Frusdr Load Utility - Dell 3250 Product Manual

FRUSDR Load Utility

The Field Replacement Unit (FRU) and Sensor Data Record (SDR) Load Utility
an Extensible Firmware Interface program that updates or modifies the server management
subsystem's product level FRU and SDR repository. This utility is used to program, compare, or
display FRU and/or SDR information. It must be run on an Intel Itanium 2 system executing
NSHELL under the EFI environment.
You should run the FRUSDR Load Utility each time you upgrade or replace the hardware in your
server; excluding add-in boards, hard drives, and RAM. The utility programs the sensors that the
server uses to monitor server management. Upon completing the programming of the FRU and/or
SDR areas, the server should be rebooted.
The normal method of loading one or more FRU files is through the use of a configuration file.
Each FRU file name is specified using the FRUNAME configuration command. The first time a
FRU file is programmed, all areas in the FRU file need to be written. This initialization should be
done in manufacturing. The FRUSDR utility does not support first time programming of FRU
areas.
Once the FRU file has been initially programmed, then you may use the FRUSDR utility to update
specific FRU areas and fields. You may not change the size of any FRU area from the size defined
in the original FRU Header. Through the use of a configuration file, each area of the FRU may
selectively be programmed. The FRU information written to the nonvolatile storage device is
verified after programming and an appropriate message is displayed. For more detailed information
on creating and using a configuration file see Configuration File.
Within the FRU file header is a pad byte that can be any one-byte value. This pad byte is used in
calculating the header checksum. If the header checksum is incorrect, then a message is displayed.
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 are flagged as an error.
Using the FRUSDR Load Utility, you can do the following:
•
Discover the product configuration based on instructions in a master configuration file.
•
Display the FRU information.
•
Update the nonvolatile storage device associated with the baseboard management controller
(BMC) that holds the SDR and FRU information.
•
Generically handle FRU devices that might not be associated with the BMC.
•
Supply command lines and interactive input through the standard input device.
•
View and direct results to the standard output device.
