1Introduction

This chapter introduces the DLT-V4 tape drive (tabletop or internal), and provides a general overview of the product.

DLT-V4 Tape Drive Overview 1

The Quantum DLT-V4 tape drive is a value-priced, high-reliability, high­capacity linear streaming data cartridge tape drive designed for use on entry- to mid-range computing platforms. With a combination of data compression and compaction, the DLT-V4 tape drive offers a formatted data cartridge capacity of 320 gigabytes (GB) (assuming a 2:1 compression ratio), and a sustained user data transfer rate of 20 megabytes (MB)/sec (assuming a 2:1 compression ratio).
The DLT-V4 tape drive is a 5¼-inch, half-height form-factor device that uses ½-inch tape. Its design includes a four-channel read/write head, Lempel-Ziv (DLZ) high-efficiency data compression, and a tape-mark directory to achieve fast data throughput and data access times.

Features and Upgrades 1
This section covers the DLT-V4 tape drive features, and information about obtaining drivers and firmware upgrades.

Features 1 The DLT-V4 tape drive offers the following features:

• Supported formats: DLT-V4 (read/write using DLTtape data cartridges), DLT VS160 (read only using DLTtape VS1 Media data cartridges), DLT1/VS80 (read only using DLTtape IV data cartridges).
• Uses DLTtape VS1 data cartridge.
• 5¼-inch half-height form-factor.
• Formatted data cartridge capacity of 160 GB native, 320 GB compressed.*
• Sustained user data transfer rate of 10 MB/s native, up to 20 MB/s with compression*.
®
VS1 Media
• For the SCSI interface tape drive, to achieve 160 MB/s, an Ultra160, or Ultra320, Low-Voltage Differential (LVD) or Single-Ended (SE) Wide SCSI bus is required.
• For the SATA interface tape drive, a SATA interface card is required.
* In accordance with industry practice, a typical compression ratio of 2:1 is
quoted. The redundancy and type of data files being written determine the actual compression ratios achieved.

2Installing the Tape Drive

This chapter explains how to configure and install the tape drive. Configuration and installation are not difficult and require only that you follow the instructions presented in this chapter.

Preparing to Install the Tape Drive 2

This section helps you prepare to install the DLT-V4 tape drive (tabletop or internal).

Before You Start 2 Installing the DLT-V4 SCSI tabletop tape drive requires no special tools.

For the SCSI interface, you will need a ballpoint pen to change the SCSI ID switch on the rear panel of the tape drive.
If you are installing a DLT-V4 SATA internal tape drive, see Installing the
Internal SATA Tape Drive on page 25 for instructions. Installing the DLT-
V4 internal tape drive requires only the usual tools needed to install an internal tape drive in the computer you have chosen to house the tape drive (for example, a screwdriver and some ESD protection).

SCSI Bus Requirements 2 The DLT-V4 SCSI interface tape drive (tabletop and internal) incorporates

a wide Ultra160 low-voltage differential (LVD) small computer system
DLT-V4 Product Manual 4
Chapter 2 Installing the Tape Drive
Preparing to Install the Tape Drive
interface (SCSI) bus, but you can also attach it to a single-ended (SE) SCSI bus.
Make sure the SCSI host adapter or controller supports these configurations. If you connect the tape drive to an SE bus, or if there are SE devices attached to the same SCSI bus, the tape drive’s performance is limited to the maximum data transfer speed and maximum cable lengths of the SE bus (usually 40 MB/s). The DLT-V4 is not compatible with a high- voltage differential (HVD) SCSI bus.

Physical Considerations 2 If you attach the tape drive to a narrow (50-pin) SCSI bus, you must use a

customer-supplied 68-pin to 50-pin adapter that terminates the unused 18 pins. These adapters are sometimes labeled
high-byte termination.
Make sure the total length of the SCSI bus does not exceed the ANSI SCSI standard of 19 feet (6 meters) for an SE SCSI bus, 40 feet (12 meters) for an LVD SCSI bus with multiple devices, or 82 feet (25 meters) for an LVD SCSI bus with a single device.

