SG_REP_ZONES(8)			   SG3_UTILS		       SG_REP_ZONES(8)

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 2
       (zbc-r02.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.
