About adding storage devices in a CAS environment

From the central administration server, you can run the Configure Storage Wizard to set up devices for the central administration server or for any of the managed Backup Exec servers. After managed Backup Exec servers are installed, they appear on the Storage tab of the central administration server. When you start the Configure Storage Wizard, you are prompted to select the server for which you want to configure storage. You can choose the central administration server or any managed Backup Exec server that runs the same version of Backup Exec as the central administration server.
