In CDP 4.0 you might notice the Volume menu is not present by default on new installations. This menu can be activated by following the instructions listed below.
In the CDP server administration web page go to Configuration.
Then go to Product Features.
Then select any other option except the first one (Only Administrators Login to the CDP Server) to enable the 'Volumes' feature. Below is shown the "Use a custom configuration" option with the "Volumes" checkbox selected. Press the "Save" button. You do not have to select the 'Enable Hosting Control Panels' option to enable Volumes. You should only select that feature if you will use any of the Control Panels we support.
