How do I connect the drive to my server?
For optimum performance the drive should be connected to a USB 2.0 port and it should be the only
device on the USB bus. Altho ugh the tape drive will function on USB 1.1, performance will be severely
degraded. See also “Verifying USB installation for o ptimum performance” on page 52. Appropriate
USB ca
For internal drives, the USB 2.0 connection may be via an internal port on the ser ver’s system board (as
in many newer ProLiants servers) or an external port on the server’s rear panel.

Mounting hardware
For many servers, no mounting tray or rails are required. Devices simply slide into the server’s chassis
and are fixed with screws. Other servers have built-in trays or rails.
Rail kits
h
ttp://www.hp.com/go/connect.
Some servers use non-standard m ounting rails and do not include spares. If this is the case with your
system, you will have to order these accessories from the server manufacturer before you can install the
tape drive.
for a number of industr y -standard servers may be available. For more details refer to:
Using the HP StorageWorks Tape CD-ROM
The HP StorageWorks Tape CD-ROM is a central source of information about your tape d rive with utilities

Install drivers
Installing on Windows
Two drivers are required in order to use HP StorageW orks DAT USB tape drives.
• hpdat: This i
available on the HP StorageWorks CD-ROM or on the HP Support web site.
• hp_usbstor: This is a USB Storage device used by hpdat and it replaces the Microsoft usbstor
driver for HP USB tape drives. The HP StorageWorks USB DAT drives will work with the Microsoft
usbstor driver, however, HP strongly recommends the use of the hp_usbstor driver as it offers
improved functionality.

s the tape driver that works with all HP DAT products. It is regularly updated and is
ains a driver install package for the following Microsoft Windows operating systems:
rver 2000, Windows Server 2003 and Windows XP. If you prefer to use Windows Device
Updates to the drivers may be provided from time to time on the HP support web site
(h
ttp://www.hp.com/support). We recommend that these are installed after using the installer on the
CD-ROM.
Recommended install process, before connecting the tape drive
1. Insert the StorageWorks CD
2. Select the install drivers link.
3. Run the automated installer and follow the process to load the two drivers onto the system.
4. Once you have installed the tape drive and rebooted, as described in this guide, the tape drive will
be detected automatically and the correct driver will be used.
Alternative install process, after connecting the tape drive

power on the server and tape drive.
Either:
Follow the on-screen instructions to search for the required drivers on the CD-ROM.
Or:
1. Cancel the wizard and insert the HP StorageWorks CD-ROM.

Upgrade backup software
It is important to check http://w ww.hp.com/go/connect for software compatibility and install any
recommended upgrades.
NOTE:
Certain backup applications require you to use their own Tape driver instead of the HP Ultrium Tape
driver.
For optimum performance it is important to use a backup application that is appropriate for your system’s
configuration. In a direct attach configuration, where the tape drive is attached to a standalone server,
you can use backup software that is designed for a single server environment. In network configurations
you will need backup software that supports enterprise environments. HP, Symantec, Legato, Yosemite
and Computer Associates all provide suitable products. Further details about these and other products
that may be appropriate c an be found on our connectivity web site.
1. Go to our connectivity web site: h
2. Select software compatibility.
3. Select your combination of operating system and tape drive model in the table. A list of supported
backup applications is displayed. This will also tell you whether your configuration is compatible
with HP One-Button Disaster Recovery, HP OBDR. (All HP StorageWorks DAT tape drives support HP
OBDR. However, you can only use this feature if your system configuration and backup application
also support it. See “Using HP OBDR” on page 45.)
4. Make sure you have a backup application that supports HP StorageWorks DAT tape drives and
download any upgrades or patches, if required.
