  where:
    --all|-a        output all pages listed in the supported pages VPD
                    page
    --descriptors|-d    display standard inquiry version descriptors
    --enumerate|-e    enumerate known VPD pages names (ignore DEVICE),
                      can be used with --page=num to search
    --examine|-E    starting at 0x80 scan pages code to 0xff
    --force|-f      skip VPD page 0 (supported VPD pages) checking
    --help|-h       output this usage message then exit
    --hex|-H        output page in ASCII hexadecimal
    --ident|-i      output device identification VPD page, twice for
                    short logical unit designator (equiv: '-qp di_lu')
    --inhex=FN|-I FN    read ASCII hex from file FN instead of DEVICE;
                        if used with --raw then read binary from FN
    --json[=JO]|-j[=JO]    output in JSON instead of plain text
                           Use --json=? for JSON help
    --js-file=JFN|-J JFN    JFN is a filename to which JSON output is
                            written (def: stdout); truncates then writes
    --long|-l       perform extra decoding
    --maxlen=LEN|-m LEN    max response length (allocation length in cdb)
                           (def: 0 -> 252 bytes)
    --page=PG|-p PG    fetch VPD page where PG is an acronym, or a decimal
                       number unless hex indicator is given (e.g. '0x83');
                       can also take PG,VP as an operand
    --quiet|-q      suppress some decoding and error output
    --raw|-r        output page in binary; if --inhex=FN is also
                    given, FN is in binary (else FN is in hex)
    --sinq_inraw=RFN|-Q RFN    read raw (binary) standard INQUIRY
                               response from the RFN filename
    --vendor=VP|-M VP    vendor/product abbreviation [or number]
    --verbose|-v    increase verbosity
    --version|-V    print version string and exit

Fetch Vital Product Data (VPD) page using SCSI INQUIRY or decodes VPD
page response held in file FN. To list available pages use '-e'. Also
'-p -1' or '-p sinq' yields the standard INQUIRY response.
