ISO/IEC 14776-342:2000

Information technology - Small Computer System Interface (SCSI) - Part 342: Controller Commands - 2 (SCC-2)

The SCSI command set is designed to provide efficient peer-to-peer operation of input/output devices (disks, tapes, printers, etc.) by an operating system, The SCSI command set assumes a command-response protocol. Action on SCSI commands shall not be deemed completed until a response is received. The response shall include a status that indicates the final disposition of the command. The SCSI command set provides multiple operating systems concurrent control over one or more input/output devices. However, the multiple operating systems should properly coordinate their actions or data corruption will result. This standard defines commands that assist with coordination between multiple operating systems. This standard defines a device model for SCSI storage arrays, commonly known as RAID devices. This standard defines the SCSI commands that may apply to SCSI storage arrays and the SCSI commands that are uniquely for SCSI storage arrays. It is intended to be the choice for new designs over the original SCSI-3 Controller Commands (SCC) standard. Several new high level service actions have been added to this standard that simplify configurations.

Overview

ISO/IEC 14776-342:2000 - Information technology - Small Computer System Interface - Part 342: Controller Commands‑2 (SCC‑2) defines a SCSI command set and device model for managing SCSI storage arrays (commonly known as RAID devices). Published as the SCC‑2 part of the SCSI family, this international standard specifies commands, addressing methods and high‑level service actions that support peer‑to‑peer I/O, multi‑OS coordination, and array management. It was intended as the preferred choice for new designs over the original SCSI‑3 Controller Commands (SCC).

Note: the standard includes a patent statement indicating that implementation may involve patent rights (IBM referenced in the published statement).

Key topics and technical requirements

• Command‑response protocol: Actions on SCSI commands are complete only after a response including a status is received; the standard assumes this model for reliable I/O.
• Device model for SCSI storage arrays: Defines objects such as component devices, peripheral devices, redundancy groups, spares, P_extents/Ps_extents and volume sets.
• Addressing methods: Multiple addressing schemes including direct, indirect and LUN structures for addressing logical units and components inside a storage array.
• Service actions and commands: Detailed service actions for management commands, including:
  • MAINTENANCE (IN / OUT) - inventory, attach/detach, exchange, device identification
  • REDUNDANCY GROUP (IN / OUT) - create/modify/delete groups, rebuild, recalculate, verify check data
  • VOLUME SET (IN / OUT) - assign/deassign LUN_V, control writes, create/modify/delete volume sets
  • SPARE (IN / OUT) - spare reporting and management
• Array operations & state management: Rebuild, recalculate, regenerate, verify; configuration methods (simple, basic, general); exception conditions and error handling.
• System layering and SACL: Defines Storage Array Conversion Layer (SACL), protocol conversion layers, and examples of layering variations for array architectures.

Practical applications and who uses it

• Storage array and RAID controller designers implementing SCSI command interfaces
• Firmware and HBA (Host Bus Adapter) developers integrating SCSI array management
• Operating system and SAN software engineers implementing multi‑OS coordination and LUN management
• System integrators, test and compliance engineers verifying SCSI array behavior (rebuilds, verify, redundancy)
• Enterprises and vendors building interoperable SCSI storage solutions that require standardized management commands

Related standards

• Part of the broader SCSI family; intended as successor/preference over the original SCSI‑3 Controller Commands (SCC). Implementers should consider other ISO/IEC SCSI parts for transport layers and device specifics.

Keywords: ISO/IEC 14776-342:2000, SCSI, SCC‑2, SCSI storage arrays, RAID, LUN addressing, MAINTENANCE (IN), REDUNDANCY GROUP, VOLUME SET, rebuild, verify, storage array management.
