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 -libxo
84Generate output via
85.Xr libxo 3
86in a selection of different human and machine readable formats.
87See
88.Xr xo_parse_args 3
89for details on command line arguments.
90.It Fl A
91Add session.
92.It Fl M
93Modify session.
94.It Fl R
95Remove session.
96.It Fl L
97List sessions.
98.It Fl a
99When adding, add all sessions defined in the configuration file.
100When removing, remove all currently established sessions.
101.It Fl c
102Path to the configuration file.
103The default is
104.Pa /etc/iscsi.conf .
105.It Fl d
106Target host name or address used for SendTargets discovery.
107When used, it will add a temporary discovery session.
108After discovery is done, sessions will be added for each discovered target,
109and the temporary discovery session will be removed.
110.It Fl i
111Session ID, as displayed by
112.Nm
113.Fl v .
114.It Fl n
115The "nickname" of session defined in the configuration file.
116.It Fl p
117Target portal - host name or address - for statically defined targets.
118.It Fl s
119CHAP secret.
120.It Fl t
121Target name.
122.It Fl u
123CHAP login.
124.It Fl v
125Verbose mode.
126.It Fl w
127Instead of returning immediately, wait up to
128.Ar timeout
129seconds until all configured sessions are successfully established.
130.El
131.Pp
132Certain parameters are necessary when adding a session.
133One can specify these either via command line (using the
134.Fl t ,
135.Fl p ,
136.Fl u ,
137and
138.Fl s
139options), or configuration file (using the
140.Fl a
141or
142.Fl n
143options).
144Some functionality - for example mutual CHAP - is available only
145via configuration file.
146.Pp
147Since connecting to the target is performed in background, non-zero
148exit status does not mean that the session was successfully established.
149Use either
150.Nm Fl L
151to check the connection status, or the
152.Fl w
153flag to wait for session establishment.
154.Pp
155Note that in order for the iSCSI initiator to be able to connect to a target,
156the
157.Xr iscsid 8
158daemon must be running.
159.Pp
160Also note that
161.Fx
162currently supports two different initiators: the old one,
163.Xr iscsi_initiator 4 ,
164with its control utility
165.Xr iscontrol 8 ,
166and the new one,
167.Xr iscsi 4 ,
168with
169.Nm
170and
171.Xr iscsid 8 .
172The only thing the two have in common is the configuration file,
173.Xr iscsi.conf 5 .
174.Sh FILES
175.Bl -tag -width ".Pa /etc/iscsi.conf" -compact
176.It Pa /etc/iscsi.conf

178.El
179.Sh EXIT STATUS
180The
181.Nm
182utility exits 0 on success, and >0 if an error occurs.
183.Sh EXAMPLES
