Driver installation (optional, VTL only)
If you intend to create Virtual Tape Devices on the HP StoreOnce Backup system, two drivers are
required; an HP LTO Tape driver and a medium changer driver.
NOTE:
Certain backup applications require you to use their own drivers for both the tape device
and medium changer. For many applications these will be installed automatically during the
software installation process. If the backup software is already installed, you may need to manually
update the drivers after installing the HP StoreOnce Backup system.
HP LTO Tape driver
The HP LTO Tape driver must be installed to allow your system to recognize the Ultrium tape devices
created by the HP StoreOnce Backup system.
Tape drivers can be installed from the
drivers
directory on the HP StoreOnce Backup system
CD-ROM, where they are supplied as an installer application and as driver files for manual
installation. Also check the HP website for driver updates at
The tape drive is configurable as an LTO-2, LTO-3, LTO-4 or LTO-5 device. This is the default
behavior of the tape drive and there is no need and no way to change it on the HP StoreOnce
Backup system. It is important not to confuse emulation type with cartridge size. Emulation type is
totally independent from cartridge size. The HP StoreOnce Backup system allows you to pick
whatever cartridge size you like (up to 3.2 TB).
Medium changer driver
No additional medium changer driver is required because Microsoft Windows provides a suitable
generic driver and all backup applications provide their own changer drivers.
Device Manager
After installation, the HP StoreOnce Backup system does not appear as a device under
My Computer
and it is not mapped to a drive letter. You must always use a backup application on the host
machine to back up and restore data. However, if you have installed drivers, it can be seen as a
tape drive (

) from Device Manager.
