An alarm triggered by an event might not reset to a normal state if vCenter Server does not retrieve the event that identifies the normal condition. In such cases, reset the alarm manually to return it to a normal state.


Launch the vSphere Client and log in to a vCenter Server system.

Required privilege: Alarm.Set Alarm Status


  1. Locate the triggered alarm in the Triggered Alarms panel or on the Alarms tab for the object.
  2. Right-click the alarm and select Reset Alarm to Green.
