Consensus requires that allviews and objections be considered, and that a concerted effort be madetowards their resolution.The use of American Nat

36、An SCSIcommand set is defined for managing various non-SCSI elements contained withinthe enclosure.This standard was developed by Technical Committee X3T10 of Accredited Stan-dards Committee X3 during 1996. The standards approval process started in 1996.This standard includes two annexes. Annex A is
37、 normative and considered part ofthis standard. Annex B is for information only.Requests for interpretation, suggestions for improvement or addenda, or defect re-ports are welcome. They should be sent to the National Committee for InformationTechnology Standards (NCITS), ITI, 1250 Eye Street, NW, Su
38、ite 200, Washington,DC 20005.This standard was processed and approved for submittal to ANSI by NCITS. Com-mittee approval of the standard does not necessarily imply that all committee mem-bers voted for its approval. At the time it approved this standard, NCITS had thefollowing members:Richard Gibso
