857# SCSI DEVICES
858
859# SCSI DEVICE CONFIGURATION
860
861# The SCSI subsystem consists of the `base' SCSI code, a number of
862# high-level SCSI device `type' drivers, and the low-level host-adapter
863# device drivers. The host adapters are listed in the ISA and PCI
864# device configuration sections below.
865#
866# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
867# that a given bus, target, and LUN always come on line as the same
868# device unit. In earlier versions the unit numbers were assigned
869# in the order that the devices were probed on the SCSI bus. This
870# means that if you removed a disk drive, you may have had to rewrite
871# your /etc/fstab file, and also that you had to be careful when adding
872# a new disk as it may have been probed earlier and moved your device
873# configuration around.
874
875# This old behavior is maintained as the default behavior. The unit
876# assignment begins with the first non-wired down unit for a device
877# type. For example, if you wire a disk as "da3" then the first
878# non-wired disk will be assigned da4.
879
880# The syntax for wiring down devices is:
881
882# device scbus0 at ahc0 # Single bus device
883# device scbus1 at ahc1 bus 0 # Single bus device
884# device scbus3 at ahc2 bus 0 # Twin bus device
885# device scbus2 at ahc2 bus 1 # Twin bus device
886# device da0 at scbus0 target 0 unit 0
887# device da1 at scbus3 target 1
888# device da2 at scbus2 target 3
889# device sa1 at scbus1 target 6
890# device cd
891
892# "units" (SCSI logical unit number) that are not specified are
893# treated as if specified as LUN 0.
894
895# All SCSI devices allocate as many units as are required.
