875
876# SCSI DEVICE CONFIGURATION
877
878# The SCSI subsystem consists of the `base' SCSI code, a number of
879# high-level SCSI device `type' drivers, and the low-level host-adapter
880# device drivers. The host adapters are listed in the ISA and PCI
881# device configuration sections below.
882#
883# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
884# that a given bus, target, and LUN always come on line as the same
885# device unit. In earlier versions the unit numbers were assigned
886# in the order that the devices were probed on the SCSI bus. This
887# means that if you removed a disk drive, you may have had to rewrite
888# your /etc/fstab file, and also that you had to be careful when adding
889# a new disk as it may have been probed earlier and moved your device
890# configuration around.
891
892# This old behavior is maintained as the default behavior. The unit
893# assignment begins with the first non-wired down unit for a device
894# type. For example, if you wire a disk as "da3" then the first
895# non-wired disk will be assigned da4.
896
897# The syntax for wiring down devices is:
898
899# device scbus0 at ahc0 # Single bus device
900# device scbus1 at ahc1 bus 0 # Single bus device
901# device scbus3 at ahc2 bus 0 # Twin bus device
902# device scbus2 at ahc2 bus 1 # Twin bus device
903# device da0 at scbus0 target 0 unit 0
904# device da1 at scbus3 target 1
905# device da2 at scbus2 target 3
906# device sa1 at scbus1 target 6
907# device cd
908
909# "units" (SCSI logical unit number) that are not specified are
910# treated as if specified as LUN 0.
