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

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

SYNOPSIS
     device isp

     For one or more SCSI busses:
     device scbus0

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 now available if the ispfw(4) module is loaded during boot-
     strap (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 the loader con-
     figuration file (see the loader(8) manual page).  They are:

     isp_disable    A bit mask of units to skip configuration for.
     isp_mem_map    A bit mask of units to use PCI Memory space instead of I/O
                    space access for.
     isp_io_map     A bit mask of units to use PCI I/O space instead of Memory
                    space access for.
     isp_no_nvram   A bit mask of units that you wish to ignore board NVRAM
                    settings for.
     isp_nvram      A bit mask of units that you wish to specifically use
                    board NVRAM settings for.
     isp_fcduplex   A bit mask of units that you wish to specifically to set
                    into full duplex mode.
     isp_no_fcduplex
                    A bit mask of units that you wish to specifically to not
                    set into full duplex mode.
     isp_wwn        This should be the full 64 bit World Wide Node Name you
                    would like to use, overriding the value in NVRAM for the
                    card.
     isp_debug      This is a driver debug level- meaningful from 0 through 7.
     isp_tdebug     This is a driver target mode debug level- meaningful from
                    0 through 5.

BUGS
     The driver currently ignores some NVRAM settings.

     The driver currently doesn't do error recovery for timed out commands
     very gracefully.

     Target mode support isn't completely debugged yet.  It works reasonably
     well for Fibre Channel, somewhat well for Qlogic 1040 cards, but doesn't
     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.
