NAME

       sg_rep_zones - send SCSI REPORT ZONES command

SYNOPSIS

       sg_rep_zones   [--help]   [--hex]   [--maxlen=LEN]   [--raw]  [--readonly]  [--report=OPT]
       [--start=LBA] [--verbose] [--version] DEVICE

DESCRIPTION

       Sends a SCSI REPORT ZONES command to DEVICE and outputs the data returned. This command is
       found in the ZBC draft standard, revision 1c (zbc-r01c.pdf).

OPTIONS

       Arguments to long options are mandatory for short options as well.

       -h, --help
              output the usage message then exit.

       -H, --hex
              output  the response in hexadecimal to stdout. When used once the whole response is
              output in ASCII hexadecimal with a leading address (starting at 0)  on  each  line.
              When  used  twice  each  zone  descriptor  in  the response is output separately in
              hexadecimal. When used thrice the whole response is output in hexadecimal  with  no
              leading address (on each line).

       -m, --maxlen=LEN
              where  LEN  is  the  (maximum)  response length in bytes. It is placed in the cdb's
              "allocation length" field. If not given (or LEN is zero) then  8192  is  used.  The
              maximum allowed value of LEN is 1048576.

       -r, --raw
              output the SCSI response (i.e. the data-out buffer) in binary (to stdout).

       -R, --readonly
              open the DEVICE read-only (e.g. in Unix with the O_RDONLY flag).  The default is to
              open it read-write.

       -o, --report=OPT
              where OPT will become the contents of the REPORTING OPTION field in  the  cdb.  The
              default value is 0 which means report a list or all zones.  Some other values are 1
              for list full zones; 2 for list all open zones; 3 for list all empty zones;  4  for
              list  all  read only zones; 5 for list all offline zones; 6 for list all zones with
              the RESET bit set; and 7 for list all zones with the NON_SEQ bit set.

       -s, --start=LBA
              where LBA is at the start or within the first zone  to  be  reported.  The  default
              value  is  0.  If  LBA is not a zone start LBA then the preceding zone start LBA is
              used for reporting. Assumed to be in decimal unless prefixed with  '0x'  or  has  a
              trailing 'h' which indicate hexadecimal.

       -v, --verbose
              increase the level of verbosity, (i.e. debug output).

       -V, --version
              print the version string and then exit.

EXIT STATUS

       The exit status of sg_rep_zones is 0 when it is successful. Otherwise see the sg3_utils(8)
       man page.
