Example 1 with RPCGExportDeleteCompleter

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

the class RPDeviceController method exportGroupDelete.

/*
     * RPDeviceController.exportGroupDelete()

     * This method is a mini-orchestration of all of the steps necessary to delete an export group.

     * This controller does not service block devices for export, only RP bookmark snapshots.
     * 
     * The method is responsible for performing the following steps:
     * - Call the block controller to delete the export of the target volumes
     * - Disable the bookmarks associated with the snapshots.
