Using Onboard Failure Logging
Onboard Failure Logging (OBFL) collects and stores boot, environmental, and critical hardware data in the
nonvolatile flash memory of the CPU controller card. This information is used for troubleshooting, testing,
and diagnosis if a failure or other error occurs. This data provides improved accuracy in hardware
troubleshooting and root cause isolation analysis. The data collected includes field-replaceable unit (FRU)
serial number, OS version, total run time, boot status, temperature and voltage at boot, temperature and voltage
history, and other board specific errors.
