2、Industry CouncilApproved May 12, 2008American National Standards Institute, Inc.AbstractThis standard specifies the device model and functional requirements for the SCSI automation/driveinterface device type. This standard permits the SCSI automation/drive interface device type tocommunicate with ap

3、plication clients and defines the commands and data exchanged in suchcommunications.This standard does not contain material related to the service delivery subsystem that is used to transportthe commands, command parameter data, command response data, and status specified in this standard.Approval o

4、f an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Consensus is established when, in the judgement of the ANSI Board ofStandards Review, substantial agreement has been reache

5、d by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that allviews and objections be considered, and that a concerted effort be madetowards their resolution.The use of American National Standard

6、s is completely voluntary; theirexistence does not in any respect preclude anyone, whether he has approvedthe standards or not, from manufacturing, marketing, purchasing, or usingproducts, processes, or procedures not conforming to the standards.The American National Standards Institute does not dev

7、elop standards andwill in no circumstances give an interpretation of any American NationalStandard. Moreover, no person shall have the right or authority to issue aninterpretation of an American National Standard in the name of the AmericanNational Standards Institute. Requests for interpretations s

8、hould beaddressed to the secretariat or sponsor whose name appears on the titlepage of this standard.CAUTION NOTICE: This American National Standard may be revised orwithdrawn at any time. The procedures of the American National StandardsInstitute require that action be taken periodically to reaffir

However, nei-ther the developers nor the publisher have undertaken a patent search in order to iden

12、tify which, ifany, patents may apply to this standard. As of the date of publication of this standard, followingcalls 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

13、 positionis taken with respect to the validity of this claim or of any rights in connection therewith. The knownpatent holder(s) has (have), however, filed a statement of willingness to grant a license underthese rights on reasonable and nondiscriminatory terms and conditions to applicants desiring

14、to ob-tain such a license. Details may be obtained from the publisher. No further patent search is con-ducted by the developer or publisher in respect to any standard it processes. No representation ismade or implied that this is the only license that may be required to avoid infringement in the use
