HP MSA Events Description Reference Guide (762785-001, March 2014)

Event descriptions 27
190
Info. The controller module's supercapacitor pack has started charging.
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 191 is logged to
indicate that write-back mode has been restored.
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.
