FRU & SDR Load Utility Functional Operation
Using the information in the configuration file, the utility can probe the product
configuration. The following sections describe the operation of the FRU and SDR
Load Utility. For the latest information regarding the utility, please visit the HP

Configuration File
A CFG file may be used by the utility. The configuration file is ASCII text and
editable. The file is parsed, and then 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 the user to override values contained in an
associated FRU file; it does not allow you to add areas to a FRU file. One should
think of the FRU in the non-volatile storage device as containing the default
values. If you decide to 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 non-volatile storage of the
BMC and possibly generic FRU devices. Some of the commands are user
interactive and require a choice to be made by the user.
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
also 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 never been
initialized.
If the Internal Use Area of the BMC is loaded from the FRU file, then the BMC
will be cold reset. This is so the BMC 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 will be lost and the SDR's must be reprogrammed.
Updating the SDR Non-Volatile 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 SDR file is loaded via the configuration file. After the file is loaded,
the utility filters all tagged SDRs depending on the product configuration set in
