CFISCSI(4)	       FreeBSD 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 infra-
     structure 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 potential
	     problems.	Larger values enable debugging output.	Defaults 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 respond
	     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 dis-
	     able sending NOP-In PDUs.	Defaults to 5.

SEE ALSO
     ctl(4), iscsi(4), ctl.conf(5), ctld(8)

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	Ngie Cooper <ngie@FreeBSD.org>.
