After you install the Storage Provisioning Option, Backup Exec adds the All Virtual Disks device pool to the list of device pools. The All Virtual Disks device pool contains all virtual disks from all storage arrays on all computers in the Backup Exec environment.
Individual virtual disks do not appear in the All Devices <computer_name>device pool. However, you can select a specific virtual disk as a destination device for a job.
You cannot add nonvirtual disk devices to the All Virtual Disks device pool.
