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.
