Preface
This document describes the Parallel SCSI, Fibre Channel, and Serial
Attached SCSI (SAS) interfaces for the DLT-S4 tape drive.
Audience This document was written for software engineers developing
application software and hierarchical mass storage software for DLT-S4
tape drives.
It has been designed for use by software engineers who have a basic
understanding of SCSI principles and technology.
Purpose This document provides information about:
• Parallel SCSI, Fibre Channel, and SAS transport layer information
• Task Management by Transport Layer
• All supported SCSI commands
