INSTALLATION
This chapter provides step-by-step instructions for installing the internal and
external models of the VXA-320 tape drive. The information in this chapter
expands on the instructions in the Quick Start guide that accompanied your
tape drive.
UNPACKING THE TAPE DRIVE
All Tandberg Data tape drives are tested, inspected, and carefully packaged at
the factory. However, because shipping damage can occur, you should follow
the steps below to unpack the tape drive:
UNPACKING THE TAPE DRIVE
2
1. Visually inspect the shipping container and notify your freight carrier
immediately if you see any damage.
2. Place the shipping container on a flat, clean, stable surface. If parts are
missing or the equipment is damaged, notify your supplier or Tandberg
Data.
3. Save the original shipping container and packaging materials in case you
need to reship the tape drive.
INSTALLING THE TAPE DRIVE
The installation instructions for your tape drive depend on what model you
have:
To install the internal LVD SCSI model of the tape drive, read “Installing the

Before You Begin
Before you begin hardware installation, do the following:
1. Select a suitable location for your tape drive—Ensure that the work area is
free from conditions that could cause electrostatic discharge (ESD).
Discharge static electricity from your body by touching a known grounded
surface, such as your computer’s metal chassis.
2. Install an LVD SCSI host bus adapter — Install the LVD SCSI host bus
adapter (HBA) and any necessary drivers in the host computer.
8
PRODUCT MANUAL 433689-01
Page 23
INSTALLING THE TAPE DRIVE
3. Select your backup software application — To obtain information about
which backup software applications work with the tape drive, visit
Tandberg Data’s web site www.tandberg.com You can install the backup
software application on the host computer before or after you install the
tape drive. However, if you install the backup application software first, you
may need to reconfigure it for use with the tape drive.
Caution
! Important
Do not connect the tape drive to an HVD controller. Doing so may damage the
tape drive.
4. Obtain the necessary cables and terminator — The tape drive connects to
the SCSI bus using a cable with a high-density, 68-pin male connector. This
cable must meet the guidelines in “SCSI Cable Requirements,” beginning
on page 41. If the tape drive is the last device on the SCSI bus, you will need
to install an LVD/SE terminator at the physical end of the bus.
5. Do not exceed SCSI bus length restrictions— The maximum allowable
length of an LVD SCSI bus is 12 meters (39 feet) if you have more than two
devices on the bus. Make sure the SCSI bus attached to the tape drive does
not exceed this length. To determine the length of the bus:
Do not connect the tape drive to a RAID controller. The tape drive
will not operate properly if it is connected to a RAID controller.
Although the tape drive’s High-density LVD SCSI interface is
compatible with both single-ended and narrow SCSI buses, to
avoid performance issues Tandberg Data does not recommend
using the tape drive on either of these buses.
If any single-ended device, including a single-ended terminator is
attached to the LVD bus, the result is that all devices on that bus
will run in single-ended mode. Tandberg Data recommends that
you do not use the tape drive on a bus with a single-ended device.
a. Add together the lengths of all external SCSI cables attaching devices on
the bus. External devices are those connected outside of the server’s
enclosure.
b. Add together the lengths of all SCSI cables attaching internal devices on
the bus. Internal devices are those installed within the server’s enclosure.
c. Add together the lengths of all internal cabling for all other SCSI devices
on the bus. Refer to the individual product documentation for cable
length information.
Set the SCSI ID and connect the SCSI cable
1. Power down the computer system.
Turn off all devices attached to the computer in which you plan to install the
tape drive, then turn off the computer. Disconnect all power cables.

2. Prepare the drive bay.
Remove the drive bay’s cover plate according to the system manufacturer ’s
instructions.
3. Set the SCSI ID jumpers, if necessary.
a. The tape drive is shipped with a SCSI ID of 11. If another device on the
SCSI bus is already configured with this SCSI ID, you will need to change
the tape drive’s SCSI ID. Reposition the jumpers on the jumper block, as
shown in Figure 2-2, to select the desired ID. (If necessary, use flat-nose
pliers to remove the jumpers.) If you need an additional jumper, use a
2mm jumper.

