Overview
Introduction to the DAT AutoLoader
The Compaq 20/40 Gigabyte (GB) DAT 8-Cassette AutoLoader combines a
changer mechanism with a DDS-4 cassette drive mechanism. The DAT
AutoLoader houses up to eight DDS cassettes in a removable magazine, which
enables you to back up weeks and months of data automatically. High-speed
file retrieval and cassette swapping typically allow access to any file in an
average of 95 seconds. The DAT AutoLoader supports both sequential and
random access modes, with minimum interruption time between cassettes.

Features
The Compaq 20/40 GB DAT 8-Cassette AutoLoader offers the following
features:
I
I
Any DDS-1, DDS-DC, DDS-2 DDS-3 or DDS-4 cassette can be read or
written to, whether data compression is switched on or off.
The drive is capable of additional sophisticated techniques of
error-correction for dealing with cassettes, which are not up to
specification.
I
I
I
When using DDS-4 media, the drive reads and writes the DDS-4 format
with a much higher capacity.
An improved internal cleaning sweeper reduces the frequency of
cleaning the heads by a factor of eight.
The TapeAlert feature allows software and operating systems to warn
users of conditions which may occur, such as a cassette nearing the end
of its useful life, and to recommend actions that the user can take to
recover from the situation.

Overview 1-3
The SCSI Interface
The Compaq 20/40 GB DAT 8-Cassette AutoLoader uses SCSI-2 as the
interface to connect the host system.
IMPORTANT: In the information that follows, the term SCSI implies SCSI-2.
The SCSI implementation provides the DAT AutoLoader with a standard set
of features and functions. These include the following:
I
I
I
I
LVD Wide SCSI connection
Synchronous data transfers
Asynchronous data transfers
Implementation of all mandatory and most optional commands of the
Sequential Access command set
I
Full implementation of mandatory Medium Changer commands
Controller Requirements
Compaq recommends equipping the computer with an LVD 32-bit Fast
SCSI-2 Controller or higher. Any of these controllers fully support the
Compaq 20/40 GB DAT 8 Cassette AutoLoader.
IMPORTANT: All SCSI devices on the same bus must either be internal (within the
computer) or in an external storage device, but not both. The exception is a CD-ROM
drive, which may be internal when other devices are external or vice versa.
Reliability of Backup Devices
The reliability of any backup device is directly related to its duty cycle (the
number of hours per day that the device is in use). For example, if a tape drive
designed for 24-GB backups is being used to back up a 100-GB computer, the
result on that drive will be a need for accelerated preventive maintenance
(especially head cleaning), premature aging, and reliability problems. See
Chapter 5 for more information on cleaning requirements.

1-4 Compaq DAT AutoLoader Reference Guide
Projected Duty Cycle
The projected duty cycle of the Compaq 20/40 GB DAT 8-Cassette
AutoLoader is an important consideration in determining the amount of time
required for backup of a given system, as well as how often it is necessary to
clean the tape drive’s read/write heads.
For example, a nightly, unattended complete 18-GB backup is well within the
capacity of one 20/40 GB DAT drive. However, at a backup rate of
approximately 8GB/hour, that tape drive is in operation for approximately 2
1/4 hours every night of the week. With this amount of usage, the tape drive’s
read/write heads should be cleaned every 4 to 6 weeks. If the drive heads are
not cleaned soft errors and overall backup time increases and eventually
causes the drive to fail.
Capacity
The best method for building hardware reliability into a backup strategy is to
ensure that the backup hardware is matched to the computers. Table 1-1 relates
various computers with the appropriate tape drives. If you need special, partial
backups in addition to the routine backups, select the next larger drive size.

Data Compression
The Compaq 20/40 GB DAT 8-Cassette AutoLoader ships from the factory
with data compression enabled for writing. The drive is equipped with onboard
DDS-DC hardware, using the Data Compression Lempel Ziv (DCLZ)
algorithm. In this mode, data is always compressed when writing to the
cassette, but the drive is capable of reading both compressed and
uncompressed cassettes.

