A vSphere HA failover occurs, and the virtual machine restarts.
Even when checking the Events of the specific virtual machine, the event "vSphere HA initiated a failover action" (which indicates the initiation of the HA failover) cannot be found.
This behavior is by design. The event "vSphere HA initiated a failover action" (com.vmware.vc.HA.ClusterFailoverActionInitiatedEvent) is triggered at the Cluster object level. Therefore, it is not recorded in the event logs of individual Virtual Machine objects.
To verify this event, please check the event log at the cluster level by navigating to:
[Cluster] > [Monitor] > [Tasks and Events] > [Events]
On the virtual machine side, only events specific to that VM are recorded, such as "vSphere HA restarted a virtual machine" (com.vmware.vc.ha.VmRestartedByHAEvent), which indicates that the restart has completed.
