Inspecting Data Cartridges | B4
B4 Inspecting Data
Cartridges
Check reel locks.
Inspect spring-loaded hub for
proper tension.
Check for toed-in clips.
Improper data cartridge handling is the primary reason for
tape drive problems. To avoid losing data or damaging the
tape drive, inspect cartridges:
Before loading a new cartridge
After dropping a cartridge or subjecting it to physical
shock
When the tape drive becomes inoperable after loading a
cartridge
When you receive a shipment of data cartridges that
shows any sign of shipping damage.
Use the following procedure to inspect a cartridge. If the
cartridge shows any sign of damage, do not use it.
To Inspect a Cartridge
1. Inspect the exterior of the cartridge for physi cal damage
(cracks, broken parts) and conta mination (sticky or oily
substances, attached debr is).
2. Gently shake the cartridge. Listen for loose pieces.
3. Check that both reel locks on the cartridge are visible. One
reel lock is located on the end of the cartridge that is
inserted into the tape drive. The other is on the bottom of
the cartridg e.
4. Confirm that the spring-loaded hub on the bottom of the
cartridge is cente red. Press the hub to ensure that the spring
is functioning properl y and t hat the hub retur ns to i ts n ormal
position.
5. Verify that the orange write-protect switch snaps sma rtly
into position and is not damaged.
6. Open the cartridge door by pr essing the ta b in the d oor pivo t
notch. Check for possible damage to the tape leader buckle,
including a bent or toed-in appearance or improper seating.
7. Examine the visible tape leader (without touching it) for
excessive debris, oily or sticky residue, condensed droplets
of moisture, or any other signs of contamination.
Note: For more detailed and thorough information about
inspecting a data cartridge, refer to the SDLT 600
Product Manual.

C1 | Understanding the Tape Drive’s Interface
C Connecting the Tape Drive
C1 Understandi ng the Tap e
Drive’s Interface
The tabletop model of the SDL T 600 tape dr ive has an Ultra 160
SCSI interface. The internal model has either a Fibre Channel
interface or an Ultra 160 SCSI interface.
The Ultra 160 SCSI Interface
Ultra 160 provides a low-voltage differential (L VD) mode
running up to 160 MB/second and a single-ended (SE) mode
running up to 40 MB/second.
Note: The host computer’s SCSI controller c ard may limit the se
speeds. For the best performance, make sure the SCSI
controller card can operate at 160 MB/second.
The tape drive automatically senses the SCSI bus mode and
switches between LVD and SE accordingly. Although the tape
drive defaults to LVD, it switches to SE if the SCSI bus operates
in SE mode. For example, if the SCSI controller card is SE (or
multi-mode set to SE), the tape drive automatically switches to
SE mode. Also, if any device on the SCSI bus is SE, the entire
bus switches to SE, including the tape drive.
In SE mode, the SCSI bus can support up to 7 devices using
cable lengths up to 3 meters. In LVD mode, the SCSI bus can
support up to 15 devices using cable lengths up to 25 meters.
For more information about using the SCSI interface, refer to
the SDLT 600 SCSI Interface Guide.
The Fibre Channel Interface
The Fibre Channel interface runs at speeds up to either
1 Gb/second or 2 Gb/second, depending on the configuration
you choose during installation.
Fibre Channel can support up to 126 devices in a loop
configuration. Longwave transceivers (with fiber optic cable)
support distances up to 10 kilometers; short pulsewave
transceivers (with fiber optic cable) support distances up to 500
meters.
For more information about using the Fibr e Channel interface,
refe r t o th e SDLT 600 Fibre Channel Interface Guide.
Choosing Cables and Connectors | C2
F
C2 Choosing Cables and
Connectors
This section describes the cables and connectors to use with
the SDLT 600 tape drive.
SCSI Cables and Connectors
SCSI versions of the SDLT 600 tape drive have two highdensity 68-pin SCSI connectors. Connect the tape drive to
the host computer using a SCSI ca ble with the correct type of
connector on each end. The tape drive operates best when the
host computer and host end of the cable have one of the
following types of connector.