SATA Requirements 2 The DLT-V4 SATA interface tape drive (internal only) incorporates a

Serial ATA (SATA) bus. Make sure the total length of the internal SATA data cable does not
exceed the SATA standard of approximately 40 inches (1 meter).
DLT-V4 Product Manual 5
Chapter 2 Installing the Tape Drive

Chapter 2 Installing the Tape Drive
Installing the Tabletop SCSI Tape Drive

Unpacking the Tabletop T ape Drive and Selecting a Location

Before you begin, clear a desk or table so that you can unpack the tape drive. You also need to select a location near the server or workstation that has room for the tape drive to sit without being crowded.
2
Note: If the room in which you are working differs from the
temperature at which the tape drive was shipped or stored by 30 ºF (17 ºC) or more, let the tape drive acclimate to the surrounding environment for at least 12 hours before opening the shipping carton.
Unpacking the Tabletop Tape Drive 2
Before you do anything else, unpack and inspect the tabletop SCSI tape drive for shipping damage. If you notice any damage, report it both to the sales representative and to the shipping company immediately.
Note: Save the packing materials in case you need to move or ship
the tape drive in the future. You must ship the tabletop tape drive in the original (or equivalent) packing materials or you will invalidate the warranty.
Selecting a Location for the Tabletop Tape Drive 2
Select a location for the tape drive that is flat, sturdy, level, and close to the server or workstation. A desk or tabletop surface is most suitable. Regardless of the location you choose for the tape drive, make sure the environment is free from dust, cigarette smoke, and excessive temperature and humidity. See the DLT-V4 Product Specification for acceptable operating temperature and humidity limits.
Be sure to follow these additional guidelines when selecting a location for the tape drive:
• Allow at least 6 inches (15.2 cm) behind the tape drive for proper cooling.
• Avoid locations near printers or photocopy machines, both of which produce paper fiber and other types of dust and airborne contaminants.
• Do not place the tape drive on the floor.
DLT-V4 Product Manual 7
Chapter 2 Installing the Tape Drive
Installing the Tabletop SCSI Tape Drive
• Avoid locations near generators, electric motors, audio speakers, or other sources of magnetic fields. Magnetic fields can adversely affect the tape drive and data cartridges.

Setting the SCSI ID 2 All SCSI devices attached to the server or workstation must have a

unique SCSI ID. Check the SCSI IDs on all other devices on the selected server or workstation, including the SCSI host adapter, and select an unused SCSI ID for the tape drive. The factory default SCSI ID for this tape drive is 5, as shown in figure 1
. If the tape drive’s factory default SCSI ID is not already in use by another device on the same SCSI bus, you do not need to change the SCSI ID.

Note: If the selected server or workstation does not already have an
installed SCSI host adapter, you will need to install one. For more information on SCSI host adapter requirements, see SCSI
Bus Requirements on page 4.
To connect the SCSI and power cables to the tape drive, follow these steps:
1 Shut down the operating system and power down the server or
workstation.
2 Power off all peripheral devices, such as printers and other SCSI
devices.
Caution: Do not go to step 3 until you have completed steps 1
and 2
. Failure to follow these instructions may result
in damage to the tape drive or other devices.
3 Obtain a SCSI cable with an open 68-pin, high-density connector. 4 Connect one end of the SCSI cable to one of the connectors on the rear
panel of the tape drive as shown in figure 3 works equally well. Figure 3

Terminating the SCSI Tabletop Tape Drive 2
You must terminate the tape drive if it is the last physical device on the SCSI bus (at the end of the SCSI chain). If another SCSI device is the last device on the SCSI bus, confirm that it is properly terminated and do not terminate the tape drive.
Note: Regardless of which device terminates the SCSI bus, it must
have power applied and be powered on for proper termination to occur.
To terminate the tape drive, locate the terminator in the accessories package and press it firmly into either of the two SCSI connectors on the rear panel of the tape drive. Secure the terminator by tightening the screws until snug. See figure 5
DLT-V4 Product Manual 11
for more details.
Chapter 2 Installing the Tape Drive

Terminating the Internal SCSI Tape Drive 2
If the tape drive is the only SCSI device attached to the selected server other than the SCSI host adapter, or if it is the last physical device on the SCSI bus (at the end of the SCSI chain), you must terminate it. If another SCSI device is the last device on the SCSI bus, confirm that it is properly terminated and do not terminate the tape drive.
Note: Regardless of which device terminates the SCSI bus, that
device must have power applied and be powered on for proper termination to occur.
To terminate the tape drive, install an active LVD/SE cable-end or inline terminator on the SCSI cable you intend to use with the tape drive, as shown in figure 7
. You can use a cable-end terminator or an inline terminator, whichever is most convenient. See the terminator’s instructions for more information.

Note: If the SCSI cable that came with the SCSI host adapter already
has a terminator built into it, do not use another terminator.

panel of the tape drive. The SCSI connectors are keyed, preventing improper connection.
Note: If the SCSI cable does not fit the connector on the SCSI
host adapter, you either have an incompatible SCSI host adapter or you need to purchase a cable adapter. Contact your sales representative or the SCSI host adapter manufacturer for information. See Terminating the
Internal SCSI Tape Drive on page 17 to determine if you
need to use an LVD/SE terminator with the SCSI cable.

This chapter contains information about data and cleaning cartridges.

