Re: [Freeipmi-users] freeipmi command equivalent to ipmitool fru read/write <fru id> <file>

[CARANNANTE, MARTINE]

Hi
The reason to have these functions (read/write fru) is to be able to backup and 
restore FRU after having changed a board.
The contents of FRU are manufacturer specific but not the commands. These 
commands are IPMI standard.

In ipmitool, these functions are implemented in lib/ipmi_fru.c . 
(read_fru_area() and write_fru_data()).

In freeipmi, there is a beginning of implementation in 
./libfreeipmi/cmds/ipmi-fru-inventory-device-cmds.c

Inform me of your decision.
Thanks
Best regards
Martine

Subject: Re: [Freeipmi-users] freeipmi command equivalent to ipmitool fru 
read/write <fru id> <file>

At present there is no equivalent to "fru read" and "fru write".  My 
understanding is that this is to read/write fru binary files from/to a board.  
Since this is manufacturer specific, there's never been a request for it in 
FreeIPMI.

Is there a particular reason for this need?
