question: public Map < URI , List < URI > > assignStoragePorts ( StorageSystem storage , ExportGroup exportGroup , List < Initiator > initiators , StringSetMap existingZoningMap , ExportPathParams pathParams , Collection < URI > volumeURIs , NetworkDeviceController networkDeviceController , URI virtualArrayUri , String token ) { StringSetMap preZonedZoningMap = assignPrezonedStoragePorts ( storage , exportGroup , initiators , existingZoningMap , pathParams , volumeURIs , networkDeviceController , virtualArrayUri , token ) ; Map < URI , List < URI > > assignments = assignStoragePorts ( storage , virtualArrayUri , initiators , pathParams , preZonedZoningMap , volumeURIs ) ; ExportUtils . addPrezonedAssignments ( existingZoningMap , assignments , preZonedZoningMap ) ; return assignments ; }
target:  This function wraps the two calls necessary to get port assignments, the first one is getting pre-zoned ports assigned followed by the call to add any additional ports.
