Driver mpt2sas0 spam dmesg - mpt2sas0: log_info(0x30030110): originator(IOP), code(0x03), sub_code(0x0110) 提供了排查思路：

  • 在运行 sas2ircu-status 时会出现上述消息
  • Dell提供了一个内建的检测工具可以检查SAS相关故障码
  • Russell McOrmond (russell-flora) wrote on 2012-07-11: 更新存储卡的firmware可以修复这个问题

排查案例：

检查硬件

这里111000似乎是一个异常的信息，服务器显示负载极高，磁盘iowait达到40+，检查磁盘sdg故障导致util达到100，采用mpt2sas下线故障磁盘方法处理后，这个0x31111000不再出现。
