Tape Drive Technology

Tape Drive Technology 1

The DLT-S4 tape drive incorporates state-of-the-art technologies that
contribute to the SDLT architecture. Some of these ideas are trademarked,
others are patented. The following subsections introduce the important
technologies that together, comprise the DLT-S4 tape drive system.

Tape Leader
Buckling Mechanism

The DLT-S4 tape drive system (see figure 1
Laser Guided Magnetic Recording (LGMR) technology. LGMR provides a
unique combination of the best optical and magnetic technologies, which
results in dramatically higher capacities by substantially increasing the number
of recording tracks on the data-bearing surface of the media.

Magneto Resistive Cluster (MRC) heads are a densely packed array of small
Magneto Resistive (MR) tape heads precisely positioned using advanced thin­film processing technology.

Improving on Partial Response Maximum Likelihood (PRML) technology
traditionally used in disk drives and communication systems, Quantum’s
advanced PRML channel technology, co-developed with Lucent Technologies,
brings new levels of performance and capacity to high-performance linear tape
products.

Advanced Metal Powder (AMP) media is a state-of-the-art media using
durable metal powder technology for recording high densities of data. The
back side of AMP media receives a specially formulated coating to accept the
optical servo tracks, which ensures that the entire data-bearing side of the
media is available for recording data and eliminates the need for pre­formatting.

The positive engagement tape leader buckling mechanism engages the media
leader on cartridge load and disengages it on cartridge unload. It uses a metal
pin attached to the tape drive leader to link with molded clips permanently
attached to the media leader inside the cartridge.

DLT-S4 Product Manual 5

Chapter 1 Product Information

Tape Drive Design

Tape Drive Design 1

The DLT-S4 tape drive is designed as a total system. The system includes
a complex interaction of a number of important components including
such items as the tape path, tape heads, media, cartridge, and host
interface.

For a detailed description of the integrated drive components, see the
DLT-S4 Product Specification (81-81279-xx).

Table 2 Tape Drive Components

Components Description

Base mechanical
assembly

Front-panel assembly
(bezel)

The base mechanical assembly houses the tape control mechanical, actuator,
reel motor, load mechanism, eject button, and front-panel indicators. It
positions the actuator servo head over the correct tape track. It implements the
functions required to buckle and unbuckle the media and control the media
motion. It is the mechanism responsible for engaging the media leader on
cartridge load and disengaging it on cartridge unload.

Auto load—The tape auto load is a soft load and seating mechanism that is
tolerant of forced media loading; a media sensor is triggered upon cartridge
insertion, and after the media reaches a hard stop point, the auto load sensor
engages pulling the cartridges the remaining distance onto the motor. On
media ejection, the assembly reverses the process and automatically ejects the
cartridge a fixed distance from the front of the tape drive

Base plate—Acts as the support platform for the other modules and for the
tape drive enclosure. It also includes the mounting holes (shock mounts) used
to install the tape drive into a server or tape library.

The front-panel assembly (bezel) performs these functions:

• Protects the front of the drive from physical damage

• Channels airflow through the system

• Aligns the cartridge when it is inserted into the system

• Provides label identifiers for the LEDs mounted on the front of the tape
drive

DLT-S4 Product Manual 6

Chapter 1 Product Information

Tape Drive Design

Components Description

• Enables cartridge ejection

• Reduces internal environmental contamination with a built-in dust door
(internal and tabletop configurations only)

Board assemblies The board assemblies provide the main control function for the system and the

interface from the system to the host computer, library, or autoloader. This
provides the Advanced Partial Response Maximum Likelihood (PRML) feature
of the Quantum SDLT technology.

There are three board assemblies:

• Pre-amplifier Board (PAB) — The PAB contains the preamplfier for the read
heads, and the write driver for the write heads.

• Motor Driver Board (MDB) — The MDB interfaces with the reel motor
drivers and hall sensors, actuator driver and sensors, sensor and motor
drives for the soft load, LEDs for front-panel indicators, and eject button
signals.

• Drive Control Board (DCB) — The DCB is the main control card for the DLT­S4 tape drive. It sends commands to the MDB to control and drive the tape
mechanism. The board interfaces with the PAB to send signals to the head
for reading and writing.

