HP StorageWorks DAT models

This guide describes how to install and operate the following HP StorageWorks DAT USB tape drive models:

•HP StorageWorks DAT 160

•HP StorageWorks DAT 40

•HP StorageWorks DAT 24

For a detailed product specification, please refer to our World Wide Web site (http://www.hp.com).

Which operating systems are supported?

HP StorageWorks DAT USB drives can be connected to servers running under Microsoft Windows Server 2000, Server 2003, XP Professional and Linux Kernels 2.6.x. Refer to the HP StorageWorks Tape Software Compatibility topic on our World Wide Web site (http://www.hp.com/go/connect/) for the most recent information about the operating system versions that are supported.

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. Although the tape drive will function on USB 1.1, performance will be severely degraded. See also “Verifying USB installation for optimum performance” on page 52. Appropriate USB cables are supplied with your tape drive.

For internal drives, the USB 2.0 connection may be via an internal port on the server’s system board (as in many newer ProLiants servers) or an external port on the server’s rear panel.

14 Before you start

What are the mounting requirements for an internal tape drive?

Mounting bay

You need one industry-standard, 5¼-inch, half-height bay in which to install the HP StorageWorks DAT tape drive. Power requirements are:

Table 2 Power requirements

Voltage		Typical Current			Maximum Current
	DAT 160		DAT 72/40/24		DAT 160	DAT 72/40/24
5 V	1.54	A	0.7	A	1.61 A	0.8	A
12 V	0.26	A	0.3	A	1.3 A	1.0	A

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 for a number of industry-standard servers may be available. For more details refer to: http://www.hp.com/go/connect.

Some servers use non-standard mounting 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.

Using the HP StorageWorks Tape CD-ROM

The HP StorageWorks Tape CD-ROM is a central source of information about your tape drive with utilities for getting the best performance from your tape drive.

Use the HP StorageWorks Tape CD-ROM to check installation, as described in this guide, and to verify and troubleshoot performance after installation. It helps you to:

•Install your product, which includes access to drivers, and performance information and tools

•Learn about your product

•Register your product

•Buy media online

•Troubleshoot with HP Library & Tape Tools.

2 Drivers and backup software

Install drivers

Installing on Windows

Two drivers are required in order to use HP StorageWorks DAT USB tape drives.

•hpdat: This is the tape driver that works with all HP DAT products. It is regularly updated and is 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.

The CD contains a driver install package for the following Microsoft Windows operating systems: Windows Server 2000, Windows Server 2003 and Windows XP. If you prefer to use Windows Device Manager to install the tape drivers manually, you will find them in the drivers directory on the CD-ROM.

IMPORTANT:

We strongly recommend that you use the installer package on the HP StorageWorks CD-ROM to install the drivers BEFORE you connect the tape drive.

Updates to the drivers may be provided from time to time on the HP support web site (http://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

If you have not already installed drivers, the Windows Found New Hardware wizard may run when you 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.

2.Select the install drivers link on the CD-ROM.

3.Run the automated installer and follow the process to load the two drivers onto the system.

4.On completion of the installation the tape drive will be ready to use.

Installing on Linux

The Linux operating system also requires two drivers. These drivers are included with the operating system and should be loaded automatically. See also “Check drivers (Linux)” on page 54.

Upgrade backup software

It is important to check http://www.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 can be found on our connectivity web site.

1.Go to our connectivity web site: http://www.hp.com/go/connect and select tape backup.

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.
