This standard permits the SCSI automation/drive interface device type to communicate with application clients and defines the commands and data exchanged in such communications. This standard does not contain materi

Consensus i
7、s 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 objecti
8、ons 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
9、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 interpreta
10、tion 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 with
11、drawn 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 Natio

As of the date of publication of this standard, following calls for the identification of patents
15、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,

37、(This foreword is not part of American National Standard ANSI INCITS 441-2008.) This standard specifies the external behavior of a device server that defines itself as an automation/drive interface device in the DEVICE TYPE field of the standard INQUIRY data. This device type is known as an automati
38、on/drive interface device. Requests for interpretation, suggestions for improvement and addenda, or defect reports are welcome. They should be sent to the INCITS Secretariat, InterNational Committee for Information Technology Standards, Information Technology Institute, 1250 Eye Street, NW, Suite 20
39、0, Washington, DC 20005-3922. This standard was processed and approved for submittal to ANSI by the InterNa- tional Committee for Information Technology Standards (INCITS). Committee approval of the standard does not necessarily imply that all committee members voted for approval. At the time it app
