iscsictl – iSCSI initiator management utility



iscsictl -A -p portal -t target [-u user -s secret] [-w timeout] [-r] [-e on | off]
iscsictl -A -d discovery-host [-u user -s secret] [-r] [-e on | off]
iscsictl -A -a [-c path]
iscsictl -A -n nickname [-c path]
iscsictl -M -i session-id [-p portal] [-t target] [-u user] [-s secret] [-e on | off]
iscsictl -M -i session-id [-n nickname [-c path]]
iscsictl -R [-p portal] [-t target]
iscsictl -R -a
iscsictl -R -n nickname [-c path]
iscsictl -L [-v] [-w timeout]


The iscsictl utility is used to configure the iSCSI initiator.

The following options are available:
  Generate output via libxo(3) in a selection of different human and machine readable formats. See xo_parse_args(3) for details on command line arguments.
  Add session.
  Modify session.
  Remove session.
  List sessions.
  When adding, add all sessions defined in the configuration file. When removing, remove all currently established sessions.
  Path to the configuration file. The default is /etc/iscsi.conf.
  Target host name or address used for SendTargets discovery. When used, it will add a temporary discovery session. After discovery is done, sessions will be added for each discovered target, and the temporary discovery session will be removed.
  Enable or disable the session. This is ignored for discovery sessions, but gets passed down to normal sessions they add.
  Session ID, as displayed by iscsictl -v.
  The "nickname" of session defined in the configuration file.
  Target portal - host name or address - for statically defined targets.
  Use iSER (iSCSI over RDMA) instead of plain iSCSI over TCP/IP.
  CHAP secret.
  Target name.
  CHAP login.
  Verbose mode.
  Instead of returning immediately, wait up to timeout seconds until all configured sessions are successfully established.

Certain parameters are necessary when adding a session. One can specify these either via command line (using the -t, -p, -u, and -s options), or configuration file (using the -a or -n options). Some functionality - for example mutual CHAP - is available only via configuration file.

Since connecting to the target is performed in background, non-zero exit status does not mean that the session was successfully established. Use either Fl to check the connection status, or the -w flag to wait for session establishment.

Note that in order for the iSCSI initiator to be able to connect to a target, the iscsid(8) daemon must be running.

Also note that FreeBSD currently supports two different initiators: the old one, iscsi_initiator(4), with its control utility iscontrol(8), and the new one, iscsi(4), with iscsictl and iscsid(8). The only thing the two have in common is the configuration file, iscsi.conf(5).

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

Perform discovery on, and add disabled sessions for each discovered target; use -M to connect them:


Disconnect all iSCSI sessions:



libxo(3), xo_parse_args(3), iscsi(4), iscsi.conf(5), iscsid(8)


The iscsictl command appeared in FreeBSD 10.0 .


The iscsictl utility was developed by Edward Tomasz Napierala <Mt trasz@FreeBSD.org> under sponsorship from the FreeBSD Foundation.

As soon as we started programming, we found to our surprise that it wasn't as easy to get programs right as we had thought. Debugging had to be discovered. I can remember the exact instant when I realized that a large part of my life from then on was going to be spent in finding mistakes in my own programs.
