This file contains the operation code definitions for all commands defined by the SCSI specifications. The commands are listed in three formats: 1) All commands are listed in alphabetical order. This list is the live enumeration for all of the command constants. 2) The commands are listed in ascending numerical order. 3) The commands are grouped by Peripheral Device Type. In the command listings by Peripheral Device Type, there will be a comment following each command. This comment indentifies the section of the related specification where the commands is defined and the requirement type of the command, Mandatory or Optional. If a specification redefines an optional command from SPC as mandatory, the command will be relisted in the Peripheral Device Type command list with the mandatory tag next to it. All commands that are listed in SPC as Device Type Specifc will be relisted as a comment in all specifications lists that support that command with the appropriate Mandatory or Optional tag for that specification. The section number and the requirement type of the command are based on the version of the specification listed in the header comment for the Peripheral Device Type. This data is provided for informational purposes only. The specification document and version that the device adheres to as indicated by the data returned in response to the INQUIRY command should be used as the authorative source for supported and required behavior of the device. The SPC set is listed before all other Peripheral Device Type commands as this is the base document from which all of the other documents are derived. The Peripheral Device Types and associated command sets as defined by SPC-2, section 7.4.1 are as follows: Peripheral Device Type Associated Command Specification ------------------------------------ ----------------------------------- 0x00 Direct Access Device SBC - SCSI-3 Block Commands 0x01 Sequential Access Device SSC - SCSI-3 Stream Commands 0x02 Printer Device SSC - SCSI-3 Stream Commands 0x03 Processor Device SPC - SCSI Primary Commands-2 0x04 Write Once Device SBC - SCSI-3 Block Commands 0x05 CD-ROM Device MMC - SCSI Multimedia Commands-2 0x06 Scanner Device SGC - SCSI-3 Graphics Commands 0x07 Optical Memory Device SBC - SCSI-3 Block Commands 0x08 Medium Changer Device SMC - SCSI-3 Medium Changer Cmds 0x09 Communications Device SSC - SCSI-3 Stream Commands 0x0A - 0x0B Graphic Arts Prepress Dev ASC IT8 0x0C Storage Array Controller Device SCC-2 - SCSI Controller Commands-2 0x0D Enclosure Services SES - SCSI-3 Enclosure Services 0x0E Simplified Direct Access Device RBC - SCSI Reduced Block Commands 0x0F Optical Card Reader/Writer Device OCRW - SCSI Specification for Optical Card Reader/Writer 0x10 Reserved No command specification 0x11 Object-Based Storage Device OSD - SCSI Object Based Storage Device Commands 0x12 - 0x14 Reserved No command specification 0x15 Multimedia Media Access Engine RMC - Reduced Multimedia Commands 0x16 - 0x1E Reserved No command specification 0x1F Unknown or No Device No command specification

enum(anonymous)

Commands defined by the T10:1363-D SCSI Multimedia Commands-3 (MMC-3) specification. The definitions and section numbers are based on section 6.1 of the revision 01, March 03, 2000 version of the specification. NOTE: The comments following each command may not be accurate. These are not from the MMC-3 specification, but have been derived from the SCSI-2 and original MMC specifications. Unlike the other SCSI command specifications, MMC-2 and MMC-3 do not provide a command requirement type and therefore does not relist the SPC commands with these requirements as they apply to MMC devices. The MMC-2 and MMC-3 specifications also refer back to the SBC specification which seems invalid since MMC devices do not represent a Peripheral Device Type defined by SBC. It is assumed that the SBC references refer to the Peripheral Device Type 0x00 - Direct Access Commands definitions from that specification.
