76 Configuration Software and Utilities
Configuration File
The configuration file is in ASCII text. The utility executes commands formed by the strings
present in the configuration file. These commands cause the utility to run tasks needed to load the
proper SDRs into the nonvolatile storage of the BMC and possibly generic FRU devices. Some of
the commands may be interactive and require you to make a choice.
Prompting for Product Level FRU Information
Through the use of a configuration file, the utility might prompt you for FRU information.
Filtering Records From the SDR File
The MASTER.SDR file has all the possible SDRs for the system. These records will probably
need to be filtered based on the current product configuration. The configuration file directs the
filtering of the SDRs.
Updating the SDR Nonvolatile Storage Area
After the utility validates the header area of the supplied SDR file, it updates the SDR repository
area. Before programming, the utility clears the SDR repository area. The utility filters all tagged
SDRs depending on the product configuration set in the configuration file. Nontagged SDRs are
automatically programmed. The utility also copies all written SDRs to the SDR.TMP file; it
contains an image of what was loaded. The TMP file is also useful for debugging the server.
Updating FRU Nonvolatile Storage Area
After the configuration is determined, the utility updates the FRU nonvolatile storage area. First it
verifies the common header area and checksum from the specified FRU file. The internal use area
is read out of the specified .FRU file and is programmed into the nonvolatile storage. The chassis
area is read out of the specified .FRU file. Finally, it reads the product area out of the specified
FRU file, then the area is programmed into the FRU nonvolatile storage. All areas are also written
to the FRU.TMP file.
Updating DMI FRU Nonvolatile Storage Area
After programming the BMC FRU area, the utility programs chassis, board, and product
FRU information to the DMI fields, if the DMI flag follows each FRUAREA command in the
configuration file.
Cleaning Up and Exiting
If an update was successfully performed, the utility displays a single message and then exits.
If the utility fails, it immediately exits with an error message and exit code.