DLTSage is a suite of preventative maintenance diagnostic software tools
that enables users to more simply manage tape storage environments. It

1

enhances manageability by allowing you to manage, predict, and prevent
problems that can occur during a routine backup.

DLTSage software is a standard feature of the DLT-S4 tape drive and the
DLTtape S4 cartridge. To learn more about DLTSage, see:

•

www.dltsage.com

• DLTSage and DLTIce User’s Guide (81-81279-xx)

Table 3 DLTSage Features

Feature Description

Manage The software ensures that you use tape drives and media as efficiently as possible.

• It provides management protocols for acquiring information on DLT tape drives
and media anywhere on an enterprise network

• It helps you to understand and control how tape drives are used throughout the
system

• It allows you to develop a complete inventory of tape drives and media and the
usage statistics for each

Predict The software continuously monitors usage patterns and then interprets and

analyzes the operational information.

• You can ascertain which cartridges and which tape drives are nearing the end of
their useful lives

• You can predict when the tape drive needs cleaning

• You can use tape drive and cartridge usage statistics to implement predictive
maintenance parameters

Prevent The software allows you to see errors as they happen and correct them instantly.

• It alerts you to potential problems, enabling you to take corrective action

DLT-S4 Product Manual 9

Chapter 1 Product Information

Tape Drive Design

DLTIce Firmware 1 Quantum’s DLTIce firmware is an extension of the DLTSage architecture.

It acts as the compliance management function of DLTSage. The
firmware allows you to append data to an “iced” cartridge, but you
cannot rewrite, reformat, or erase the data.

This feature uses a Write Once, Read Many (WORM) functionality, which
provides you with the securely archived records that are needed to
achieve government regulatory compliance.

Quantum’s DLTIce firmware is a standard feature of the DLT-S4 tape
drive.

To learn more about DLTIce, see:

•

www.dltsage.com

• DLTSage and DLTIce User’s Guide (81-81279-xx)

Table 4 DLTIce Features

Feature Description

Security The tape drive’s firmware places an electronic signature key on each cartridge to

ensure that data written to the media cannot be rewritten, reformatted, or erased.

• The key is a unique identifier that cannot be altered

• The firmware allows you to append new data to the cartridge

• The cartridge initialization process assures that only unformatted cartridges will
be WORM enabled

Verification The verification is a two part process.

• The DLT-S4 tape drive provides best-of-class verification through its ECC
algorithms

• The firmware provides archive media verification and tamper verification with
time and date signatures

DLT-S4 Product Manual 10

Chapter 1 Product Information

Tape Drive Design

Feature Description

Identification The identification applies to both the data and the cartridges.

• The storage management software issues a time and date stamp, which enables
you to locate and authenticate specific records using ISV compliant storage
management software

• The cartridge used for DLTIce is a standard DLTtape S4 cartridge. Load the
firmware through DLTSage and use the special yellow labels provided by
Quantum to identify the WORM cartridges

Duplication The data stored on the DLTtape S4 cartridge can be downloaded to another storage

media through any ISV-compliant storage management software.

See “Icing” a Cartridge

on page 91 for instructions on how to create a WORM

cartridge.

DLTtape S4 Cartridge 1 A cartridge is a significant component of any tape drive system. The

DLT-S4 tape drive writes to DLTtape S4 cartridges.

• Color and Pattern — The DLTtape S4 cartridge is and has a
distinctive pattern, in addition to the DLTtape logo, molded in the
plastic.

• Geometry — The cartridge’s geometry is similar to previous DLTtape
cartridges to simplify integration with existing tape library designs,
but has a keying feature to ensure it cannot be loaded into previous
generations of tape drives where writing to the media is
incompatible.

• Debris Resistance — The cartridge is made of wear-resistant
materials to reduce the potential for debris generation and increase
the life of the cartridge.

For more information on cartridges, see appendix A

on page 75.

TapeAlert

TapeAlert 1

DLT-S4 tape drives are delivered with TapeAlert features built in. The
tape drive firmware constantly monitors the device’s hardware and
media, checking for errors and potential difficulties. It flags any problems
identified on the

After a backup, the TapeAlert-compatible backup application
automatically reads the device’s TapeAlert
check for any problems. If an error is flagged, your backup software
displays a warning message on your screen, and adds the TapeAlert
messages to its logs. These messages are standard across all applications
that support TapeAlert, and give an explanation of the problem and
suggested resolution. For example, if you were attempting to back up to
an expired cartridge, you would see the following message:

WARNING: The data cartridge has reached the end of its calculated useful life.
Copy any data you need to another cartridge.

