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:
■
Temperature
■
Cooling element
■
Power supply

Caution –
Be 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 Appendix C for more information about component alarms.
Controller event messages include but are not limited to the following terms:
■
