istgtcontrol

istgtcontrol(1) 					      General Commands Manual						   istgtcontrol(1)

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 overrid-
       den 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 car-
	      tridge) 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 configu-
	      ration 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.

       -H     Display a brief usage summary and exit.

       -V     Display the istgtcontrol version number and exit.

       FILES
       /etc/istgt/istgtcontrol.conf
	      Configuration file
