Changing the Alarm Mute Setting
You can enable or disable the audible alarm that sounds when the controller becomes
too hot, detects low or high voltage, or an array becomes critical or offline. Changing
the mute setting lets you turn off the alarm when it is sounding. You should turn it
back on after resolving the problem.
The alarm sounds for temperature or voltage conditions (events). Warning events are
generated when the temperature or voltage enters the warning range. Shutdown
events are generated when the temperature or voltage enters the shutdown range.
After reaching the shutdown range, the controller will not function. You must resolve
the problem and reboot the controller. If the problem is not resolved, it will shut down
again.
Alarm conditions trigger an event message that displays in the Disk Array
Administrator software window and in the event log. See
Displaying the Event Log
on page 5-1.
Table 7-1 shows the temperature and voltage thresholds for each alarm and what to
do to resolve the problem.
