Checking the FRU Data Integrity
The utility needs the FRU Common Header offsets to be correct. The utility checks the Common
Header Area in each NVS device against the FRU file and runs a checksum on it. If the Common
Header Area in the FRU file is correct and matches what is in the NVS device, then the information
is programmed. An incorrect Common Header means the FRU area is corrupted or has not been
initialized.
If the Internal Use Area of the BMC is loaded from the FRU file, then the BMC will be cold reset.
This allows the BMC to re-initializes its internal copy of the Internal Use area from the FRU. The
effect of re-initializing the Internal Use Area is that both the SDR table and the SEL (System Event
Log) table are cleared. All information in both areas is lost and the SDRs must be reprogrammed.
Updating the SDR Non-Volatile Storage Area
After the utility validates the header area of the supplied SDR file, then it updates the SDR
repository area. Before programming begins, the utility clears the SDR repository area. When
loading an SDR file from a Configuration File, the utility filters all tagged Sensor Data Records
using a list of tags determined by you, which represent the product’s configuration. Non-tagged
Sensor Data Records are automatically programmed.
After an update is successfully performed, a single message is displayed and the utility exits. If the
utility fails, then it exits with an error message and an exit code.
Updating the FRU Non-Volatile Storage Area
After the system configuration is determined, a typical configuration file updates the FRU
nonvolatile storage area. It will first verify the Common Header area and checksum from the
specified FRU file with what is programmed in the FRU nonvolatile storage device. If specified,
the Internal Use Area is then read out of the specified FRU file and is programmed into the
nonvolatile storage device. Then chassis, board, and product areas are read out of the specified
FRU file and programmed into the nonvolatile storage device. Lastly, the Multi-Record Area is
read out of the specified FRU file, and then the area is programmed into the FRU nonvolatile
storage device.
After an update is successfully performed, a single message is displayed and the utility exits. If the
utility fails, then it exits with an error message and an exit code.
