ERROR_CLUSTER_GUM_NOT_LOCKER - 5085 (0x13DD)

Technical Meaning

The error code ERROR_CLUSTER_GUM_NOT_LOCKER with the numeric value 5085 and hexadecimal representation 0x13DD indicates that a non-locker component attempted to reserve the lock for performing global updates in a Windows cluster environment. This suggests an operational inconsistency or misconfiguration within the cluster management system.

Error Details

In a Windows cluster, certain operations require exclusive access to critical resources, which are managed through locking mechanisms. The locker component is responsible for managing these locks and ensuring that only one entity can perform global updates at any given time. When a non-locker code requests to reserve the lock, it indicates an unexpected situation where the system expects a locker operation but receives a request from another source.

Usage Context

This error typically occurs in scenarios involving cluster management operations such as failover, maintenance, or configuration changes that require exclusive access to shared resources. It is important for developers and administrators to understand this context when encountering this error.

Developer Interpretation

Developers should interpret this error code as an indication of a misconfiguration or operational inconsistency within the cluster environment. The presence of this error suggests that the system was expecting a locker operation but received a request from another source, which could be due to various factors such as incorrect usage context, invalid parameter values, or unexpected behavior in the cluster management components.

Related Errors

• ERROR_CLUSTER_INVALID_NODE (5091): Indicates an invalid node ID.
• ERROR_CLUSTER_RESOURCE_NAME_COLLISION (5084): Suggests a resource name collision during cluster operations.

FAQ

Q: What does the error code ERROR_CLUSTER_GUM_NOT_LOCKER mean?

A: It indicates that a non-locker component attempted to reserve the lock for making global updates in a Windows cluster environment.

Q: How can I troubleshoot this issue?

A: Review the operation context, validate parameters, and confirm object types. Ensure that all operations are performed by the correct components within the cluster management system.

Summary

The ERROR_CLUSTER_GUM_NOT_LOCKER error code is a generic indication of an operational inconsistency in a Windows cluster environment where a non-locker component attempted to reserve the lock for global updates. Developers should interpret this error as a sign of misconfiguration or unexpected behavior and take appropriate steps to resolve it.
