ISO/IEC 14776-342:2000

This International Standard defines the command set extensions for SCSI storage array devices; commonly known as RAID devices. This standard is principally intended to be used in conjunction with, not as an alternate to, any of the SCSI command standards nor to the SCSI-3 Architecture Model (ISO/IEC 14776-411) standard. This international standard is intended as an alternate to the SCSI-3 Controller Command (ISO/IEC 14776-341) standard. The resulting commands facilitate the control and configuration of SCSI storage arrays and thus provide a common command specification for both system integrators and suppliers of SCSI storage array devices.

This international standard contains all the information defined in SCSI-3 Controller Command (ISO/IEC 14776-341) standard. In addition this international standard specifies new commands and an expanded model clause.

The clause(s) of this standard pertaining to the SCSI storage array device class, implemented in conjunction with the applicable clauses within any of the SCSI command standards, shall specify the standard command set available for SCSI storage arrays.

The objective of the SCSI Controller Commands is to provide the following:

a) Transfer commands unique to SCSI Controller Command devices;

b) Control commands to manage the operation of an SCSI Controller Command device;

c) Optional device mapping and pass-through support.
