我手里有一台旧服务器，正在尝试让 IPMI 正常工作。
服务器主板是SE7520JR2（SE7520JR22S, SE7520JR22.86B.P.08.10.0081.051820051126）
$ dmidecode -t 38
# dmidecode 2.11
SMBIOS 2.3 present.
Handle 0x0038, DMI type 38, 18 bytes
IPMI Device Information
Interface Type: SSIF (SMBus System Interface)
Specification Version: 1.5
I2C Slave Address: 0x10
NV Storage Device: Not Present
Base Address: 0x42 (SMBus)
我有 I2C 端口通过
$ modprobe i2c-i801
$ modprobe i2c-dev
$ ls -lsa /dev/i2c-0
0 crw-rw---T 1 root i2c 89, 0 Apr 18 01:55 /dev/i2c-0
我还获得了 BMC 信息
$ bmc-info -D ssif --disable-auto-probe --driver-address=0x42 --driver-device=/dev/i2c-0
Device ID : 32
Device Revision : 1
Device SDRs : supported
Firmware Revision : 2.40
Device Available : yes (normal operation)
IPMI Version : 1.5
Sensor Device : supported
SDR Repository Device : supported
SEL Device : supported
FRU Inventory Device : supported
IPMB Event Receiver : supported
IPMB Event Generator : unsupported
Bridge : unsupported
Chassis Device : supported
Manufacturer ID : Intel Corporation (343)
Product ID : 17169
输出似乎ipmi-chassis-config也不完整
$ ipmi-chassis-config -D ssif --disable-auto-probe --driver-address=0x42 --driver-device=/dev/i2c-0 --checkout

问题是ipmi_smb内核驱动程序自内核版本 2.6.35/36 以来就不存在了，并且ipmi_si不适用于钢坯/I2C配置（据我所知 modinfo）。
因此任何类似的工具ipmitool都会失败（Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory）
后续内核是否支持 SSIF IPMI 设备，或者能否以某种方式添加？
我正在运行 Debian 7.4（3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux）。
答案1
我不这么认为。我这里有同样的旧硬件，而且我也停留在内核 2.6.35。看来补丁没有移植到较新的内核版本 :/
