question: public static boolean isZoningRequired ( DbClient dbClient , URI varrayUri ) { if ( varrayUri != null ) { VirtualArray nh = dbClient . queryObject ( VirtualArray . class , varrayUri ) ; if ( nh != null ) { return isZoningRequired ( dbClient , nh ) ; } } return false ; }
target:  Looks at the varray to see if zoning is disabled, and looks to make sure that there is at least one active NetworkSystem registered.
