Description / Abstract:
This standard defines a Reduced Block Command set for logical block devices. The Reduced Block Commands along with the required SPC-2 commands and their restrictions described in this standard, fully specify the complete command set for RBC logical block devices.
Purpose
The purpose of this document is to provide a command set of reduced requirements and options from SCSI Block Commands (ANSI NCITS 306-1998) for block devices. The reduced command set is intended to more closely match the functionality required for simple block logical units. The specified commands place no restrictions on device performance. The initial focus of this command set was rigid disks and removable media devices attached to Serial Bus and utilizing SBP-2 (ANSI NCITS 325- 1998) for command and control.
