This display issue is fixed in SR 2.3. Once the battery on your Vtrak E-Class unit surpasses 44 degrees Celsius, this event will be generated in your runtime and nvram events being reported as “Unknown event - 0x10011”. When this happens your logical write disk cache (if adaptive write cache is enabled) will set to write through.
The the temperature reaches a normal state you will see “Unknown event - 0x10012" the logical write disk cache will be set to writeback
Note: Take corrective action (the temperature rising greater than 44 degrees Celsius), not doing so will affect your write performance. You can disable Adaptive write cache how ever your data in the logical write disk cache will not be protected by the battery pack in the event of a power outage.
