How do I access the WWNs via the transport field in a Fibre Channel path?

[ericwest-boston]

for _, lun := range hss.StorageDeviceInfo.MultipathInfo.Lun { for _, path := range lun.Path { fmt.Printf("FC Lun path xport: %v\n", path.Transport) }

Will print out:
FC Lun path xport: &{{{}} 2769714599750104683 2341872635149907563}

However, having tried more than a few approaches, I am unable to access the two WWN values

Interesting if using the VS Code debugger, in the debug window:
path.Transport github.com/vmware/govmomi/vim25/types.BaseHostTargetTransport(*github.com/vmware/govmomi/vim25/types.HostFibreChannelTargetTransport) *{HostTargetTransport: github.com/vmware/govmomi/vim25/types.HostTargetTransport {DynamicData: github.com/vmware/govmomi/v... data: *github.com/vmware/govmomi/vim25/types.HostFibreChannelTargetTransport {HostTargetTransport: github.com/vmware/govmomi/vim25/types.HostTargetTransport {DynamicData: github.com/vmware/govmomi/vim25/types.DynamicData {}}, PortWorldWideName: 27697145997501046... github.com/vmware/govmomi/vim25/types.HostFibreChannelTargetTransport {HostTargetTransport: github.com/vmware/govmomi/vim25/types.HostTargetTransport {DynamicData: github.com/vmware/govmomi/vim25/types.DynamicData {}}, PortWorldWideName: 276971459975010468... HostTargetTransport: github.com/vmware/govmomi/vim25/types.HostTargetTransport {DynamicData:github.com/vmware/govmomi/vim25/types.DynamicData {}} PortWorldWideName: 2769714599750104683 NodeWorldWideName: 2341872635149907563

...and I can access the WWNs directly in that console
path.Transport.NodeWorldWideName 2341872635149907563

So how do I do this programmatically? ex fmt.Println(path.Transport.NodeWorldWideName)
Note too: VS Code claims NodeWorldWideName is not a field for Transport

Thanks!

path.Transport here is base type HostTargetTransport, which has 8 subtypes. You can use Go's type assertions to access specific fields:

		for _, path := range lun.Path {
			switch xport := path.Transport.(type) {
			case *types.HostFibreChannelTargetTransport:
				fmt.Printf("wwn=%d\n", xport.PortWorldWideName)
			default:
				fmt.Printf("type=%T\n", xport)
			}
		}

Doh! of course.

Intuitively obvious :)

Thanks! -- I might still have some hair left :p
