Quantum SuperLoader 3 Software Interface Guide 7
Chapter 2
2Media Changer Commands
This chapter describes the Media Changer SCSI protocol features
implemented by the Media Changer device of the SuperLoader 3 system.
Note that the sections included in this chapter do not fully reiterate every
ANSI SCSI option and/or command code specification; the sections do
describe the supported commands and options.
Overview of Command and Status Processing
The SuperLoader 3 supports all mandatory SCSI-3 commands and the
Media Changer commands listed in table 1
.
Note: The original SCSI specification allowed users to specify the
LUN (Logical Unit Number) in bits 7 – 5 in byte 1. These
legacy reserved bits are ignored by the autoloader, but will not
be rejected if set.
