Backup Exec periodically searches for new storage arrays or new physical disks. If Backup Exec does not find a new storage array or physical disk that you added, then you should run a refresh operation. If a refresh operation does not discover the new devices, then restart the Backup Exec services.
After you restart the services, the new storage array appears in the Devices view.
You must install the Storage Provisioning Option before Backup Exec can detect a new storage array.
