6076a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
6086a8d6623SGarrett Wollman
6096a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
610ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
6116a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
6126a8d6623SGarrett Wollman# device configuration sections below.
6136a8d6623SGarrett Wollman#
614265368d4SRodney W. Grimes# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
615ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
616ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
617ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
618ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
619ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
620ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
621ebc1a0e2SPeter Dufault# configuration around.
622ebc1a0e2SPeter Dufault
623ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit
624ebc1a0e2SPeter Dufault# assignment begins with the first non-wired down unit for a device
625700daf5eSJustin T. Gibbs# type.  For example, if you wire a disk as "da3" then the first
626700daf5eSJustin T. Gibbs# non-wired disk will be assigned da4.
627ebc1a0e2SPeter Dufault
628ebc1a0e2SPeter Dufault# The syntax for wiring down devices is:

1711f909c15bSEivind Eklund# The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
1712f909c15bSEivind Eklund# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
1713b755b885SEivind Eklund# The DPT controllers are commonly re-licensed under other brand-names -
1714b755b885SEivind Eklund# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
1715b755b885SEivind Eklund# Compaq are actually DPT controllers.
1716b755b885SEivind Eklund#
171716094866SJulian Elischer# See sys/dev/dpt for debugging and other subtle options.
171816094866SJulian Elischer#   DPT_VERIFY_HINTR        Performs some strict hardware interrupts testing.
171916094866SJulian Elischer#                           Only use if you suspect PCI bus corruption problems
172016094866SJulian Elischer#   DPT_RESTRICTED_FREELIST Normally, the freelisat used by the DPT for queue
172116094866SJulian Elischer#                           will grow to accomodate increased use.  This growth
172216094866SJulian Elischer#                           will NOT shrink.  To restrict the number of queue
172316094866SJulian Elischer#                           slots to exactly what the DPT can hold at one time,
172416094866SJulian Elischer#                           enable this option.
172516094866SJulian Elischer#   DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1726b755b885SEivind Eklund#                           instruments are enabled.  The tools in
1727b755b885SEivind Eklund#                           /usr/sbin/dpt_* assume these to be enabled.
1728b755b885SEivind Eklund#   DPT_FREELIST_IS_STACK   For optimal L{1,2} CPU cache utilization, enable
172916094866SJulian Elischer#                           this option.  Otherwise, the transaction queue is
173016094866SJulian Elischer#                           a LIFO.  I cannot measure the performance gain.
173116094866SJulian Elischer#   DPT_HANDLE_TIMEOUTS     Normally device timeouts are handled by the DPT.
173216094866SJulian Elischer#                           If you ant the driver to handle timeouts, enable
173316094866SJulian Elischer#                           this option.  If your system is very busy, this
173416094866SJulian Elischer#                           option will create more trouble than solve.
173516094866SJulian Elischer#   DPT_TIMEOUT_FACTOR      Used to compute the excessive amount of time to
173616094866SJulian Elischer#                           wait when timing out with the above option.
173716094866SJulian Elischer#  DPT_DEBUG_xxxx           These are controllable from sys/dev/dpt/dpt.h
173816094866SJulian Elischer#  DPT_LOST_IRQ             When enabled, will try, once per second, to catch
173916094866SJulian Elischer#                           any interrupt that got lost.  Seems to help in some
174016094866SJulian Elischer#                           DPT-firmware/Motherboard combinations.  Minimal
174116094866SJulian Elischer#                           cost, great benefit.
1742b755b885SEivind Eklund#  DPT_RESET_HBA            Make "reset" actually reset the controller
1743b755b885SEivind Eklund#                           instead of fudging it.  Only enable this if you
1744b755b885SEivind Eklund#			    are 100% certain you need it.
1745b755b885SEivind Eklund#  DPT_SHUTDOWN_SLEEP       Reset controller if a request take more than
1746b755b885SEivind Eklund#                           this number of seconds.  Do NOT enable this
1747b755b885SEivind Eklund#			    unless you are really, really, really certain
1748b755b885SEivind Eklund#			    you need it.  You are advised to call Simon (the
1749b755b885SEivind Eklund#			    driver author) before setting it, and NEVER,
1750b755b885SEivind Eklund#			    EVER set it to less than 300s (5 minutes).
