                               [--data-size=<size> | -z <size>]
                               [--ref-tag=<reftag> | -r <reftag>]
                               [--data=<data-file> | -d <data-file>]

                               [--app-tag-mask=<appmask> | -m <appmask>]
                               [--app-tag=<apptag> | -a <apptag>]
                               [--limited-retry | -l]

DESCRIPTION

       The Compare command reads the logical blocks specified by the command from the medium and compares the
       data read to a comparison data buffer transferred as part of the command. If the data read from the
       controller and the comparison data buffer are equivalent with no miscompares, then the command completes
       successfully. If there is any miscompare, the command completes with an error of Compare Failure. If
       metadata is provided, then a comparison is also performed for the metadata.

OPTIONS
