Examples with ApplicationTaskCompleter com.emc.storageos.volumecontroller.impl.block.taskcompleter.ApplicationTaskCompleter used on opensource projects

Example 1 with ApplicationTaskCompleter

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

the class BlockDeviceController method updateApplication.

/**
 * Adding/removing volumes to/from an application is ViPR DB only operation (no controller side involved),
 * except for adding VNX volumes to an application, if the VNX volumes are in a real replication group.
 *
 * 1. remove volumes from replication group, keep volume's replicationGroupInstance unchanged
 * 2. delete the replication group from array, keep CG's systemConsistencyGroup unchanged
 * 3. change CG's arrayConsistency to false, update volume's volumeGroupIds, update clone's fullCopySetName
 * (performed in the completer class)
