.Sh DESCRIPTION
The
.Nm
utility is used to configure the iSCSI initiator.
.Pp
The following options are available:
.Bl -tag -width ".Fl A"
.It Fl A
Add session.
.It Fl M
Modify session.
.It Fl R
Remove session.
.It Fl L
List sessions.
.It Fl a
When adding, add all sessions defined in the configuration file.
When removing, remove all currently established sessions.
.It Fl c
Path to the configuration file.
The default is
.Pa /etc/iscsi.conf .
.It Fl d
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.
.It Fl i
Session ID, as displayed by
.Nm
.Fl v .
.It Fl n
The "nickname" of session defined in the configuration file.
.It Fl p
Target portal - host name or address - for statically defined targets.
.It Fl s
CHAP secret.
.It Fl t
Target name.
.It Fl u
CHAP login.
.It Fl v
Verbose mode.
.It Fl w
Instead of returning immediately, wait up to
.Ar timeout
seconds until all configured sessions are successfully established.
.El
.Pp
Certain parameters are necessary when adding a session.
One can specify these either via command line (using the
.Fl t ,
.Fl p ,
.Fl u ,
and
.Fl s
options), or configuration file (using the
.Fl a
or
.Fl n
options).
Some functionality - for example mutual CHAP - is available only
via configuration file.
.Pp
Since connecting to the target is performed in background, non-zero
exit status does not mean that the session was successfully established.
Use either
.Nm Fl L
to check the connection status, or the
.Fl w
flag to wait for session establishment.
.Pp
Note that in order for the iSCSI initiator to be able to connect to a target,
the
.Xr iscsid 8
daemon must be running.
.Pp
Also note that
.Fx
currently supports two different initiators: the old one,
.Xr iscsi_initiator 4 ,
with its control utility
.Xr iscontrol 8 ,
and the new one,
.Xr iscsi 4 ,
with
.Nm
and
.Xr iscsid 8 .
The only thing the two have in common is the configuration file,
.Xr iscsi.conf 5 .
.Sh FILES
.Bl -tag -width ".Pa /etc/iscsi.conf" -compact
.It Pa /etc/iscsi.conf
iSCSI initiator configuration file.
.El
.Sh EXIT STATUS
The
.Nm
utility exits 0 on success, and >0 if an error occurs.
.Sh EXAMPLES
Attach to target iqn.2012-06.com.example:target0, served by 192.168.1.1:
.Dl Nm Fl A Fl t Ar iqn.2012-06.com.example:target0 Fl p Ar 192.168.1.1
.Pp
Disconnect all iSCSI sessions:
.Dl Nm Fl Ra
.Sh SEE ALSO
.Xr iscsi 4 ,
.Xr iscsi.conf 5 ,
.Xr iscsid 8
.Sh HISTORY
The
.Nm
command appeared in
.Fx 10.0 .
.Sh AUTHORS
The
.Nm
utility was developed by
.An Edward Tomasz Napierala Aq Mt trasz@FreeBSD.org
under sponsorship from the FreeBSD Foundation.
