B1 | Super DLTtape Media

B Using Data Cartridges

B1 Super DLTtape Media

From the outside, the Super DLTtape I cartridge looks very
similar to the DLTtape IV cartridges. The basic geometry,
write-protect switch, and label space are unchanged from the
DLTtape IV cartridge. This simplifies the integration of
Super DLTtape into existing operating environments and
into automated tape libraries.

The Super DLTtape I cartridge is easy to recognize; it has
a different color (green) than the DLTtape IV cartridge
(charcoal gray) and contains a distinctive pattern molded
into the shell. The Super DLTtape I cartridge has a keying
feature to ensure that it cannot be loaded into previous
generation DLTtape drives.

Both the SDLT 220 and SDLT 320 tape drives feature an
optional backward-read compatibility (BRC) mode. When in
BRC mode, the drives are capable of reading DLTtape IV
tapes with DLT 4000, DLT 7000, DLT 8000, and DLT 1
formats. The Backward-Read Compatibility table below lists
BRC rates for the Super DLTtape drive.

B3 Media Care Guidelines

Store data cartridges vertically
in plastic cases.

B3 | Media Care Guidelines

Super DLTtape I data cartridges are engineered to be
reliable, robust, and durable. They are manufactured to
withstand 1,000,000 passes, and have a shelf life of 30 years.
For best results, follow these guidelines for data cartridge
handling and storage:

 Follow the handling instructions and observe the

environmental specifications provided in the plastic
cartridge case.

Use slide-in labels.

 Keep cartridges in their protective cases when not in use.

 Protect cartridges from shock, vibration, moisture, direct

sunlight, dust, smoke, and magnetic fields.

 Do not stack more than five cartridges on top of each

other.

 Store cartridges vertically in protective cases for archival.

 Use the slide-in labels provided. Do not use adhesive

labels or Post-it® notes, and do not write on the cartridge.

 Do not write on the labels with debris-producing writing

instruments, such as graphite pencils and water-soluble
felt pens. Replace labels instead of erasing them.

 Never touch the tape or tape leader. Dust and oils from

your skin contaminate the tape and affect performance.

 Avoid unnecessarily opening the cartridge door to prevent

contamination and physical damage.

 Inspect data cartridges for damage after dropping them.

 B4

 Condition cartridges to the recommended normal

operating environment for 24 hours after exposing them
to abnormal temperature or humidity (such as after
transporting the cartridges from one location to another).

handling of cartridges.

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.

If the cartridge does not pass the following criteria, do not
use it.

To Inspect a Cartridge

1. Inspect the exterior of the cartridge for physical damage

(cracks, broken parts) and contamination (sticky or oily
substances, attached debris).

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 cartridge.

4. 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.

5. Verify that the orange write-protect switch snaps smartly

into position and is not damaged.

6. Open the cartridge door by pressing the tab in the door pivot

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.

SCSI Controller Interfaces | C2

C2 SCSI Controller

Interfaces

You can configure the Super DLTtape drive with one of two
possible SCSI interface cards. These cards can provide one
of three possible SCSI interface types. The multimode
single-ended (MSE) card provides either a low-voltage
differential (LVD) mode running at 80 MB/second or single­ended (SE) mode running at 40 MB/second. The
high-voltage differential (HVD) mode runs at 40 MB/
second.

A single-ended drive only works with a single-ended SCSI
controller card. A differential drive only works with a
differential SCSI controller card.

 Single-ended SCSI interfaces support up to 7 devices on

the SCSI chain using cable lengths up to 3 meters.

 Differential SCSI interfaces support up to 15 devices on

the SCSI chain using cable lengths up to 25 meters.

! A low-voltage differential SCSI interface only works with a

single-ended device if the controller is switched to single­ended mode.

! For more information about SCSI interfaces and SCSI bus

settings, visit www.dlttape.com.

C3 | Setting the SCSI ID

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 220 and SDLT 320
Product Manual.

Each device connected to a SCSI bus must have a unique

3

SCSI ID number. The factory preset SCSI ID is 3 for the
tabletop tape drive and 5 for the internal tape drive. Ensure
that your tape drive’s SCSI ID is unique on your SCSI bus.

! If the drive is the only SCSI device, leave the SCSI ID set

to the default setting.

! Do not use a SCSI ID of 7. This setting is typically

reserved for the SCSI controller.

You can change the SCSI ID using the push-button switch
on the back of the drive. Press the switch buttons above or
below the number display with the point of a pencil to
increase or decrease the ID number.

Connections: Single Drive | C4

C4 Connections: Single

Drive

The Super DLTtape drive performs best when it is the only
device connected to the SCSI bus. If the 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 powered on.

2. Connect a terminator to the upper SCSI connector on the

3

back of the tape drive.

! You must terminate the SCSI bus. The SCSI controller

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 optimum performance, the Super DLTtape drive

should be the only device connected to the SCSI bus.

Using the Power-On Self-Test | D1

D Troubleshooting Tape Drive Problems

D1 Using the Power-On

Self-Test

The Super DLTtape 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 responds BUSY to SCSI
commands.

During this time, 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 220 and SDLT 320 Product Manual
available on the product CD-ROM.

! Do not attempt to open the tape drive enclosure. Only a

qualified Quantum technician should perform service.

D2 | General Troubleshooting

D2 General Troubleshooting

Troubleshoot problems with your tape drive using the
following steps:

1. Visually 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 missing 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. Remove all devices from 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 properly before adding other
devices.

6. 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 these numbers
on the bottom of the tape drive.

D4 | Checking for Tape Drive Errors

D4 Checking for Tape Drive

Errors

The Super DLTtape drive provides status and event
information about the SCSI controller, devices, data transfer,
and errors.

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 information about using the software.

Optimizing the Tape Drive | D5

D5 Optimizing the Tape

Drive

Many factors contribute to Super DLTtape 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 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 adapter does not interact well with the
tape drive.

2. Make sure your controller card and the SCSI bus are

operating in the same mode, preferably 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 Super DLTtape 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.

5. Make sure you are using a data cartridge that is

compatible with the tape drive.  B1
