DDS models

This guide describes how to install and operate the following DDS internal tape drive models:

•DAT72

•DDS-4

Which operating systems are supported?

DDS drives can be connected to servers running under Windows®, NetWare, UNIX, Tru64, Linux and .net. Refer to the manufacturer’s web site for more information.

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 your disk drive or to a RAID controller, unless your configuration supports Tape-on-RAID.

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 7. The cable must be terminated, see “Step 7: 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 or 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.

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 DDS tape drive. It can also be installed in a 3½-inch bay using the supplied conversion kit (see page 15). 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.

Some servers require a special mounting tray or rails to fix the drive into the empty bay. 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. You may also be able to order mounting hardware for some servers through your tape drive supplier.

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. (If you install in a 32-bit PCI expansion slot, performance may be degraded.)

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 and Computer Associates all provide suitable products. Further details about these and other products that may be appropriate can be found on the supplier’s web site.

Make sure you have a backup application that supports DDS tape drives and download any upgrades or patches, if required.

Drivers

Windows users

Before you install the tape drive, download the driver from the supplier’s web site. Refer to the accompanying README file for specific installation instructions for Windows NT, Windows 98, Windows 2000, Windows ME and Windows XP drivers. This will tell you whether you need to install the driver before or after installing the tape drive.

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.

IA64 users

If you are installing on IA64, check your supplier’s web site for the latest information on the availability of backup application upgrades and drivers.

Figure 1: checking the SCSI connection

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.

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, unless your configuration supports Tapeon-RAID, or the same SCSI bus as your disk drive.

Yes

4 You are ready to install the

drive.

Check them now.

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.

Ultra 2 LVD, Ultra 3 (160) LVD, Ultra 4 (320) LVD

Ultra narrow, single-ended Yes. But this is not recommended as it will severely restrict

High Voltage Differential No. The drive will not work and you may damage the drive or

Figure 2: checking the SCSI ID

Step 1: Check the drive’s SCSI ID

Your DDS drive is shipped with a default SCSI ID of 3. Each device on the SCSI bus must have a 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.

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 2. Use tweezers or small pliers to move the jumpers to the pattern corresponding to the ID you want. Do not remove the TERM PWR jumper. It should always be set.

Spare jumpers will be attached to the drive.

Figure 3: setting the UNIX configuration switches

Step 2: Set the configuration switches (UNIX systems)

This section applies to UNIX systems only. If you are installing a tape drive on a PC system go to “Step 3: Prepare the mounting bay” on page 13.

1 If you are installing a tape drive on a UNIX system, you may also need to change the

configuration switches, which are located on the underside of the drive. The following table summarizes the typical switch settings for different types of server.

Switch Number

System Type 12345678

Default and most PC systems HP Alpha systems HP-UX systems IBM RS/6000 systems SCO/PC UNIX systems Silicon Graphics systems Sun systems

2 If your UNIX configuration requires it, change the configuration switches located on the

underside of the drive from the default settings shown in figure 3.
