Guide
For the steps to begin provisioning storage, see Guide. In the Guide, each step is a link that opens the UI screen that is required
to perform the step. To view the Guide, click Provision Storage, and then expand the GUIDE at the upper-right corner of the
screen. For more information about a step, click MORE for that step to open the associated help topic.
Distributed storage
Distributed storage sees storage objects that are created by using storage from both clusters. To view distributed storage, click
Provision storage, and then select Distributed Storage from the Provision on drop-down, and then select a required view
from the View By drop-down.
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.
