User response

Moving the data from this volume to new volume will create a unique encryption key for the new volume and make the data more secure. Before moving the data, mark this volume READONLY to prevent Tivoli® Storage Manager from appending data to the volume. Then, use the MOVE DATA command to move the data from this volume to a new volume in your encryption storage pool.