Alternatively, you can remove the jumpers and connect a cable (not
included) from a remote switch to the jumper block, then use the remote
switch to set the SCSI ID. The cable should use a connector equivalent to
Hirose Housing part number DF11-8DS-2C, 2.0MM 8CKT to connect to the
jumper block.
! Important
Each device on the SCSI bus must have a unique SCSI ID.
b. Provide additional grounding, if desired.
Attaching the tape drive to the enclosure protects the tape drive from ESD.
However, if you want additional chassis grounding for the tape drive, use
the grounding hole or grounding tab on the back panel (see Figure 2-1):

Caution
Do not use a screw other than the type specified for attaching the grounding wire,
or you may damage the internal components. Screw length must not exceed
5mm.
4. Connect the SCSI cable.
a. Check the connector to ensure that no pins are bent or pushed in before
connecting it to the tape drive.
To avoid damaging the tape drive, make certain you connect pin 1 on the cable to
pin 1 on the tape drive. Pin 1 is on the right, top row of the connector pins (see
Figure 2-3).
b. Connect one of the enclosure’s internal SCSI cables to the SCSI connector
on the back of the tape drive (see Figure 2-3). This cable must meet the
guidelines in “SCSI Cable Requirements,” beginning on page 41.
Note: If desired, you can mount the tape drive (see page 12) before you
connect the SCSI cable, the terminator (if required), and the power
cable to the back. However, if the cables are difficult to access in the
enclosure, you should extend the cables out through the drive bay
and connect them before mounting the tape drive.

CHAPTER 3 OPERATION
USING VXATAPE CARTRIDGES
The tape drive uses data-quality VXAtape data cartridges, in various lengths,
available from Tandberg Data and authorized sources. These cartridges do not
require formatting or other media conditioning before use. See Ta bl e 7 - 1 o n
page 49 for compatibility and capacity information for VXAtape cartridges. See
page 23 for storage guidelines.
Caution
The VXA-320 tape drive only operates with VXAtape data cartridges. Do not
attempt to use other types of cartridges, or you may damage the tape drive.
SETTING THE WRITE-PROTECT SWITCH
Before you insert a cartridge into the tape drive, make sure the write-protect
switch on the cartridge is set correctly, as shown in Figure 3-3.

LOADING A CARTRIDGE
Insert the front of the cartridge through the tape drive door into the loader
mechanism. (The colored write-protect tab on the cartridge should be closest
to the tape drive’s eject button.) Gently push the cartridge until the tape
drive’s loader mechanism activates and completes the tape-loading process.
The tape drive loads the tape in approximately 40 seconds, during which time,
LED 2 flashes green. When LED 2 is steady green, the tape drive is ready to
begin write and read operations.
UNLOADING A CARTRIDGE
To unload a cartridge, press the eject button. The tape drive completes any
command in process, writes any buffered information to tape, rewinds to the
beginning of the tape, and ejects the cartridge in approximately 1 to 2 minutes.
PRODUCT MANUAL 433689-01
Page 37
CLEANING THE TAPE DRIVE
STORING THE CARTRIDGES
If VXAtape cartridges are stored properly, you can expect to successfully
recover data from them for 30 years. Be aware that the 30-year storage life is
for an archival tape, not a tape being used for daily backups.
As a general rule, use a new (or relatively unused) cartridge to store any
critical data you may need to recover many years from now. Do not use a
cartridge that has reached its retirement point. For routine backups that get
overwritten each day or week, it is acceptable to reuse cartridges until they are
ready for retirement.
Proper storage of cartridges helps prevent media-related problems. To ensure
a storage period of 30 years, follow these guidelines:
Remove the cartridge from the tape drive and store it as soon as possible
after you have finished writing or reading data. Avoid handling the
cartridge excessively. Never open the cartridge door or touch the tape.
Label each cartridge.
Set the cartridge write-protect switch to prevent accidental over-writing by
moving the switch to the edge of the cartridge. (See page 22.)
Keep each cartridge in its protective case or a container designed for
cartridge storage.
Store cartridges away from copiers and printers to avoid contamination by
toner and paper dust.
Store cartridges away from objects or devices that emit strong magnetic
fields.
CLEANING THE TAPE DRIVE
This section describes when and how to clean the tape drive to maintain
optimal performance. Circulating air may introduce debris into the tape path.
If debris builds up on the heads, error rates increase and backups take longer
because the tape drive must rewrite the data. The VXA-320 tape drive includes
an internal cleaning wheel to remove contamination from the tape path.
However, you should still clean the tape drive regularly with a separate
cleaning cartridge to maximize tape drive reliability and the life of your tapes.
DETERMINING WHEN TO CLEAN THE TAPE DRIVE
When the tape drive requires cleaning, LED 2 flashes amber. The tape drive
should be cleaned as soon as possible after this LED begins flashing.
Note: Some software applications may notify you that the tape drive requires
cleaning. Refer to your software documentation for more information.

