Number Severity Description/Recommended actions
302 Info. DDR memory clock frequency has changed to high.
Recommended actions:
● No action is required.
303 Info. DDR memory clock frequency has changed to low.
Recommended actions:
● No action is required.
304 Info. The controller has detected I
2
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).
● Check for any obstructions to the airflow.
● Check that there is a module or blank plate in every module slot in the enclosure.
If the problem persists, replace the controller module that logged the error.
309 Info. Normally when the Management Controller (MC) is started, the IP data is obtained from the
midplane FRU ID SEEPROM where it is persisted. If the system is unable to write it to the
SEEPROM the last time it changed, a flag is set in flash memory. This flag is checked during
startup, and if set, this event is logged and the IP data that is in flash memory is used. The only
time that this would not be the correct IP data would be if the controller module was swapped
and then whatever data are in the controller’s flash memory is used.
Recommended actions:
● No action is required.
310 Info. After a rescan, back-end discovery and initialization of data for at least one EMP (Enclosure
Management Processor) has completed. This event is not logged again when processing
completes for other EMPs in the system.
Recommended actions:
● No action is required.
311 Info. This event is logged when a user initiates a ping of a host using the iSCSI interface.
