62.Sh DESCRIPTION
63The
64.Nm
65utility is used to configure the iSCSI initiator.
66.Pp
67The following options are available:
68.Bl -tag -width ".Fl A"
69.It Fl A
70Add session.
71.It Fl R
72Remove session.
73.It Fl L
74List sessions.
75.It Fl a
76When adding, add all sessions defined in the configuration file.
77When removing, remove all currently established sessions.
78.It Fl c
79Path to the configuration file.
80The default is
81.Pa /etc/iscsi.conf .
82.It Fl d
83Target host name or address used for SendTargets discovery.
84When used, it will add a temporary discovery session.
85After discovery is done, sessions will be added for each discovered target,
86and the temporary discovery sesion will be removed.
87.It Fl n
88The "nickname" of session defined in the configuration file.
89.It Fl p
90Target portal - host name or address - for statically defined targets.
91.It Fl s
92CHAP secret.
93.It Fl t
94Target name.
95.It Fl u
96CHAP login.
97.It Fl v
98Verbose mode.
99.El
100.Pp
101Certain parameters are neccessary when adding a session.
102One can specify these either via command line (using the
103.Fl t ,
104.Fl p ,
105.Fl u ,
106and
107.Fl s
108options), or configuration file (using the
109.Fl a
110or
111.Fl n
112options).
113Some functionality - for example mutual CHAP - is available only
114via configuration file.
115.Pp
116Since connecting to the target is performed in background, non-zero
117exit status does not mean that the session was successfully established.
118Use
119.Nm Fl L
120to check the connection status.
121.Pp
122Note that in order for the iSCSI initiator to be able to connect to a target,
123the
124.Xr iscsid 8
125daemon must be running.
126.Pp
127Also note that
128.Fx
129currently supports two different initiators: the old one,
130.Xr iscsi_initiator 4 ,
131with its control utility
132.Xr iscontrol 8 ,
133and the new one,
134.Xr iscsi 4 ,
135with
136.Nm
137and
138.Xr iscsid 8 .
139The only thing the two have in common is the configuration file,
140.Xr iscsi.conf 5 .
141.Sh FILES

146.Sh EXIT STATUS
147The
148.Nm
149utility exits 0 on success, and >0 if an error occurs.
150.Sh EXAMPLES
