Preface

Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).

Scope

This part of ISO/IEC 14776 defines the command set extensions for operation of SCSI medium changer devices and command set extensions that allow medium changer functions in other types of SCSI devices.

This SCSI-3 Medium Changer Commands standard

• permits an application client to communicate with a logical unit that declares itself to be a medium changer device in the DEVICE TYPE field of the INQUIRY command response data over a SCSI service delivery subsystem,
• permits an application client to access the medium changer functions in a logical unit that sets the MCHNGR bit in INQUIRY command response data,
• defines commands to manage the operation of SCSI medium changer devices.
