845# SCSI DEVICES
846
847# SCSI DEVICE CONFIGURATION
848
849# The SCSI subsystem consists of the `base' SCSI code, a number of
850# high-level SCSI device `type' drivers, and the low-level host-adapter
851# device drivers. The host adapters are listed in the ISA and PCI
852# device configuration sections below.
853#
854# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
855# that a given bus, target, and LUN always come on line as the same
856# device unit. In earlier versions the unit numbers were assigned
857# in the order that the devices were probed on the SCSI bus. This
858# means that if you removed a disk drive, you may have had to rewrite
859# your /etc/fstab file, and also that you had to be careful when adding
860# a new disk as it may have been probed earlier and moved your device
861# configuration around.
862
863# This old behavior is maintained as the default behavior. The unit
864# assignment begins with the first non-wired down unit for a device
865# type. For example, if you wire a disk as "da3" then the first
866# non-wired disk will be assigned da4.
867
868# The syntax for wiring down devices is:
869
870# device scbus0 at ahc0 # Single bus device
871# device scbus1 at ahc1 bus 0 # Single bus device
872# device scbus3 at ahc2 bus 0 # Twin bus device
873# device scbus2 at ahc2 bus 1 # Twin bus device
874# device da0 at scbus0 target 0 unit 0
875# device da1 at scbus3 target 1
876# device da2 at scbus2 target 3
877# device sa1 at scbus1 target 6
878# device cd
879
880# "units" (SCSI logical unit number) that are not specified are
881# treated as if specified as LUN 0.
882
883# All SCSI devices allocate as many units as are required.

2187# The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
2188# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
2189# The DPT controllers are commonly re-licensed under other brand-names -
2190# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
2191# Compaq are actually DPT controllers.

2194# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
2195# instruments are enabled. The tools in

2197# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
2198# If you ant the driver to handle timeouts, enable
2199# this option. If your system is very busy, this
2200# option will create more trouble than solve.
2201# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
2202# wait when timing out with the above option.
