719# SCSI DEVICES
720
721# SCSI DEVICE CONFIGURATION
722
723# The SCSI subsystem consists of the `base' SCSI code, a number of
724# high-level SCSI device `type' drivers, and the low-level host-adapter
725# device drivers. The host adapters are listed in the ISA and PCI
726# device configuration sections below.
727#
728# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
729# that a given bus, target, and LUN always come on line as the same
730# device unit. In earlier versions the unit numbers were assigned
731# in the order that the devices were probed on the SCSI bus. This
732# means that if you removed a disk drive, you may have had to rewrite
733# your /etc/fstab file, and also that you had to be careful when adding
734# a new disk as it may have been probed earlier and moved your device
735# configuration around.
736
737# This old behavior is maintained as the default behavior. The unit
738# assignment begins with the first non-wired down unit for a device
739# type. For example, if you wire a disk as "da3" then the first
740# non-wired disk will be assigned da4.
741
742# The syntax for wiring down devices is:
743
744# device scbus0 at ahc0 # Single bus device
745# device scbus1 at ahc1 bus 0 # Single bus device
746# device scbus3 at ahc2 bus 0 # Twin bus device
747# device scbus2 at ahc2 bus 1 # Twin bus device
748# device da0 at scbus0 target 0 unit 0
749# device da1 at scbus3 target 1
750# device da2 at scbus2 target 3
751# device sa1 at scbus1 target 6
752# device cd
753
754# "units" (SCSI logical unit number) that are not specified are
755# treated as if specified as LUN 0.
756
757# All SCSI devices allocate as many units as are required.
