues.

Related Errors

• ERROR_CLUSTER_INVALID_NODE (0x8024D013): Indicates an invalid node in the cluster.
• ERROR_CLUSTER_NOT_FOUND (0x8024D015): The specified cluster was not found on the local system or network.

FAQ

Q: What does the ERROR_CLUSTER_NETWORK_NOT_INTERNAL error mean?

A: This error indicates that a network interface is not configured for internal cluster communication, which can disrupt the cluster's ability to function properly.

Q: How do I resolve this issue?

A: Ensure all network interfaces are correctly assigned to the private network and verify that cluster settings are consistent across all nodes. Adjust configurations as necessary.

Summary

The ERROR_CLUSTER_NETWORK_NOT_INTERNAL error is a specific indication of misconfigured network interfaces in a Windows Failover Cluster environment. Proper configuration and validation of network settings are essential for maintaining the integrity and reliability of the cluster's internal communication. Developers should take proactive steps to ensure correct setup and ongoing maintenance to avoid this issue.
