Purpose
This guide was written for software engineers developing the
application and hierarchical mass storage software that accesses the
ACL 4/52 Automated Tape Library (library). The manual describes the
SCSI-2 software interfaces, discusses performance issues as well as
error handling. The document is divided into the following sections:
Section 1, "Introduction," describes the purpose of this manual,
provides a list of its contents and a list of related documentation.
Section 2, "Theory of Operation," contains detailed discussions of
the Medium Changer Elements, Events, Operational Sequences,
Configuration and Error Recovery Procedures as well as System
Performance and Diagnostic Support issues.
Section 3, "Software Interfaces," describes the specific terminology
of the Small Computer Systems Interface (SCSI-2).
The following conventions are used in this guide:
All binary numbers are succeeded by "b".
All hexadecimal numbers are succeeded by "h".
Error or attention conditions are represented in parenthesis that
translate as follows:
(SK=S ASC=AA ASCQ=QQ)
where:
S = hexadecimal sense key value
AA = hexadecimal additional sense code
QQ = hexadecimal additional sense code qualifier
Definitions of these values are located in Appendix A.
