ISCSI(4)	       FreeBSD Kernel Interfaces Manual		      ISCSI(4)

NAME
     iscsi -- iSCSI initiator

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

	   device iscsi

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

	   iscsi_load="YES"

DESCRIPTION
     The iscsi subsystem provides the kernel component of an iSCSI initiator,
     responsible for implementing the Full Feature Phase of the	iSCSI proto-
     col.  The initiator is the	iSCSI client, which connects to	an iSCSI tar-
     get, providing local access to a remote block device.  The	userland com-
     ponent is provided	by iscsid(8) and both the kernel and userland are con-
     figured using iscsictl(8).

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

     kern.iscsi.debug
	     Verbosity level for log messages from the iscsi driver.  Set to 0
	     to	disable	logging	or 1 to	warn about potential problems.	Larger
	     values enable debugging output.  Defaults to 1.

     kern.iscsi.ping_timeout
	     The number	of seconds to wait for the target to respond to	a NOP-
	     Out PDU.  In the event that there is no response within that time
	     the session gets forcibly restarted.  Set to 0 to disable sending
	     NOP-Out PDUs.  Defaults to	5.

     kern.iscsi.iscsid_timeout
	     The number	of seconds to wait for iscsid(8) to establish a	ses-
	     sion.  After that time iscsi will abort and retry.	 Defaults to
	     60.

     kern.iscsi.login_timeout
	     The number	of seconds to wait for a login attempt to succeed.
	     After that	time iscsi will	abort and retry.  Defaults to 60.

     kern.iscsi.maxtags
	     The maximum number	of outstanding IO requests.  Defaults to 255.

     kern.iscsi.fail_on_disconnection
	     Controls the behavior after an iSCSI connection has been dropped
	     due to network problems.  When set	to 1, a	dropped	connection
	     causes the	iSCSI device nodes to be destroyed.  After reconnect-
	     ing, they will be created again.  By default, the device nodes
	     are left intact.  While the connection is down all	input/output
	     operations	are suspended, to be retried after the connection is
	     reestablished.