SCSI Connectors
iber Optic Cable
High-density 68-pin Micro DB68 or Mini DB68
SCA 80-pin Hot Swap Connector
Very High-density Interconnect Connector
The tape drive will, however, operate with other host-end
connectors.
Fibre Channel Cables and Connectors
Fibre Channel versions of the SDLT 600 tape drive
(internal model only) have one Fibre Channel port. The Fibre
Channel port is equipped with a Small Form- fac tor,
Pluggable (SFP) converter for connecting the fiber optic
cable. You may have to supply the SFP for the other end of
the cable; some host bus adapters have the transceiver
already built in to the adapter, in which case, you do not have
to supply the SFP for the other end of the cable.
Note: Both ends of the cable require a transceiver.
C3 | Setting the SCSI ID
3
C3 Setting the SCSI ID
This section describes how to set the SCSI ID on the tabletop
tape drive. For information about setting the SCSI ID on an
internal tape drive, refer to the SDLT 600 Pr oduct Manual.
Each device connected to a SCSI bus must have a unique
SCSI ID number. The factory preset SCSI ID is 3 for the
3
tabletop tape drive and 5 for the internal tape drive. Ensure
that your tape drive’s SCSI ID is unique on your SCSI bus.
Y ou can change the SCSI ID using the push-button switch on
the back of the tape drive. Use the point of a pencil to press
the buttons above or below the number display to increase or
decrease the ID number.
! If the tape drive is the only SCSI device, leave the SCSI ID
set to 3, the default setting.
! Do not use a SCSI ID of 7. This setting is typica lly
reserved for the SCSI controller.
Connecting the SCSI Model as a Single Device | C4
C4 Connecting the SCSI
Mode l as a Si ngl e Devi ce
The SDLT 600 tape drive performs best when it is the only
device connected to the SCSI bus. If the SDLT 600 tape
drive is the only SCSI device you intend to connect to the
SCSI bus, follow these steps:
Terminate upper
SCSI port.
1. Make sure the host computer and all peripheral devices
are powered off.
! Never connect the tape drive while the host system or
peripheral devices are powe red on .
2. Connect a terminator to the upper SCSI connector on the
3
back of the tape drive.
! Yo u mus t terminate the SCS I bus. The SCSI contr oller
terminates one end, while a terminator on the tape drive
terminates the other end.
3. Connect one end of the SCSI cable to the lower
connector on the back of the tape drive.
4. Connect the other end of the SCSI cable to the SCSI
connector on the host computer.
For more information about connecting the SDLT 600 tape
drive, refer to th e SDL T 600 Pr oduct Manual.

3. Connect the SCSI cable from the host computer to the
lower SCSI connector on the back of the tape drive.
4. Continue the SCSI chain using the upper SCSI
connector.
5. If the SDLT 600 tape drive is the last device in the
chain, connect a terminator to the upper SCSI connector.
! Yo u mus t terminate the SCS I bus. The SCSI contr oller
terminates one end, while a terminator on the last device
in the chain terminates the other end.
For more information about connecting the SDLT 600 tape
drive, refer to th e SDL T 600 Pr oduct Manual.
Connecting the Fibre Channel Model | C6
C6 Connecting the Fibre
Channel Model
The Fibre Channel protocol and the SCSI protocol rely on
different methods of addressing devices. Unlike the SCSI
protocol, which uses fixed SCSI IDs , the Fibre Channel
protocol uses different addressing depending on the type of
topology used for the network: point-to-point, arbitrated
loop, or fabric. The addresses are set dynamically (in real
time) at the time the device attaches to the network.
Follow these steps to connect a Fibre Channel SDLT 600
tape drive:
1. Insert a fiber optic cable into the Fibre Channel port on
the back of the tape drive.
The connector is fully seated when it snaps into the port.
! Y ou can connect a Fibre Channel connector while the tape
drive is still powered on; this capability is known as “hotswappable” or hot-pluggable.”
2. Optional step (for this step, rely on your judgement
based on your knowledge of the host bus adapter that
you are currently using): Attach an SFP connector
C2) to the other end of the fiber optic cable before
(
connecting it to the host device.
For more information about c onnecting a Fibre Channel tape
drive, refer to th e SDL T 600 Pr oduct Manual.