Overview 1-5
The DAT AutoLoader uses jumper pins and/or dip switches for settings. Some
hardware settings may be overridden by way of software. Consult your backup
application software documentation for the data compression enabling and
disabling procedure.
For information on jumper pin settings for data compression, see “Configuring
the AutoLoader” in Chapter 2.
Cassette Formats
The Compaq 20/40 GB DAT 8-Cassette AutoLoader supports
industry-standard Digital Data Storage (DDS), Digital Data Storage Data
Compression (DDS-DC), Digital Data Storage-2 (DDS-2), Digital Data
Storage-3 (DDS-3), and Digital Data Storage-4 (DDS-4) formats.
IMPORTANT: For product reliability Compaq recommends using only cassettes
purchased from vendors that have been approved by Compaq (See Table 1-2 for list of
approved cassettes).
These formats were introduced by the DDS Manufacturers’ Group and are
approved by the American National Standards Institute (ANSI) and the
European Computer Manufacturers’ Association (ECMA). The DDS-DC
format is a superset of the DDS format, ensuring backward compatibility with
uncompressed cassettes.
To use the full potential of a DDS-format drive, you should use matching
cassettes, that is, DDS-4 cassettes for DDS-4 drives. This allows the drives to
store the maximum amount of data on a cassette. Refer to Table 1-2 for a list
of Compaq approved cassettes.

DDS Logo Media
To identify computer-grade DDS media easily, look for the DDS logos (See
Figure 1-2), including ! DDS-1, " DDS-2, # DDS-3, and $DDS-4. These
indicate that the media meets the DDS specifications laid down by the ECMA,
ISO/IEC and ANSI standards.

Figure 1-2. DDS Logo Media
The Media Recognition System (MRS) enables drives to identify DDS-grade
media. DDS MRS cassettes have a series of stripes on the transparent leader at
the beginning of the cassette. The drive can be configured to treat non-MRS
cassettes as write-protected. In other words, the drive is only allowed to read
non-MRS cassettes, not write to them.

Overview 1-7
Write-Protecting a Cassette
IMPORTANT: The cassette log, which contains a history of usage of the cassette, is
updated during the unload procedure. If the cassette is write-protected, the cassette log
will not be updated and will be inaccurate.
Cassettes can be write-protected by ! sliding the tab on the rear of the cassette
to the left so that the hole is open (See Figure 1-3). In this state, data can be
read from the cassette but not written to it. To remove write-protection, "
slide the tab to the right so that the hole is closed.

(– = Write-protection ON, — = Write-protection OFF)
Life Expectancy of Cassettes
All DDS-certified media are designed to withstand at least 2000 passes. Under
optimum environmental conditions (50% relative humidity, 22°C), this is
equivalent to about 100 to150 backup operations. The life expectancy takes
into account that an area of a cassette may have several passes during a
backup, either because streaming (the optimum performance rate where data is
sent to the drive at approximately the same speed as it is written to the cassette
media) cannot be maintained, or because the backup software package
repeatedly accesses certain areas of a cassette.
Certain extreme (worst case) conditions reduce the recommended maximum
number of backup operations. These conditions are as follows:
I
Environmental conditions — Sustained use at the low end of the
humidity specification reduces the cassette life.
Download from Www.Somanuals.com. All Manuals Search And Download.
1-8 Compaq DAT AutoLoader Reference Guide
I
Computer performance — The lower the performance of the computer,
the more likely that streaming cannot be maintained and that an
increase in the number of passes over given areas of a cassette
will occur.
I
Backup Software — The backup software may frequently access certain
areas of a cassette, or there may be a high system overhead that can
cause streaming to stop. Both of these factors increase the number of
cassette passes in a given area.
Because these parameters vary from system to system, it is difficult to give a
definitive statement of the number of backup operations achievable using a
particular cassette.
As a guideline, Compaq recommends using a cassette for approximately 75
backup operations in worst-case conditions such as those listed above.

