HP P2000 G3 MSA System Event Descriptions Reference Guide 29
188
Info. Write-back cache has been disabled.
Event 187 is the corresponding even that is logged when write-back cache is disabled.
Recommended actions
• No action is required.
189
Info. A disk channel that was previously degraded or failed is now healthy.
Recommended actions
• No action is required.
190
Info The controller module's super-capacitor 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 super-capacitor 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.
