When I create a volume with the GUI, I have to choose NAS or SAN.
But after creating it I can't see anyware if the volume is SAN or NAS created.
How can I see how the volume was creates ?

You can't. This is question about intended usage. Wizard will set some options differently, depending on it; each of these options can be changed independently at any time also after initial volume creation.
This question is there to set some recommended defaults, nothing more.
