Table 27. Event descriptions and recommended actions (continued)
Number Severity Description/Recommended actions
● If event 191 is not logged within 5 minutes after this event, the supercapacitor has probably
failed and the controller module should be replaced.
191 Info. The auto-write-through trigger event that caused event 190 to be logged has been resolved.
Recommended actions:
● No action is required.
192 Info. The controller module's temperature has exceeded the normal operating range.
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 193 is
logged to indicate that write-back mode has been restored.
Recommended actions:
● If event 193 has not been logged since this event was logged, the over-temperature
condition probably still exists and should be investigated. Another over-temperature event
was probably logged at approximately the same time as this event (such as event 39, 40,
168, 307, 469, 476, or 477). See the recommended actions for that event.
193 Info. The auto-write-through trigger event that caused event 192 to be logged has been resolved.
Recommended actions:
● No action is required.
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.
