How do I connect the drive to my server?

The following guidelines apply:

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

controller on your server and a suitably-rated SCSI cable.

drive should only be connected to an Ultra 160 or Ultra 320 host bus adapter or SCSI controller.

also ”Why is the SCSI bus type important?” on page 10.

• For optimum performance the drive should be the only device on the SCSI bus. Do not connect

more than two tape drives per SCSI controller.

• Always terminate the SCSI bus.

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

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

Internal drives

The tape drive is installed into a spare drive bay in your server (or into an HP Rack-Mount Option Kit) and is attached to the SCSI bus of the host server. Use an LVDS-compatible ribbon cable to connect the tape drive to a spare 68-pin, high density (HD), wide SCSI connector on the host server. For most servers we recommend that you use the terminated SCSI ribbon cable supplied with the drive.

You need one industry-standard, 5¼-inch, half-height bay in which to install the HP StorageWorks DLT VS160 tape drive.

For optimum performance your tape

External drives:

Your tape drive is supplied with a 68-pin, wide, VHDCI-to-HD SCSI cable to attach to the host server. See also ”Installing an external DLT VS160 tape drive” on page 29.

Check the usage models on ”Usage models” on page 12. This shows how the HP StorageWorks DLT VS160 tape drive can be used in different system architectures.

Why is the SCSI bus type important?

The SCSI bus type determines the speed at which data can be transferred between devices on the bus and the maximum length of cable that can be used. The drives support a burst transfer rate of 160 MB/sec. To benefit from this level of performance, it is important to ensure that the drives are connected to a SCSI bus of a similar or higher specification. This means that you need:

• An Ultra160 or Ultra320 SCSI bus.

second; Ultra320 SCSI exceeds this.

• LVD-rated SCSI cabling and terminators. The LVD interface enables the data to be transferred at

the drive's maximum rate and provide a maximum cable length of 12 meters.

Ultra160 SCSI supports the maximum bus speed of 160 MB per

Before you start10

If you attach the drive to a lower specification SCSI bus, it may still work, but data will not be transferred as quickly. For example, on a single-ended (SE) Ultra 2 SCSI bus the maximum burst transfer speed of the drive is 40 MB/second and the maximum cable length is restricted to 3 meters.

NOTE: The drives are not compatible with high voltage differential (HVD) SCSI devices.

Table 1 Supported SCSI bus types

Ultra320 LVD Yes. This is a recommended configuration.

Do not daisy chain with Ultra320 devices.

Ultra160 LVD Yes. This is a recommended configuration.

Up to two devices may be daisy chained.

Ultra2 LVD Yes. This is acceptable for one DLT VS160 drive per bus.

Ultra wide LVD and single-ended

Ultra narrow, single-ended

High Voltage Differential

These are not recommended configurations as they will restrict performance.

No. This will severely restrict performance and you will need a suitable cable or adapter.

No. The drive will not work and you may damage the drive or controller

How can I check the SCSI bus type and SCSI ID?

For many operating systems, you can install and run HP Library & Tape Tools from either the HP StorageWorks Tape CD-ROM or www.hp.com/support/tapetools SCSI configuration (see also ”Diagnostic tools” on page 47). This will provide information about the SCSI bus and the SCSI IDs in use.

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, an installation check, and performance

information and tools

• Learn about your product

• Register your product

• Buy media online

• Troubleshoot with HP Library & Tape Tools.

Usage models

HP StorageWorks DLT VS160 tape drives can be used in a stand-alone or network environment. However, they should always be directly attached to a suitably-rated SCSI connector on the storage server.

Figure 2 Usage model

AServer

BTape drive

Before you start12

The following table shows the recommended usage models and ”Optimizing performance” on page 48 provides further information about factors that can affect performance.

Table 2 Recommended usage models

Direct Attach, single storage server

DLT VS160

A RAID disk subsystem is recommended for all usage models.

A single disk, particularly a fast disk such as a 15K RPM drive, will also be sufficient for DLT VS160 tape drives, but be aware of other factors that can affect performance—such as, compressibility of data, disk fragmentation and the number of files. See also ”Optimizing performance” on page 48.

You can use our free performance assessment tools, which are available stand-alone 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.

Recommended Recommended, anything less than Gigabit Ethernet

Across the Network, single storage server, multiple clients

may limit performance

Other usage 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 stand-alone DLT VS160 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 configurations.

2 Drivers and backup software

Install drivers

Installing on Windows

The driver available from Microsoft update is acceptable, but the HP driver provides better support for all the features of your new tape drive. It is regularly updated and is available on the HP StorageWorks CD-ROM or on the HP Support web site at www.hp.com/support

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 ”Troubleshooting with Library

& Tape Tools” on page 47). 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.

Installing on UNIX

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 or configure device files.

Installing on IA64

If you are installing on an IA64 system, such as an HP Integrity server, check

www.hp.com/go/connect

upgrades and drivers.

for the latest information on the availability of backup application

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.

Drivers and backup software16

3 Installing an internal DLT VS160 tape drive

If you are installing an external DLT VS160 tape drive, please refer to Chapter 4.

Mounting bay

You need one industry-standard, 5¼-inch, half-height bay in which to install the HP StorageWorks DLT VS160 tape drive.

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.

Air flow requirements

The server must provide forced cooling and be capable of drawing 3 cfm (0.08 m3/minute or 5.1

/hour) of air through the tape drive at 40o C ambient operation. Always operate the tape drive

within an ambient air temperature of no more than 40

It is important to keep the cooling holes in the rear and the grill in the front of the tape drive clear of any obstructions that may hinder the air flow and to ensure that all fans in your server are in place and operational. Make sure that empty bays have the appropriate blanking plates installed so that airflow is maintained.

Your HP StorageWorks DLT VS160 drive is shipped with a default SCSI ID of 6. Each device on the SCSI bus must have an unique SCSI ID number. The drive can be assigned any unused ID between 0 and 15. Do not use SCSI ID 7, which is reserved for the SCSI controller. SCSI ID 0 is typically assigned to the boot disk and should also not be used unless the tape drive is on a dedicated SCSI bus.

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

wriststrap if possible. If not, to equalize the electromagnetic charges, touch a bare metal part of the server (such as the back plate) before you remove the tape drive from its bag.

Figure 3 Checking the SCSI ID

1. Determine whether you need to change the SCSI ID from the default of 6.

For most operating systems you can run HP Library & Tape Tools to check your server’s current SCSI configuration (see ”Diagnostic tools” on page 47). This will provide information about the SCSI bus and the SCSI IDs in use. See also ”Troubleshooting with Library & Tape Tools” on page 47.

2. Change the tape drive’s SCSI ID, if necessary.

The SCSI ID is set using jumpers on a set of pins at the rear of the drive, as shown in Figure 3. Use tweezers or small pliers to move the jumpers to the pattern corresponding to the ID you want. Spare jumpers are provided with the drive.

Prepare mounting bay

WARNING! 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.

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.

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.
