CFISCSI(4)		    Kernel Interfaces Manual		    CFISCSI(4)

NAME
       cfiscsi -- CAM Target Layer iSCSI target	frontend

SYNOPSIS
       To  compile  this  driver into the kernel, place	the following lines in
       your kernel configuration file:

	     device cfiscsi
	     device ctl
	     device iscsi

       Alternatively, to load the driver as a module at	boot time,  place  the
       following line in loader.conf(5):

	     cfiscsi_load="YES"

DESCRIPTION
       The cfiscsi subsystem provides the kernel component of an iSCSI target.
       The  target  is	the iSCSI server, providing LUNs backed	by local files
       and volumes to remote initiators.  The userspace	component is  provided
       by  ctld(8).   cfiscsi is implemented as	a ctl(4) frontend and uses in-
       frastructure provided by	iscsi(4).

SYSCTL VARIABLES
       The following variables are available as	both sysctl(8)	variables  and
       loader(8) tunables:

       kern.cam.ctl.iscsi.debug
	       Verbosity  level	for log	messages from the kernel part of iSCSI
	       target.	Set to 0 to disable logging or 1 to warn about	poten-
	       tial  problems.	 Larger	 values	 enable	debugging output.  De-
	       faults to 1.

       kern.cam.ctl.iscsi.maxtags
	       The number of outstanding commands to advertise to  each	 iSCSI
	       initiator.   Current implementation is not very accurate, so do
	       not set this below 2.  Defaults to 256.

       kern.cam.ctl.iscsi.ping_timeout
	       The number of seconds to	wait for the iSCSI  initiator  to  re-
	       spond  to a NOP-In PDU.	In the event that there	is no response
	       within that time	the session gets forcibly terminated.  Set  to
	       0 to disable sending NOP-In PDUs.  Defaults to 5.

HISTORY
       The  cfiscsi  subsystem	first  appeared	in FreeBSD 10.0	as part	of the
       ctl(4) driver.  It was split off	of ctl(4) in FreeBSD 12.0.

AUTHORS
       The  cfiscsi  subsystem	was  developed	by  Edward  Tomasz   Napierala
       <trasz@FreeBSD.org>  under  sponsorship	from  the  FreeBSD Foundation.
       This manual page	was written by Enji Cooper <ngie@FreeBSD.org>.
