Install the Storage Provisioning Option on a local media server as a separate add-on component of Backup Exec.
You can install the Storage Provisioning Option when you upgrade from a previous version of Backup Exec. However, the default device pool from the previous version is kept. The All Virtual Disks device pool is not set as the default device pool.