I
Disk = 0
Tape = 2
CD-ROM = 5
To determine the SCSI ID of the new tape drive (if not known):
1. Run System Configuration and look under “Review or Modify
Hardware Settings,” then “View and Edit Details.” The values reported
for controller number, target ID, LUN, and bus number are used during
mkdev tape.
2. Boot the computer to single user mode and run the mkdev tape command.
Download from Www.Somanuals.com. All Manuals Search And Download.
3-6 Compaq DAT AutoLoader Reference Guide
3. Remove the default tape device from controller 0, ID 2.
4. Add the new tape drive to the configuration.
5. Relink the kernel and reboot the computer to multi-user mode.
6. Run the hwconfig command to ensure the new tape configuration is
correct. The information appears in a line such as:
%tape - - - type= S ha=0 id=2 lun=0 ht= ...
In the above example, “id=2” indicates that the SCSI ID is 2.
See the section “Setting the SCSI ID,” in Chapter 2 for more information on
setting the SCSI ID.
IMPORTANT: SCO OpenServer’s install kernel only communicates with the first SCSI
controller in the system. Remove the generic tape at ID2, then add the correct tape driver
using correct ID, bus, and LUN values.
SCO UnixWare
The drivers required to support Compaq SCSI tape drives under SCO UNIX
are the SCO SCSI tape (stp) driver and an appropriate SCSI controller driver.

Introduction to Magazines and Cassettes
When purchasing DDS cassettes:
I
Always use cassettes labeled “DDS Media Recognition System” in the
drive. To use the full potential of the drive, make sure that they are
DDS-4 cassettes.
I
Never use DAT cassettes because the media is not certified and they can
have a different specification that can cause them to jam in the
mechanism (see Chapter 1 for cassette specifications).

4-2 Compaq DAT AutoLoader Reference Guide
Labeling Cassettes and the Magazine
Each cassette and the magazine should be labeled prior to use. To label a
cassette follow the manufacturer’s instruction included with each cassette. To
label the magazine, place the label on 1 space provided (see Figure 4-1).
Figure 4-1. Magazine identification
To prevent jams:
I
Insert cassettes all the way into the magazine.
I
Ensure the label corners are affixed firmly on the cassettes and
magazine –.
I
I
Only paste labels to the surface and make sure there are no curled edges.
Never paste labels on top of other labels.
IMPORTANT: Cassettes should be stored in their magazines so that they are kept
together and in the correct order when multi-volumes are backed up.
Loading the Magazine with Cassettes
The magazine holds eight cassettes. There are only three allowable magazine
configurations:

