Before you start

HP StorageWorks Ultrium tape drives are high-performance Ultra 160 SCSI half-height

devices with a maximum burst transfer speed of 160 MB/second. They are designed to

operate on a low voltage differential SCSI bus (LVDS). They should be connected to a VHD

SCSI connection on your storage server. For a detailed product specification, please refer to

our World Wide Web site (www.hp.com).

Before starting to install your tape drive, you should consider the following:

Which operating systems are supported?

HP StorageWorks Ultrium drives can be connected to servers running under Windows®,

NetWare, HP-UX, Tru64, Linux and several other industry-standard operating systems. Refer to

the “HP StorageWorks Tape Software Compatibility” topic on our World Wide Web site

(www.hp.com/go/connect) for more information about the operating systems and

versions that are supported.

How do I connect the drive to my server?

Check the usage models on page 6. This shows how the HP StorageWorks Ultrium tape drive

can be used in different system architectures.

Your tape drive is supplied with a 68-pin, wide, VHD-to-HD SCSI cable to attach to the host

server.

You will need a properly installed and configured SCSI host bus adapter (HBA) or a built-in

SCSI controller on your server with a spare LVD SCSI port with a 68-pin, very high density

(VHD), wide SCSI connector.

For optimum performance your tape drive should only be connected to a SCSI bus that can

transfer data at a rate that supports the tape drive’s maximum burst transfer speed, see

Table 2, “supported SCSI bus types,” on page 11, and it should be the only device on the

SCSI bus. Do not attach the drive to the same SCSI bus as your disk drive or RAID controller

(unless you are connecting to a ProLiant server with a Smart Array 6i RAID controller).

How can I check the SCSI bus?

We strongly recommend that you use HP Library & Tape Tools to check your server’s current

SCSI configuration (see)“Step 2: Check the drive’s SCSI ID” on page 13. This will provide

information about the SCSI bus and the SCSI IDs in use.

HP Library & Tape Tools is the recommended diagnostic and support tool for your HP tape

storage product. It is available on the CD shipped with your product or as a free download

from the HP web site and is supported on nearly all major operating systems.

See www.hp.com/support/tapetools for compatibility information, updates and the

latest version of the tool.

Do I need additional items for installation?

• If the tape drive is not the only or last device on the SCSI bus, you must terminate the bus

with a multimode terminator. If the tape drive is the only or last device on the bus, then the

tape drive enclosure provides active termination and you do not need to purchase a

separate terminator.

• If you do not have a VHD, wide SCSI connector on your server, you will need to purchase

and install a VHD-to-HD adapter or use an HD-to-HD cable instead of the supplied cable.

• If you do not have a spare, suitably rated SCSI connector on your server, you must install a

new HBA (also known as a SCSI card). The SCSI bus rating should match or be higher than

the SCSI rating of your tape drive. See Table 2, “supported SCSI bus types,” on page 11

for recommended HBAs. For specific details relevant to your server model please refer to

www.hp.com/go/connect. You will need to purchase and install the new HBA into an

unused, 64-bit PCI expansion slot within your server before installing your tape drive. (The

kit can also be installed in a 32-bit PCI expansion slot, but this may limit performance.)

Refer to our World Wide Web site for recommended products, configurations and ordering

information: www.hp.com/go/connect or www.hp.com/support/ultrium.

Backup software and drivers

Backup software

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, Yosemite, Legato 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.

1Go to our connectivity web site: www.hp.com/go/connect.

2Select software compatibility.

3Select 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 Ultrium

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 27.)

4Make sure you have a backup application that supports your HP StorageWorks Ultrium tape

drive and download any upgrades or patches, if required.

Drivers

Windows users

The driver available from Microsoft update is acceptable, but the HP driver (available on the

CD-ROM or the web) provides better support for all the features of your new tape drive.

After you connect the tape drive, insert the HP StorageWorks Tape CD-ROM and follow the

link to download the HP driver from our web site: www.hp.com/support, see “Step 5:

Verify installation” on page 19. Refer to the accompanying README file for specific

installation instructions for Windows 2000, Windows XP and Windows Server 2003 drivers.

Note: We recommend that you install drivers from the web link on the CD-ROM rather than

the Windows Hardware Installation Wizard, because you can also use HP Library & Tape

Tools software on the CD-ROM to verify that your installation is correct (see “Step 5: Verify

installation” on page 19). If you do not have internet access, you can also install drivers

directly from the HP StorageWorks Tape CD-ROM, but these may not be the latest versions

available.

UNIX users

The recommended backup applications use the operating system’s standard, built-in device

drivers. To upgrade drivers we recommend that you patch to the latest version of the operating

system, following the instructions in the patch documentation. You will also find information

about configuring device files in the UNIX Configuration Guides on the CD-ROM.

page 7

Usage models

The tape drive (B) can be used in a standalone or network environment. It should always be

directly attached to a VHD SCSI connector on the storage server (A), as shown in Figure 1.

Recommended models

The following table shows the recommended usage models and “Optimizing performance”

on page 32 provides further information about factors that can affect performance.

table 1: recommended usage models

A RAID disk subsystem is recommended, especially for Ultrium 448 drives. A single disk,

particularly a fast disk such as a 15K RPM drive, will also be sufficient, but be aware of other

factors that can affect performance—such as, compressibility of data, disk fragmentation and

the number of files. You can use our free performance assessment tools, which are available

standalone or integrated into HP Library & Tape Tools, to check tape performance and test

whether your disk subsystem can supply data at the optimum transfer rate. You can also use

these tools to calibrate your restore performance and maximal tape performance with more

compressible data.

Other models

The tape drive may work with other usage models, such as network attach storage (NAS) and

storage area networks (SAN), but HP does not currently provide technical support for

installing and using standalone Ultrium tape drives with these architectures. Similarly,

connection to fibre channel may be possible, if you purchase and install a fibre channel/SCSI

bridge, but it is not currently a supported option.

Please check www.hp.com/go/connect for the latest supported configurations.
