Working with Enclosure Alarms


	Note: Enclosure alarm support is based on the SES protocol. 9750 controllers support enclosure audio alarm for enclosures with expanders and I2C backplanes that support the SES-2 protocol. 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. Supported enclosures are listed at http://www.lsi.com/channel/support/marketing_resources, through the Data & Interoperability tab. Additional support information is available in the LSI KnowledgeBase, at this website: http://kb.lsi.com.

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 3DM2, 3BM, or the CLI. If the enclosure supports muting, you can also mute and unmute the alarm in 3DM2 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 3DM2 Alarms page. Status information about supported enclosures is also available on the 3DM2 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 3DM2 Enclosure Details page.
