37 # The `makeoptions' parameter allows variables to be passed to the

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