NAME

     ctld -- CAM Target Layer / iSCSI target daemon

SYNOPSIS

     ctld [-d] [-f config-file]

DESCRIPTION

     The ctld daemon is responsible for managing the CAM Target Layer configuration, accepting incoming iSCSI connections, performing authentica-
     tion and passing connections to the kernel part of the native iSCSI target.

     Upon startup, the ctld daemon parses the configuration file and exits, if it encounters any errors.  Then it compares the configuration with
     the kernel list of LUNs managed by previously running ctld instances, removes LUNs no longer existing in the configuration file, and creates
     new LUNs as necessary.  After that it listens for the incoming iSCSI connections, performs authentication, and, if successful, passes the
     connections to the kernel part of CTL iSCSI target, which handles it from that point.

     When it receives a SIGHUP signal, the ctld reloads its configuration and applies the changes to the kernel.  Changes are applied in a way
     that avoids unnecessary disruptions; for example removing one LUN does not affect other LUNs.

     When exiting gracefully, the ctld daemon removes LUNs it managed and forcibly disconnects all the clients.  Otherwise - for example, when
     killed with SIGKILL - LUNs stay configured and clients remain connected.

     To perform administrative actions that apply to already connected sessions, such as forcing termination, use ctladm(8).

     The following options are available:

     -f config-file
		 Specifies the name of the configuration file.	The default is /etc/ctl.conf.

     -d 	 Debug mode.  The server sends verbose debug output to standard error, and does not put itself in the background.  The server will
		 also not fork and will exit after processing one connection.  This option is only intended for debugging the target.

FILES

     /etc/ctl.conf	The configuration file for ctld.  The file format and configuration options are described in ctl.conf(5).
     /var/run/ctld.pid	The default location of the ctld PID file.

EXIT STATUS

     The ctld utility exits 0 on success, and >0 if an error occurs.
