Safety Information
DANGER
An electrical outlet that is not correctly wired could place hazardous voltage
on metal parts of the system or the devices that attach to the system. It is the
responsibility of the customer to ensure that the outlet is correctly wired and
grounded to prevent an electrical shock.
Before installing or removing signal cables, ensure that the power cables for
the system unit and all attached devices are unplugged.
When adding or removing any additional devices to or from the system,
ensure that the power cables for those devices are unplugged before the
signal cables are connected. If possible, disconnect all power cables from the
existing system before you add a device.
Use one hand, when possible, to connect or disconnect signal cables to
prevent a possible shock from touching two surfaces with different electrical
potentials.
During an electrical storm, do not connect cables for display stations, printers,
telephones, or station protectors for communication lines.

Handling Static-Sensitive Devices
Attention: Static electricity can damage the device and your system unit. To avoid
damage, keep this device in its anti-static protective bag until you are ready to install it.
To reduce the possibility of electrostatic discharge, follow the precautions listed below:
v Limit your movement. Movement can cause static electricity to build up around you.
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v Do not leave the device where others can handle and possibly damage the device.
v While the tape drive is still in its anti-static package, touch it to an unpainted metal
part of the system unit for at least two seconds. (This drains static electricity from the
package and from your body.)
v Remove the device from its package and install it directly into your system unit
without setting it down. If it is necessary to set the device down, place it on its
static-protective package. (If your device is an adapter, place it component-side up.)
Do not place the device on your system unit cover or on a metal table.
v Take additional care when handling devices during cold weather, as heating reduces
indoor humidity and increases static electricity.

The 20/40GB 4MM Internal Tape Drive is an internal streaming tape drive that provides
medium- to high-capacity backup and archival capability, as well as a high data-transfer
rate. The 20/40GB 4MM Internal Tape Drive uses wide bus (16-bit) architecture.
Communications on the SCSI bus can be either asynchronous or synchronous. The
20/40GB 4MM Internal Tape Drive is compatible with existing 4.0 GB, and 12.0 GB
4mm tape cartridges. The 20/40GB 4MM Internal Tape Drive can be used as a boot
device.
Note: This device is available as an auto-docking feature on some systems. See your
system documentation for information about the auto-docking feature.
The tape drive is used primarily for:
v Saving and restoring system data files
v Archiving important records
v Distributing operating system software upgrades
The drive conforms to the American National Standards Institute (ANSI) SCSI-2
standard. You can attach the drive to any system that uses a single-ended
interface/LVD that meets SCSI-2 Standard ANSI X3.131-1994.Rev 10h.
The 20/40GB 4MM Internal Tape Drive features include:
v Use of 20/40 GB 4-mm data cartridges
v Data rate of 3.0 MB per second
v Capacity of 20 GB
v Compression capability, which effectively doubles the native capacity of 20 GB and
the effective data rate. The actual capacity per cartridge varies depending on the
application and the type of data cartridge being used. The default is compressed.
Use the System Management Interface Tool (SMIT) to change the default.
Note: The factory default setting is
Activated
. Data compression is usually controlled
by the application software.

