8-6 SANnet II 200 FC, SATA, and SATA SE Array Installation, Operation, and Service Manual March 2005
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 Appendix C 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 SANnet II Family RAID Firmware
Users Guide for more information about controller events.
