header checksum. If the header checksum is incorrect, then a message will be
displayed indicating so.
Comparing the FRU File
The configuration COMPARE command allows the validation of information to
what exists in the non-volatile storage device without programming that
information. The COMPARE command is used in a configuration file, and placed
on the same line after the FRU name to be compared.
The compare functionality does a byte-by-byte comparison of the non-volatile
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.
Loads Specified SDR File
The normal method of loading an SDR file is through the use of a configuration
file. Typically all possible Sensor Data Records exist in one master SDR file.
Each SDR file name is specified after the SDRNAME configuration command.
Through the configuration file, tags may be use to selectively chose which records
are to be programmed using tags. The maximum allowable length of any Sensor
Data Record is 64 bytes. Any larger records will be flagged as an error.
Example:
Writing SDR Record #36
Reading SDR Repository
SDR file was successfully written!
Programming complete, reboot server for normal
operation
Comparing the SDR File
The configuration COMPARE command was added to allow the comparing of
SDR information to what is in the SDR Repository without programming that
information. The COMPARE command is used in a configuration file and placed
on the same line after the SDR name to be compared. The compare functionality
does a byte by byte comparison of the non-volatile 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.
