单个 FC-SAS 网桥丢失

可以测试单个 FC-SAS 网桥的故障，以确保没有单点故障。

此测试应该需要大约 15 分钟。

此过程具有以下预期结果：

  • 网桥关闭时应生成错误。

  • 不应发生故障转移或服务中断。

  • 从控制器模块到网桥后方的驱动器之间只有一条路径可用。

  1. 关闭网桥的电源模块。
  2. 确认网桥监控指示了错误：storage bridge show 

    cluster_A::> storage bridge show

                                                                Is        Monitor

  3. 确认通过单条路径即可访问网桥后方的驱动器：storage disk error show 

    cluster_A::> storage disk error show
