scope:

This standard defines the command set extensions to facilitate operation of the sequential access device type. This standard, implemented in conjunction with the requirements of the SCSI Architecture Model - 5 standard and the applicable clauses of the SCSI Primary Commands - 5 standard, fully specifies the standard command set for the sequential access device type.

The objectives of this standard are to provide the following:

a) permit an application client to communicate over a SCSI service delivery subsystem, with a logical unit that declares itself to be a sequential access device in the PERIPHERAL DEVICE TYPE field of the standard INQUIRY data (see SPC-5);

b) define commands unique to the sequential access device type; and

c) define commands to manage the operation of the sequential access device type.