Discard the old cartridge.

Safety Precautions 2 For your safety, follow all safety procedures described here and in other

sections of the document.

1 Power off the system before installing or removing the tape drive to

prevent the possibility of electrical shock or damage to the tape drive.

2 Unplug the unit that contains—or is to contain—the tape drive from

AC power to provide an added measure of safety.

3 Read, understand, and observe all label warnings.

The POS uses a Class I laser product. This laser product complies
with 29 CFR 1200 and 29 CFR 1910 as applicable on the date of
manufacture.

Warning: If you open the tape drive chassis, you may become

exposed to invisible laser emission which could be
harmful if you are directly exposed to the beam.

Handling Instructions 2 Damage to the DLT-S4 tape drive system can occur as the result of

careless handling, vibration, shock, or electrostatic discharge (ESD). For
more details on ESD, see Electrostatic Discharge Protection

on page 20.

Caution: Never power off the tape drive or the host while the tape

drive contains a cartridge. Failure to remove a cartridge
may result in cartridge or tape drive damage.

Follow these guidelines to avoid damage to the tape drive.

Do or
Do Not Handling and Using Guidelines

Do • Always handle the tape drive carefully and gently— a

drop of ¼ inch onto a bench or desktop can damage a
tape drive

• Always place the tape drive on a flat, stable surface

• Hold the internal tape drive only by its sides

Caution: Never hold the tape drive by inserting your

fingers into the receiver area on the front of the

• Expose the tape drive to dusty, humid, or smoke-filled
areas

• Place foreign objects inside the tape drive’s receiver area

Do or
Do Not Storage Guidelines

Do Not • Stack objects on the tape drive

• Expose the tape drive to dusty, humid, or smoke-filled
areas

Electrostatic Discharge Protection

Several electrical components of the DLT-S4 tape drive system are
sensitive to static electricity and electrostatic discharge (ESD). Even a

2

static buildup or discharge that is too slight to feel can be sufficient to
destroy or degrade a component’s operation.

To minimize the possibility of ESD-related damage to the system, the
tape drive’s manufacturer strongly recommends using both a
workstation antistatic mat and an ESD wrist strap. If the devices are
correctly installed and properly used, they reduce the buildup of static
electricity that might harm the system.

DLT-S4 Product Manual 20

Chapter 2 Tape Drive Installation

Safety, Handling, and ESD Protection

Follow these guidelines to avoid damage to the tape drive.

Do or

Do Not ESD Guidelines

Do Always use proper electrostatic discharge (ESD) protection.

• Use a properly fitted wrist strap or other suitable ESD
protection

• Observe proper ESD grounding techniques

• Keep the internal tape drive in its antistatic bag until
ready to install

• Place the tape drive in the antistatic bag before placing it
in a shipping container

• Hold the tape drive only by its sides

• Place the tape drive on a properly grounded antistatic
work surface pad while it is out of its protective
antistatic bag

Do Not • Pack other materials with the tape drive in its antistatic

bag

• Use the bag as a substitute for the work surface antistatic
pad

The outside surface of the bag may not have the same
antistatic properties as the inside surface. It could
actually increase the possibility of ESD problems.

• Remove covers to use any test equipment to check
components on the PCBAs

There are no user-serviceable components on the tape
drive.

Chapter 2 Tape Drive Installation

Internal SCSI Tape Drive Configuration

You can configure internal tape drives for SCSI ID addresses that range
from 0 to 15 in one of two ways:

• Place a jumper on the 12-pin SCSI ID block located on the rear of the
tape drive (see table 7

)

• Set the SCSI ID through firmware in a library setting

Table 7 SCSI ID Address
Selections

Note:

The firmware default is SCSI ID 5 and assumes no jumpers
are installed on the jumper block. If you omit all jumpers
from the SCSI ID connector, the tape drive will use the
default setting of 5.

The default setting for the tape drive is 5; the host adapter setting is
typically SCSI ID 7. If you choose to omit all jumpers from the SCSI ID
block, the tape drive will use the default setting of 5.

