Issue
storage disk showcommand throws error stating- "This array LUN is only available on one path. Proper configuration requires two paths"- The FC Initiator ports are directly connected to the E-Series Storage.
- Array luns were visible only on three paths instead of four paths for directly connected FlexArray Storage with E-Series Storage.

NET-1.35 (6d039ea00003564e000001385xxxxxxx): This array LUN is only available on one path. Proper configuration requires two paths.
- Although redundant paths were there to the other FlexArry Node i.e Node:1, still this above error is reflecting.
- All the Initiator ports are up and online on FlexArray storage.
ucadmin showoutput shows the port configured correctly on NetApp end as initiator ports.

- Amber LED observed on E-Series controller connected directly to the FlexArray Storage.
- Toggling of FC initiator port was performed, but the issue still persists.
Note: Command - node run -node <node-name> storage disable adapter <adapter> can be run to disable the FC Initiator port and node run -node <node-name> storage enable adapter <adapter> can be run to enable the FC Initiator port.
