ipmb init失败问题分析
更新时间： 2026/05/28
在Gitcode上查看源码

问题背景 ​

  • 单板类型：NA；
  • 软件版本：openUBMC 25.03；
  • 涉及功能：ipmb init；
  • 触发条件：1230版本配置固定的ipmb地址是在platform.sr下的，可以成功，现在2503版本因为要动态获取挪到了root.sr下面。
  • 业务表现：预期ipmb init成功；实际ipmb init失败，报了channel，instance is invalid错误。

问题复现步骤 ​

  1. 1230版本配置固定的ipmb地址是在platform.sr下的，可以成功，现在2503版本因为要动态获取挪到了root.sr下面。
  2. ipmb init失败，报了channel，instance is invalid错误

关键日志信息 ​

查看日志，确认报错如下：

    }

以上配置在1230版本上都是ok的： 但是在2503版本上提示ERROR：ipmb init failed, because channel , instance is invalid

问题原因 ​

新版本与旧版的配置上会有所差异。

解决方案 ​

修改新版上的配置：

  1. IPMB和IPMIChannel和ChannelID作为IPMB都要配成6

  2. ChanType为1

  3. IPMB的Instances属性要和IPMIChannel的Instance对应
