HP StorageWorks DAT models

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

•HPStorageWorksDAT72

•HPStorageWorksDAT40

Which operating systems are supported?

HP StorageWorks DAT drives can be connected to servers running under Windows®, NetWare, UNIX, Tru64 and Linux. Refer to the “HP StorageWorks Tape Software Compatibility” topic on our World Wide Web site ( information about the operating system versions that are supported.

How do I connect the drive to my server?

The following guidelines apply:

• For optimum performance the drive should be the only device on the SCSI bus.

• Always terminate the SCSI bus.

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

www.hp.com/go/connect) for more

You will need a properly installed and configured SCSI host bus adapter (HBA) or a built-in SCSI controller on your server. Your tape drive is attached to the SCSI bus of the host server via a spare connection on the internal SCSI ribbon cable. The cable should be compatible with low voltage differential SCSI (LVDS) and it should have a spare 68-pin, high density (HD), wide SCSI connector. See “Checking the SCSI connection” on page 9. The cable must be terminated, see “Step 6: Attach power and SCSI cables” on page 21.

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 40 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 Ultra Wide, Ultra2 Wide, Ultra3 (160) or Ultra4 (320) SCSI bus. Ultra Wide SCSI

supports the maximum bus speed of 40 MB per second, Ultra2, Ultra3 and Ultra4 SCSI exceeds this.

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

transferred at the drive's maximum rate.

If you attach the drive to a lower specification SCSI bus, it may still work but data will not be transferred as quickly.

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

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

For many operating systems, you can install HP Library & Tape Tools from www.hp.com/

support/tapetools

configuration (see page 35). This will provide information about the SCSI bus and the SCSI IDs in use. See also the SCSI topic in the electronic User’s Guide on the HP StorageWorks Tape CD-ROM for other ways of checking the SCSI bus type.

and run the “Install Check” to check your server’s current SCSI

What are the mounting requirements for the 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:

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.

Do I need additional items for installation?

• You may need mounting hardware. See “What are the mounting requirements for the tape drive?” above.

• 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). This should be of an Ultra Wide or higher SCSI specification. 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 performance may be degraded.)

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

www.hp.com/go/connect or www.hp.com/support.

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, 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.

Windows NT, Windows 2000, Windows XP and Windows Server 2003 drivers. This will tell you whether you need to install the driver before or after installing the tape drive.

If you do not have internet access, you can also download drivers 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 or configure device files, as described in the UNIX Configuration Guide on the CDROM.

Checking the SCSI connection

Use the following questions to help you check your SCSI connection. As long as you have a spare drive bay in your server you should have a spare connection on the internal SCSI bus. You need to ensure it is the correct SCSI bus type. If you answer ‘Yes’ to all these questions, you are ready to install your tape drive. If you answer ‘No’, you will probably need to purchase and install additional items. For compatibility and product details, go to

www.hp.com/go/connect.

1 Have you checked the SCSI

bus type and SCSI IDs in use?

Yes

2 Is the SCSI bus type correct

for the SCSI specification of the drive?

Yes

3 Will the drive be the only

device on the bus? This is the recommended configuration. Do not connect to a RAID controller or the same SCSI bus as your disk drive.

Yes

4 You are ready to install the

drive.

Users of most operating systems can use HP Library & Tape Tools to do this. The SCSI topic in the online User’s Guide provides further advice on identifying SCSI IDs.

See table below. If the SCSI bus differs from the recommended specification for the drive, performance of either the drive or the bus may be impaired. Consider replacing your card with one of the recommended HBAs.

If you have an Ultra HBA, performance may be impaired. Consider installing (if you have a spare PCI slot) or replacing your card with an Ultra 2, Ultra 3 (160) or Ultra 4 (320) HBA.

SCSI Bus Type Supported

Ultra wide LVD Yes. This is a recommended configuration as long as the drive is

the only device on the SCSI bus.

Figure 3: checking the SCSI ID

Step 1: Check the drive’s SCSI ID

Your HP StorageWorks DAT drive is shipped with a default SCSI ID of 3. 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.

1 Determine whether you need to change the SCSI ID from the default of 3.

For many operating systems you can install HP Library & Tape Tools from the HP StorageWorks Tape CD-ROM and run the “Install Check” to check your server’s current SCSI configuration (see page 35). This will provide information about the SCSI bus and the SCSI IDs in use.

The UNIX Configuration Guide on the HP StorageWorks Tape CD-ROM also contains instructions on how to determine the SCSI IDs of existing devices on UNIX servers.

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. Do not remove the TP jumper. It should always be set.

Spare jumpers will be attached to the drive.
