       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.
