Example 1 with ResourceAndUUIDNameGenerator

use of com.emc.storageos.db.client.util.ResourceAndUUIDNameGenerator in project coprhd-controller by CoprHD.

the class UnManagedVolumeService method ingestExportedVolumes.

/**
 * Ingest Exported Volumes
 *
 * For each UnManaged Volume Find the list of masking views this volume
 * is exposed to.
 *
 * If only 1 masking view verify if all the initiators are available on
 * the existing MV. Verify the storage Ports are available in given
 * VArray Verify if this export mask is available already If not, then
 * create a new Export Mask with the storage Ports, initiators from
 * ViPr. Else, add volume to export mask.
 *
 * If more than 1 masking view verify if all the initiators are
 * available on all existing MVs. Verify the storage Ports within each
 * Masking view are available in given VArray. Verify if this export
 * mask is available already If not, then create a new Export Mask with
 * the storage Ports, initiators from ViPr. Else, add volume to export
 * mask.
