SYNOPSIS

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


.Cd device scbus
.Cd 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.

HARDWARE

Cards supported by the isp driver include:
Qlogic 1000
  Fast Wide, Ultra Fast Wide cards, Single Ended or Differential SBus cards.
Qlogic 1020
  Fast Wide and Differential Fast Wide SCSI PCI cards.

  Ultra Wide and Differential Ultra Wide SCSI PCI cards. Also known as the DEC KZPBA-CA (single ended) and KZPBA-CB (HVD differential).
Qlogic 1080
  LVD Ultra2 Wide SCSI PCI cards.
Qlogic 10160
  LVD Ultra3 Wide SCSI PCI cards.

  Dual Bus LVD Ultra2 Wide SCSI PCI cards.
Qlogic 12160
  Dual Bus LVD Ultra3 Wide SCSI PCI cards.
Qlogic 210X
  Copper and Optical Fibre Channel Arbitrated Loop PCI cards (single, dual).
Qlogic 220X
  Copper and Optical Fibre Channel Arbitrated Loop PCI cards (single, dual, quad).
Qlogic 2300
  Optical 2Gb Fibre Channel PCI cards.
Qlogic 2312

  Optical 2Gb Fibre Channel PCI cards (2312 chipset, single 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


.Cd 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
.An Matthew Jacob originally for NetBSD at NASA/Ames Research Center. Some later improvement was done by
.An Alexander Motin Aq Mt 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.
