适用场景

  • AF-A800、AF-C800、ASA-A800、ASA-C800
  • AF-A250、AF-C250、ASA-A250、ASA-C250、FAS500f
  • 仅限内部使用的NVMe存储驱动器

问题解答

  • 如果AFF或ASA存储系统安装了仅限内部使用的NVMe固态驱动器(SSD)、则此 系统的系统存储配置将显示在Sysconfig nochell命令行界面输出中的单路径HA:

  • 单路径HA为预期值且正常
    • 机箱中的每个控制器都与 系统内部磁盘架中安装的每个NVMe SSD有一个基于PCIe的直接连接。 
    • 这些内部连接的主机总线适配器(Host Bus Adapter、HBA)端口为虚拟端口、即
      Virtual NVMe Host Adapter 0n
  • 如果 已将外部存储架添加到系统中、则如果外部存储架布线正确、则系统存储配置应显示为Multi-Path HA。
