This may take a few minutes. Thanks for your patience.
Your file is ready
You can use the plug-in to create consistency group snapshots for resource groups. A consistency group is a container that can house multiple volumes so that you can manage them as one entity. A consistency group is simultaneous snapshots of multiple volumes, providing consistent copies of a group of volumes.
You can also specify the wait time for the storage controller to consistently group snapshots. The available wait time options are Urgent, Medium, and Relaxed. You can also enable or disable Write Anywhere File Layout (WAFL) sync during consistent group snapshot operation. WAFL sync improves the performance of a consistency group snapshot.
