Nosaukums<p>This part of ISO/IEC 14776 defines the command set extensions to facilitate operation of SCSI</p> <p>block devices.</p> <p>It specifies the functional requirements for the SCSI-Block Command set (SBC). SBC permits</p> <p>that SCSI block logical units, such as flexible disks, rigid disks, optical disks, etc. be attached</p> <p>to computers, and it provides the definition for their use.</p> <p>This standard defines a logical unit model for SCSI block logical units. Also defined are SCSI</p> <p>commands that apply to SCSI block logical units.</p> <p>The clause(s) of this standard pertaining to the SCSI block device class, implemented in</p> <p>conjunction with the applicable clauses of ISO/IEC 14776-311, fully specify the standard</p> <p>command set for SCSI block devices.</p> <p>The objectives of this standard are the following:</p> <p>a) permit an application client to communicate with a logical unit that declares itself to be a</p> <p>direct-access device, write-once device and optical memory device in the device type field</p> <p>of the INQUIRY command response data over an SCSI service delivery subsystem;</p> <p>b) define commands unique to the type of SCSI block devices;</p> <p>c) define commands to manage the operation of SCSI block devices;</p> <p>d) define the differences between types of SCSI block devices.</p> <p/> <p><b>Figure 1 ? SCSI standards ? General structure</b></p> <p>Figure 1 shows the general structure of SCSI standards. The figure does not imply a</p> <p>relationship such as a hierarchy, protocol stack, or system architecture. It indicates the</p> <p>applicability of a standard to the implementation of a given transport.</p>
