vSAN health alarms are suppressed

Jump to solution

I have this warning for several of my vSAN clusters, but can't figure out what have been suppressed.

I've tried to use RVC to check why we have this alarm. No matter which of the 5 vSAN clusters I check RVC reports no alarms with Silent status other than Normal.

Anyone else seen this issue? Are there other alarms than those in RVC's vsan.health.silent_health_check_status causing this issue?

Hello Lars,

"Are there other alarms than those in RVC's vsan.health.silent_health_check_status causing this issue?"

No, they should be all there.

"Anyone else seen this issue?"

From reviewing this internally it appears to be a known issue which our engineering teams are aware of and working on resolving in a future release, I unfortunately can not currently provide a date/release in which it will be resolved - I will aim to create/delegate creation of some external documentation regarding this but for now it is safe to acknowledge/silence this alarm.

We also have this same alarm on one of our new vSAN clusters running vCenter 6.7.0 (14070654). I am able to acknowledge the alert but is there a way of restoring/enabling the vSAN related alarms?

At present if an issue such as a disk failure occurs this does not trigger and alarm, the issue is only visible if you access the vSAN Health page.

Edit 01/08/19

I now have a workaround/fix for this one. This alert appears when the quickstart wizard is in progress/not complete. Go to "Cluster > Configure > Configuration > Quickstart > Skip Quickstart". This cleared the alarm for me and enabled the vSAN health alarms.

Thanks alot, Jason.

Skip Quickstart really did the trick.