CHAPTER 3 OPERATION
USING A CLEANING CARTRIDGE
Insert a VXAtape Cleaning Cartridge into the tape drive. The tape drive
automatically performs the cleaning cycle in less than one minute. When
finished, the tape drive ejects the cleaning cartridge and LED 2 turns off.
Note: If there are no more cleaning cycles remaining on the cleaning cartridge,
the tape drive ejects the cartridge without performing the cleaning and
LED 2 flashes green and amber.
Caution
Do not use any cleaning method other than the VXAtape Cleaning Cartridge (or a
cleaning cartridge approved by Tandberg Data for use with VXA tape drives). Using
other cleaning methods may void the tape drive’s warranty.
Do not rewind and reuse the material in a cleaning cartridge. Reuse may
redistribute contaminants previously removed from the tape path. If all cleaning
material has been used, discard the cartridge and use a new cleaning cartridge.
RESETTING THE TAPE DRIVE
To reset the VXA-320 tape drive, perform one of the following steps:
Press and hold the unload button for at least 10 seconds, then release the
button. This clears any error, ejects any cartridge that is in the tape drive
(unless a hardware error occurred), and resets the tape drive.
Note: If the tape drive contains a cartridge, the tape drive rewinds the tape
Power down the tape drive. Wait 10 seconds, then turn the tape drive back
on. Depending on what function the tape drive was performing before the
reset, the tape drive may automatically start a lengthy format recovery
process, which involves reading the data to determine where the end of data
is located. This may take as long as 2 to 3 hours. Wait for the format recovery
to complete.
to the beginning before ejecting the cartridge. The time required to
complete the rewind depends on what size cartridge you are using
and if the tape was positioned near the end.

also provides helpful troubleshooting tips.
TAPE DRIVE WILL NOT ACCEPT A CARTRIDGE
If the tape drive does not accept a cartridge when you insert it into the tape
drive door, do the following:
1. Determine if there’s already a cartridge loaded.
Press the eject button; there may be a cartridge already loaded in the tape
drive.
2. Make sure you are using VXATape cartridges with either VXA-2 or VXA-320
(VXA-3) format.
If the cartridge you are attempting to load is not a VXATape cartridge, the
tape drive automatically ejects it.
If the cartridge contains data written in VXA-1 format, the tape drive
automatically ejects it. The front panel LEDs indicate an unrecoverable
error (LEDs 1 and 3 are amber, LEDs 2 and 4 are off).
3. Check that the tape drive is powered on and that it is not indicating an error
state on its LEDs. Refer to Ta b l e 3 - 1 o n pa g e 2 0 for a complete list of LED
states.
4. Check to see if LED 4 is flashing orange, indicating that the tape drive is
over-temperature (see “LED 4 is Flashing Orange” on page 26).
5. Power cycle the tape drive.
Power down the tape drive. Wait 10 seconds, then turn the tape drive back
on.

Block Mode.
If a firmware upgrade was interrupted or did not complete successfully, the
tape drive powers on in Boot Block Mode. Reload the firmware as described
in “Upgrading Firmware” on page 36. The tape drive will not accept a
cartridge until the firmware is successfully reloaded.
LED 4 IS FLASHING ORANGE
If LED 4 is flashing orange, the tape drive is over temperature and must cool
down before operations can continue. Do the following:
1. Wait for the tape drive to cool.
When the tape drive cools down, LED 4 turns off. Do not attempt to load a
cartridge or perform any operations during this time. If there is a tape
loaded in the tape drive, press the eject button to unload the tape and move
it to a cooler environment.
2. If necessary, power cycle the tape drive.
If the tape drive does not cool down on its own, power down the tape drive.
Wait a few minutes, then turn the tape drive back on. If LED 4 is still orange
after power-up, the tape drive may be in an environment that is too hot.
If the tape drive is an internal model, check that the ventilation fan on
the back of the tape drive is not obstructed and that the tape drive is not
located near devices that are emitting excessive heat.
If the tape drive is an external model, check that the ambient
temperature is within the specifications noted in Ta b l e 7 - 1 6 o n p a g e 5 8 .
If the temperature is within the specifications, the enclosure’s fan may
not be working properly and you should return the tape drive for
service (see page 35).

