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?
