Active/standby will be triggered upon resource exceptions. When this alarm is generated, the active/standby switchover is complete and new AOS resources have been enabled on the new active Manager. In this case, this alarm is cleared. This alarm is used to notify users of the cause of the active/standby Manager switchover.</p>
