Example 1 with ZoneInfoMap

use of com.emc.storageos.db.client.model.ZoneInfoMap in project coprhd-controller by CoprHD.

the class NetworkDeviceController method refreshZoningMap.

/**
 * Update the zoning map for as export mask previously "accepted". This applies to
 * brown field scenarios where a export mask was found on the storage array. For
 * those export masks, changes outside of the application are expected and the
 * application should get the latest state before making any changes. This
 * function is called from ExportMaskOperations#refreshZoneMap after all
 * updates to the initiators, ports and volumes were made into the export mask and
 * the export group. The update steps are as follow:
 * <ol>
 * <li>Get the current zones for those initiators that were not added by ViPR and the storage ports that exist in the mask.</li>
 * <li>Diff the current zones with those in the export mask and update the zoning map</li>
 * <li>Update the FCZoneReferences to match the zone updates</li>
 * </ol>
 * Note that ViPR does not keep FCZoneReferences only for volumes created by ViPR. As those
 * volumes are not updated by ExportMaskOperations#refreshZoneMap, no additional code
 * is needed to remove FCZoneReferences for removed volumes.
 *
 * @param exportMask the export mask being updated.
 * @param removedInitiators the list of initiators that were removed. This is needed because
 *            these were removed from the zoingMap by {@link ExportMask#removeInitiators(Collection)}
 * @param removedPorts the set of storage ports that were removed
 * @param maskUpdated a flag that indicates if an update was made to the mask that requires
 *            a zoning refresh
 * @param persist a boolean that indicates if the changes should be persisted in the db
