32 .Nd login/negotiator/control for an iSCSI initiator session
39 .Op Ar variable Ns = Ns Ar value ...
41 Internet SCSI (iSCSI) is a network protocol standard, that allows the
42 use of the SCSI protocol over TCP/IP networks, the
44 program is the userland side of an iSCSI session, see
45 .Xr iscsi_initiator 4 .
46 It has two modes of operation, if
48 (discovery session) is specified,
51 returned by the target and exit.
52 In the second mode, it will, after a successful login/negotiation, run
53 in daemon mode, monitoring the connection, and will try to reconnect
54 in case of a network/target failure.
55 It will terminate/logout the session
56 when a SIGHUP signal is received.
57 The flags are as follows:
58 .Bl -tag -width variable=value
60 a file containing configuration
71 search for the block named
73 in the configuration file
78 is the target's IP address or name.
81 .It Ar variable Ns = Ns Ar value
84 for the complete list of variables/options and their
88 .Bl -tag -width /etc/iscsi.conf -compact
89 .It Pa /etc/iscsi.conf
90 default configuration file
93 .Dl iscontrol -dt myiscsitarget
98 print to stdout the list of available targetnames/targetadresses.
99 Note: this listing does not necessarily mean availability, since
100 depending on the target configuration, a discovery session might
101 not need login/access permission, but a
105 .Dl iscontrol -c myiscsi.conf -n myiscsi
107 will read options from
109 use the targetaddress
110 found in the block nicknamed myiscsi, login and negotiate
111 whatever options are specified, and start an iscsi-session.

130 missing are the Task Management Functions.
131 The error recovery, though not
133 does a brave effort to recover from network disconnects.
