2DDS Gen 5 Tape Drive: User’s Guide

Chapter 2. Installation
This chapter describes how to install the internal DDS Gen 5 drive.
Unpacking
Before you unpack the contents of your drive package, inspect the shipping
containers for damage. If you spot damage to the container, notify your carrier
immediately.
When you unpack the package, compare the items received with those on the
packing list. If any item is missing or damaged, please contact your place of
purchase immediately.
Pre-installation requirements
In addition to the contents included with your internal tape drive, you need the
following items to install your internal tape drive.
vA SCSI host bus adapter that is properly installed and configured in a host
computer
vA 3.5-inch or 5.25-inch half-height bay
vBackup application software that supports the internal tape drive.
vPhillips screwdriver
vFlatblade screwdriver, if your computer uses flathead screws
vTorx screwdriver, if your computer uses torx screws
Avoiding electrostatic damage
Your internal tape drive has very sensitive components that are prone to damage
from electrostatic discharge (ESD). Use extreme care when handling the drive, as it
can be damaged by ESD.
Before handling the drive, read these ESD instructions to prevent damage to the
drive.
vWear an ESD-preventive grounding wrist strap or observe similar ESD
precautions when working with the drive. Be sure the wrist strap makes good
skin contact. Do not remove the wrist strap until you finish working with the
drive.
vAvoid contact between the drive, other equipment, and clothing. The wrist strap
only protects the equipment from ESD voltages on the body; ESD voltages on
clothing can still cause damage.
vWhen the drive is not being used, keep it in its antistatic bag.
vBefore you remove the drive from the antistatic bag, touch a metal or grounded
surface to discharge any static electricity buildup from your body.
vHold the drive by its edges only. Avoid touching any exposed parts on the
printed circuit board.
vAlways place the drive on top of or inside the antistatic bag to reduce the
chance of ESD damage.

Reviewing drive default settings
Your internal tape drive comes with various default settings. These settings are
configured using jumpers and switches.
vThe jumpers are located on the back of the drive, between the SCSI interface and
power connectors (refer to the diagram in“General installation instructions” on
page 9).
vThe switches are located on the underside of the drive. If you change a switch
setting, you must turn the drive off and then on to have the new setting take
effect (see Figure below).
You may need to change these settings to suit your requirements. Review the
default settings shown below to determine whether they suit your requirements or
need to be changed.

SCSI ID settings
Jumper Pins: 1-2, 3-4, 5-6, 7-8
Default Settings: SCSI ID 6
Each SCSI device on the bus must have its own unique ID. Your internal tape
drive is shipped with a default SCSI ID of 6. If another SCSI device in the SCSI
chain is already using this ID, use jumper pins 1–2, 3–4, 5–6, and 7–8 to change the
drive’s SCSI ID.
Note: If you change the drive’s default SCSI ID, avoid using SCSI IDs 0 and 1
(which typically are assigned to a boot drive) and SCSI ID 7 (which typically is
assigned to SCSI controllers or host bus adapters).
Parity checking
Jumper Pins 9-10: Pins 9-10 shunted: Enable parity checking
(default)
Pins 9-10 open: Disable parity checking
By default, parity checking is enabled on the internal tape drive. To disable parity
checking, remove the jumper from pins 9 and 10.
Note: If you disable parity checking, the drive still generates a parity bit.
Terminating power
Jumper Pins 11-12: Pins 11-12 shunted: Enable terminator
power
Pins 11-12 open: Disable terminator power
(default)
By default, terminator power is disabled on the internal tape drive. To enable
terminator power, place a jumper across pins 11 and 12.
Note: If you enable terminator power, be careful not to short the TERMPWR signal
to ground (for example, by attaching the SCSI cable upside down). If a short
Chapter 2. Installation 5

