Instructions
From vSAN 6.6, a new feature was introduced; which enables administrators to manually suppress or express each result of vSAN health check using Ruby vSphere Console(RVC).
We can take advantage of the feature when a customer does not want expected alarms to appear on UI.
If vCenter does not have Internet access, the following alert appears:
-vSAN Build Recommendation Engine Health Alarm due to no Internet access.
CAUTION: By following this procedure, You are partially disabling the feature of vSAN health test. Ensure the cause of the alarm or warning which is being suppressed. If you are not confident, call VxRail Support.
-Procedure
- SSH to vCenter Server Appliance
- On vCenter Server Appliance, log in to the Ruby vSphere Console
# rvc Install the "ffi" gem for better tab completion. Host to connect to (user@host): administrator@vsphere.local@localhost password: < Supply vCenter SSO Password. 0 / 1 localhost/ >
- Verify Health Check ID and Silent Status of the target material, in this example, it is "vSAN Build Recommendation Engine Health." Take a note of its ID "vumconfig".

- Set the target material "Silent."

- Redo step 3 and check the silent status of the target material.

| vSAN Build Recommendation Engine Health | vumconfig | Silent |
| vSAN build recommendation | vumrecommendation | Normal |
+---------------------------------------------------------------------------------------------+-------------------------------------+---------------+
- On vSphere Web Client, perform the vSAN health check and verify that the target result is skipped.
Now you can Acknowledge or Reset the corresponding alarm on vSphere Web Client to green.
Additional Information
-If you think twice and want to re-enable vSAN health check results. Unset the silent status as following.vsan.health.silent_health_check_configure -r [Health Check Id] < Path to a ClusterComputeResource>
-For more details, check VMware KB 2151813.
Silencing a vSAN health check (2151813)
-In vSAN 6.6, these health checks are available.
