使用 SUM 工具修改超微 BIOS 配置

WHY

厂里有一批 过保 的 Supermicro 3U8 机器 CPU 没有启用 超线程

虽然超微 3U8 机型 X9SRD-F 主板使用的也是 AMI BIOS

BIOS Type: 32Mb SPI Flash EEPROM with AMI BIOS

但之前针对 H3C 机型修改 BIOS 的 SCELNX 工具不能用:

# SCELNX_64 /o /lang /s BIOS-with-map-string.cfg /hb
Platform identification failed.

AMI 官网也没找到适配该主板的工具下载,只得用超微自己的 SUM 工具来修改

WHAT

Supermicro Update Manager (SUM)

BIOS Management

  • Update BIOS Firmware

HOW

当前 CPU 没启用超线程,只有 4 个核:

# dmidecode -t processor | grep -E '(Core Count|Thread Count)'
        Core Count: 4
        Thread Count: 8

License Key

使用 sum 工具修改 BIOS 需要 License Key 厂里的机器也都没有 –.

好在超微 旧机型 (2012-2018) 的 License 算法已经被 逆向 出来了:

Reverse Engineering Supermicro IPMI 2018-05-27

根据 OOB Mac 地址计算 License Key :

oob_mac_str=$(ipmitool lan print|awk '/^MAC Add/{print $4}')
oob_hex_key=8544E3B47ECA58F9583043F8

echo "$oob_mac_str"|xxd -r -p|openssl dgst -sha1 -mac HMAC -macopt "hexkey:${oob_hex_key}"|awk '{print $2}'|awk -v FIELDWIDTHS='4 4 4 4 4 4' -v OFS='-' '{$1=$1;print }'
a2a5-e0de-ebbe-0862-53e2-5e16

导入 License Key :

# ./sum -c  ActivateProductKey --key a2a5-e0de-ebbe-0862-53e2-5e16
Supermicro Update Manager (for UEFI BIOS) 2.2.0 (2019/02/20) (x86_64)

Node product key (OOB) is activated for localhost.

# ./sum -c QueryProductKey

[0] OOB
Number of product keys: 1

然后就可以使用 sum 工具配置 BIOS 了,先查看当前 BIOS 里的 超线程 HT 配置项:

# ./sum -c GetCurrentBiosCfg |grep -C3 -i thread
[Advanced|CPU Configuration]
Clock Spread Spectrum=00                // *00 (Disabled), 01 (Enabled)
RTID=00                                 // *00 (Optimal), 01 (Alternate)
Hyper-threading=00                      // 00 (Disabled), *01 (Enabled)
Limit CPUID Maximum=00                  // *00 (Disabled), 01 (Enabled)
Execute Disable Bit=01                  // 00 (Disabled), *01 (Enabled)
Intel(R) AES-NI=01                      // 00 (Disabled), *01 (Enabled)

当前没有启用,生成启用 HT 的 BIOS 配置文件:

# echo '[Advanced|CPU Configuration]
Hyper-threading=01                      // 00 (Disabled), *01 (Enabled)' > ht.cfg

# cat ht.cfg
[Advanced|CPU Configuration]
Hyper-threading=01                      // 00 (Disabled), *01 (Enabled)

最后 sum 通过生成的 启用 HT 配置文件 修改 BIOS :

# ./sum -c ChangeBiosCfg --file ht.cfg
Supermicro Update Manager (for UEFI BIOS) 2.2.0 (2019/02/20) (x86_64)

Status: Start updating the BIOS configuration for the managed system

************************************WARNING*************************************
    Do not remove AC power from the server.
********************************************************************************

Status: The BIOS configuration is updated for the managed system

Note: You have to reboot or power up the system for the changes to take effect

修改成功后,还需 重启 服务器才能生效。重启之后,确认 HT 是否生效:
