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
