Driver Installation (Optional, Vtl Only) - HP StoreOnce 4900 Backup Installation And Configuration Manual

Driver installation (optional, VTL only)

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 their own drivers for both the tape device and medium
changer. For many applications these are installed automatically during the software installation
process. If the backup software is already installed, you may need to update manually 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 link 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 http://www.hp.com/support.
The tape drive is configurable as an LTO-2, LTO-3, LTO-4, LTO-5 or LTO-6 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
independent from cartridge size. The HP StoreOnce Backup system allows you to pick a cartridge
size 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. The host machine requires a backup application to back up
and restore data. However, if drivers are installed, the backup system can be viewed as a tape
drive (1) and medium changer (2) from the Device Manager.
