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
     connections.

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.

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.
