- Purchase a Virtual Tape Library Unlimited Drive Option for each library that exceeds the one drive limit.
- Disable the drives on the virtual tape library that exceed the one drive limit that is included with Backup Exec.



A Virtual Tape Library Unlimited Drive Option is required per attached library


To avoid seeing this message again, you can purchase a Virtual Tape Library Unlimited Drive Option for unlimited drive support in a virtual tape library. Or, you can purchase additional single Library Expansion Option licenses for each additional drive in the virtual tape library.
