from storage volumes provides detailed information. To provision from storage volumes, select CREATE > Provision from
Storage Volumes from Provision Storage view.
● Create a virtual volume on top of a device (top-level) — Use this option if you did not create a virtual volume at the time
that you created the device. This option allows you to add a virtual volume later. The volume is given the device name,
followed by _vol. To create a virtual volume on top of a device, select MORE>Create Virtual Volumes from the Devices
view.
● Use the Create Virtual Volumes wizard — Automatically creates a virtual volume using claimed or unclaimed storage
volumes, depending on where you launch the wizard. Launching the wizard from the Storage Arrays view gives you the
option of using claimed or unclaimed storage from the selected storage array, eliminating the separate step required to
claim storage first. Launching from the Storage Volumes view uses claimed storage only. If the wizard fails to create
the virtual volume, you can roll back the sub-components (extents and devices) created during the operation, or leave the
sub-components and manually create the virtual volume on the device. To open the Create Virtual Volumes wizard, click
Create Virtual Volumes from the Storage Volumes view or the Storage Arrays view.
NOTE: To create thin volumes, the supporting arrays must belong to the same family of arrays and the storage volumes
must also be thin-capable.
About virtual volume expansion
See the following method of volume expansion:
● Storage volume expansion — Allows online, non-disruptive expansion of the virtual volume taking the full "current capacity"
of the storage volume and making that "configured capacity" of the virtual volume. Expanding a volume using storage
volumes provides more information.
NOTE: Volumes cannot be expanded during a rebuild.
Expanding a virtual volume using storage volumes
About this task
Storage volume expansion allows online, non-disruptive of the virtual volume, using the full current capacity of a storage volume
and making that the configured capacity of the virtual volume. About virtual volume expansion provides more information.

2. In the Virtual volumes list, select one or more volumes with the Expansion Method of storage-volume and a capacity
greater than 0.
3. Select MODIFY>Expand.

Enabling or disabling remote access for a volume
About this task
Remote access allows you to make a virtual volume on a device in one cluster visible in the other cluster. Once you make a
virtual volume remotely accessible, you can include the volume in storage views in either cluster. The virtual volume's Visibility
attribute is Global in the Virtual Volumes view of both clusters. Note that you cannot disable remote access on a virtual volume
that is currently exported. To disable remote access, you must first remove the virtual volume from the storage view.
