Table 27. Event descriptions and recommended actions (continued)
Number Severity Description/Recommended actions
This event will most commonly occur after a power loss if the real-time clock battery has failed.
The time may have been set to a time that is up to 5 minutes before the power loss occurred, or
it may have been reset to 1980-01-01 00:00:00.
Recommended actions:

C errors that may have been fully recovered.
Recommended actions:
● No action is required.
305 Info. A serial number in Storage Controller (SC) flash memory was found to be invalid when compared
to the serial number in the controller-module or midplane FRU ID SEEPROM. The valid serial
number has been recovered automatically.
Recommended actions:
● No action is required.
306 Info. The controller-module serial number in Storage Controller (SC) flash memory was found to be
invalid when compared to the serial number in the controller-module FRU ID SEEPROM. The
valid serial number has been recovered automatically.
Recommended actions:
● No action is required.
307 Critical A temperature sensor on a controller FRU detected an over-temperature condition that caused
the controller to shut down.
Recommended actions:
● Check that the storage system’s fans are running.
● Check that the ambient temperature is not too warm. The controller enclosure operating
range is 5°C to 35°C (41°F to 95°F). The expansion enclosure operating range is 5°C to
40°C (41°F to 104°F).