Power-On Self-Test 3

The DLT-S4 tape drive system performs a self-diagnostic test, called a
Power-On Self-Test (POST) each time you turn on the tape drive (see

table 14

POST completes in approximately 10 seconds. While POST is running,
the tape drive system responds BUSY to SCSI commands, but will
respond to various SCSI messages.

During this time, if a host tries to negotiate:

• Synchronous transfer — the tape drive system negotiates to

• Wide transfer — the tape drive system negotiates to Narrow

It may take longer than the duration of POST for the tape drive to become
ready.

Firmware Update via the SCSI Bus

Firmware Update via the SCSI Bus 3

When you need to update the firmware in the tape drive, you can do it
either of two ways:

• By directly using the SCSI bus

• By creating a firmware image cartridge (CUP/FUP) to use in either a
manual firmware update or in a library setting

DLTSage provides the tool that allows you to update the tape drive’s
firmware using the SCSI bus, or to create a CUP/FUP cartridge for an
DLT-S4 tape drive. See

The following subsections briefly describe both methods of updating the
tape drive firmware.

www.quantum.com for information on DLTSage.

Updating the Firmware Using the SCSI Bus

Quantum provides upgrades for product software and firmware that
may be newly developed. These updates are available on the Quantum

3

Web site.

3

you find the update you need.

4 Download the DLTSage package and refer to that tool’s built-in on-

line help for detailed instructions on how to create the cartridge.

Using the CUP/FUP Cartridge

Follow these steps to use a CUP/FUP cartridge:

3

1 Verify that the tape drive is turned on (power is applied), and the

middle LED on the front panel of the tape drive is on, but not
flashing.

2 Verify that the tape drive’s cartridge opening is empty.

In other words, if any other cartridge is in the tape drive, unload and
eject it before proceeding.

3 Press and hold the Eject button for six seconds; after six seconds, the

left LED begins to flash.

4 Release the Eject button, then quickly press and release the Eject

button again.

At this point, the left and middle LEDs start flashing synchronously
in a regular, rhythmic pattern. The tape drive is now in Firmware
Upgrade mode.

You now have a “window” of one minute to insert the CUP/FUP
cartridge. If you do not insert a CUP/FUP cartridge and the one
minute time window expires:

• Both LEDs stop flashing, although the middle LED remains on

(steadily illuminated)

• The tape drive is now out of Firmware Upgrade mode and can be

used in a normal manner (once you insert a cartridge)

To put the tape drive back in Firmware Upgrade mode, repeat steps

2

, 3, and 4.

5 Insert the CUP/FUP cartridge.

After you insert the CUP/FUP cartridge, the left and middle LEDs
change their pattern and start flashing in an alternating pattern. The
tape drive is now performing the firmware upgrade.

DLT-S4 Product Manual 56

Chapter 3 Tape Drive Use

Firmware Update via the SCSI Bus

Note: The firmware upgrade fails the update process if the

firmware personalities do not match. The history log
records this information, as well as the reason for the
failure.

Wait several minutes for the update process to complete.

6

The left and middle LEDs flash the entire time that firmware is being
updated.

When the update is complete, the tape drive resets itself and goes
through POST. The tape drive rewinds the CUP/FUP cartridge, then
unloads and ejects it. SCSI status indicates that firmware has been
updated (06h, 3F, 01).

Note: If the tape drive is mounted in a tape automation library,

the CUP/FUP cartridge rewinds to BOT and unbuckles in
preparation for unloading, but does not automatically
eject. Use the applicable library command to eject the
cartridge.

DLT-S4 Product Manual 57

Chapter 3 Tape Drive Use

Firmware Update via the Library Tape Drive Interface

Firmware Update via the Library Tape Drive Interface 3

The DLT-S4 library tape drive interface enables you to update the
firmware with a new version, or image via media update.

Follow these steps.

1 Ensure that the tape drive contains no cartridge.
2 Send the CODE UPDATE REQUEST command.
3 Send the library ATTENTION command, then check the Tape Motion

Status field of the returned General Status Packet to verify the tape
drive is in the Ready for Code Update (0x09) state.

