Maintaining Your Array

7.2
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 terms:
■
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 and 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 terms:
■
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.
