Chapter 1. Overview
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 4.0GB, and 12.0GB 4mm
tape cartridges. The 20/40GB 4MM Internal Tape Drive can be used as a boot device.
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 20/40GB 4mm data cartridges
v Data rate of 3.0MB/second
v Capacity of 20GB
v Compression capability, which effectively doubles the native capacity of 20GB 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 SMIT to change the default.
Note: The factory default setting is
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
There are two different grades of media that could 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 which
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.
2 20/40GB 4MM Internal Tape Drive: Installation and Using Guide
Tape Drive Cleaning
No matter how clean the environment, debris may 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: Your system supplier may only support the use of their own cleaning cartridges.
Contact your system supplier for quality cleaning cartridges that are specifically
designed for the 20/40GB 4MM Internal Tape Drive.
Cleaning cartridges can be used a limited number of times. Once 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
SCSI bus cables and terminators may 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 may 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.
Summary
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.
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.
If a tape drive stops functioning due to a component failure during the tape drive
warranty or maintenance time, the service provider will replace the tape drive unit. The
service provider will replace any defective tape drive under the terms and conditions of
its warranty or service agreement. It is the service provider’s objective to work with you
to identify the cause of any tape drive problem and provide a solution.

Cleaning the Tape Drive
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, residue builds up and causes errors in reading and writing.
Customers are responsible for cleaning the tape drive in accordance with the cleaning
information provided with the tape drive.

Note: Refer to “Ordering Tape Cartridges” on page 23 to identify the only media
supported on this tape drive.
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.
When you have cleaned the tape drive, mark the usage on the cartridge in order to best
determine when your cleaning cartridge has expired.
SCSI Hardware Issues
SCSI bus cables and terminators may affect tape drive performance. The cables and
terminators supplied with your system are designed specifically to keep the SCSI bus
as free of noise as possible. Use of nonsupported cables or terminators may adversely
affect the SCSI bus performance. If service personnel analysis indicates a problem with
nonsupported cables, it may be necessary for the customer to replace them with the
appropriate supported cables. Contact your customer service representative if your
system’s cables or terminators need to be replaced.

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.
5
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 7 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
and press Enter. A list of devices appears 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
In the fourth position of the third column, locate all instances of the port that you
chose in step 1. (The list may contain multiple instances of a port. In the following
example, for port 2 (identified in step 1) there are three instances.) The addresses
of the other SCSI devices appear in the seventh position (highlighted in the
example.)

Handling Recommendations
Attention: Be sure to read “Handling Static-Sensitive Devices” on page vii before you
remove the 20/40GB 4MM Internal Tape Drive from its anti-static bag or any time you
handle it.
For optimum performance, always follow the recommendations listed below:
v Handle the drive carefully and by its external metal chassis. Keep your hands away
from the printed circuit boards, components, and printed circuit (flex) cables.
v If possible, work on a cushioned surface, and do not drop the tape drive onto the
work surface.
v If you move tape drive to an environment that is colder or warmer than its previous
environment, keep the drive in its package and allow the package to reach the
current room temperature. This prevents potential data loss or damage to the tape
drive. Allow one hour of acclimation for each 10 degrees C (18 degrees F) difference
between the ship or storage temperature and the room temperature.
Setting the SCSI Address
The 20/40GB 4MM Internal Tape Drive is shipped with jumpers packaged in a small
plastic bag. After you choose an available SCSI address, you can install the jumpers on
the tape drive to match the selected address. Refer to “Determining Your SCSI
Address” on page 6 if you need instructions for selecting the SCSI address.
To set a SCSI address, insert jumpers onto pin positions reserved on the jumper block
specifically for setting the address. To set a position to On, insert a jumper onto both
the top and bottom pins. To set a position to Off, either insert a jumper onto the top pin
only or remove the jumper from the jumper block.
Refer to the figure on page 10 and to Table 2 on page 10 as you go through the
following steps to set the SCSI address on your 20/40GB 4MM Internal Tape Drive:

Chapter 5. Using the Media
The 20/40GB 4MM Internal Tape Drive uses 4mm data cartridges for saving and
restoring system data. It is designed to use only DDS (Digital Data Storage) data
cartridges. The cartridges are identified by one of the following DDS symbols:
The 20/40GB 4MM Internal Tape Drive only reads and writes data to tape cartridges
that are DDS-2, 3, or 4 format.
Note: The 20/40GB 4MM Internal Tape Drive only supports DDS-2, 3, and 4 tape
cartridges. If any other cartridge is inserted in the drive, it will be ejected.
The 20/40GB 4MM Internal Tape Drive has been designed to operate with DDS media
that meet the following standards of the European Computer Manufacturers Association
(ECMA):
v ECMA-198 DDS-2 format
v ECMA-236 DDS-3 format
v ECMA-288 DDS-4 format
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.
Types of Tape Cartridges
The 20/40GB 4MM Internal Tape Drive is shipped with the following media cartridges.
Data Cartridge Use the 4mm data cartridge to save or restore programs or data.
Test Cartridge Use the specially labeled 4mm test cartridge to run the AIX system