occurs, terminator power to the bus is interrupted. After the short is removed, a
fuse in the drive is automatically reset, restoring terminator power.
Data compression
Settings: Switch 1 ON = Enable hardware data
compression (default)
Switch 1 OFF = Disable hardware data
compression
Switch 2 OFF = Recognize SCSI data
compression commands (default)
Switch 2 ON = Ignore SCSI data
compression commands
The internal tape drive provides two switches for controlling data compression.
Switch 1 determines whether hardware data compression is enable or disabled. By
default, switch 1 is set to ON, enabling hardware data compression. To disable
hardware data compression, set switch 1 to the OFF position.
Switch 2 controls whether SCSI commands are recognized for enabling or disabling
hardware data compression. By default, switch 2 is set to ON, allowing SCSI
commands to be used to enable or disable hardware data compression. To prevent
SCSI commands from enabling or disabling hardware data compression, set switch
2 to the OFF position.
When data compression is enabled, the drive compresses all data written to tape
and decompresses all compressed data read from tape. The degree of compression
varies due to the type of data being processed.
vData with a high degree of redundancy, such as structured database files or
graphics files, are compressed most efficiently, often at a ratio of 2:1 or more.
vData with little redundancy, such as executable programs, are compressed the
least.
Power-on self test
Settings: Switch 4 ON = Drive performs Power-On
Self Test (default)
Switch 4 OFF = Drive does not perform
Power-On Self Test
Switch 4 enables or disables the Power-On Self-Test diagnostics that the drive
performs when powered on. By default, the drive responds to SCSI commands
only after it successfully completes the Power-On Self-Test (about 5 seconds). To
prevent the drive from performing the Power-On Self-Test when powered-up, set
switch 4 to the OFF position.
Host operating system
Switches: 5,6,7,8
Default Settings: Microsoft Windows
6DDS Gen 5 Tape Drive: User’s Guide

Switches 5 through 8 configure the internal tape drive for a host operating system.
By default, these switches are all ON. This setting configures the drive for a

2. Remove the computer’s power cord from the computer connector.
3. Remove the computer cover. For more information, refer to the documentation
that came with your computer.
Note: If you have to disconnect cables to gain access to the mounting bay, note
which cables were removed. You can then refer to this information when you
reconnect the cables at the end of this procedure.
4. Select an available 3.5-inch or 5.25-inch mounting bay, depending the internal
tape drive you want to install.
Note: The internal tape drive can be mounted horizontally or vertically (on its
side).
5. If the mounting bay has a “filler panel,” remove it according to the instructions
in your computer’s documentation. Place the screws aside, You will need them
to secure the drive in the bay.
6. If the computer does not have a SCSI host adapter, install one.
8DDS Gen 5 Tape Drive: User’s Guide

Installing the drive
This section contains information on installing the tape drive in IBM servers and
other computers.
Installing the drive in IBM servers
The IBM DDS Gen 5 Tape Drive can be installed in several IBM xSeries servers.
The most current list of supported servers can be found at
www/pc/ibm.com/us/compat/storage/matrix.html. Refer to the documentation
that comes with the server for instructions on installing the tape drive or follow
the general instructions below.
General installation instructions
Follow these steps to install the tape drive.
Step 1. Selecting a SCSI ID
Each device on a SCSI bus must have a unique SCSI ID. Select a SCSI ID from 0 to
15 for the tape drive. The SCSI ID must be supported by your SCSI adapter. Refer
to your SCSI adapter documentation for the range and relative priority of the IDs
supported. The tape drive is shipped with the SCSI ID preset to 6.
Follow these guidelines to select a SCSI ID:
vAssign the tape drive to one of the higher priority IDs available (0–6).
vAssign the lower priority ID numbers (8-15) to those devices that are most often
used or are faster than other devices in the chain.
vDo not assign an ID of 7, because this is usually used as the SCSI adapter ID.
Depending on your computer, there are several ways to view your current SCSI ID
settings:
vFor many IBM computers, press F1 during the startup after the memory check
completes. Other adapters show SCSI settings when you press Ctrl A. Check the
documentation that comes with your computer or SCSI adapter for information
on how to view configuration information.
vUse SCSI adapter utility programs, if available.
vInspect the installed SCSI devices to see how the jumpers that determine the IDs
are set.
Step 2. Setting the SCSI ID
Chapter 2. Installation 9

Refer to the following diagram when setting the SCSI ID.
SCSI ID=0
SCSI ID=1
SCSI ID=2

3-4 SCSI ID bit 1
5-6 SCSI ID bit 2
7-8 SCSI ID bit 3
9-10 Parity checking
11-12 Termination Power
Note: When setting the SCSI ID, use the jumpers that come with the tape drive. If
your enclosure uses a remote SCSI ID switch, remove the jumpers from the jumper
pins on the tape drive and connect the remote switch.
1. Find the jumper pin setting that corresponds to the SCSI ID number you
choose; then place jumper pins on the SCSI ID blocks as shown. You can use a
pair of flat-nose pliers to place the jumpers on the jumper pins.
Step 3. Mounting the drive
Mount the tape drive; then attach the SCSI and power cables to it. If there is
insufficient working space to attach the connectors after mounting the drive, attach
the cables first. To mount the drive, follow these steps:
