33.Sh NAME
34.Nm iscsid
35.Nd iSCSI initiator daemon
36.Sh SYNOPSIS
37.Nm
38.Op Fl P Ar pidfile
39.Op Fl d
40.Op Fl l Ar loglevel
41.Op Fl m Ar maxproc
42.Op Fl t Ar seconds
43.Sh DESCRIPTION
44The
45.Nm
46daemon is responsible for performing the Login Phase of iSCSI connections,
47as well as performing SendTargets discovery.
48.Pp
49Upon startup, the
50.Nm
51daemon opens the iSCSI initiator device file and waits for kernel requests.
52.Nm
53does not use any configuration files.
54All needed information is supplied by the kernel.
55.Pp
56When the
57.Nm
58daemon is not running, already established iSCSI connections continue
59to work.
60However, establishing new connections, or recovering existing ones in case
61of connection error, is not possible.
62.Pp
63The following options are available:
64.Bl -tag -width ".Fl P Ar pidfile"
65.It Fl P Ar pidfile
66Specify alternative location of a file where main process PID will be stored.
67The default location is
68.Pa /var/run/iscsid.pid .
69.It Fl d
70Debug mode.
71The daemon sends verbose debug output to standard error, and does not
72put itself in the background.
73The daemon will also not fork and will exit after processing one connection.
74This option is only intended for debugging the initiator.
75.It Fl l Ar loglevel
76Specifies debug level.
77The default is 0.
78.It Fl m Ar maxproc
79Specifies limit for concurrently running child processes handling
80connections.
81The default is 30.
82Setting it to 0 disables the limit.
83.It Fl t Ar seconds
84Specifies timeout for login session, after which the connection
85will be forcibly terminated.
86The default is 60.
87Setting it to 0 disables the timeout.
88.El
89.Sh FILES
90.Bl -tag -width ".Pa /var/run/iscsid.pid" -compact
91.It Pa /dev/iscsi
92The iSCSI initiator device file.
93.It Pa /var/run/iscsid.pid
