System enclosure alerts
The alerts in this section are related to the system enclosure housing the redundant
SAS RAID controller modules.
4001
System enclosure
enclosure_ID
product data memory inaccessible
Explanation:
The controller cannot read or write data to the nonvolatile memory device associated with each system
enclosure. This device contains vital configuration data and system identification necessary for normal functioning of
the system. In the system enclosure, the memory device is located in the media tray and is accessed by the RAID
controller via its onboard Baseboard Management Controller subsystem.
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. The alert clears when the media tray becomes functional or when the controller is
rebooted.
Operator response:
1.
If either controller has active alerts indicating a failure in the Baseboard Management Controller subsystem,
perform the associated diagnosis procedure for those alerts.
2.
If alert 4001 is active after other alerts are cleared, remove and reinsert the media tray. Doing so might clear the
alert.
3.
If the alert persists, replace the media tray (see “Replacing a media tray” on page 162).
Note:
The media tray contains information unique to each system, and must be configured specifically to replace
the previous media tray. Failure to use a preconfigured media tray intended for the target system might result in
additional system errors, including potential indeterminate data loss.
4.
If the alert persists, replace the controller. If doing so does not resolve the alert, reinstall the original controller.
5.
If the problem still persists, the blade chassis might be the cause.
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
5000
Controller warning - temperature out of range
Explanation:
Elevated temperature has been detected in the controller generating the active alert.
System action:
By default, the SAS RAID Module system information indicator is not turned on and the operator is
notified of this alert by e-mail. The controller continues normal operation unless the temperature climbs to a critical
level. The alert clears automatically when the temperature of the controller falls below the warning level threshold.
Operator response:
1.
Make sure the room environment is within specification for the Blade Center. Check the fans used to cool the
controller to see if they are operating correctly.
2.
If no cooling problem exists, the temperature sensor in the controller might be malfunctioning. 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.
This alert can be masked so that it does not trigger the SAS RAID Module system information indicator.
