30.Sh NAME
31.Nm iscsid
32.Nd iSCSI initiator daemon
33.Sh SYNOPSIS
34.Nm
35.Op Fl P Ar pidfile
36.Op Fl d
37.Op Fl l Ar loglevel
38.Op Fl m Ar maxproc
39.Op Fl t Ar seconds
40.Sh DESCRIPTION
41The
42.Nm
43daemon is the userspace component of the iSCSI initiator,
44responsible for performing the Login Phase
45of iSCSI connections and the SendTargets discovery.
46.Pp
47Upon startup, the
48.Nm
49daemon opens the iSCSI initiator device file and waits for requests
50from the kernel component,
51.Xr iscsi 4 .
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
94The default location of the
95.Nm
96PID file.
