Quantum DLT 4000 Tape Drive

ABOUT THIS MANUAL

“About this Manual” outlines the scope and contents of this manual. It contains information about
the intended audience, purpose of the manual, document organization, and document conventions.

AUDIENCE

This manual is written for original equipment manufacturers (OEMs) that are

integrating the Quantum DLT4000 tape drive and into a system or subsystem.

Its primary audience is the OEM technical staff that makes tape drive purchase
and configuration decisions, and system integrators that are responsible for the
SCSI interface. Additionally, the manual can be used by technically astute end­users for installation and operation of the tape drive, although that is a
secondary audience.

PURPOSE

This manual describes the rackmount and tabletop versions of the DLT 4000
tape drive. It is intended to provide the information necessary to integrate the
tape drive into a computer system or subsystem.

DOCUMENT ORGANIZATION

This product manual contains five chapters, a number of appendixes of related
useful information, and an index. It includes an overview of the Small Computer
System Interface (SCSI) and detailed descriptions of the messages and SCSI
commands as used by the tape drive. The manual is organized as follows:

Chapter 1 General Description and Specifications

This chapter contains a brief description of and specifications for the
drive.

Quantum DLT 4000 Tape Drive xxi

About This Manual

Chapter 2 Hardware Implementation

This chapter contains configuration and installation information for the
tape drive, descriptions of the drive controls and LEDs, and information
on running the self-test.

Chapter 3 SCSI Description

This chapter provides a detailed description of the logical interfaces of
the tape drive. It describes the products’ compliance with the ANSI
SCSI-2 specification. The drive’s many optional features are described
here and throughout the manual.

Chapter 4 Messages

This chapter provides a list and description of most messages supported
by the tape drive. The SCSI message system allows communication
between SCSI initiators and SCSI targets (the tape drive, in this case)
for interface management and for command elaboration and
qualification.

Chapter 5 SCSI Commands

This chapter describes in detail each command supported by the tape
drive. The SCSI command system enables an initiator to direct a tape
drive to perform a wide range of operational and diagnostic functions.
This chapter also provides sense key information for the REQUEST
SENSE SCSI command.

Appendix A Definition of Vendor Unique Sense Data Information

Appendix A provides a list of internal status codes related to the
REQUEST SENSE SCSI command.

Appendix B EEPROM-Resident Bugcheck and Event Logs

Appendix B provides an explanation of the error and event logs stored in
semi-permanent, non-volatile memory.

Appendix C Updating the Firmware

Appendix C provides a step-by-step procedure for updating a tape drive’s
PCBA controller-resident firmware.
