Number Severity Description/Recommended actions
194 Info. The Storage Controller in the partner controller module is not up.
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 195 is logged
to indicate that write-back mode has been restored.
Recommended actions:
• If event 195 has not been logged since this event was logged, the other Storage Controller is probably still
down and the cause should be investigated. Other events were probably logged at approximately the same
time as this event. See the recommended actions for those events.
195 Info. The auto-write-through trigger event that caused event 194 to be logged has been resolved.
Recommended actions:
• No action is required.
198 Info. A power supply 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 199 is logged
to indicate that write-back mode has been restored.
Recommended actions:
• If event 199 has not been logged since this event was logged, the power supply probably does not have a
health of OK and the cause should be investigated. Another power-supply event was probably logged at
approximately the same time as this event (such as event 168). See the recommended actions for that
event.
199 Info. The auto-write-through trigger event that caused event 198 to be logged has been resolved.
Recommended actions:
• No action is required.
200 Info. 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.
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).
