Controller warning alerts
The alerts in this section are generated as controller state warning messages.
0102 Controller in survivor mode - Redundant controller controller_ID is offline
Explanation: In a redundant controller system, if one controller enters service mode and the other survivor
controller assumes ownership of all LUNs, the surviving operational controller generates this alert. This alert is
generated as part of the normal concurrent controller replacement procedure.
System action: By default, the SAS RAID Module system information indicator is turned on and the operator is
notified of this alert by e-mail. Alert clears automatically after 120 seconds. The condition is resolved when the
controller rebinds.
Operator response:
Acknowledge to clear the alert immediately. Insert the other controller or diagnose the health of
the other controller by evaluating the active alerts for that controller.
1100 Controller non-critical failure detected - Ethernet port port_ID failed
Explanation: The controller Ethernet port is not functioning properly. Generally, this alert can be reported only
when two controllers are operating in a bound configuration and the user administrative interface (CLI or GUI) is
connected to the other controller.
System action: By default, the SAS RAID Module system information indicator is turned on and the operator is
notified of this alert by e-mail. The alert clears when the controller is rebooted. The controller with the failed Ethernet
port can continue to provide redundancy to the system and service host I/O requests. However, if the controller with
the working Ethernet port fails and the other controller becomes survivor, you will have no administrative
communication path with the system.
Operator response: Replace the controller reporting this alert. See “Replacing a single controller using the CLI” on
page 154 or “Replacing a single controller using the SCM” on page 155.
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
1101 Controller non-critical failure detected - RTC battery failed
Explanation: The controller real time clock (RTC) battery is not functioning properly.
System action: By default, the SAS RAID Module system information indicator is turned on and the operator is
notified of this alert by e-mail. The alert clears when the controller is rebooted. The controller with the failed RTC
battery can continue to provide redundancy to the system and service host I/O requests. However, if the other
controller fails and this controller becomes survivor, the system time might be reported incorrectly.
Operator response:
Replace the controller reporting this alert. See “Replacing a single controller using the CLI” on
page 154 or “Replacing a single controller using the SCM” on page 155.
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