RESOLVING PROBLEMS
TAPE DRIVE WILL NOT EJECT A CARTRIDGE
If the tape drive does not eject a cartridge when you press the eject button, do
the following:
1. Use your backup application to eject the cartridge.
To protect against accidental tape ejection during a backup or restore
operation, many applications prevent using the tape drive’s eject button for
media removal.
2. If you cannot eject the cartridge through the application, use VXATool to
unload the cartridge. Refer to the readme file or on-line help available with
VXATool for instructions.
3. Reset the tape drive. Press and hold the unload button for at least 10
seconds, then release the button. This clears any error, ejects any cartridge
that is in the tape drive (unless a hardware error occurred), and resets the
tape drive.
Note: If the tape drive contains a cartridge, the tape drive rewinds the tape
to the beginning before ejecting the cartridge. The time required to
complete the rewind depends on what size cartridge you are using
and if the tape was positioned near the end.
4. Power cycle the tape drive.
Power down the tape drive. Wait 10 seconds, then turn the tape drive back
on. Depending on what function the tape drive was performing before the
reset, the tape drive may automatically start a lengthy format recovery
process, which involves reading the data to determine where the end of
data is located. This may take as long as 2 to 3 hours. Wait for the format
recovery to complete.
5. If the cartridge appears to be stuck in the tape drive, return the tape drive
for service.
If you still cannot eject the cartridge, you may need to return the tape drive
for repair with the cartridge in place.

BACKUP APPLICATION IS REPORTING AN ERROR
Your backup application may report an error as a result of a failure to
communicate with the tape drive, a failure by the tape drive to write or read
data, or because of a software configuration issue.
Failure to communicate with the tape drive
Communication problems on the SCSI bus may be reported by the backup
application as resets, a loss of communication with the tape drive, failure to
detect the tape drive, I/O device errors, or parity errors. These types of errors
may occur intermittently. Most often, these issues are due to SCSI cabling and
termination problems.
Check tape drive installation on the SCSI bus, described in “Installing the
Internal SCSI Tape Drive” on page 8 or “Installing the External SCSI Tape
Drive” on page 14.
Use VXATool to capture the diagnostic log from the tape drive immediately
after an error is reported by your backup application. Technical Support can
examine the log to determine the nature of the reported error. Refer to
“Capturing a Diagnostic Log” on page 31 for instructions.
OCTOBER 2006 VXA-320 TAPE DRIVE

Page 44
CHAPTER 4 TROUBLESHOOTING
Failure by the tape drive to write or read data
If your backup application reports a media error, one of the following
situations may have occurred:
The tape drive needs cleaning (see “Cleaning the Tape Drive” on page 23).
Always try cleaning the tape drive before you assume the cartridge is bad.
Be sure to use a VXAtape Cleaning Cartridge.
The cartridge needs to be replaced. Try using a different cartridge for the
backup, making sure that the tape is not written in VXA-1 format. Mark any
cartridge that fails. If you notice that the same cartridge results in multiple
failures, it may be time to replace the cartridge.
The backup application has attempted to append data to a cartridge that
previously failed. If a write media error previously occurred on the tape, the
tape drive cannot append data at the point where the write media error
occurred. You can attempt to overwrite the tape, but any attempt to append
data will fail.
If you are trying to write data, the cartridge may be write-protected. Check
the switch on the edge of the cartridge (see Figure 3-3 on page 22). If the
switch does not cover the opening, the tape is write-protected. If the switch
covers the opening, you can write to the tape. Use a pen or small screwdriver
to move the switch.
If you used an application other than your normal backup application to
write data to the tape, your backup application may report that it does not
recognize the tape. For example, if you have used VXATool to write and read
test data, the test tape will not be “recognized” by your backup application.
Perform a tape erase using either VXATool or your backup application.
Backup Application configuration issues
If you suspect an issue with the backup application configuration, use
VXATool to first confirm that the hardware is working properly. Run a
VXATool Write/Read test to verify that the tape drive is communicating over
the SCSI bus and that it can perform write and read operations. The readme
file that accompanies the program (or the online help for the Windows
version) provides instructions for using VXATool.
For any questions regarding software configuration, contact your software
provider.

