7086a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
7096a8d6623SGarrett Wollman
7106a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
711ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
7126a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
7136a8d6623SGarrett Wollman# device configuration sections below.
7146a8d6623SGarrett Wollman#
715265368d4SRodney W. Grimes# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
716ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
717ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
718ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
719ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
720ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
721ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
722ebc1a0e2SPeter Dufault# configuration around.
723ebc1a0e2SPeter Dufault
724ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit
725ebc1a0e2SPeter Dufault# assignment begins with the first non-wired down unit for a device
726700daf5eSJustin T. Gibbs# type.  For example, if you wire a disk as "da3" then the first
727700daf5eSJustin T. Gibbs# non-wired disk will be assigned da4.
728ebc1a0e2SPeter Dufault

2275f909c15bSEivind Eklund# The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
2276f909c15bSEivind Eklund# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
2277b755b885SEivind Eklund# The DPT controllers are commonly re-licensed under other brand-names -
2278b755b885SEivind Eklund# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
2279b755b885SEivind Eklund# Compaq are actually DPT controllers.

228198a44096SSheldon Hearn# See src/sys/dev/dpt for debugging and other subtle options.
228216094866SJulian Elischer#   DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
2283b755b885SEivind Eklund#                           instruments are enabled.  The tools in
2284b755b885SEivind Eklund#                           /usr/sbin/dpt_* assume these to be enabled.
228516094866SJulian Elischer#   DPT_HANDLE_TIMEOUTS     Normally device timeouts are handled by the DPT.
228616094866SJulian Elischer#                           If you ant the driver to handle timeouts, enable
228716094866SJulian Elischer#                           this option.  If your system is very busy, this
228816094866SJulian Elischer#                           option will create more trouble than solve.

229016094866SJulian Elischer#                           wait when timing out with the above option.
229116094866SJulian Elischer#  DPT_DEBUG_xxxx           These are controllable from sys/dev/dpt/dpt.h
229216094866SJulian Elischer#  DPT_LOST_IRQ             When enabled, will try, once per second, to catch
229316094866SJulian Elischer#                           any interrupt that got lost.  Seems to help in some
229416094866SJulian Elischer#                           DPT-firmware/Motherboard combinations.  Minimal
229516094866SJulian Elischer#                           cost, great benefit.
2296b755b885SEivind Eklund#  DPT_RESET_HBA            Make "reset" actually reset the controller
2297b755b885SEivind Eklund#                           instead of fudging it.  Only enable this if you