4 Load the cartridge containing the new firmware into the tape drive.
5 Send the library ATTENTION command, then check the Tape Motion

Status field of the returned General Status Packet to verify the
cartridge is loading (0x07).

Note: It takes about a minute to get into the Cup in Progress

state.

6 Send the library ATTENTION command, then check the Tape Motion

Status field of the returned General Status Packet to verify the
cartridge is in the Cup in Progress (0x0A) state.

7 Send the library ATTENTION command, then check the Policy

Firmware Revision field to verify that the update completed
successfully.

8 Unload the cartridge and remove it from the tape drive.

Caution: During the firmware update, when reprogramming

the new image into the flash EEPROMs is actually in
progress, a power failure (but not bus RESET) or

power cycling the unit causes the controller module
to be unusable. When doing a firmware update, take

reasonable precautions to prevent a power failure.

Cleaning the Tape Mechanism

Cleaning the Tape Mechanism 3

This section discusses the DLT-S4 tape drive cleaning cartridge,
maintenance considerations, and important compatibility issues.

Note: Do not clean the tape drive unless the tape drive specifically

indicates that cleaning is necessary. When your backup
software indicates that you need to clean the tape drive, or the
yellow LED on the tape drive comes on, use the cleaning
cartridge to clean the unit.

Occasional Cleaning of Tape Heads

Cleaning the Tape Drive 3 To clean the tape drive’s tape heads, follow these steps:

Quantum tape drives occasionally require preventive cleaning. The
amount of ambient pollution and particulates in the environment, to a

3

large degree, dictates the cleaning frequency.

Clean the tape drive only when cleaning is necessary. The DLT-S4 tape drive
uses a built-in media cleaning algorithm in conjunction with a cleaning
cartridge. Your backup software or the right LED located on the front
bezel of the tape drive notify you if you need to clean the tape drive. For
the location of this LED and other front bezel LEDs, see figure 22

The cleaning cartridge is packaged in a plastic case, and is white in color.

Caution: Do not clean the tape heads unless the right LED is

illuminated. Use ONLY the SDLTtape CleaningTape.
Other cleaning cartridges, such as CleaningTape III or
DLT VS CleaningTape, are incompatible with the DLT-S4
tape drive heads.

Note: To use the cleaning cartridge in an autoloader or library tape

drive, see the autoloader or library owner’s documentation.

.

1 Insert a cleaning cartridge (the brand name to look for is SDLTtape

CleaningTape) into the tape drive.

DLT-S4 Product Manual 59

TM

Chapter 3 Tape Drive Use

Cleaning the Tape Mechanism

The green middle LED flashes and the cleaning cycle begins
automatically. Based upon previous cleaning cartridge usage, the
cleaning operation may last up to 10 minutes.

When the cleaning cycle completes, the tape drive automatically
ejects the cleaning cartridge; turns off the right LED; and steadily
illuminates the middle LED.

2 Remove the cleaning cartridge, place it back in its plastic case, and

mark the label after each cleaning.

Note: On the last cleaning, the tape drive does not eject the

cleaning cartridge. Use the Eject button on the front of the
tape drive to eject the expired cleaning cartridge and
dispose of it.

Cleaning Cartridge Life Expectancy

Cleaning Cartridge Compatibility

Each cleaning cartridge is good for 20 uses. Use one of the labels that is
supplied with the cleaning cartridge to track the number of uses and

The cartridge rewinds to BOT and unbuckles in
preparation for unloading, but does not
automatically eject.

Optimizing the Tape Drive Performance 3

Many factors contribute to tape drive performance. Host system
considerations include processor speed, block size, SCSI adapter
performance, host bus configurations, and software.

If you are concerned about the performance of the tape drive, check the
following:

• Ensure that the tape drive is properly defined for the host system.

If the tape drive is not defined within the system, the SCSI adapter
does not interact well with the tape drive.

• Ensure that the controller card and the SCSI bus are operating in
LVD.

• Check the host block size.

The DLT-S4 tape drive supports block sizes up to 16 MB. In general,
the larger the block size, the better the throughput. Many older
software applications default to a 512-byte block size, which results
in poor performance.

• Ensure that you are using a cartridge that is compatible with the tape
drive.

