This article explains how to silence a vSAN health check.
Q: When do I need to silence a vSAN health check?
In certain cases, you might want to ignore the results of certain health checks to avoid false alarms or known issues with your environment.
Q: What happens when a vSAN health check is silenced?
After you silence the health check, vSAN ignores that health check result and marks the health status as 'skipped'. It does not trigger any alarms. If a health check category contains only green and skipped health checks, the overall status of the category is green.
Note: We highly recommend extreme caution when silencing alerts as there is the potential for one to forget an alert is silenced and then forget to address the issue for which the alert has been silenced. It's best to not silence any alerts so the user can remember to address the issue sooner rather than later when it can potentially become a more serious problem.
Outside of temporarily silencing an alert to complete a cluster upgrade or another KB that says it's safe to silence an alert we would advise engaging VMware by Broadcom support for guidance before proceeding with silencing an alert.
