Error Handling
•
Most commands are retried four or more times. The firmware is programmed to provide
the best effort to recognize an error and recover from it if possible.
•
Failures are logged and stored in NVRAM. Operating system-based errors are viewable
from the event viewer in the Web Console 2.
•
RAID-related errors can be reported by the hard drive firmware, SAF-TE controller, or
the RAID controller firmware. These errors may be reported to the operating system
through RAID management software, through SMART monitoring, or through CIM
management. Some errors may also be reported by the SAF-TE controller and logged in
the system event log (SEL) for the Intel
®
server board. In addition, the operating system
may report access errors. Depending on the RAID controller and drive enclosure, the
error may be evident by the color of LEDs, the flashing of LEDs, or audible alarms.
Audible Alarm
The following list of beep tones is used on Intel
®
Intelligent RAID Controllers. These beeps
usually indicate that a drive has failed.
•
Degraded Array or Disk Group: Short tone, 1 second on, 1 second off
•
Failed Array or Disk Group: Long tone, 3 seconds on, 1 second off
•
Hot Spare Commissioned - Short tone, 1 second on, 3 seconds off
During a rebuild, the tone alarm stays on. After the rebuild completes, an alarm with a
different tone will sound.
The disable alarm option in either the Intel
®
RAID BIOS Console 2 or Intel
®
Web Console 2
management utilities holds the alarm disabled after a power cycle. You must use the enable
alarm option to re-enable the alarm.
The silence alarm option in either the Intel
®
RAID BIOS Console 2 or the Intel
®
Web
Console 2 management utilities will silence the alarm until a power cycle or another event
occurs.
