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 (www.hp.com/go/connect most recent information about the operating system versions that are supported.

HP StorageWorks DAT Tape Drives User Guide 7

) for the

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 42. Appropriate USB cables are supplied with your tape drive.

NOTE: 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.

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 1 Power requirements

Voltage Typical Current Maximum Current

5 V 3.5 A 4.0 A

12 V 0.3 A 1.7 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:

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.

Before you start8

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.

IMPORTANT: We strongly recommend that you use the installer package on the HP StorageWorks

CD-ROM to install the two drivers BEFORE you connect the tape drive.

Updates to the drivers may be provided from time to time on the HP support web site (www.hp.com/support 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.

). We recommend that these are installed after using the installer on the

When you attach or install the tape drive connecting to a USB 2.0 port, as described in this guide, and switch it on, the tape drive will be detected automatically and the correct drivers 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 43.

HP StorageWorks DAT Tape Drives User Guide 9

Upgrade backup software

It is important to check www.hp.com/go/connect for software compatibility and install any recommended upgrades.

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, Veritas, 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: www.hp.com/go/connect

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 35.)

4. Make sure you have a backup application that supports HP StorageWorks DAT tape drives and

download any upgrades or patches, if required.

and select tape backup.

3 Installing an internal DAT tape drive

If you are installing an external DAT tape drive, please refer to Chapter 4.

NOTE: It is important to ensure that you connect your drive to a USB 2.0 port. The drive will work

on a USB 1.1 port but performance will be severely degraded. See also ”Verifying USB installation

for optimum performance” on page 42.

Prepare mounting bay

CAUTION: To avoid personal injury or damage to the server or tape drive, ensure that the server is

disconnected from the mains power supply while you install the drive.

1. Assemble the necessary tools and materials:

• Phillips screwdriver

• Flat-bladed screwdriver (if your server uses slotted screws)

• Torx screwdriver (if your server uses torx screws)

• Your server manuals (for reference during installation)

2. Perform a normal system shutdown and turn off the server and any connected peripherals.

3. Remove the cover and front panel from the server, as detailed in your server’s documentation.

As you work inside the server, you may have to disconnect other signal cables or power cables from other devices to maneuver the new drive into place. If you have to do this, make a note of their position and connections so you can put them back correctly later.

documentation. Keep any screws for use in ”Secure the drive” on page 21.

5. You are now ready to install your tape drive.

Installing an internal DAT tape drive12

Attach mounting hardware

If your server requires special rails or other hardware to install the tape drive, mount them on the tape drive now. If your server does not require special mounting hardware, proceed to ”Install drive”

on page 16 now.

CAUTION: Static electricity can damage electronic components. Always wear an antistatic

wriststrap if one is available. If not, after you have disconnected power from the server and removed the cover, touch a bare metal part of the chassis. Similarly, touch a bare metal part of the drive before installing it.

HP ProLiant servers

NOTE: If mounting hardware is supplied with your tape drive, it may not be exactly the same as

shown in the illustrations.

Different models of server require different mounting methods. The server may also incorporate a locking mechanism to hold the tape drive in place. See ”Secure the drive” on page 21.

Please check your HP ProLiant server documentation to ascertain the correct method of mounting, and to check whether mounting hardware is provided with the server.

HP StorageWorks DAT Tape Drives User Guide 13

Mounting rails

Some HP ProLiant servers, such as ML530 and ML570, require mounting rails. These may be metal or plastic rails attached to the filler panel of the server's drive bay.

1. Use a regular Phillips screwdriver to attach the appropriate rails. Use the M3 screws provided

with the tape drive, as shown in Figure 4. Ensure you do use the M3 screws provided. The rails may be attached to the filler panel by

screws of a different thread/size type and these should not be used. If in doubt, refer to your HP ProLiant server documentation.
