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

NAME
     isp -- Qlogic based SCSI 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 SCSI or FibreChannel devices.

     SCSI features include support for Ultra SCSI and wide mode	transactions
     for SCSI, Ultra2 LVD (for the ISP1080 and ISP1280), and Ultra3 LVD	(for
     the ISP12160).

     Fibre Channel support uses	FCP SCSI profile for FibreChannel, and uti-
     lizes Class 3 and Class 2 connections (Qlogic 2100	is Class 3 only, minor
     patches to	the Qlogic 2200	to force Class 2 mode).	 Support is available
     for Public	and Private loops, and for point-to-point connections (Qlogic
     2200 only).  The newer 2-Gigabit cards (2300, 2312, 2322) and 4-Gigabit
     (2422, 2432) are also supported.  Command tagging is supported for	all
     (in fact, FibreChannel requires tagging).	Fabric support is enabled by
     default for other than 2100 cards.	 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.

FIRMWARE
     Firmware is available if the ispfw(4) module is loaded during bootstrap
     (q.v.).

     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.

CONFIGURATION OPTIONS
     Target mode support 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.disable
	     A hint value to disable driver in kernel.

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

     hint.isp.0.prefer_memmap
	     A hint value to use PCI memory space instead of I/O space access
	     for.

     hint.isp.0.prefer_iomap
	     A hint value to use PCI I/O space instead of Memory space access
	     for.

     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 (target, initia-
	     tor, 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.

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.

BUGS
     The driver	currently ignores some NVRAM settings.

     Target mode support is not	completely reliable yet.  It works reasonably
     well for Fibre Channel, somewhat well for Qlogic 1040 cards, but does not
     yet work for the other cards (due to last minute unannounced changes in
     firmware interfaces).
