我想用来ipmitool获取主板序列号，目前我可以用来$ sudo ipmitool fru查询以下信息：
$ sudo ipmitool fru
FRU Device Description : Builtin FRU Device (ID 0)
Chassis Type : Main Server Chassis
Chassis Part Number : 01234567

Board Mfg Date : Wed Jan 7 13:07:00 2015
Board Mfg : GIGABYTE

因为在我的项目中，我需要在 C 代码中使用 OpenIPMI API 来获取 Board Serial，所以我认为这应该是唯一的。因此，我使用 raw 命令：
$ 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)
然后，尝试发出以下命令来了解有关原始命令格式的更多信息
$ 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
我已经在Google上搜索了好几天，但找不到任何信息，并且我已经下载了ipmitool的源代码，也许我会尝试更清楚地阅读源代码。
顺便说一句，我已经从 SuperMicro 下载了 IPMI 实用程序“IPMICFG”，并按照指南Supermicro IPMI 设备配置使用 IPMICFG，并读取OpenIPMI 简介。
我的问题是，我应该使用什么netfn代码，获取 Board Serial 的命令是什么，在这种情况下，值应该是GG3P8800012。
有什么建议吗？
提前致谢。
谢谢@Lenniey
以下是输出sudo ipmitool fru -vvv：

这里又引出另一个问题：如何从输出中获取原始命令线索sudo ipmitool fru -vvv？
答案1
要读取 FRU，您需要使用以下命令：
ipmitool raw 0xa 0x11 <offset lsb> <offset msb> <count>
您将需要计算电路板串行的偏移量，但您可以通过反复试验（或实际进行计算）来完成。
响应将是
- 第一个字节：读取的字节数。
- 第二个字节及以后：读取的原始数据。