COMMUNICATION INTERFACE VERSUS COMMAND PROTOCOL

COMMUNICATION INTERFACE
AND COMMAND PROTOCOL
This chapter provides an overview of the communication interface and
command protocol used by the VXA-320 (VXA-3) tape drive. It includes the
following topics:
Communication interface versus command protocol SCSI communication interface SCSI interface requirements SCSI command protocol
COMMUNICATION INTERFACE VERSUS COMMAND PROTOCOL
When a device is connected to a host computer, their interaction is
accomplished via a communication interface (for example, a parallel SCSI bus).
The communication interface is comprised of the physical interface (for
example, cables, connectors, and control circuitry) and the signaling protocol
used during communication.
The physical interface determines the number of devices that can be attached
to a bus or network loop, the maximum length of the cables, and the physical
characteristics of the cable itself (for example, the number of wires, shielding,
and so forth). The signaling protocol defines the electrical characteristics and
timing of signals carried by the cable, the message system requirements,
transmission speeds and maximum data transfer rates, as well as the encoding
and decoding of the individual bit patterns representing commands passing
between the individual devices.
OCTOBER 2006 VXA-320 TAPE DRIVE
37
Page 52
CHAPTER 6 COMMUNICATION INTERFACE AND COMMAND PROTOCOL
The format and content of the information carried over the communication
interface, as well as how each device uses and responds to the information, is
governed by a command protocol. The command protocol determines how the
host (or initiator) interacts with the target device (for example, the tape drive)
by issuing commands to control its operation, transferring data, and
responding to status information. The target device responds to commands
from the host by performing the requested operation (for example, writing or
reading data on magnetic tape) and returning status information.
The VXA-320 tape drive is available with a parallel SCSI communication
interface. This communication interface provides a method of passing SCSI
command descriptor blocks (CDBs) over an bus. The operation of the tape
drive is governed by the SCSI command protocol.
The following section describes how the SCSI communication interface is
implemented in the tape drive. “SCSI Interface Requirements” on page 40
describes the physical requirements of the SCSI bus. “SCSI Command
Protocol” on page 44 provides information about the SCSI command protocol
used by the tape drive. Refer to the VXA-320 (VXA-3) Tape Drive SCSI Reference
for detailed information about the SCSI communication interface and
command protocol.
SCSI COMMUNICATION INTERFACE
This section provides an overview of the SCSI communication interface used
by the VXA-320 tape drive.
SCSI BUS PHASES
Bus phases determine the direction and type of information transferred across
the data lines of the SCSI bus. The possible bus phases include Bus Free,
Arbitration, Selection, Reselection, and Transfer (which includes four subsets:
Message In or Message Out, Command Out, Data In or Data Out, and Status
In). Ta b l e 6 - 1 describes the bus phases.
Table 6-1 SCSI bus phases and information transfer phases
Bus Phase Description
Bus Free The Bus Free phase specifies that no device is using the bus.
Arbitration The Arbitration phase allows devices to compete for access on the bus.
Selection The Selection phase allows an initiator to select the tape drive for communication.
Reselection The Reselection phase allows the tape drive to reconnect to the initiator after it
disconnects.

The Message phases help manage the physical path between the initiators and targets.
In the Message In phase, the tape drive sends a message to the initiator. In the Message
Out phase, the initiator sends a message to the tape drive.
In the Command Out phase, the initiator sends a command to the tape drive.
Commands contain information about what actions the tape drive should perform.
In the Data In phase, the tape drive transfers data to the initiator. In the Data Out
phase, the initiator transfers data to the tape drive.
In the Status In phase, the tape drive returns a status byte to the initiator. The status
byte indicates the results of the command’s execution.
SCSI MESSAGE SYSTEM
The SCSI message system allows communication between a SCSI initiator and
the VXA-320 tape drive for interface management. This message system or
command set is separate from the SCSI command protocol used to control the
operation of the tape drive. A message can be one byte or multiple bytes.

