Overview of the AIT Drive
The Compaq AIT tape drive is a high-capacity data storage device that uses AIT
(Advanced Intelligent Tape) technology. The tape drive provides low-cost, reliable
data protection for entry-level servers, workstations, and desktop computers. With a
backup software application it can provide up to a 2:1 data storage compression ratio.
The AIT tape drive is shipped from the factory with data compression enabled; see
Appendix D for more information on changing this setting.
Requirements
Compaq recommends equipping the computer with a 32-bit Fast SCSI-2 Controller or
higher. Any of these controllers fully supports the AIT tape drive. Install the controller
before beginning the drive installation, using the documentation included with the
controller.
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.
NOTE: This requirement does not apply to the AIT 35 IDE tape drive.
Disaster Recovery Feature
Your new tape drive supports disaster recovery (DR) provided by various Compaq
approved tape backup software vendors. With a few simple steps, your new tape drive
becomes a bootable device that will boot your server and perform an automatic system
restore from an AIT tape cartridge.
DR support for different operating systems is being added and updated frequently. To
learn of the latest operating system support for DR, visit the product page for your
tape drive at www.compaq.com/storage.
For more information refer to the Compaq AIT Drive Documentation CD.

Device Drivers
Drivers for SCSI controllers are located on the Support Software Diskettes and on the
Compaq SmartStart for Servers CD. Tape device driver location depends on the
operating system and third-party software that is being used. The Compaq Native
Drivers CD contains generic drivers for Microsoft-related server products. You can
also download SCSI and tape drivers from the Compaq website at www.compaq.com.
The drivers on downloaded Support Software Diskettes may be newer versions with
new functionality and upgraded utilities.
Refer to the appropriate operating system in this documentation for more details on
tape device drivers.

AIT Drive Reference Guide 25
Installing the Software Drivers
Configuring the SCSI ID for SCO OpenServer
In the preconfigured kernel used to install SCO OpenServer, the following SCSI IDs
are automatically set:
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 will be used during mkdev tape
command.
2. Boot the computer to single user mode and run the mkdev tape command.
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 will appear 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 Getting Started booklet that came with the AIT tape drive for more
information on setting the SCSI ID.
IMPORTANT: The SCO OpenServer install kernel will only communicate 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. The stp driver
is built into SCO UNIX. Consult the SCO System Administrator's Guide for directions
on configuring the SCSI tape driver.

Importance of Using Compaq-Approved Cassettes
Compaq-approved cassettes are thoroughly tested to meet high-quality standards.
Before Compaq recommends a cassette, the quality and reliability of the magnetic
media and the cassette are evaluated. Do not use unapproved cassettes; they may not
be compatible with Compaq tape drives.

IMPORTANT: Compaq only supports media bearing the Compaq logo in Compaq tape drives.
Loading and Ejecting a Cassette
Loading a Cassette
Insert a cassette into the slot on the front panel of the tape drive. As the cassette is
inserted, the drive takes it and automatically loads it into the drive mechanism.
Ejecting a Cassette
The cassette can be removed from the drive either by using a software command or by
pressing the eject button. If you press the eject button, the cassette rewinds before the
drive ejects the cassette from the slot.
NOTE: If the eject button is pressed when the drive is busy, the drive finishes the task it is
engaged in before it responds. This ensures that the task is terminated in a controlled manner
and no data is lost.
34 AIT Drive Reference Guide
Operating the AIT Drive
Forcing the Ejection of a Cassette
CAUTION: You can lose data if you force the ejection of a cassette or the cassette can
end up invalidly formatted because End of Data (EOD) may not have been written.
Force an ejection only as a last resort; never use it as a quick way to eject the cassette.
A cassette can be forced to eject when immediate ejection is required, even at the risk
of losing data. To eject a cassette immediately, hold the eject button down for at least 5
seconds. The cassette is immediately unthreaded and the cassette is ejected, regardless
of what operation the drive was performing.
WARNING: There is a risk of electrical shock. If a cassette is jammed inside the
drive, do not attempt to open the tape drive. Refer all service to a Compaq
authorized service provider.
AIT Drive Reference Guide 35
Operating the AIT Drive
Write-Protecting a Cassette
The cassette has a write-protect switch 1 to prevent accidental erasure of data. Before
loading the cassette into the drive, position the write-protect switch on the front of the
cassette. By moving the switch to SAFE, the cassette is write-protected and by moving
the switch to REC, the cassette is write-enabled.
1
Figure 32: Cassette write-protect switch
NOTE: Your tape switch may differ from the illustration.
Using your fingernail, push the switch in
the direction of the arrow to protect the
tape from writing or accidental erasure.
Return the switch to its original position to
re-enable writing.
Certain AIT cassettes provided by Compaq support Memory in Cassette (MIC). This
feature enables the cassettes to store important cassette information in memory, which
allows faster access to data. MIC cassettes can be easily identified by the gold
connector pads located left of the write-protect switch.
IMPORTANT: The Tape Log, which contains a history of usage of the tape, is not updated
when the cassette is write-protected. The Tape Log becomes inaccurate if a cassette is used
write-protected, and the media warning cannot be relied on to indicate that the cassette needs
to be copied and replaced.
36 AIT Drive Reference Guide
Operating the AIT Drive
Cassette Handling and Storage
For longer life of recorded or unrecorded cassettes, store cassettes in a clean
environment with these conditions:
Keep the cassette out of direct sunlight and away from heaters and other heat
sources.
Store the cassette in temperatures between 5 C and 32 C (41F to 89.6F).
If the cassette has been exposed to conditions outside of the operating
specifications, stabilize it at room temperature for the same amount of time it was
exposed--up to 24 hours.
Do not place the cassette near electromagnetic interference sources, such as video
monitors, motors, magnets, and video or X-ray equipment. Data on the cassette
can be altered.
Store the cassette in a dust-free environment where the relative humidity is
between 20 percent and 60 percent. For longer cartridge life, store the cassette at
20 percent to 40 percent relative humidity.