4-6 Compaq DAT AutoLoader Reference Guide
3. For an eight-cassette configuration, insert a cassette in position 8.
CAUTION: The cassettes must be loaded in the order they were originally
placed during backup.
Loading the Magazine into the
AutoLoader
Insert the magazine into the front opening on the AutoLoader in the direction
of the arrow. The AutoLoader pulls the magazine in the rest of the way.
Figure 4-8. Loading the magazine into the DAT AutoLoader
The AutoLoader does a rotation check of the cassettes. If there is an incorrect
cassette configuration the AutoLoader ejects the magazine. See “Loading the
Magazine with Cassettes” for the correct configurations.
Removing the Cassettes from
the Magazine
NOTE: Compaq recommends storing the magazine with the cassettes loaded to ensure
they are in the correct order.
1. Hold down the magazine stopper – in the direction of the arrow while
removing cassettes.
Download from Www.Somanuals.com. All Manuals Search And Download.
Operation 4-7
Figure 4-9. Slide stopper
2. To remove cassettes in positions 1 through 5 use the access slots on the
bottom of the magazine to slide the cassettes out the front of the
magazine.
3. Turn the magazine opening slots up. Gently tap the unit until the
cassettes in positions 6 and 7 drop to the bottom slots.
4. Repeat steps 1 and 2.
5. Press the magazine stopper down to pull the cassette from position 8.
Ejecting the Magazine
To eject a cassette magazine from the DAT AutoLoader, press the Eject
button or issue an UNLOAD command from the host. The following sequence
of events occurs:
1. The tape is rewound to BOP (Beginning of Partition).
2. If the tape is write-enabled, the copy of the tape log held in RAM is
written back to the tape.
3. The tape is then rewound to BOM (Beginning of Media) and
unthreaded.
4. The AutoLoader replaces the cassettes in the magazine in the correct
order.
5. The magazine is ejected.
Download from Www.Somanuals.com. All Manuals Search And Download.
4-8 Compaq DAT AutoLoader Reference Guide
If the host sends an UNLOAD command (LOAD/UNLOAD with the LOAD
bit set to 0), the same procedure is completed, but the magazine is not ejected
at the end.
If you press the Eject button during the 30 seconds when the DAT
AutoLoader checks magazine positions following insertion of a magazine, the
magazine is ejected immediately, even if Medium Removal Prevention is in
force.
If the host has previously sent a PREVENT MEDIA REMOVAL command,
the unloading action is different in two ways:
I
The Eject button is disabled and has no effect. It does not initiate an
unload sequence.
I
An UNLOAD command puts the drive into a semi-loaded state. It takes
the drive offline and unthreads the tape, but does not eject it.
The effects of PREVENT MEDIA REMOVAL continue until an ENABLE
MEDIA REMOVAL command is received, or the drive is reset.
Forcing Cassette Ejection
CAUTION: You can lose data if you force ejection of a tape. The tape may also
end up invalidly formatted because EOD (End of Data) may not have been
written. Force ejection only as a last resort to recover a cassette. Never use it as
a quick way of ejecting a cassette.
If you press the Eject button when the drive is busy, it may be a long time
before the drive responds to the request, because it is finishing the task it is
performing first. This method ensures that the task is terminated in a
controlled manner, and no data is lost.
However, if you need to unload a cassette urgently, even at the risk of losing
data, you must force ejection as follows:
1. Hold the Eject button down for at least 5 seconds. The LCD displays
“Force Eject.”
2. The DAT AutoLoader waits 35 seconds to give the normal ejection
procedure a chance to occur.
3. Once this time has elapsed, if there is a tape loaded in the drive, it is
immediately unthreaded and the cassette is ejected, regardless of what
operation the drive was performing. The cassette is then returned to its
position in the magazine, and the drive is reset as though the power has
been cycled.
Download from Www.Somanuals.com. All Manuals Search And Download.
Operation 4-9
Because the forced ejection may interrupt any operation, it is possible
that the drive will not write EOD (End of Data) before the cassette is
ejected. This will cause loss of data, and result in a cassette with an
invalid format. However, it should still be possible to read such a
cassette up to the point where the ejection interrupted the writing.
4. If no cassette is loaded in the drive, the DAT AutoLoader assumes that
you want to eject the magazine. Following the 35 seconds, it does eject
the magazine. The DAT AutoLoader is then reset as though power had
been cycled.
IMPORTANT: Forced ejection overrides any SCSI PREVENT MEDIA REMOVAL that may be
in effect, and can abort any SCSI operations in which the DAT AutoLoader is engaged.
Modes of Operation
The DAT AutoLoader can operate in either Stacker or Random mode.
Stacker Mode
In Stacker mode (also known as sequential mode), a cassette can be selected
using the Select and Enter buttons on the front panel. When a cassette is
ejected from the embedded drive after a host UNLOAD command, the DAT
AutoLoader automatically moves the next available cassette from the
magazine into the drive. In this mode the DAT AutoLoader does not depend
on the host computer to send SCSI MEDIUM CHANGER commands to move
cassettes to and from the magazine.
Random Mode
The AutoLoader enters this mode when it receives a SCSI MOVE MEDIUM
command. The Select button is disabled. The Eject button or SCSI UNLOAD
command will cause the AutoLoader to exit this mode.

Cleaning
Reliable backup of your system is the product of at least four components:
I
I
I
I
A reliable tape drive
Quality tape cassettes
Regular backup schedule with backup media stored offsite
Routine tape drive maintenance
The Compaq 20/40 GB DAT 8-Cassette AutoLoader is designed to operate
reliably under worst case conditions; however, it requires simple routine
maintenance to operate efficiently. Regular cleaning is the most essential step
in properly maintaining a tape drive and preventing errors.
For more information about cleaning Compaq tape drives, refer to the Compaq
“Whitepapers.”
Importance of Routine Cleaning
IMPORTANT: Regular cleaning is vital to trouble-free operation of any tape device.
Failure to follow recommended cleaning procedures could result in serious damage to
your tape drive. Compaq recommends a routine cleaning every 100 hours of use.
Routine cleaning of a tape drive minimizes buildup on the read/write heads so
that fewer cleaning cycles are required to keep the tape drive in good working
order. When a tape drive is cleaned according to a regular schedule, one
cleaning cycle typically removes accumulated dirt and particle deposits. If the

