Configuration File
A configuration file can be used by the FRUSDR utility. The configuration file is ASCII text and
editable. The file is parsed and pertinent information is stored internally by the utility. The
information obtained from the configuration file is used to direct the execution path of the utility
and to establish a configuration for the product. The configuration file allows you to override
values contained in an associated FRU file; it does not allow you to add areas to a FRU file. If you
leave out FRU areas or fields during programming, then the information already contained in those
FRU areas or fields on the server will remain.
The utility executes commands formed by the strings present in the configuration file. These
commands cause the utility to perform various tasks needed to ultimately load the proper Sensor
Data Records into the nonvolatile storage of the BMC and possibly generic FRU devices. Some of
the commands are user interactive.
Compare Command
The configuration file compare command allows the validation of information which exists in the
nonvolatile storage device without programming that information. The compare command is used
in a configuration file, and placed on the same line after the FRU or SDR name to be compared.
For the FRU, the compare functionality does a byte-by-byte comparison of the nonvolatile storage
device and what was to be programmed. The internal use area is never compared; this utility
considers all bytes of the internal use area to be dynamic and subject to change at will by the
firmware. In the board area, the manufacturing date and time, and the board area checksum are also
not compared, although the rest of the board area bytes are compared.
For the SDR, the compare feature does a byte-by-byte comparison of the nonvolatile storage device
and what was to be programmed. No checksum is used. During a comparison, the first two bytes
of each Sensor Data Record are ignored, because when the repository was programmed, the first
two SDR bytes were modified by the BMC and a pointer inserted.