Cleaning the AIT Drive
Reliable backup of your system is the product of at least four components:
A reliable tape drive
Quality cassettes
Regular backup schedule with backup media stored off-site
Routine tape drive maintenance
Compaq tape drives are designed to operate reliably under worst-case conditions;
however, they require simple routine maintenance to operate efficiently. Regular
cleaning is the most essential step in properly maintaining a tape drive and preventing
errors.
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 1-GB
backups is being used to back up a 10-GB computer, the result on that drive will be
premature aging and reliability problems.
Importance of Routine Cleaning
The tape drive has a cleaning roller built in, which assists in preventing and recovering
from head contamination. This feature minimizes buildup on the read/write heads so
fewer cleaning cycles with a cleaning cassette are required. However, Compaq
recommends a routine cleaning schedule every 100 hours of use to keep the tape drive
in good working order. The drive also needs cleaning when the drive Status LED
displays long flashes with short pauses (see Chapter 3, "Operating the AIT Drive,"
Table 3-2).
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 the tape drive.
AIT Drive Reference Guide 41
Cleaning the AIT Drive
When a drive is cleaned according to a regular schedule, one cleaning cycle typically
removes accumulated dirt and particle deposits. However, in a dusty environment, one
cleaning cycle may not fully clean the AIT drive read/write heads. Up to four cleaning
cycles may be necessary to fully clean the drive.
Errors Resulting from Cleaning Neglect
Failure to observe routine maintenance and cleaning of tape drives can result in the
following errors:
Dropouts
Caused by weak signal strength from dirty read/write heads, a dropout can result
in reduced cassette capacity and backup performance.
Media errors
The backup cassettes 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 be recorded on the cassette
during backup. Even if the data is on the backup cassette, retrieval may not be
possible if the dirty head cannot read the data.
Format failures
During backup, data is laid on the cassette 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 cassette may not accept
backup data. Also, the read/write head may be unable to retrieve data from bad
blocks.
42 AIT Drive Reference Guide
Cleaning the AIT Drive
Tape Drive Cleaning Procedure
CAUTION: Do not use alcohol or a cleaning solution to clean AIT drives. Do not
clean read/write heads with a cotton swab. Fibers from a cotton swab can cause
permanent damage to the head.
1. Insert the cleaning cassette into the drive. The drive automatically takes the
cassette, loads it, and cleans the heads.
When cassette cleaning is finished, the drive ejects it.
2. If the tape drive does not eject the cassette and the Status LED is flashing (see
Chapter 3, "Operating the AIT Drive," Table 3-2), press the eject button, discard
the cassette, and insert a new cleaning cassette.
NOTE: Step 2 indicates the cleaning cassette is exhausted. Throw away the used cleaning
cassette.
After removing the cleaning cassette from the drive, write the cleaning date on the
cassette label. This provides a record of how many times the cleaning cassette has
been used. The cleaning cassette typically has a life of 35 cleaning cycles.
