INCITS 497:2012 (R2017)

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.
