NAME

       istgtcontrol - istgt iSCSI target command utility

SYNOPSIS

       istgtcontrol [options] <command> [<file>]

DESCRIPTION

       istgtcontrol  is  a command and control utility for istgt(1).  It can be used to query and
       change the status of a local or remote istgt instance.

       istgtcontrol supports the commands denoted below to interact with the istgt  instance.  By
       default  it  connects  and  authenticates  to  the  iSCSI  target  portal specified in the
       istgtcontrol.conf configuration file and uses CHAP  credentials  denoted  there,  if  any.
       Both can be overridden by using the respecitve command line arguments.

COMMANDS

       istgtcontrol understands the following commands which can be forwarded to istgt:

       noop   Do  not  actually  do anything, but test responsiveness of the portal and test CHAP
              credentials only.

       version
              Retrieve the istgt version number providing the iSCSI portal istgtcontrol connected
              to.

       list   List all, or the specified targets only, which shared by the portal.

       load   Load  a new media to the specified unit. This command issues the same command as if
              a drive tray had been closed on a SCSI device.

       unload Unload a media from the specified unit. This command issues the same command as  if
              the drive tray had been opened from a SCSI device.

       change file
              Change  the  loaded media by the specified unit. This command is equivalent as if a
              new media (for example a DVD-ROM or tape cartridge) had been inserted in  the  SCSI
              drive. The "file" argument is interpreted as filename to be loaded.

       reset  Reset the specified LUN of the portal.

       info   Display all connections of the portal

OPTIONS

       -c config
              Use specified file as configuration file instead of the default file.

       -h host
              Override  the target portal by the specified host name or IP address. This defaults
              to "localhost" if no other host was specified in the configuration file.

       -p port
              Override the target portal port by the specified  port  number.  This  defaults  to
              "3261" if no other port was specified in the configuration file.

       -t target
              Specifies  the target IQN which should be affected by the command given.  There may
              be a default given in the configuration file. The keyword "all" is accepted by some
              commands and matches all exported volumes.

       -l lun Specifies  the  target  LUN  which  should  be affected by the command given.  This
              defaults to "0" unless another default was provided in the configuration file.

       -f flags
              Specifies flags passed to the portal when loading a new  media.  This  defaults  to
              "ro". Supported flags are: "ro", "rw", "extend" and "dynamic".

       -s size
              Specifies  the  size  of  the  meda to be loaded. The default is to auto-detect the
              media size.

       -q     Quiet mode, supress non-critical outputs.

       -v     Verbose mode, gives more output during operations.

       -A method
              Sets the preferred authentication  method  for  logging  in  to  the  portal.  This
              overrides  any  method  specified  in the configuration file. Supported methods are
              either CHAP/Mutual or CHAP/Auto.

       -U user
              Sets the user to authenticate on the portal. This overrides any username  specified
              in the configuration file.

       -S secret
              Set  the  secret  used  to  authenticate  on  the portal. This overrides any secret
              specified in the configuration file.

       -M muser
              Set the mutual authentication user.  This  overrides  any  user  specified  in  the
              configuration file.

       -R msecret
              Set  the  mutual  authentication secret. This overrides any secret specified in the
              configuration file.
