Working with Enclosure Alarms
Some enclosures provide an alarm that turns on when a RAID unit becomes
degraded or goes offline, or when a drive has failed. (Specific use of the alarm
feature may vary somewhat, depending on the enclosure.)
If you have an enclosure with an audio alarm, you can turn the alarm Off
when it sounds, using 3DM 2, 3BM, or the CLI. If the enclosure supports
muting, you can also mute and unmute the alarm in 3DM 2 or the CLI.
Note that you cannot turn an enclosure alarm on. Alarms are only turned on
(activated) when an error condition has been detected for a drive or RAID
unit. To view any error conditions that may have caused the enclosure alarm
to go off, see the
3DM 2 Alarms page. Status information about supported
enclosures is also available on the 3DM 2 Enclosure Details page. (You can
also use the CLI /cx show alarms command, or check the status of the RAID
unit in 3BM.)
Muting an alarm provides the ability to silence the alarm, without turning it
off completely. You can also set the alarm to Mute in advance, if you do not
want the alarm to sound. When the alarm audibility is set to
Mute and the
alarm turns on, the word Activated continues to display in the Status column
of the Audio Alarm Summary on the 3DM 2 Enclosure Details page, as
shown in Figure 9.
Note: Enclosure alarm support is based on the SES protocol.
9690SA controllers support enclosure audio alarm for enclosures with expanders
and I 2 C backplanes that support the SES-2 protocol, while 9650SE controllers
support enclosure audio alarms for SES I 2 C backplanes.
However, enclosure alarm support depends on the capabilities of the specific
enclosure or backplane. Not all enclosures provide an audio alarm, and for those
that do, not all provide both the On/Off and Mute/Unmute feature.
For details about what specific features are provided with your enclosure, see the
documentation that came with the enclosure or backplane.
Tip: Be sure you have the most recent firmware for the enclosure. If the alarm
feature does not work as anticipated, contact the manufacturer for updated
firmware.
