PowerStore: Pre-Upgrade Health Check (PUHC) Configured NVMe/TCP IO Queue Per Node Exceed Recommended Limit
요약: This health check validates that the configured NVMe/TCP I/O queue count is within the recommended limit for upgrade readiness. The check compares the current NVMe/TCP I/O queue count against the recommended maximum of 25,000 queues. ...

증상
High queue counts that significantly exceed 25,000 queues per node can increase the risk of upgrade disruptions and can cause temporary service availability issues in environments using NVMe/TCP connectivity.
The health check result is reported as Failed when the detected queue count exceeds 25,000.
원인
An internal software module may unexpectedly restart during the NVMe/TCP controller cleanup process in the Non-Disruptive Upgrade (NDU) workflow, resulting in NDU failure

해결
- Review the NVMe/TCP environment and determine whether the total configured NVMe/TCP I/O queue count exceeds the recommended limit of 25,000.
- If the queue count exceeds the recommended threshold, reduce the number of NVMe/TCP I/O queues by following the applicable host operating system and NVMe/TCP configuration guidelines.
- After the configuration changes have been applied, allow the changes to take effect and rerun the health check to verify that the queue count is within the recommended range.
