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.
