104 Events and event messages
Description/Recommended actions
Recommended actions:
• Restart the Storage Controller that logged this event.
• If this event is logged again, shut down the Storage Controller and replace the CompactFlash.
• If this event is logged again, shut down the Storage Controller and replace the controller module.
The auto-write-through trigger event that caused event 242 to be logged has been resolved.
Recommended actions:
• No action is required.
The controller module's CompactFlash card has failed.
This change met a condition to trigger the auto-write-through feature, which has disabled write-back cache
and put the system in write-through mode. When the fault is resolved, event 241 is logged to indicate that
write-back mode has been restored.
Recommended actions:
• If event 241 has not been logged since this event was logged, the CompactFlash probably does not have
health of OK and the cause should be investigated. Another CompactFlash event was probably logged at
approximately the same time as this event (such as event 239, 240, or 481). See the recommended
actions for that event.
A new controller enclosure has been detected. This happens when a controller module is moved from one
enclosure to another and the controller detects that the midplane WWN is different from the WWN it has in
its local flash.
Recommended actions:
• No action is required.
An existing disk channel target device is not responding to SCSI discovery commands.
Recommended actions:
• Check the indicated target device for bad hardware or bad cable, then initiate a rescan.
The coin battery is not present, is not properly seated, or has reached end-of-life.
The battery provides backup power for the real-time (date/time) clock. In the event of a power failure, the
date and time will revert to 1980-01-01 00:00:00.
Recommended actions:
• Replace the controller module that logged this event.
The FRU ID SEEPROM for the indicated field replaceable unit (FRU) cannot be read. FRU ID data might not
be programmed.
FRU ID data includes the worldwide name, serial numbers, firmware and hardware versions, branding
information, etc. This event is logged once each time a Storage Controller (SC) is started for each FRU that is
not programmed.
Recommended actions:
• Return the FRU to have its FRU ID data reprogrammed.
A valid feature license was successfully installed. See event 249 for details about each licensed feature.
Recommended actions:
• No action is required.
