646 # SCSI DEVICE CONFIGURATION
648 # The SCSI subsystem consists of the `base' SCSI code, a number of
649 # high-level SCSI device `type' drivers, and the low-level host-adapter
650 # device drivers. The host adapters are listed in the ISA and PCI
651 # device configuration sections below.
653 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
654 # that a given bus, target, and LUN always come on line as the same
655 # device unit. In earlier versions the unit numbers were assigned
656 # in the order that the devices were probed on the SCSI bus. This
657 # means that if you removed a disk drive, you may have had to rewrite
658 # your /etc/fstab file, and also that you had to be careful when adding
659 # a new disk as it may have been probed earlier and moved your device
660 # configuration around.
662 # This old behavior is maintained as the default behavior. The unit
663 # assignment begins with the first non-wired down unit for a device
664 # type. For example, if you wire a disk as "da3" then the first
665 # non-wired disk will be assigned da4.
667 # The syntax for wiring down devices is:
669 # device scbus0 at ahc0 # Single bus device
670 # device scbus1 at ahc1 bus 0 # Single bus device
671 # device scbus3 at ahc2 bus 0 # Twin bus device
672 # device scbus2 at ahc2 bus 1 # Twin bus device
673 # device da0 at scbus0 target 0 unit 0
674 # device da1 at scbus3 target 1

1863 # The 'asr' driver provides support for current DPT/Adaptec SCSI RAID
1864 # controllers (SmartRAID V and VI and later).
1865 # These controllers require the CAM infrastructure.
1869 # The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
1870 # These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
1871 # The DPT controllers are commonly re-licensed under other brand-names -
1872 # some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
1873 # Compaq are actually DPT controllers.
1875 # See src/sys/dev/raid/dpt for debugging and other subtle options.
1876 # DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1877 # instruments are enabled. The tools in

1879 # DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
1880 # If you ant the driver to handle timeouts, enable
1881 # this option. If your system is very busy, this
1882 # option will create more trouble than solve.
1883 # DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
