Provisioning from storage volumes

Provision from Storage Volumes wizard allows you to provision a virtual volume directly from a storage volume or preserve data on an existing storage volume that you want to expose to hosts. The wizard simplifies the provisioning process by automatically claiming storage (if not already claimed) and creating all of the underlying storage objects (extents and devices), and then creating a local or distributed virtual volume that is the total capacity of the selected storage volume. When provisioning from storage volumes, you can create only one virtual volume at a time. Each virtual volume that you create maps to a storage volume on the array. You can provision from storage volumes using integrated or non-integrated storage arrays. Provisioning Overview provides more information about integrated and non-integrated storage.

Creating a new virtual volume is as simple as selecting or creating a consistency group for the volume, selecting mirroring options (optional), and then selecting an available storage volume from an array on the cluster on which you want to create the virtual volume. You do not need to claim the storage volume before you begin to provision, and you can select claimed or unclaimed storage volumes from the selected array.

The Provision from Storage Volumes wizard consists of the following steps:

1. Select an existing consistency group for the volume or create a consistency group.
2. Select  mirroring options (optional) and synchronization options (if applicable) and provide a name for the virtual volume.
3. Select a storage volume to use to create the virtual volume.
4. Expose the virtual volume to hosts by selecting a storage view (optional).
5. Review your selections, and submit the provisioning request.
6. View the results of the operation.
