sg_zone — send SCSI OPEN, CLOSE or FINISH ZONE command


sg_zone [--all] [--close] [--finish] [--help] [--open] [--verbose] [--version] [--zone=ID] DEVICE


Sends a SCSI OPEN ZONE, CLOSE ZONE or FINISH ZONE command to the DEVICE. These commands are found in the ZBC draft standard revision 4c (zbc-r04c.pdf).

One and only one of the --open, --close and --finish 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.

-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.

-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.

Exit Status

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