76.Sh DESCRIPTION
77The
78.Nm
79utility is used to configure the iSCSI initiator.
80.Pp
81The following options are available:
82.Bl -tag -width ".Fl A"
83.It Fl A
84Add session.
85.It Fl M
86Modify session.
87.It Fl R
88Remove session.
89.It Fl L
90List sessions.
91.It Fl a
92When adding, add all sessions defined in the configuration file.
93When removing, remove all currently established sessions.
94.It Fl c
95Path to the configuration file.
96The default is
97.Pa /etc/iscsi.conf .
98.It Fl d
99Target host name or address used for SendTargets discovery.
100When used, it will add a temporary discovery session.
101After discovery is done, sessions will be added for each discovered target,
102and the temporary discovery session will be removed.
103.It Fl i
104Session ID, as displayed by
105.Nm
106.Fl v .
107.It Fl n
108The "nickname" of session defined in the configuration file.
109.It Fl p
110Target portal - host name or address - for statically defined targets.
111.It Fl s
112CHAP secret.
113.It Fl t
114Target name.
115.It Fl u
116CHAP login.
117.It Fl v
118Verbose mode.
119.It Fl w
120Instead of returning immediately, wait up to
121.Ar timeout
122seconds until all configured sessions are successfully established.
123.El
124.Pp
125Certain parameters are necessary when adding a session.
126One can specify these either via command line (using the
127.Fl t ,
128.Fl p ,
129.Fl u ,
130and
131.Fl s
132options), or configuration file (using the
133.Fl a
134or
135.Fl n
136options).
137Some functionality - for example mutual CHAP - is available only
138via configuration file.
139.Pp
140Since connecting to the target is performed in background, non-zero
141exit status does not mean that the session was successfully established.
142Use either
143.Nm Fl L
144to check the connection status, or the
145.Fl w
146flag to wait for session establishment.
147.Pp
148Note that in order for the iSCSI initiator to be able to connect to a target,
149the
150.Xr iscsid 8
151daemon must be running.
152.Pp
153Also note that
154.Fx
155currently supports two different initiators: the old one,
156.Xr iscsi_initiator 4 ,
157with its control utility
158.Xr iscontrol 8 ,
159and the new one,
160.Xr iscsi 4 ,
161with
162.Nm
163and
164.Xr iscsid 8 .
165The only thing the two have in common is the configuration file,
166.Xr iscsi.conf 5 .
167.Sh FILES
168.Bl -tag -width ".Pa /etc/iscsi.conf" -compact
169.It Pa /etc/iscsi.conf
170iSCSI initiator configuration file.
171.El
172.Sh EXIT STATUS
173The
174.Nm
175utility exits 0 on success, and >0 if an error occurs.
176.Sh EXAMPLES
