`
`Abstract
`This standard specifies the functional requirements for the SCSI-3 Block Command set (SBC). SBC per-
`mits SCSI block logical units such as flexible disks, rigid disks, optical disks, etc., to attach to computers
`and provides the definition for their use.

`
`American
`National
`Standard
`
`Approval of an American National Standard requires review by ANSI that the
`requirements for due process, consensus, and other criteria for approval
`have been met by the standards developer.
`Consensus is established when, in the judgement of the ANSI Board of
`Standards Review, substantial agreement has been reached by directly and
`materially affected interests. Substantial agreement means much more than
`a simple majority, but not necessarily unanimity. Consensus requires that all
`views and objections be considered, and that a concerted effort be made
`towards their resolution.
`The use of American National Standards is completely voluntary; their
`existence does not in any respect preclude anyone, whether he has approved
`the standards or not, from manufacturing, marketing, purchasing, or using
`products, processes, or procedures not conforming to the standards.
`The American National Standards Institute does not develop standards and
`will in no circumstances give interpretation on any American National
`Standard. Moreover, no person shall have the right or authority to issue an
`interpretation of an American National Standard in the name of the American
`National Standards
`Institute. Requests
`for
`interpretations should be
`addressed to the secretariat or sponsor whose name appears on the title
`page of this standard.
`
`CAUTION NOTICE: This American National Standard may be revised or
`withdrawn at any time. The procedures of the American National Standards
`Institute require that action be taken periodically to reaffirm, revise, or
`withdraw this standard. Purchasers of American National Standards may
`receive current information on all standards by calling or writing the American
`National Standards Institute.
`
`CAUTION:
` The developers of this standard have requested that holders of patents that may be
`required for the implementation of the standard disclose such patents to the publisher. However,
`neither the developers nor the publisher have undertaken a patent search in order to identify
`which, if any, patents may apply to this standard.
`As of the date of publication of this standard and following calls for the identification of patents
`that may be required for the implementation of the standard, no such claims have been made. No
`further patent search is conducted by the developer or publisher in respect to any standard it pro-
`cesses. No representation is made or implied that licenses are not required to avoid infringement
`in the use of this standard.

`Foreword (This foreword is not part of American National Standard NCITS 306-1998.)
`This SCSI command set is designed to provide efficient peer-to-peer operation of in-
`put/output logical units by an operating system using block transfers. The SCSI com-
`mand set assumes an underlying command-response protocol.
`This SCSI command set provides multiple operating systems concurrent control over
`one or more input/output logical units. However, the multiple operating systems are
`assumed to properly coordinate their actions to prevent data corruption. This SCSI
`standard provides commands that assist with coordination between multiple operat-
`ing systems. However, details of the coordination are beyond the scope of the SCSI
`command set.
`This standard def
