Steps
1. If you are connected to a Data Collector, select a Storage Center from the drop-down list in the left navigation pane of
Unisphere Central.

Create a Local Recovery Volume (View Volume) from a Snapshot
Create a recovery volume (view volume) from a snapshot to access data that is contained in the snapshot. A volume created
from a snapshot accesses the same data and consumes the same amount of space as the original volume. It will consume more
space when new data is written to the new volume.
Prerequisites
QoS Profile options are shown only if Allow QoS Profile Selection has been enabled on the Storage Center Preferences
dialog box.
