759 # SCSI DEVICE CONFIGURATION
761 # The SCSI subsystem consists of the `base' SCSI code, a number of
762 # high-level SCSI device `type' drivers, and the low-level host-adapter
763 # device drivers. The host adapters are listed in the ISA and PCI
764 # device configuration sections below.
766 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
767 # that a given bus, target, and LUN always come on line as the same
768 # device unit. In earlier versions the unit numbers were assigned
769 # in the order that the devices were probed on the SCSI bus. This
770 # means that if you removed a disk drive, you may have had to rewrite
771 # your /etc/fstab file, and also that you had to be careful when adding
772 # a new disk as it may have been probed earlier and moved your device
773 # configuration around.
775 # This old behavior is maintained as the default behavior. The unit
776 # assignment begins with the first non-wired down unit for a device
777 # type. For example, if you wire a disk as "da3" then the first
778 # non-wired disk will be assigned da4.
780 # The syntax for wiring down devices is:
782 # device scbus0 at ahc0 # Single bus device
783 # device scbus1 at ahc1 bus 0 # Single bus device
784 # device scbus3 at ahc2 bus 0 # Twin bus device
785 # device scbus2 at ahc2 bus 1 # Twin bus device
786 # device da0 at scbus0 target 0 unit 0
787 # device da1 at scbus3 target 1
788 # device da2 at scbus2 target 3
789 # device sa1 at scbus1 target 6
792 # "units" (SCSI logical unit number) that are not specified are
793 # treated as if specified as LUN 0.
795 # All SCSI devices allocate as many units as are required.
