6896a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
6906a8d6623SGarrett Wollman
6916a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
692ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
6936a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
6946a8d6623SGarrett Wollman# device configuration sections below.
6956a8d6623SGarrett Wollman#
696265368d4SRodney W. Grimes# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
697ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
698ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
699ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
700ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
701ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
702ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
703ebc1a0e2SPeter Dufault# configuration around.
704ebc1a0e2SPeter Dufault
705ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit
706ebc1a0e2SPeter Dufault# assignment begins with the first non-wired down unit for a device
707700daf5eSJustin T. Gibbs# type.  For example, if you wire a disk as "da3" then the first
708700daf5eSJustin T. Gibbs# non-wired disk will be assigned da4.

2233f909c15bSEivind Eklund# The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
2234f909c15bSEivind Eklund# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
2235b755b885SEivind Eklund# The DPT controllers are commonly re-licensed under other brand-names -
2236b755b885SEivind Eklund# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
2237b755b885SEivind Eklund# Compaq are actually DPT controllers.
2238b755b885SEivind Eklund#
223916094866SJulian Elischer# See sys/dev/dpt for debugging and other subtle options.
224016094866SJulian Elischer#   DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
2241b755b885SEivind Eklund#                           instruments are enabled.  The tools in
2242b755b885SEivind Eklund#                           /usr/sbin/dpt_* assume these to be enabled.
224316094866SJulian Elischer#   DPT_HANDLE_TIMEOUTS     Normally device timeouts are handled by the DPT.
224416094866SJulian Elischer#                           If you ant the driver to handle timeouts, enable
224516094866SJulian Elischer#                           this option.  If your system is very busy, this
224616094866SJulian Elischer#                           option will create more trouble than solve.
224716094866SJulian Elischer#   DPT_TIMEOUT_FACTOR      Used to compute the excessive amount of time to
224816094866SJulian Elischer#                           wait when timing out with the above option.
224916094866SJulian Elischer#  DPT_DEBUG_xxxx           These are controllable from sys/dev/dpt/dpt.h
225016094866SJulian Elischer#  DPT_LOST_IRQ             When enabled, will try, once per second, to catch
225116094866SJulian Elischer#                           any interrupt that got lost.  Seems to help in some
225216094866SJulian Elischer#                           DPT-firmware/Motherboard combinations.  Minimal
225316094866SJulian Elischer#                           cost, great benefit.
2254b755b885SEivind Eklund#  DPT_RESET_HBA            Make "reset" actually reset the controller
2255b755b885SEivind Eklund#                           instead of fudging it.  Only enable this if you
2256b755b885SEivind Eklund#			    are 100% certain you need it.
