使用 SCELNX 修改浪潮 BIOS
分类：Server 标签：Bios
WHAT
厂里一批浪潮 Inspur SA5212M4 型号机器在 CentOS 8 下无法使用 isrest 工具修改 BIOS：
# cat /etc/redhat-release
CentOS Linux release 8.2.2004 (Core)
# ipmitool bmc info|grep ^Firmware
Firmware Revision : 4.08
# /opt/ISREST-Linux-V6.0.0/bin/isrest setBios -A Numa -V Enable
Failure: Error in opening command.
测试了一番发现 BMC 固件版本 低于 4.08 以下 是失败的 4.09 和 4.11 版本的 BMC 固件正常：
# ipmitool bmc info|grep ^Firmware
Firmware Revision : 4.09
# cat /etc/redhat-release
CentOS Linux release 8.2.2004 (Core)
# /opt/ISREST-Linux-V6.0.0/bin/isrest setBios -A Numa -V Enable
--------------------------------------------------
Success: Set bios success.
--------------------------------------------------
# cat /etc/redhat-release
CentOS Linux release 8.2.2004 (Core)
# ipmitool bmc info|grep ^Firmware
Firmware Revision : 4.11
# /opt/ISREST-Linux-V6.0.0/bin/isrest setBios -A Numa -V Enable
--------------------------------------------------
Success: Set bios success.
--------------------------------------------------
WHY
BMC 4.08 版本的固件修改 BIOS 时调用的 IPMI raw 指令异常报错：
# strace -f -e trace=write -o /tmp/strace-bios.log -s 1024 /opt/ISREST-Linux-V6.0.0/bin/isrest setBios -A Numa -V Enable
# tail -20 /tmp/strace-bios.log

HOW
对于 BMC 固件版本低于 4.08 的机器使用 SCELNX_64 修改 BIOS ：
#!/bin/bash
if ! dmidecode -t 1 | grep -iq inspur
then
echo "__ERROR: ONLY for INSPUR server"
exit 2
fi
bmc_ver=$(ipmitool mc info|awk '/^Firmware/{print $NF}')
if awk 'BEGIN {exit !('$bmc_ver' <= '4.08')}'
then
chmod u+x /root/SCELNX_64
/root/SCELNX_64 /o /lang /s /root/bios.cfg
grep -A7 -i numa /root/bios.cfg
numa_map_string=$(grep -A7 -i numa /root/bios.cfg|awk '/Map String/{print $NF}')
if [ -n "$numa_map_string" ]
then
/root/SCELNX_64 /i /ms $numa_map_string /qv 0x01
/root/SCELNX_64 /o /ms $numa_map_string
fi
fi
脚本执行过程：
+ dmidecode -t 1
+ grep -iq inspur
++ ipmitool mc info
++ awk '/^Firmware/{print $NF}'
+ bmc_ver=4.07
+ awk 'BEGIN {exit !(4.07 <= 4.08)}'
+ /root/SCELNX_64 /o /lang /s /root/bios.cfg