Recommendations for Data Cartridge Usage
The following list describes recommended guidelines that will help to protect your data
and prolong the life of your tape cartridges and the 20/40GB 4MM Internal Tape Drive:
v Use only 4mm DDS-2, DDS-3, or DDS-4 cartridges. (DDS-4 media is recommended
whenever possible as it best optimizes overall drive advantages).
v Remove the tape cartridge from the drive when the drive is not in use.
v Back up and then discard any tape cartridge that repeatedly produces error
messages (the error information is in the System Error Log).
v On the data cartridge, do not open the door that covers the tape. The door protects
the tape from dirt, dust, and damage.
v Do not touch the tape. Any substance transferred to the tape by touching could
cause loss of data.
v To avoid problems with loading and unloading, use only one label on a cartridge.
Multiple or poorly placed labels can clog the drive load mechanism.
v Do not use poor-quality tape cartridges. They can cause excessive read or write
errors, and may damage the tape drive.
v Discard any tape cartridges that are dropped, as the impact may damage the tape’s
internal mechanism.
v Make sure the environment is kept clean and constant. Do not operate in a dusty
environment and always maintain a constant environment. A consistent storage and
operating environment reduces media exposure to climatic stress.
v The 20/40GB 4MM Internal Tape Drive does automatic cartridge recognition for both
write and read. The density settings, as shown with the AIX SMIT command, should
not be manually changed by the user. The tape drive controls the format of the data
written to the tape cartridge through automatic media recognition.
Attention: Use only the recommended cleaning cartridge to clean the tape drive. Use
of other than recommended cleaning cartridges can damage your drive and may void
the warranty.
v Printers and copiers can produce paper and toner dust. Locate the tape unit away
from these items. High traffic areas near hallways and doors can also produce
excess dust and dirt.
v All important information should be recorded on the tape label. Information, such as
the model and number of the system or tape drive, the date, the density, any error
statistics, and a log number should be included. The operating environment and
compression mode should also be noted.
Prolonging Head Life
The new technology in the 20/40GB 4MM Internal Tape Drive is read and write
compatible with DDS-2, DDS-3, and DDS-4 media. Due to media characteristics,
extended use of DDS-2 and DDS-3 tape cartridges may increase head wear on the
drive. An indication of this head wear is an increase in soft (recoverable) errors. Using a
quality DDS-4 tape reduces drive head wear and maximizes the overall advantages of
the 20/40GB 4MM Internal Tape Drive.
20 20/40GB 4MM Internal Tape Drive: Installation and Using Guide
Data Cartridge Erasure
Most bulk eraser devices do not have the capability to erase the 4mm data cartridge. To
properly erase a 4mm data cartridge with a bulk eraser device, the erasure coercivity
rating must be a minimum of 3900 Oersted.
Storage and Shipping Environments
Before using a tape cartridge, let it acclimate to the operating environment by placing
the cartridge in the operating environment for as long as it has been away from the
environment or for 24 hours, whichever is less. (To determine the appropriate operating
environment, see “Tape Drive Environment and Use” on page 2.)
Acclimation is necessary for any data cartridge exposed to a different humidity
environment or to temperature changes of 11°C (20°F) or more.
Retrieval of archived data should be performed on a tape unit that is clean and fully
operational. Try to make the recovery environment the same as the operating
environment. Allow tapes at least 24 hours to acclimate to environment of the tape unit.
The recommended environment for storage and shipment of 4mm data cartridges is
shown in Table 4.

Tape Cartridge Storage
Tape drives record data using densities similar to hard disk drives. Because most
computer systems are not located in a dust-free, climate-controlled environment, you
must exercise special care when dealing with tape cartridges and tape drives. They
need to be treated as a valuable asset used to protect your business data.
Use the following guidelines for storing your tape cartridges:
v Temperature and humidity should be kept constant at a level comfortable for you.
v Tape cartridges should always be stored in their protective cases. The storage case
helps prevent damage from dust and physical misuse. When the tape cartridges are
not in use or being stored, they should be in their storage cases and stood on edge
Chapter 5. Media 21
in a designated storage location. Do not stack cartridges on the flat side or stack
other items on top of the tape cartridges. Handle your tape cartridges with care to
reduce archival problems.
v Tape cartridge protective cases should be kept closed except when inserting or
removing a cartridge. Contamination can build up and be transferred to the tape
cartridge if the protective case is left open.
v Stored tapes should be exercised at least once every 12 months. Run the tape from
Beginning of Data (BOD) to End of Data (EOD) and back to BOD at normal
operating speeds. Tapes stored in a warmer environment should be exercised more
frequently.
v Sunlight can damage the tape and the cartridge shell. Store tape cartridges out of
the direct sunlight
Attention: Operation outside of the recommended environment can result in possible
loss of data or failure of the drive.
Operating in Harsh Environments
Do not use as an archival tape any tape that has been used outside of the operating
ranges specified in “Storage and Shipping Environments” on page 21 for an extended
period of time. The magnetic and physical strength of the tape will have deteriorated as
a result of its exposure to the environment. Do not store important data on such a tape;
transfer the data to a newer tape for reliable archiving.
Attention: Do not operate the 20/40GB 4MM Internal Tape Drive in a poor air-quality
environment. If your environment contains an excessive amount of particulates, contact
your service representative for more information.
Setting the Write-Protect Switch
The position of the write-protect switch on the 4mm tape cartridge determines when you
can write to the tape (see Figure 3 on page 23).
v When the switch is set to the right «1¬, data can be written to and read from the
tape.
v When the switch is set to the left «2¬, data can only be read.

Figure 3. Setting the Write-Protect Switch
Ordering Tape Cartridges
All tape cartridges are not alike. The tape composition and length, and the construction
of the cartridge itself can all affect the quality and capacity of the recording and the
performance of your tape drive. A poor quality tape cartridge may appear to work
adequately in your system, yet it can leave contamination in the tape path or impede
the speed of the recording.
The length and composition of the tape, and the size, shape, and construction of the
cartridge shell must all be considered when selecting the tape cartridge to be used with
your system. Data grade tape media is the only type of tape media that should be used
for backup and data processing. Saving money by using generic media for data
purposes will do little to save your business if your data is destroyed and your backup
tapes fail because of inferior media.
