                         [--version] DEVICE
  where:
    --address=LA_L | -a LA_L    same as --log=LA_L option below
    --ck_cond | -C          set ck_cond field in pass-through (def: 0)
    --count=CO | -c CO      count of page numbers to fetch (def: 1)
    --dma | -d              Use READ LOG DMA EXT (def: READ LOG EXT)
    --help | -h             output this usage message
    --hex | -H              output response in hex bytes, -HH yields hex
                            words + ASCII (def), -HHH hex words only
    --len=CDB_LEN | -l CDB_LEN    cdb length: 12, 16 or 32 bytes (def: 16)
    --log=LA_L | -L LA_L    Log address, log address range or list of ...
                            See below for syntax
    --page=PN|-p PN         Log page number within address (def: 0)
    --ppt=PPT|-P PPT        pages per transfer (def: 64)
    --readonly | -r         open DEVICE read-only (def: read-write)
    --smart | -s            send the ATA SMART READ LOG command instead
    --verbose | -v          increase verbosity
                            recommended if DEVICE is ATA disk
    --version | -V          print version string and exit

Sends an ATA READ LOG (DMA) EXT or a SMART READ LOG command via a SAT
pass-through to fetch one or more General Purpose (GP) or SMART log pages.
Each page is accessed via a log address (LA) and then a page number
within that address. Multiple log addresses can be given in the LA_L
argument to the --address= and --log= options. It may contain a comma
separated list with each element either being a single LA or a range with
this format: 'lo:hi'. LA_R syntax summary: lo:hi,lo2:hi2,lo3:hi3,...