Tape Drive Environment and Use
Tape drives require specific maintenance and environmental conditions to operate well
over time. Using high-quality, data-grade media, handling and storing this media
properly, operating the tape drive in a clean environment and keeping the tape drive
properly cleaned can help you to avoid problems with your tape drive.
Media Grades
The following grades of media can be used with your 20/40GB 4MM Internal Tape
Drive:
v Tape containing Program Transmittal Fixes (PTF) - PTFs are tapes designed to be
written to only once and read from a few times. PTF tapes are not designed to be
used as a backup medium.
v Storage tapes - Storage tapes are designed to be used for backing up files that may
be reused numerous times and also for long-term storage.
Note: Your system supplier may only support the media they sell. If the
representative’s analysis indicates that your problem is caused by inferior media
usage, it is your (the customer’s) responsibility to replace the inferior media.
Tape Handling and Storage
Most tape is supplied in a sealed cartridge. It is provided this way so that the tape will
remain in a clean environment. Opening the cartridge allows dirt and airborne particles
to enter and then become a source of contamination. The cartridge should only be
opened by the tape drive and not an operator. The tape also is held under proper
tension inside the cartridge. If the cartridge is dropped, this tension will be relaxed.
Inserting a dropped cartridge into a tape drive can cause incorrect loading and result in
a jam. This will ruin the tape and can cause physical damage if the cartridge is not
removed properly.
When the tapes are stored, they must be replaced in their protective containers and
stored on their end. The storage area must be clean, dry, normal room temperature and
away from any magnetic fields.
Environmental Issues
Tape drives are designed to operate in a clean environment. Problem factors are dirt,
dust, fibers and airborne particles. Airborne particles are the most difficult to address.
When a tape is installed into the tape drive, the clearance between the heads and the
tape is measured in microns. Particles can damage the tape or the head if they come in
contact with either. Your service representative offers a tape drive filter enclosure for
some systems to solve this problem. The enclosure draws air in through a filter and
supplies the tape drive with clean air. Customers are responsible to provide a clean
operating environment for the tape drive and system.
Chapter 1. Overview 3
Tape Drive Cleaning
No matter how clean the environment, debris can build up on the heads of any tape
drive. Every time tape motion occurs, some of the media surface comes off on the
heads. Over time, this builds up and causes errors in reading and writing. Customers
are responsible to clean the tape drive in accordance with the cleaning information
provided with the tape drive.
Note: To identify the only media supported on this tape drive, refer to “Ordering Tape
Cartridges” on page 25.
Cleaning cartridges can be used a limited number of times. After a cleaning cartridge
has been used to its maximum number of times, the cartridge is considered expired.
When cartridges expire, they must be replaced. Never reuse an expired cleaning
cartridge. Doing so allows previously removed dirt to be reintroduced to the tape drive.
Place a mark on the cleaning cartridge after each use, to best determine when your
cleaning cartridge has expired.
SCSI Hardware Issues
Note: If you are installing the auto-docking version of this device on your system, this
section does not apply to your system. See your system documentation for
information about the auto-docking feature.
SCSI bus cables and terminators can affect tape drive performance. Use cables and
terminators that are designed specifically to keep the SCSI bus as free of noise as
possible. Generic cables or terminators can adversely affect the SCSI bus performance.
If your service representative’s analysis indicates a problem with inferior cables, it may
be necessary for the customer to replace them.
Microcode Updates
Your system supplier constantly works to provide the best possible tape drive products.
To make certain that the tape drives work their very best, your system supplier may
release changed microcode for the tape drives. When a microcode change is
developed, your system supplier makes the change available to you through its service
organization or by electronic delivery.
Microcode changes are available from service Web sites. For more information about
supporting Web sites, contact your local service representative.
Microcode can be installed by your service representative or your system administrator.
Summary
Your tape drive must be installed in the cleanest possible environment. Your 20/40GB
4MM Internal Tape Drive requires high-quality, data-grade tapes and cleaning on a
regular basis. Media must also be stored and handled properly. Improper use, storage,
or handling of tape drives or media may void your warranty or service agreement.
4 20/40GB 4MM Internal Tape Drive: Installation and Using Guide

Planning Your SCSI Device Layout
SCSI devices are attached in a daisy-chain configuration to a SCSI adapter inside your
system unit. SCSI devices can be installed inside your system unit or connected
externally. When you connect more than one SCSI device, it is important that you plan
the layout of your SCSI chain. Each device in the chain has a unique SCSI address
(also called a
SCSI ID
). A terminator is required at each end of the SCSI chain.
Determining Your SCSI Address
Before you install the 20/40GB 4MM Internal Tape Drive, you must set the SCSI
address on the drive. First, determine which SCSI addresses are available to use. Then
you choose an address and install jumpers on the drive to set the selected address.
The 20/40GB 4MM Internal Tape Drive supports addresses 6 through 0 and 8 through
15. You can use any available SCSI address as long as no two SCSI devices on the
same chain use the same address. Usually, no device can use address 7, which is
reserved for the SCSI adapter.
SCSI addresses are in sequential order from highest to lowest priority. Refer to Table 1
on page 9 for the priority associated with each address. All SCSI devices can use SCSI
addresses 6 through 0. If your system unit and adapter support the wide (16-data bit,
68-conductor cable) SCSI interface, you may see addresses in the range of 0 through
15.
To determine what SCSI adapters are in your system, type the following at the system
prompt:
v lsdev -C | grep scsi
Press Enter. All SCSI adapters in the system are displayed in the following format:
scsi0 Available 00-00-0S Standard SCSI I/O Controller
scsi1 Available 00-01 SCSI I/O Controller
To determine the SCSI address for the adapter you will attach to, type the following at
the system prompt:
v lsattr -El scsi0 | grep id
Where
scsi0
is the adapter that the tape drive is to be attached. Press Enter. The
SCSI ID is displayed in the following format:
id 7 Adapter card SCSI I True
To find an available SCSI address, do the following:
1. To identify the SCSI addresses used by all other devices, type:
lsdev -Cs scsi
Press Enter. A list of devices displays in the following format:
hdisk0 Available 00-00-0S-0,0 2.0GB SCSI Disk Drive
hdisk1 Available 00-02-01-2,0 4.5GB 16 Bit SCSI Disk Drive
hdisk2 Available 00-02-01-3,0 SCSI Disk Drive
rmt0 Available 00-02-01-4,0 SCSI 8mm Tape Drive
