The command 'luxadm probe' will show the virtual paths. If you do a
'luxadm display {pathname}' it will show the underlying physical paths.

The performance is often measured on the disk array of fibre channel switches.
In solaris 'iostat -tcx 5' is a nice tool, however I don't think it will show
traffic on the physical paths.

You could always dispable one path and ee if that impacts your application
performance.
