适用场景

  • ONTAP
  • FlexArray
  • E系列

问题描述

  • storage disk show 命令引发错误、指出-  "This array LUN is only available on one path. Proper configuration requires two paths
  • FC启动程序端口直接连接到E系列存储。
  • 对于使用E系列存储直接连接的FlexArray存储、阵列LUN仅显示在三个路径上、而不是显示在四个路径上。

  • 尽管指向另一个FlexArry节点(即节点:1)的路径存在冗余路径、但仍反映了上述错误。
  • FlexArray存储上的所有启动程序端口均已启动并联机。
  • ucadmin show 输出显示了在NetApp端已正确配置为启动程序端口的端口。

  • 在直接连接到FlexArray存储的E系列控制器上观察到琥珀色LED。

  • 已执行FC启动程序端口的换用、但问题描述仍存在。

注意: 命令— node run -node <node-name> storage disable adapter <adapter> 可运行以禁用FC启动程序端口、也  node run -node <node-name> storage enable adapter <adapter> 可运行以启用FC启动程序端口。
