I do want to know the zoning best practices for VMAX, like is it minimum  2 FAs should be contained in a zone or even 1FA with 1 initiator is also okay ?

like imagine like i have fabA and fabB with hbaA ,FA1, FA2 connected to FabA and hbaB ,FA3, FA4 connected to FabB. here have to create zoneA and ZoneB like here the basic zoning would be a zoneA with hbaA and FA1 and zoneB with hbaB and FA3 as its members, what is the best practice do we need to have like 2 FAs atleast for VMAX to brocade or any switch zoning?
