Chapter 3 Media Changer Commands
Overview of Command and Status Processing
28 Quantum ATL SuperLoader Software Interface Guide
When conflicts arise between the features of SCSI-2 and SCSI-3, the
SCSI-2 methods have been chosen in all cases where execution
would differ without explicit knowledge of the host. That is, if a
command would act differently in SCSI-3 implementation without
any difference in the actual CDB, the SCSI-2 functionality is used.
If SCSI-3 defined a new functionality of a command but only with
a new field or value for a field as defined by a SCSI-3 document,
this functionality may have been implemented. Please see
individual command descriptions for the SCSI-3 features that have
been implemented.
The SuperLoader device supports the Media Changer commands
