由于在E系列框上映射问题描述、FlexArray上出现"此阵列LUN仅在一个路径上可用"错误
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。
