I would like to use ipmitool to get the Board Serial Number, currently I can use $ sudo ipmitool fru to query the information as below:

$ sudo ipmitool fru
FRU Device Description : Builtin FRU Device (ID 0)
 Chassis Type          : Main Server Chassis
 Chassis Part Number   : 01234567
 Chassis Serial        : 01234567890123456789AB
 Board Mfg Date        : Wed Jan  7 13:07:00 2015
 Board Mfg             : GIGABYTE
 Board Product         : MB10-DS4
 Board Serial          : GG3P8800012
 Board Part Number     : 01234567
 Product Manufacturer  : GIGABYTE
 Product Name          : MB10-DS4
 Product Part Number   : 000000000001
 Product Version       : 0100
 Product Serial        : 01234567890123456789AB
 Product Asset Tag     : 01234567890123456789AB

Because in my project, I need to use OpenIPMI API in C code to get the Board Serial, I think that should be unique. So, I use the raw command:

$ sudo ipmitool raw
Not enough parameters given.
RAW Commands:  raw <netfn> <cmd> [data]

Network Function Codes:

  VAL   HEX     STRING
==============================================
  0     0x00    Chassis
  2     0x02    Bridge
  4     0x04    SensorEvent
  6     0x06    Application
  8     0x08    Firmware
  10    0x0a    Storage
  12    0x0c    Transport

(can also use raw hex values)

Then, try to issue following command for to know more about the raw command format

$ sudo ipmitool raw 0 0
 01 20 20 20 20 20
$ sudo ipmitool raw 0 1
 21 00 00 70
$ sudo ipmitool raw 0 2
Unable to send RAW command (channel=0x0 netfn=0x0 lun=0x0 cmd=0x2 rsp=0xc7): 
Request data length invalid

I've googled for several days, but can not find any information, and I've downloaded the source code of ipmitool, maybe I'll try to read the source code more clearly.

BTW, I've downloaded the IPMI utility 'IPMICFG' from SuperMicro, and follow the guide Supermicro IPMI Device Configuration using IPMICFG, and read A Gentle Introduction with OpenIPMI.

My Question is, what is the netfn code should I use, and what is the command to get the Board Serial, is this case, the value should be GG3P8800012.

Any advice?

Thanks in advance.

Thanks @Lenniey

Follow the advice from @Lenniey, I issue following command:

Here raises another question: How to get raw command clues from the output of sudo ipmitool fru -vvv ?

  • I don't think you can use `raw` to extract this information. But anyway, could you edit the output of `sudo ipmitool fru -vvv`? Also: you can try your luck with this document: http://www.intel.com/content/www/us/en/servers/ipmi/ipmi-second-gen-interface-spec-v2-rev1-1.html – Lenniey Apr 27 '17 at 14:27
  • @Lenniey, thanks for your quick response, I've added the output of `ipmitool fru -vvv` in my question. – charles.cc.hsu Apr 28 '17 at 01:30
  • try `sudo ipmitool -v raw 0xa 0x11` or something like that. – Lenniey Apr 28 '17 at 06:49
  • @Lenniey, I've added the result to the end of the context, but I have another question: How to get the raw command clues from the output of `sudo ipmitool fru -vvv` ? and are you familiar with using OpenIPMI API in C code, I just want to set some unique number as the product serial number. Not really need the Board Serial field. It can be the Product Serial as well. – charles.cc.hsu Apr 28 '17 at 12:31
  • Sorry, I really don't know more but I think with some tinkering you might be able to get what you need – Lenniey May 05 '17 at 09:08
  • @Lenniey, it's OK. I installed the `ipmitool` from the source, modified the C code in the `lib` folder, added some func to get the information from the func call by `ipmitool sensor`, `ipmitool mc info` ,plus, I parsed the file `/proc/cpuinfo` to get the CPU model type. It's good enough for me to continue my project. Thanks, anyway. – charles.cc.hsu May 05 '17 at 12:10

    Woah, alright, sounds a bit extreme but whatever works :) You could add it as an answer, maybe. – Lenniey May 05 '17 at 13:13

To read the FRU you need to use the following command:

ipmitool raw 0xa 0x11 <offset lsb> <offset msb> <count>

You will need to calculate the offset of the board serial but that you can do with some trial and error (or actually do the math).

The response will be

  • First byte: number of bytes read.
  • Second byte onwards: the raw data that was read.
