Trunk Info -
If the configuration of the switch port is configured as auto, and the point-to-point link still comes up as
an FL port, verify that the HBA is configured as an NL port also.
Some HBAs support only NL mode. Verify the HBA capabilities with the vendor.

Interface UP and Connectivity Problems - Troubleshooting VSANs and Zones

If a server is not able to see a storage device, it may be because of a VSAN or zone misconfiguration.
Zone problems are more likely to happen than VSAN issues. This is because zone configuration and the
overall zone protocols are more complex than VSAN configuration, and the VSAN membership can be
verified using the CLI or the GUI. Therefore, checking the zone configuration is the first step to take
when the host is not able to access the storage, and the port are all up along the path between the server
HBA and the storage subsystem interface.
