NAME¶

sg_zone - send a SCSI ZONE modifying command

SYNOPSIS¶

sg_zone [--all] [--close] [--count=ZC] [--element=EID] [--finish] [--help] [--open] [--remove] [--sequentialize] [--verbose] [--version] [--zone=ID] DEVICE

DESCRIPTION¶

Sends a SCSI OPEN ZONE, CLOSE ZONE, FINISH ZONE, REMOVE ELEMENT AND MODIFY ZONES or SEQUENTIALIZE ZONE command to the DEVICE. All but the last two are found in the ZBC standard (INCITS 536-2016). The REMOVE ELEMENT AND MODIFY ZONES command was added in zbc2r07 while the SEQUENTIALIZE ZONE command was added in zbc2r01b.

One and only one of the --open, --close, --finish, --remove and --sequentialize options can be chosen.

OPTIONS¶

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.
-e, --element=EID: where EID is an element identifier which is a 32 bit unsigned integer starting at one. This field is used by the REMOVE ELEMENT AND MODIFY ZONES command and its default value is zero (which is invalid). So the user needs to supply a valid element identifier when --remove is used.
-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.
-r, --remove: causes the REMOVE ELEMENT AND MODIFY ZONES command to be sent to the DEVICE. In practice, --element=EID needs to be also given.
-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.

EXIT STATUS¶

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