.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
daemon is responsible for performing the Login Phase of iSCSI connections,
|
|
|
|
|
as well as performing SendTargets discovery.
|
|
|
|
|
.Pp
|
|
|
|
|
Upon startup, the
|
|
|
|
|
.Nm
|
|
|
|
|
daemon opens the iSCSI initiator device file and waits for kernel requests.
|
|
|
|
|
It doesn't use any configuration file; all the information it needs it gets
|
|
|
|
|
from the kernel.
|
|
|
|
|
.Pp
|
|
|
|
|
When the
|
|
|
|
|
.Nm
|
|
|
|
|
damon is not running, already established iSCSI connections continue
|
|
|
|
|
to work.
|
|
|
|
|
However, establishing new connections, or recovering existing ones in case
|
|
|
|
|
of connection error, is not possible.
|
|
|
|
|
.Pp
|
|
|
|
|
The following options are available:
|
|
|
|
|
.Bl -tag -width ".Fl P Ar pidfile"
|
|
|
|
|
.It Fl P Ar pidfile
|
|
|
|
|
Specify alternative location of a file where main process PID will be stored.
|
2013-09-14 21:43:18 +00:00
|
|
|
The default location is
|
|
|
|
|
.Pa /var/run/iscsid.pid .
|

|
|
|
.It Fl d
|
|
|
|
|
Debug mode.
|
|
|
|
|
The server sends verbose debug output to standard error, and does not
|
|
|
|
|
put itself in the background.
|
|
|
|
|
The server will also not fork and will exit after processing one connection.
|
|
|
|
|
This option is only intended for debugging the initiator.
|
|
|
|
|
.It Fl l Ar loglevel
|
|
|

Specifies debug level.
|

|

.It Fl m Ar maxproc
|
|
|
|
|
Specifies limit for concurrently running child processes handling
|
|
|
|
|
connections.
|
|
|
|
|
The default is 30.
|
|
|
|
|
Setting it to 0 disables the limit.
|
|
|
|
|
.It Fl t Ar seconds
|
|
|
|
|
Specifies timeout for login session, after which the connection
|
|
|
|
|
will be forcibly terminated.
|
|
|
|
|
The default is 60.
|
|
|
|
|
Setting it to 0 disables the timeout.
