# SCSI DEVICES
# SCSI DEVICE CONFIGURATION
# The SCSI subsystem consists of the `base' SCSI code, a number of
# high-level SCSI device `type' drivers, and the low-level host-adapter
# device drivers. The host adapters are listed in the ISA and PCI
# device configuration sections below.
#
# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
# that a given bus, target, and LUN always come on line as the same
# device unit. In earlier versions the unit numbers were assigned
# in the order that the devices were probed on the SCSI bus. This
# means that if you removed a disk drive, you may have had to rewrite
# your /etc/fstab file, and also that you had to be careful when adding
# a new disk as it may have been probed earlier and moved your device
# configuration around.
# This old behavior is maintained as the default behavior. The unit
# assignment begins with the first non-wired down unit for a device
# type. For example, if you wire a disk as "da3" then the first
# non-wired disk will be assigned da4.
# The syntax for wiring down devices is:
# device scbus0 at ahc0 # Single bus device
# device scbus1 at ahc1 bus 0 # Single bus device
# device scbus3 at ahc2 bus 0 # Twin bus device
# device scbus2 at ahc2 bus 1 # Twin bus device
# device da0 at scbus0 target 0 unit 0
# device da1 at scbus3 target 1
# device da2 at scbus2 target 3
# device sa1 at scbus1 target 6
# device cd
# "units" (SCSI logical unit number) that are not specified are
# treated as if specified as LUN 0.
# All SCSI devices allocate as many units as are required.
# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI

# The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
# The DPT controllers are commonly re-licensed under other brand-names -
# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
# Compaq are actually DPT controllers.
#
# See src/sys/dev/raid/dpt for debugging and other subtle options.
# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
# instruments are enabled. The tools in
# /usr/sbin/dpt_* assume these to be enabled.
# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
# If you ant the driver to handle timeouts, enable
# this option. If your system is very busy, this
# option will create more trouble than solve.
# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
# wait when timing out with the above option.
# DPT_DEBUG_xxxx These are controllable from sys/dev/raid/dpt/dpt.h
# DPT_LOST_IRQ When enabled, will try, once per second, to catch
# any interrupt that got lost. Seems to help in some
