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) are also supported.
     Command tagging is supported for all (in fact, FibreChannel requires tag-
     ging).  Fabric support is enabled by default (but may be contingent upon
     the correct firmware being loaded).

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

     It is very 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 (principally for SPI
             SCSI).

     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 (values from 0 through 7).
             Default is 0.

AUTHORS
     The isp driver was written by Matthew Jacob for NASA/Ames Research Cen-
     ter.

BUGS
     The driver currently ignores some NVRAM settings.

     The driver currently does not do error recovery for timed out commands
     very gracefully.

     Target mode support is not completely debugged 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).

     Sometimes, when booting, the driver gets stuck waiting for the Fibre
     Channel f/w to tell it that the loop port database is ready, or waiting
     for a good loop to be seen (this does not yet support booting without
     being connected to a fibre channel device).  To unwedge the system,
     unplug and replug the fibre channel connection, or otherwise cause a LIP
     (Loop Initialization Primitive sequence)- this will kick the f/w into
     getting unstuck.

     QLogic 2322 support is limited to platforms where the BIOS can enable
     firmware as there is no code yet to do the 3 stage loading for 2322
     firmware.
