sg_zone [--all] [--close] [--count=ZC] [--finish] [--help] [--open] [--sequentialize] [--verbose] [--version] [--zone=ID] DEVICE
Sends a SCSI OPEN ZONE, CLOSE ZONE, FINISH ZONE or SEQUENTIALIZE ZONE command to the DEVICE. All but the last are found in the soon to be released ZBC standard (close to draft ZBC BSR INCITS 536 revision 05). The SEQUENTIALIZE ZONE command was added in zbc2r01b.
One and only one of the --open, --close, --finish and --sequentialize options can be chosen.
Arguments to long options are mandatory for short options as well.
- -a, --all
sets the ALL field in the cdb.
- -c, --close
causes the CLOSE ZONE command to be sent to the DEVICE.
- -C, --count=ZC
ZC is placed in the Zone Count field in the cdb of all four commands supported by this utility. ZC should be a value from 0 to 65535 (0xffff) inclusive.
- -f, --finish
causes the FINISH ZONE command to be sent to the DEVICE.
- -h, --help
output the usage message then exit.
- -o, --open
causes the OPEN ZONE command to be sent to the DEVICE.
- -S, --sequentialize
causes the SEQUENTIALIZE ZONE command to be sent to the DEVICE.
- -v, --verbose
increase the level of verbosity, (i.e. debug output).
- -V, --version
print the version string and then exit.
- -z, --zone=ID
where ID is placed in the cdb's ZONE ID field. A zone id is a zone start logical block address (LBA). The default value is 0. ID is assumed to be in decimal unless prefixed with '0x' or has a trailing 'h' which indicate hexadecimal.
The exit status of sg_zone is 0 when it is successful. Otherwise see the sg3_utils(8) man page.
