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