D1 | Using the Power-On Self-Test
D Troubleshooting Tape Drive Pr oblems
D1 Using the Power-On
Self-Test
The SDLT 600 tape drive performs a self-diagnostic test,
called a Power-On Self-Test (POST), each time you power it
on. This test helps you detect problems with your tape drive.
POST completes in approximately 10 seconds. While POST
is in progress, the tape drive re sponds BUSY to SCSI
commands.
If the host computer attempts to negotiate synchronous or
wide transfers, the tape drive negotiates to asynchronous or
narrow. It may take longer than the duration of POST for the
tape drive to become ready.
During POST, each LED lights in sequence. When POST is
complete, the green Drive Status LED lights steadily.
If the tape drive fails POST, check for the following possible
problems:
There is no cartridge in the tape drive .
The tape drive is not receiving adequate power (try a new
cord or different outlet).
The tape drive is not properly connected to the host
computer and other SCSI devices.
If any of these problems exist, correct the problem, power
off the tape drive and power it back on to restart POST. If
none of these problems exists or the tape drive fails POST
after you have corrected them, refer to additional
troubleshooting information in the SDLT 600 Product
Manual available on the product CD-ROM.
! Do not attempt to open the tape drive enclosure. Only a
qualified Quantum technician should perfo rm servi ce.
General Troubleshooting | D2
D2 General Troubleshooting
Troubleshoot problems with your S DLT 600 tape drive using
the following steps:
1. Visua lly inspect the cartridge for damage, and try a new
cartridge if necessary. B4
2. Make sure the cables and connectors are in good
condition. For example, check that they are not worn
or broken, and there are no mis sing or bent pins.
3. Make sure the connector on each end of the cable is fully
seated.
4. Disconnect the tape drive from the host system, power
off the tape drive, and power it on again to perform a
POST. D1
5. If you have a SCSI tape drive, remove all devices f rom
the SCSI bus. Connect the tape drive directly to the host
computer and terminate it ( C4). Confirm that the tape
drive and host computer are communicating proper ly
before adding other devices.
6. If you have a Fibre Channel tape drive, look at the back
panel to see if the green LED (the “link light”) there is
illuminated ( C6). If the link light is illuminated, you
have a working connection with the Fibre Channel
network.
7. Ensure that your operating system (modules, patches,
and drivers), backup software, and tape drive are
compatible. Visit www.quantum.com/sdlt for the most
current compatibility information.
If you cannot identify or correct the problem, call Quantum
Technical Support at 1-888-827-3378. Have your model and
serial number available when you call. Find thes e numbers

Checking for Tape Drive Errors | D4
D4 Checking for Tape Drive
Errors
The SDLT 600 tape drive (SCSI version) provides status and
event information about the SCSI controller, devices, data
transfer, and errors. The Fibre Channel version of the tape
drive also indicates whether a signal is present and provides
the Fibre Channel address, speed, topology, and node and
port information.
You can use iTalk to access this information through the tape
drive’s infrared port located on the front of the tape drive.
You can find iTalk on the CD-ROM that accompanies the
tape drive, or you can download it from
www.quantum.com/sdlt
(you must first register your tape drive on the web site). See
iTalk’s online help for inf orma tion about using the software.
D5 | Optimizing the Tape Drive
D5 Optimizing the Tape
Drive
Many factors contribute to SDLT 600 tape drive
performance. Host system considerations include processor
speed, block size, SCSI adapter performance, bus
configurations, and software.
If you are concerned about the performance of your
SDLT 600 tape drive, check the following:
1. Ensure that your tape drive is properly defined for the
host system. If the tape drive is not defined within the
system, the SCSI adapte r does not inte ra ct we ll with the
tape drive.
2. Make sure your controller card and the SCSI bus are
operating in LVD. If the controller card or the SCSI bus
are operating in SE, the tape drive switches to SE.
3. De-fragment your hard disk on a regular basis.
Fragmented disks and files take much longer to back up.
4. Check your host block size. The SDL T 600 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 s i ze,
which results in poor performance.
5. Make sure you are using a data cartridge that is
compatible with the tape drive. B1
