C-20 Emergency Management Port
FRU & SDR Load Utility, Version 2.0, Revision X.XX
where X.XX is the revision number for the utility.
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
might 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.