Description
SCSI INTERFACE REQUIREMENTS
The VXA-320 tape drive is available with a wide, High-density (HD) 68-pin,
low-voltage differential (LVD) SCSI interface. This section provides general
information about the specifications for the tape drive’s Small Computer
System Interface (SCSI), including:
SCSI cable requirements
SCSI connector requirements
Terminator requirements
! Important
Although the tape drive’s High-density, 68-pin LVD SCSI
interface is compatible with both single-ended and narrow SCSI
buses, to avoid performance issues Tandberg Data does not
recommend using the tape drive on either of these buses.

SCSI INTERFACE REQUIREMENTS
INTERNAL TAPE DRIVE
This section describes the cable, connector, and terminator requirements for
the internal High-density, 68-pin LVD SCSI tape drive.
SCSI Cable Requirements
The cable connected to the tape drive SCSI connector must meet the SCSI-3
specifications listed in Ta b l e 6 - 3 .
Caution
Using a noncompliant SCSI cable will degrade VXA-320 performance and can
cause random, nonreproducible errors. Tandberg Data recommends using shielded
cables.
Table 6-3 SCSI cable and connector specifications
Specification Requirement
General Wide, LVD SCSI-3
Connector High-density, 68-pin, male
Maximum length
Stub length
a
12 meters (39.2 feet)
No greater than 0.1 meters should be used off the mainline connection within any
connected equipment.
The stub length within the tape drive is less than 2.5 centimeters (1 inch).
Impedance Between 90 and 140 ohms.
An impedance of greater than 100 ohms is recommended. To minimize
discontinuities and signal reflections, all cables on the bus should have the same
impedance.
Conductor size 28 AWG (0.08097 mm
2
)
A minimum of 28 AWG will minimize noise effects and ensure proper distribution of
terminator power.
a
The maximum length of 12 meters only applies to an LVD SCSI bus. If a single-ended device is connected anywhere on the bus, all devices
on the bus operate in single-ended mode. When operating in single-ended mode, the maximum allowable bus length is 3 meters
(9.8 feet), terminator to terminator. Exceeding the maximum cable length will result in unstable and unpredictable operation.

SCSI INTERFACE REQUIREMENTS
SCSI Terminator Requirements
If the internal tape drive is the last device on the SCSI bus, you must terminate
the bus by installing an pass-through LVD/SE terminator on the tape drive’s
SCSI connector. Or, if there is an unused connector at the end of the SCSI
cable, you can terminate the bus there. If the cable provided with your adapter
has a built-in terminator, do not add another terminator to the bus.
Note: If you will be installing the tape drive in an enclosure and using an external
terminator, you must install a high-quality active LVD terminator that
complies with the SCSI-3 specification.
EXTERNAL TAPE DRIVE
This section describes the cable, connector, and terminator requirements for
the external LVD SCSI tape drive.
SCSI Cable Requirements
For the external tape drive, select a cable that complies with the SCSI-3
specification and meets the requirements listed in Ta b l e 6 - 5 .
Table 6-5 SCSI cable requirements
Specification Requirement
Connector type 68-pin male, high-density, shielded, SCSI-3 compliant
Maximum length
a
The maximum length of 12 meters only applies to an LVD SCSI bus. If a single-ended device is connected
anywhere on the bus, all devices on the bus operate in single-ended mode. When operating in
single-ended mode, the maximum allowable bus length is 3 meters (9.8 feet), terminator to terminator.
Exceeding the maximum cable length will result in unstable and unpredictable operation.

Air Flow/Cooling Requirements
When mounted in the host enclosure, the tape drive must have adequate air
flow. Ensure that ambient air is allowed to pass through the ventilation holes
shown in Figure 3-1 on page 19. These ventilation holes must not be blocked.
The air flow around the tape drive must be sufficient to prevent tape path
temperatures from exceeding 45 °C (113 °F).
The tape drive is equipped with a temperature sensor. It issues an
overtemperature signal through the LOG SENSE command if the above
temperature is exceeded. You can access temperature data through the LOG
SENSE command. See the VXA-320 (VXA-3) SCSI Reference Manual.