Cartridge Handling Guidelines

Cartridge Handling Guidelines 1

DLTtape S4 cartridges are engineered to be reliable, robust, and durable.
By following general handling procedures, conducting careful
inspections of cartridges on a regular, ongoing basis, and being certain to
store cartridges within their environmental limits, you will greatly reduce
any chance that you will experience problems with the cartridges or
cause damage to the tape drive system. Respect the media as much as
you do your data.

The ambient operating

Temperature 10

Relative Humidity 20% to 80% (non-condensing)

Note: If storage or transportation of a cartridge has exposed it to

conditions outside the ambient values shown in the preceding
table, “condition” the cartridge to its operating environment
for a 24-hour period.

environment for the cartridge is:

°C to 40 °C (50 °F to 104 °F)

DLT-S4 Product Manual 79

Appendix A Cartridges

Cartridge Handling Guidelines

Follow these guidelines to avoid damage to the cartridges.

Do or
Do Not Handling and Using Guidelines

Do • Orient the cases so that the grooves in the cases

interlock—while carrying cartridges in their cases

This prevents the cases from slipping apart and falling.

• Protect cartridges from shock, vibration, moisture,
direct sunlight, dust, smoke, and magnetic fields

Note: Devices that may produce magnetic fields, such as

computer monitors, motors, or video equipment
can alter or erase data on the media.

• Use only the slide-in label provided with each cartridge
and slide it into the label slot on the cartridge

Never apply adhesive labels or “sticky” notes on the top,
side, or bottom of tape cartridges.

DLT-S4 Product Manual 80

Appendix A Cartridges

Cartridge Handling Guidelines

Do or
Do Not Handling and Using Guidelines

Do • Ensure that you place the unused cartridge labels in the

protective box so that you do not inadvertently pick
them up along with the cartridge during subsequent
usage

Static electricity may cause a label to cling to the cartridge.
A label that is accidentally inserted into the tape drive
along with a cartridge can prevent the hub reel and tape
drive gear from meshing.

Do Not • Use graphite pencils, water-soluble felt pens, or other

debris-producing writing instruments on the labels

Replace labels instead of erasing them.

• Carry cartridges loosely in a box or any other container

Allowing cartridges to jostle together exposes them to
unnecessary physical shock.

• Unnecessarily open the cartridge door

This may expose the media to contamination or physical
damage

• Touch or allow direct contact with the media or media
leader

Dust or natural skin oils can contaminate the cartridge and
impact media performance.

• Drop the cartridge

Note: A dropped cartridge may have dislodged,

loosened, or damaged internal components. If you
drop a cartridge, give it a thorough visual
inspection (see Inspecting a Cartridge

for

complete instructions).

DLT-S4 Product Manual 81

Appendix A Cartridges

Inspecting a Cartridge

Follow these guidelines to avoid damage to the cartridges.

Do or
Do Not Storage Guidelines

Do • Keep each cartridge in its protective plastic case while it

is not in the tape drive

• Ensure that you stand each cartridge vertically—while
placing cartridges in archival storage

• Observe the proper environmental conditions for
storing cartridges

Do Not • Stack more than five cartridges on top of each other

Inspecting a Cartridge 1

Improper cartridge handling is the primary reason for tape drive
problems. To avoid losing data or damaging the tape drive, inspect the
cartridges:

• Before loading a new cartridge in the tape drive

• After dropping a cartridge or subjecting it to physical shock

• When the tape drive becomes inoperable after loading a cartridge

DLT-S4 Product Manual 82

Appendix A Cartridges

Inspecting a Cartridge

• When you receive a shipment of cartridges that show any sign of
shipping damage

Follow these steps to inspect a tape cartridge.

1 Gently shake the cartridge and listen for loose pieces.
2 Remove the cartridge from its protective plastic case.
3 Check for loose debris attached to the shell, and for other

contamination (oily, slimy, or sticky substances) that may have built
up on the surface of the shell.

4 Check the cartridge for any obvious cracks or other physical damage

to the shell. Rotate the cartridge in your hands, looking for broken or
missing parts.

5 Rotate the cartridge to view the bottom (see figure 26).

The media access door is on the top edge and the write protect tabs
are on the bottom edge. Confirm that the spring-loaded hub on the
bottom of the cartridge is centered. Press the hub to ensure that the
spring is functioning properly and that the hub returns to its normal
position.