drive is not cleaned regularly, however, up to 4 cleaning cycles may be
necessary to fully clean the drive.
Compaq recommends a routine cleaning schedule every 100 hours of use. In
addition, the drive should be cleaned whenever the front panel LCD indicates.
Not all tape drives require the same frequency of cleaning to keep them
operating efficiently. Factors such as the design of the tape drive and the
quality of the tape media used for backups affect cleaning frequency.
Errors Resulting from
Cleaning Neglect
Following are some of the errors that can result from failure to observe routine
maintenance and cleaning of tape drives:
I
Dropouts — Caused by weak signal strength from dirty read/write
heads, a dropout can result in reduced tape capacity and backup
performance.
I
I
Media errors — The backup tapes can be jammed, torn, or otherwise
damaged by a dirty read/write head.
Read or write errors — Because of a dirty read/write head, data may not
have been recorded on the tape during backup. Even if the data is on the
backup tape, retrieval may not be possible if the dirty head cannot read
the data.
I
I
Format failures — During backup, data is laid on the tape in a certain
format for easy retrieval. A dirty write head can cause format failures,
which means that data can be lost or impossible to retrieve.
Bad blocks — Because of media damage (see Media errors above), the
tape may not accept backup data. Also, the read/write head may be
unable to retrieve data from bad blocks.

Importance of Compaq-Approved
Tape Cassettes
Compaq-approved tape cassettes are thoroughly tested to meet high-quality
standards. Before Compaq recommends a tape cassette, the quality and
reliability of the magnetic media and the cassette are evaluated. Do not use
unapproved tape cassettes because they may not be compatible with Compaq
tape drives.
See Chapter 1 for a list of Compaq-approved tape cassettes.
DAT AutoLoader Cleaning
Recommendations
Of the tape drives available today, DAT drives are more susceptible to buildup
of contaminants. If a DAT drive is not kept clean, increased errors will occur.
Recommendations for cleaning DAT drives are as follows:
I
If the CLEANREQ message is displayed on the front panel.
I
When using new tape cassettes, clean the drive heads with a cleaning
cassette after every 8 hours of use for 5 initial cleanings.
I
I
When using tape cassettes that have already been used 5 times, clean the
drive heads with a cleaning cassette after every 100 hours of use.
If you begin to experience read or write errors, format failures, or a
number of bad blocks, clean the head and capstan 3 more times before
concluding that either the tape or the tape drive is defective.
I
In a dusty environment, one cleaning cycle may not fully clean the DAT
AutoLoader drive read/write heads. If backup software reports errors,
clean the drive again. No more than four cleanings will be required to
ensure that heads are fully clean.
NOTE: Cleaning cassettes can be used approximately 50 times. An expired cleaning
cassette will eject immediately without cleaning.
CAUTION: No other periodic maintenance is required. Do Not use alcohol or
cleaning solution to clean DAT drives. Do Not clean read/write heads with a
cotton swab. Fibers from a cotton swab can cause permanent damage to the
head.

5-4 Compaq DAT AutoLoader Reference Guide
Procedure for Cleaning the Heads in
Stacker Mode
1. Place the cleaning cassette into one of the magazine positions (for
example, position 8) and insert the magazine into the DAT AutoLoader.
2. Use the Select button to select the magazine position in which you
placed the cleaning cassette.
3. Press the Enter button to load the cleaning cassette into the drive. The
DAT AutoLoader will then automatically perform a cleaning cycle.
4. At the end of the cleaning cycle, the drive automatically ejects the
cassette and the AutoLoader replaces it in the magazine.
5. Note the date on the label on the cleaning cassette, so that there is a
record of how many times it has been used. After 50 uses, discard the
cassette.
IMPORTANT: If a cleaning cassette is left permanently in the magazine, it will reduce the
amount of data that can be backed up to the magazine, since it will only have seven
positions available for data cassettes.
Procedure for Cleaning the Heads in
Random Mode
1. The host sends a MOVE MEDIUM command to move the cleaning
cassette from the magazine to the drive. The DAT AutoLoader will only
recognize the cleaning cassette once it is loaded into the drive.
2. The drive will then automatically perform a cleaning cycle.
3. The drive automatically ejects the cassette after the cleaning cycle is
complete. The AutoLoader returns the cassette to its magazine position
without further host involvement.
In Random mode, the host can program a routine cleaning cycle (for example,
once a week). The cleaning cassette remains in a set position, such as, position
8, ready for use at the designated time. Remember that this will reduce the
amount of data you can back up to the magazine, since you will only have
seven positions available for data cassettes.
