适用场景

  • AFF型号
  • FAS型号

问题解答

1.系统必须处于加载程序提示符处。  按照 如何访问加载程序提示符解决指南

  • 在AFF A400、FAS9300或FAS4700系统中、加载程序是从启动设备加载的。 
    • 按照" 更换启动介质 文档"中的步骤3 (或与使用问题描述的平台等效的文档)、使用外部USB启动设备访问加载程序并检查是否报告启动设备。

2.显示本地设备:

  • 对于大多数系统- LOADER-A> show devices -a
  • 如果该格式产生错误、请输入不带-a参数的 - LOADER-A> show devices

3.输出内容如下所示:
