ERROR_SHUTDOWN_CLUSTER

The cluster is being shut down.

Troubleshooting steps

• Record shutdown initiator and reason.
• Record node states and quorum state.
• Record active clustered roles and drain status.
• Record cluster log around shutdown start.

What to verify

Verify whether the cluster service is intentionally shutting down and cannot accept the requested operation. Check shutdown initiator and reason together with node states and quorum state.

Handling, retry, and recovery

Allow shutdown to complete, then reconnect to the restarted cluster; do not attempt configuration writes during teardown.
