79.Sh DESCRIPTION
80The
81.Nm
82utility is used to configure the iSCSI initiator.
83.Pp
84The following options are available:
85.Bl -tag -width ".Fl A"
86.It Fl -libxo
87Generate output via
88.Xr libxo 3
89in a selection of different human and machine readable formats.
90See
91.Xr xo_parse_args 3
92for details on command line arguments.
93.It Fl A
94Add session.
95.It Fl M
96Modify session.
97.It Fl R
98Remove session.
99.It Fl L
100List sessions.
101.It Fl a
102When adding, add all sessions defined in the configuration file.
103When removing, remove all currently established sessions.
104.It Fl c
105Path to the configuration file.
106The default is
107.Pa /etc/iscsi.conf .
108.It Fl d
109Target host name or address used for SendTargets discovery.
110When used, it will add a temporary discovery session.
111After discovery is done, sessions will be added for each discovered target,
112and the temporary discovery session will be removed.
113.It Fl i
114Session ID, as displayed by
115.Nm
116.Fl v .
117.It Fl n
118The "nickname" of session defined in the configuration file.
119.It Fl p
120Target portal - host name or address - for statically defined targets.
121.It Fl r
122Use iSER (iSCSI over RDMA) instead of plain iSCSI over TCP/IP.
123.It Fl s
124CHAP secret.
125.It Fl t
126Target name.
127.It Fl u
128CHAP login.
129.It Fl v
130Verbose mode.
131.It Fl w
132Instead of returning immediately, wait up to
133.Ar timeout
134seconds until all configured sessions are successfully established.
135.El
136.Pp
137Certain parameters are necessary when adding a session.
138One can specify these either via command line (using the
139.Fl t ,
140.Fl p ,
141.Fl u ,
142and
143.Fl s
144options), or configuration file (using the
145.Fl a
146or
147.Fl n
148options).
149Some functionality - for example mutual CHAP - is available only
150via configuration file.
151.Pp
152Since connecting to the target is performed in background, non-zero
153exit status does not mean that the session was successfully established.
154Use either
155.Nm Fl L
156to check the connection status, or the
157.Fl w
158flag to wait for session establishment.
159.Pp
160Note that in order for the iSCSI initiator to be able to connect to a target,
161the
162.Xr iscsid 8
163daemon must be running.
164.Pp
165Also note that
166.Fx
167currently supports two different initiators: the old one,
168.Xr iscsi_initiator 4 ,
169with its control utility
170.Xr iscontrol 8 ,
171and the new one,
172.Xr iscsi 4 ,
173with
174.Nm
175and
176.Xr iscsid 8 .
177The only thing the two have in common is the configuration file,
178.Xr iscsi.conf 5 .
179.Sh FILES
180.Bl -tag -width ".Pa /etc/iscsi.conf" -compact
181.It Pa /etc/iscsi.conf
182iSCSI initiator configuration file.
183.El
184.Sh EXIT STATUS
185The
186.Nm
187utility exits 0 on success, and >0 if an error occurs.
188.Sh EXAMPLES
