Information Technology – Automation/Drive Interface Commands - 3 (ADC - 3)
|Publication Date:||27 November 2012|
This standard defines the model and command set extensions to facilitate operation of automation/drive interface devices. The clauses of this standard, implemented in conjunction with the applicable clauses of SPC-4, fully specify the standard command set for automation/drive interface devices.
The objective of this standard is to:
a) permit an application client to communicate over a SCSI service delivery subsystem, with a logical unit that declares itself to be an automation/drive interface device in the PERIPHERAL DEVICE TYPE field of the standard INQUIRY data (see SPC-4);
b) define commands unique to the automation/drive interface device type; and
c) define commands and parameters to manage the operation of the automation/drive interface device type and the operation of logical units of other specific device types that are present in the same device as the automation/drive interface logical unit.
The SCSI document structure in figure 1 is intended to show the general applicability of the documents to one another. Figure 1 is not intended to imply a relationship such as a hierarchy, protocol stack, or system architecture.
Commands in this standard do not require the use of a specific SCSI transport protocol.
