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 "-d discovery-host"
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 Ar path
108Path to the configuration file.
109The default is
110.Pa /etc/iscsi.conf .
111.It Fl d Ar discovery-host
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 Cm on Ns | Ns Cm off
117Enable or disable the session.
118This is ignored for discovery sessions, but gets passed down to normal
119sessions they add.
120.It Fl i Ar session-id
121Session ID, as displayed by
122.Nm
123.Fl v .
124.It Fl n Ar nickname
125The
126.Ar nickname
127of a session defined in the configuration file.
128.It Fl p Ar portal
129Target portal \(em host name or address \(em for statically defined targets.
130.It Fl r
131Use iSER (iSCSI over RDMA) instead of plain iSCSI over TCP/IP.
132.It Fl s Ar secret
133CHAP secret.
134.It Fl t Ar target
135Target name.
136.It Fl u Ar user
137CHAP login.
138.It Fl v
139Verbose mode.
140.It Fl w Ar timeout
141Instead of returning immediately, wait up to
142.Ar timeout
143seconds until all configured sessions are successfully established.
144.El
145.Pp
146Certain parameters are necessary when adding a session.
147One can specify these either via command line (using the
148.Fl t ,
149.Fl p ,
150.Fl u ,
151and
152.Fl s
153options), or configuration file (using the
154.Fl a
155or
156.Fl n
157options).
158Some functionality - for example mutual CHAP - is available only
159via configuration file.
160.Pp
161Since connecting to the target is performed in background, non-zero
162exit status does not mean that the session was successfully established.
163Use either
164.Nm Fl L
165to check the connection status, or the
166.Fl w
167flag to wait for session establishment.
168.Pp
169Note that in order for the iSCSI initiator to be able to connect to a target,
170the
171.Xr iscsid 8
172daemon must be running.
173.Pp
174Also note that
175.Fx
176currently supports two different initiators: the old one,
177.Xr iscsi_initiator 4 ,
178with its control utility
179.Xr iscontrol 8 ,
180and the new one,
181.Xr iscsi 4 ,
182with
183.Nm
184and
185.Xr iscsid 8 .
186The only thing the two have in common is the configuration file,
187.Xr iscsi.conf 5 .
188.Sh FILES
189.Bl -tag -width ".Pa /etc/iscsi.conf" -compact
190.It Pa /etc/iscsi.conf
191iSCSI initiator configuration file.
192.El
193.Sh EXIT STATUS
194The
195.Nm
196utility exits 0 on success, and >0 if an error occurs.
197.Sh EXAMPLES
198Attach to target iqn.2012-06.com.example:target0, served by 192.168.1.1:
199.Dl Nm Fl A Fl t Ar iqn.2012-06.com.example:target0 Fl p Ar 192.168.1.1
200.Pp
201Perform discovery on 192.168.1.1, and add disabled sessions for each
202discovered target; use
203.Nm -M -e on
204to connect them:
205.Dl Nm Fl A Fl d Ar 192.168.1.1 Fl e Ar off
206.Pp
207Disconnect all iSCSI sessions:
