`Abstract
`This standard defines the device model for all SCSI devices. This standard defines the SCSI com-
`mands that are basic to every device model and the SCSI commands that may apply to any
`device model.
`The processor device model is defined in this standard. Some target SCSI devices may require a
`host implementation of the processor device model to support the Asynchronous Event Reporting
`capability defined in the SCSI-3 Architecture Model.

`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 judgment 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 toward 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 an interpretation of 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`withdrawn at any time.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, following calls for the identification of patents that may be required for the implementation of
`the standard, notice of one or more such claims has been received. By publication of this standard, no position is taken
`with respect to the validity of this claim or of any rights in connection therewith. The known patent holder(s) has (have),
`however, filed a statement of willingness to grant a license under these rights on reasonable and nondiscriminatory terms
`and conditions to applicants desiring to obtain such a license. Details may be obtained from the publisher. No further
`patent search is conducted by the developer or publisher in respect to any standard it processes. No representation is
`made or implied that this is the only license that may be required to avoid infringement in the use of this standard.

`Foreword (This foreword is not part of American National Standard X3.301-1997.)
`The SCSI command set is designed to provide efficient peer-to-peer opera-
`tion of SCSI devices (disks, tapes, printers, etc.) by an operating system. The
`SCSI command set assumes an underlying command-response protocol.
`The SCSI command set provides multiple operating systems concurrent
`control over one or more SCSI devices. However, proper coordination of
`activities between the multiple operating systems is critical to avoid data
`corruption. Commands that assist with coordination between multiple oper-
`ating systems are described in this standard. However, details of the coor-
`dination are beyond the scope of the SCSI command set.
`This standard defines the device model for all SCSI devices. This standard
`defines the SCSI commands that are basic to every device model and the
`SCSI commands that may apply to any device model.
`The processor device model is defined in this standard. Some target SCSI
`devices may require a host implementation of the processor device model
`to support the Asynchronous Event Reporting capability defined in the
`SCSI-3 Architecture Model. Thus, the SCSI processor device commands
`are defined in this standard.
`With any technical document there may arise questions of interpretation as
`new products are implemented. The NCITS Committee has established
`procedures to issue technical opinions concerning the standards devel-
`oped by the NCITS organization. These procedures may result in SCSI
`Technical Information Bulletins being published by NCITS.
`These Bulletins, while reflecting the opinion of the Technical Committee
`that developed the standard, are intended solely as supplementary infor-
`mation to other users of the standard. This standard, ANSI X3.301-1997,
`as approved through the publication and voting procedures of the
`American National Standards Institute, is not altered by these bulletins.
`Any subsequent revision to this standard may or may not reflect the con-
`tents of these Technical Information Bulletins.
`Current NCITS practice is to make Technical Information Bulletins avail-
`able through:
`Telephone: 303-792-2181 or
`Global Engineering
`800-854-7179
`15 Inverness Way East
`Facsimile: 303-792-2192
`Englewood, CO 80112-5704
`Requests for interpretation, suggestions for improvement and addenda, or
`defect reports are welcome. They should be sent to the NCITS Secretariat,
`Information Technology Industry Council, ITI, 1250 Eye Street, NW, Suite
`200, Washington, DC 20005-3922.
`This standard was processed and approved for submittal to ANSI by the
`National Committee for Information Technology Standards (NCITS).
`Committee approval of the standard does not necessarily imply that all
`committee members voted for approval. At the time it approved this stan-
`dard, NCITS had the following members:
