3、 without license from IHS -,-,- ANSI NCITS 318-1998 American National Standard for Information Technology SCSI Controller Commands-2 (SCC-2) Secretariat Information Technology Industry Council Approved June 9, 1998 American National Standards Institute, Inc. Abstract This standard defines commands f
4、or SCSI storage array devices; commonly known as RAID devices. This standard is principally intended to be used in conjunction with, not as an alternate to, any of the SCSI command standards and the SCSI-3 Architecture Model Standard. The commands described in this standard facilitate the control an
5、d configuration of SCSI storage arrays and thus provide a common command specification for both system integrators and suppliers of SCSI storage array devices.

7、per. 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 v
8、iews 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, purch
9、asing, 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 iss
10、ue 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
11、 revised or withdrawn at any time.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 th

However, nei- ther 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 identifica

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
16、(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 ob- tain such a license. Details may be obtained from the publisher. No further patent search is con- ducted by the developer or
17、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.
