Do we have to enable NPV before turning on the ports on the switches for Blade Enclosures. Would it bring the fabric down if we did not enable the NPV and connected the blades to 9513's?

I mean if we connected an ISL link between the 9124 in the blade enclosure and a 9513 edge switch would the two VSAN's merge and take down the fabric if 9124 were to be a switch with lower WWN or with a higher domain ID?

What affect does the NPV being enable or disable mean to a 9124 which is a new switch and has no zoning database with just 1 VSAN 500 and no servers connected to it and 9513 is a production edge switch with 500 as the production VSAN.

I do understand that if NPV were not enable and blades servers were there then it would cause a problem for the servers to communicate.
