23 # This is the ``identification'' of the kernel. Usually this should
24 # be the same as the name of your kernel.
29 # The `maxusers' parameter controls the static sizing of a number of

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

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

1883 # The 'asr' driver provides support for current DPT/Adaptec SCSI RAID
1884 # controllers (SmartRAID V and VI and later).
1885 # These controllers require the CAM infrastructure.
1889 # The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
1890 # These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
1891 # The DPT controllers are commonly re-licensed under other brand-names -
1892 # some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
1893 # Compaq are actually DPT controllers.
1895 # See src/sys/dev/raid/dpt for debugging and other subtle options.
1896 # DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1897 # instruments are enabled. The tools in
1898 # /usr/sbin/dpt_* assume these to be enabled.
1899 # DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
1900 # If you ant the driver to handle timeouts, enable
1901 # this option. If your system is very busy, this
1902 # option will create more trouble than solve.
1903 # DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
1904 # wait when timing out with the above option.
1905 # DPT_DEBUG_xxxx These are controllable from sys/dev/raid/dpt/dpt.h
1906 # DPT_LOST_IRQ When enabled, will try, once per second, to catch
1907 # any interrupt that got lost. Seems to help in some
1908 # DPT-firmware/Motherboard combinations. Minimal
1909 # cost, great benefit.
1910 # DPT_RESET_HBA Make "reset" actually reset the controller
1911 # instead of fudging it. Only enable this if you
1912 # are 100% certain you need it.
