82 Events and event messages
Description/Recommended actions
A fan has failed.
This indicates that a trigger condition has occurred that has caused the auto-write-through feature to disable
write-back cache and put the system in write-through mode. When the fault is resolved, event 201 is logged
to indicate that write-back mode has been restored.
Recommended actions:
• If event 201 has not been logged since this event was logged, the fan probably does not have a health of
OK and the cause should be investigated. Another fan event was probably logged at approximately the
same time as this event (such as event 168). See the recommended actions for that event.
The auto-write-through trigger event that caused event 200 to be logged has been resolved.
Recommended actions:
• No action is required.
An auto-write-through trigger condition has been cleared, causing write-back cache to be re-enabled. The
environmental change is also logged at approximately the same time as this event (event 191, 193, 195, 199,
201, and 241.)
Recommended actions:
• No action is required.
An environmental change occurred that allows write-back cache to be enabled, but the auto-write-back
preference is not set. The environmental change is also logged at approximately the same time as this event
(event 191, 193, 195, 199, 201, or 241).
Recommended actions:
• Manually enable write-back cache.
An error occurred with either the NV device itself or the transport mechanism. The system may attempt to
recover itself.
The CompactFlash card is used for backing up unwritten cache data when a controller goes down
unexpectedly, such as when a power failure occurs. This event is generated when the Storage Controller
(SC) detects a problem with the CompactFlash as it is booting up.
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 system has started and found an issue with the NV device. The system will attempt to recover itself.
