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 and configuration of SCSI storage arrays and thus provide a common
command specification for both system integrators and suppliers of SCSI storage array devices.

CAUTION: The developers of this standard have requested that holder's 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
claimsh asb eenr eceived.
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 has, 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 obtaine.d from the publisher
