Number Severity Description/Recommended actions
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.
201 Info. The auto-write-through trigger event that caused event 200 to be logged has been resolved.
Recommended actions:
● No action is required.
202 Info. 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.
203 Warning 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.

attempt to recover itself.

● If this event is logged again, shut down the Storage Controller and replace the
CompactFlash.

module.
