ISP(4)		       FreeBSD Kernel Interfaces Manual			ISP(4)

NAME
     isp -- Qlogic based SPI and FibreChannel SCSI Host	Adapters

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

	   device scbus
	   device isp

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

	   isp_load="YES"

DESCRIPTION
     This driver provides access to SPI	or FibreChannel	SCSI devices.

     SPI supports initiator mode for Ultra SCSI	and wide mode transactions for
     SCSI, Ultra2 LVD (1080, 1280), and	Ultra3 LVD (10160, 12160).

     Fibre Channel supports initiator and target modes of FCP SCSI profile,
     utilizing Class 3 and Class 2 (2200 and later) connections.  Support is
     available for Public and Private loops, Point-to-Point and	Fabric connec-
     tions.

FIRMWARE
     Firmware loading is supported if the ispfw(4) module is loaded.  It is
     strongly recommended that you use the firmware available from ispfw(4) as
     it	is the most likely to have been	tested with this driver.

		   and dual attach).

	   Qlogic 2322
		   Optical 2Gb Fibre Channel PCIe cards.

	   Qlogic 200
		   Dell	branded	version	of the QLogic 2312.

	   Qlogic 2422
		   Optical 4Gb Fibre Channel PCI cards.

	   Qlogic 246x (aka 2432)
		   Optical 4Gb Fibre Channel PCIe cards.

	   Qlogic 256x (aka 2532)
		   Optical 8Gb Fibre Channel PCIe cards.

	   Qlogic 267x/836x (aka 2031/8031)
		   Optical 16Gb	FC/FCoE	PCIe cards.

CONFIGURATION OPTIONS
     Target mode support for Fibre Channel adapters may	be enabled with	the

     options ISP_TARGET_MODE

     option.

BOOT OPTIONS
     The following options are switchable by setting values in
     /boot/device.hints.

     They are:

     hint.isp.0.fwload_disable
	     A hint value to disable loading of	firmware ispfw(4).

     hint.isp.0.ignore_nvram
	     A hint value to ignore board NVRAM	settings for.  Otherwise use
	     NVRAM settings.

     hint.isp.0.fullduplex
	     A hint value to set full duplex mode.

     hint.isp.0.topology
	     A hint value to select topology of	connection.  Supported values
	     are:

	     lport	 Prefer	loopback and fallback to point to point.
	     nport	 Prefer	point to point and fallback to loopback.
	     lport-only	 Loopback only.
	     nport-only	 Point to point	only.

     hint.isp.0.portwwn
	     This should be the	full 64	bit World Wide Port Name you would
	     like to use, overriding the value in NVRAM	for the	card.

     hint.isp.0.nodewwn
	     This should be the	full 64	bit World Wide Node Name you would
	     like to use, overriding the value in NVRAM	for the	card.

     hint.isp.0.iid
	     A hint to override	or set the Initiator ID	or Loop	ID.  For Fibre
	     Channel cards in Local Loop topologies it is strongly recommended
	     that you set this value to	non-zero.

     hint.isp.0.role
	     A hint to define default role for isp instance (0 -- none,	1 --
	     target, 2 -- initiator, 3 -- both).

     hint.isp.0.debug
	     A hint value for a	driver debug level (see	the file
	     /usr/src/sys/dev/isp/ispvar.h for the values.

     hint.isp.0.vports
	     A hint to create specified	number of additional virtual ports.

SYSCTL OPTIONS
     dev.isp.N.loop_down_limit
	     This value	says how long to wait in seconds after loop has	gone
	     down before giving	up and expiring	all of the devices that	were
	     visible.  The default is 300 seconds (5 minutes).	A separate
	     (nonadjustable) timeout is	used when booting to not stop booting
	     on	lack of	FC connectivity.

     dev.isp.N.gone_device_time
	     This value	says how long to wait for devices to reappear if they
	     (temporarily) disappear due to loop or fabric events.  While this
	     timeout is	running, I/O to	those devices will simply be held.

     dev.isp.N.wwnn
	     This is the readonly World	Wide Node Name value for this port.

     dev.isp.N.wwpn
	     This is the readonly World	Wide Port Name value for this port.

AUTHORS
     The isp driver was	written	by Matthew Jacob originally for	NetBSD at
     NASA/Ames Research	Center.	 Some later improvement	was done by
     Alexander Motin <mav@FreeBSD.org>.

BUGS
     The driver	currently ignores some NVRAM settings.

     Fabric support for	2100 cards has been so problematic, and	these cards
     are so old	now that it is just not	worth your time	to try it.
