Ciao Gianni
I think you have a direct attaced storage array ? FC zoning on UCS is strictly controlled by UCS Manager, e.g. you define your initiators pwwn within your service profile, same for FC target pwwn.
I assume, you would like to attach a non-UCS server with hba to the fabric interconnect, and then use the above zoning.
In addition to FC you would also need a Ethernet / IP connectivity ? this will not work either; remember, FI is not a N5k.
Summary
Unfortunately, non-UCS server integration in UCS is not supported !
