question: private void validateMaskAndPlaceVolumes ( StorageSystem array , URI varrayURI , Map < URI , ExportMask > maskSet , Set < URI > invalidMasks , ExportMask mask , ExportMaskPlacementDescriptor placementDescriptor , Map < URI , Volume > volumeMap , String logMsg ) { if ( ! isOpenStack ( array ) ) { _log . info ( logMsg ) ; if ( VPlexBackEndOrchestratorUtil . validateExportMask ( varrayURI , _initiatorPortMap , mask , invalidMasks , _directorToInitiatorIds , _idToInitiatorMap , _dbClient , _coordinator , _portWwnToClusterMap ) ) { maskSet . put ( mask . getId ( ) , mask ) ; placementDescriptor . placeVolumes ( mask . getId ( ) , volumeMap ) ; } for ( URI invalidMask : invalidMasks ) { placementDescriptor . invalidateExportMask ( invalidMask ) ; } } else { maskSet . put ( mask . getId ( ) , mask ) ; placementDescriptor . placeVolumes ( mask . getId ( ) , volumeMap ) ; } }
target:  Validate the mask for only non OpenStack storage systems now. For OpenStack, Export Mask will get validated later before the zoning step
