8.3 Silencing Audible Alarms
An audible alarm indicates that either a component in the array has failed or a
specific controller event has occurred. Error conditions and controller events are
reported by event messages and event logs. Component failures are also indicated
by LED activity on the array.
Note – It is important to know the cause of the error condition because how you
silence the alarm depends on the cause of the alarm.
To silence the alarm, perform the following steps:
1. Check the error messages, event logs, and LED activity to determine the cause of
the alarm.
Component event messages include but are not limited to the following:
■ SES/PLD firmware mismatch
■ Temperature
■ Cooling element
■ Power supply
■ Battery
■ Fan
■ Voltage sensor
Caution – Be particularly careful to observe and rectify a temperature failure alarm.
If you detect this alarm, shut down the controller. Shut down the server as well if it
is actively performing I/O operations to the affected array. Otherwise, system
damage and data loss can occur.
See “Failed Component Alarm Codes” on page C-1 for more information about
component alarms.
Controller event messages include but are not limited to the following:
■ Controller
■ Memory
■ Parity
■ Drive SCSI Channel
■ Logical drive
■ Loop connection
Refer to the “Event Messages” appendix in the Sun StorEdge 3000 Family RAID
Firmware User’s Guide for more information about controller events.