Data Cartridge Use and Care 5

Your Quantum DLT-V4 tape drive reads and writes DLTtape VS1 data cartridges unless they have been previously written with VS 160 format. Your DLT-V4 tape drive can read (but not write to) DLTtape IV data cartridges previously written with the DLT1/VS80 format and VS1 data cartridges previously written with the VS 160 format.
Note: The tape drive automatically ejects any data cartridges whose
format it cannot read. Make sure all data cartridges that you use for data backup are Quantum DLTtape VS1 data cartridges.

Loading a Data Cartridge 5 Loading a data cartridge into your DLT-V4 tape drive is easy. After the

tape drive completes POST, insert the DLTtape VS1 data cartridge into the cartridge slot, oriented as shown in figure 18 cartridge gently into the tape drive until it stops.

Data Cartridge Use and Care
The Ready LED blinks while the tape drive loads the data cartridge. When the data cartridge is ready to use, the tape drive illuminates the
Ready LED. If the data cartridge is a DLTtape IV written using the DLT1
(VS80) format, the tape drive also illuminates the
Media LED.

Unloading a Data Cartridge

To unload a data cartridge from your tape drive, follow these steps:
5
Caution: Remove the data cartridge from your tape drive before
powering off the tape drive—or the server or workstation for an internal tape drive. Leaving a data cartridge in the tape drive when power is off can result in data cartridge and tape drive damage and may cause data loss because the header/catalog data may not be properly written before the tape drive loses power.
1 Press the Unload/Eject button or use your tape backup software to
unload the data cartridge. The rewinds the tape.
2 When the tape drive has rewound the tape, it ejects the data

Write-Protecting the Data Cartridge

All data cartridges have a write-protect switch to prevent accidental erasure of data. Before loading a data cartridge into your tape drive,
5
make sure to position the write-protect switch on the front of the data cartridge as desired, as shown in figure 20
.
• Write Protected — Slide the switch to the right to write-protect the
data cartridge. A “locked” icon appears on the switch indicating that the data cartridge is write-protected.
• Write Enabled — Slide the switch to the left to allow your tape drive
to write data to the data cartridge. The “unlocked” icon appears on the switch. The indicator on the top of the data cartridge also points to the appropriate icon, indicating the write-protected status. In addition, DLTtape IV cartridges are automatically write protected. DLTtape VS1 cartridges that have been pre-written in a DLT VS160 are automatically write protected.

To ensure the longest possible life for all of your DLTtape VS1 data cartridges, follow these guidelines:
5
• Maintain clean and smoke-free operating and storage environments.
• Do not drop or strike a data cartridge. Excessive shock can displace
the tape leader, making the data cartridge unusable and possibly damaging your tape drive.
• Store your data cartridges in their plastic storage cases.
• Do not expose your data cartridges to direct sunlight or sources of
heat, including portable heaters and heating ducts.
• The operating temperature range for your data cartridges is 10 ºC to
40 ºC (50 ºF to 104 ºF). The storage temperature range is 16 ºC to 32 ºC (60 ºF to 90 ºF).
• If a data cartridge is exposed to temperatures outside the ranges
specified above, stabilize the data cartridge at room temperature for the same amount of time it was exposed to extreme temperatures, up to 24 hours.
• Store your data cartridges in a dust-free environment in which
relative humidity is always between 20% and 80% (non-condensing). The ideal storage relative humidity is 40%.
DLT-V4 Product Manual 57
Chapter 5 Using Data and Cleaning Cartridges
Data Cartridge Use and Care
• Do not place data cartridges near sources of electromagnetic energy
or strong magnetic fields, such as computer monitors, electric motors, speakers, or X-ray equipment. Exposure to electromagnetic energy or magnetic fields can destroy data on data cartridges.
• Place identification labels only in the slide-in slot on the front of the
data cartridge.
• Never use any type of adhesive labels or “sticky” notes on data
cartridges—they can become dislodged inside the tape drive and entangled in the mechanism.
• Do not use graphite pencil, water-soluble felt pens, or other debris-
producing writing instruments on your labels. Never erase a label— replace it.

Using the Cleaning Cartridge

Caution:
Follow the instructions as detailed in Loading a Data
Cartridge on page 54 to load the cleaning cartridge. The
DLT-V4 tape drive will accept only a DLT VS1 cleaning cartridge. Cleaning typically takes several minutes, during which the
Clean LED blinks. If you attempt to load an
inappropriate type of cleaning cartridge, your DLT-V4 tape drive prevents damage by ejecting the cartridge after approximately 25 seconds without allowing the cleaning tape to come into contact with the read/write head.
Use only approved cleaning cartridges in your DLT-V4 tape drive. Use of any other type of cleaning cartridge can damage the read/write head in your tape drive.
