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). Recommended actions • Manually enable write-back cache. 28 Event descriptions

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.
