Audible Alarm Definitions for Intel® RAID Controllers

The Intel® RAID Controller audible alarm beeps when a drive fails and also during a rebuild.

What are the different alarm beeps for drive failures?

1. Degraded array: Short tone, one second on, one second off
   • Array has degraded, but no data has been lost.
2. Failed array: Long tone, three seconds on, one second off
   • Array has failed, and high likelihood that data has been lost.
3. Hot spare commissioned: Short tone, one second on, three seconds off
   • Using hot spare in rebuild; alarm continues during rebuild with a different sound at completion. See also How to Stop Your Intel® RAID Controller from Continuing to Beep After Rebuild Is Complete for more information.

The drive failure tones repeat until:

• The problem is corrected.

• The alarm is silenced or disabled.

You can silence or disable the alarm:

• On the controller’s properties page in the BIOS Console

• By using the failed drive options pane in the Intel® RAID Web Console 2
