Hi ,
To clear the same follow the below steps
:
- Open vCenter Server using vSphere Client.
- In the vCenter inventory, select the ESX/ESXi host.
- Click the Hardware Status tab.
- Click System Eventlog under View and click the Reset Event log option. The red alert is removed from the System Event log.
- Click the Reset Sensors option to reset the host sensors.
If you are unable to clear please restart watchdog service(/etc/init.d/sfcbd-watchdog restart) if the host is ESX ,if its ESXi you can restart management agent
