Audible Alarm
An 80db audible alarm, which is controlled by the RAID firmware, is mounted on the
RAID controller to indicate any of the following events:
•
State of controller upon boot-up
•
Change in the normal state of the array
•
Change of controller environmental status (during normal operation)
•
Failure of hardware that the controller manages
If the cause of the event is resolved and/or removed, the audible alarm will cease. You can
also turn off the audible alarm manually through StorCon or StorCon+. If you use these
management tools to silence the alarm, it will only be disabled for the current event and
will be ready to sound again at the next event.
