82.Sh DESCRIPTION
83The
84.Nm
85utility is used to configure the iSCSI initiator.
86.Pp
87The following options are available:
88.Bl -tag -width ".Fl A"
89.It Fl -libxo
90Generate output via
91.Xr libxo 3
92in a selection of different human and machine readable formats.
93See
94.Xr xo_parse_args 3
95for details on command line arguments.
96.It Fl A
97Add session.
98.It Fl M
99Modify session.
100.It Fl R
101Remove session.
102.It Fl L
103List sessions.
104.It Fl a
105When adding, add all sessions defined in the configuration file.
106When removing, remove all currently established sessions.
107.It Fl c
108Path to the configuration file.
109The default is
110.Pa /etc/iscsi.conf .
111.It Fl d
112Target host name or address used for SendTargets discovery.
113When used, it will add a temporary discovery session.
114After discovery is done, sessions will be added for each discovered target,
115and the temporary discovery session will be removed.
116.It Fl e
117Enable or disable the session.
118This is ignored for discovery sessions, but gets passed down to normal
119sessions they add.
120.It Fl i
121Session ID, as displayed by
122.Nm
123.Fl v .
124.It Fl n
125The "nickname" of session defined in the configuration file.
126.It Fl p
127Target portal - host name or address - for statically defined targets.
128.It Fl r
129Use iSER (iSCSI over RDMA) instead of plain iSCSI over TCP/IP.
130.It Fl s
131CHAP secret.
132.It Fl t
133Target name.
134.It Fl u
135CHAP login.
136.It Fl v
137Verbose mode.
138.It Fl w
139Instead of returning immediately, wait up to
140.Ar timeout
141seconds until all configured sessions are successfully established.
142.El
143.Pp
144Certain parameters are necessary when adding a session.
145One can specify these either via command line (using the
146.Fl t ,
147.Fl p ,
148.Fl u ,
149and
150.Fl s
151options), or configuration file (using the
152.Fl a
153or
154.Fl n
155options).
156Some functionality - for example mutual CHAP - is available only
157via configuration file.
158.Pp
159Since connecting to the target is performed in background, non-zero
160exit status does not mean that the session was successfully established.
161Use either
162.Nm Fl L
163to check the connection status, or the
164.Fl w
165flag to wait for session establishment.
166.Pp
167Note that in order for the iSCSI initiator to be able to connect to a target,
168the
169.Xr iscsid 8
170daemon must be running.
171.Pp
172Also note that
173.Fx
174currently supports two different initiators: the old one,
175.Xr iscsi_initiator 4 ,
176with its control utility
177.Xr iscontrol 8 ,
178and the new one,
179.Xr iscsi 4 ,
180with
181.Nm
182and
183.Xr iscsid 8 .
184The only thing the two have in common is the configuration file,
185.Xr iscsi.conf 5 .
186.Sh FILES
187.Bl -tag -width ".Pa /etc/iscsi.conf" -compact
188.It Pa /etc/iscsi.conf
189iSCSI initiator configuration file.
190.El
191.Sh EXIT STATUS
192The
193.Nm
194utility exits 0 on success, and >0 if an error occurs.
195.Sh EXAMPLES
196Attach to target iqn.2012-06.com.example:target0, served by 192.168.1.1:
197.Dl Nm Fl A Fl t Ar iqn.2012-06.com.example:target0 Fl p Ar 192.168.1.1
198.Pp
199Perform discovery on 192.168.1.1, and add disabled sessions for each
200discovered target; use
201.Nm -M -e on
202to connect them:
203.Dl Nm Fl A Fl d Ar 192.168.1.1 Fl e Ar off
204.Pp
205Disconnect all iSCSI sessions:
