Example 1 with RPCGExportCompleter

use of com.emc.storageos.volumecontroller.impl.block.taskcompleter.RPCGExportCompleter in project coprhd-controller by CoprHD.

the class RPDeviceController method exportGroupCreate.

/*
     * RPDeviceController.exportGroupCreate()
     * 
     * This method is a mini-orchestration of all of the steps necessary to create an export based on
     * a Bourne Snapshot object associated with a RecoverPoint bookmark.
     * 
     * This controller does not service block devices for export, only RP bookmark snapshots.
     * 
     * The method is responsible for performing the following steps:
     * - Enable the volumes to a specific bookmark.
     * - Call the block controller to export the target volume
     * 
     * @param protectionDevice The RP System used to manage the protection
     * 
     * @param exportgroupID The export group
