/**
 * Create storage level masking components to support the requested

 * account initiators that are in some already existent in some
 * StorageGroup. In such a case, the underlying masking component will be
 * "adopted" by the ExportGroup. Further operations against the "adopted"
 * mask will only allow for addition and removal of those initiators/volumes
 * that were added by a Bourne request. Existing initiators/volumes will be
 * maintained.
