Controller Critical Alerts - IBM BladeCenter S SAS RAID Controller Module Installation And User Manual

5101 • 1104
5101 Controller in survivor mode - Redundant controller controller_ID failed or missing
Explanation: The surviving controller generates this alert when the other controller is undetectable or unresponsive.
This alert occurs when the other controller is removed for service.
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 when the survivor rebinds.
Operator response: Insert the missing controller or replace the failed controller.
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
5102 Controller in survivor mode - Redundant controller controller_ID ready for removal
Explanation: The survivor controller generates this alert in conjunction with alert 2100 being generated by the other
controller.
System action: By default, the SAS RAID Module system information indicator is turned on and the operator is not
notified of this alert by e-mail. Alert clears when the other controller is removed or restarted.
Operator response: Remove or reboot the other controller.
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.

Controller critical alerts

The alerts in this section are generated when a critical failure has occurred.
1103 Controller critical failure detected - baseboard management controller failed
Explanation: The controller continually monitors the health of the Baseboard Management Controller subsystem and
controls the power for the controller. If this subsystem fails, the controller might not be able to control indicator
lights, check environmental conditions, store critical state information, and retrieve system identity data. When this
alert is generated, the controller can no longer continue normal operation.
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. If the failure occurs in a redundant controller, the remaining controller enters survivor
mode and assumes control of all disk drives and associated LUNs while the failed controller enters service mode. If
this failure occurs on a controller that is already in survivor mode, the controller attempts to flush all dirty cache and
orderly dismount all volumes prior to entering service mode.
Operator response: Reboot the controller. All alerts are cleared. The controller reevaluates the system health status
and regenerates all alerts that apply. If alert 1103 is generated again after the reboot, replace the controller. See
"Replacing a single controller using the CLI" on page 154 or "Replacing a single controller using the SCM" on page
155.
1104 Controller critical failure detected - SES/SAS expander failed
Explanation: The controller continually monitors the health of the SES (System Enclosure Services) controller / SAS
expander subsystem. If this subsystem fails, the controller might not be able to control indicator lights, check
environmental conditions, and access drives. When this alert is generated, the controller can no longer continue
normal operation.
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. If the failure occurs in a redundant controller, the remaining controller enters survivor
mode and assumes control of all disk drives and associated LUNs while the failed controller enters service mode. If
this failure occurs on a controller that is already in survivor mode, the controller attempts to flush all dirty cache and
orderly dismount all volumes prior to entering service mode.
Operator response: Reboot the controller. All alerts are cleared. The controller reevaluates the system health status
and regenerates all alerts that apply. If alert 1104 is generated again after the reboot, replace the controller. See
"Replacing a single controller using the CLI" on page 154 or "Replacing a single controller using the SCM" on page
155.
