627 # SCSI DEVICE CONFIGURATION
629 # The SCSI subsystem consists of the `base' SCSI code, a number of
630 # high-level SCSI device `type' drivers, and the low-level host-adapter
631 # device drivers. The host adapters are listed in the ISA and PCI
632 # device configuration sections below.
634 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
635 # that a given bus, target, and LUN always come on line as the same
636 # device unit. In earlier versions the unit numbers were assigned
637 # in the order that the devices were probed on the SCSI bus. This
638 # means that if you removed a disk drive, you may have had to rewrite
639 # your /etc/fstab file, and also that you had to be careful when adding
640 # a new disk as it may have been probed earlier and moved your device
641 # configuration around.
643 # This old behavior is maintained as the default behavior. The unit
644 # assignment begins with the first non-wired down unit for a device
645 # type. For example, if you wire a disk as "da3" then the first
646 # non-wired disk will be assigned da4.
648 # The syntax for wiring down devices is:
650 # device scbus0 at ahc0 # Single bus device
651 # device scbus1 at ahc1 bus 0 # Single bus device
652 # device scbus3 at ahc2 bus 0 # Twin bus device
653 # device scbus2 at ahc2 bus 1 # Twin bus device
654 # device da0 at scbus0 target 0 unit 0
655 # device da1 at scbus3 target 1
656 # device da2 at scbus2 target 3
657 # device sa1 at scbus1 target 6
660 # "units" (SCSI logical unit number) that are not specified are
661 # treated as if specified as LUN 0.
663 # All SCSI devices allocate as many units as are required.

666 # configuration and doesn't have to be explicitly configured.

1881 # The 'asr' driver provides support for current DPT/Adaptec SCSI RAID
1882 # controllers (SmartRAID V and VI and later).
1883 # These controllers require the CAM infrastructure.
1887 # The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
1888 # These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
1889 # The DPT controllers are commonly re-licensed under other brand-names -
1890 # some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
1891 # Compaq are actually DPT controllers.
1893 # See src/sys/dev/raid/dpt for debugging and other subtle options.
1894 # DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1895 # instruments are enabled. The tools in
1896 # /usr/sbin/dpt_* assume these to be enabled.
1897 # DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
1898 # If you ant the driver to handle timeouts, enable
1899 # this option. If your system is very busy, this
1900 # option will create more trouble than solve.
1901 # DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
1902 # wait when timing out with the above option.
1903 # DPT_DEBUG_xxxx These are controllable from sys/dev/raid/dpt/dpt.h
1904 # DPT_LOST_IRQ When enabled, will try, once per second, to catch
1905 # any interrupt that got lost. Seems to help in some
1906 # DPT-firmware/Motherboard combinations. Minimal
1907 # cost, great benefit.
1908 # DPT_RESET_HBA Make "reset" actually reset the controller
1909 # instead of fudging it. Only enable this if you
1910 # are 100% certain you need it.
