重启MC控制器

如果能够登录操作系统,可以在操作系统执行命令

modprobe ipmi-devintf
modprobe ipmi-si
ipmitool mc reset cold

在系统级别变更后重启操作系统前,一定要确保带外能够正确访问终端,所以建议在操作系统中执行一次mc reset cold

注意,一定要加载impi模块,否则会提示无法找到设备

也可以远程访问

ipmitool -I lanplus -H IP -U username -P password mc reset cold

Ubuntu的ipmi

apt install ipmitool

远程访问终端

ipmitool -I lanplus -H IP  -U username -P password -E sol activate

重启服务器

ipmitool -I lanplus -H IP -U username -P password power reset

检查服务器sol日志(故障原因)

ipmitool sel list
