868# SCSI DEVICE CONFIGURATION
869
870# The SCSI subsystem consists of the `base' SCSI code, a number of
871# high-level SCSI device `type' drivers, and the low-level host-adapter
872# device drivers. The host adapters are listed in the ISA and PCI
873# device configuration sections below.
874#
875# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
876# that a given bus, target, and LUN always come on line as the same
877# device unit. In earlier versions the unit numbers were assigned
878# in the order that the devices were probed on the SCSI bus. This
879# means that if you removed a disk drive, you may have had to rewrite
880# your /etc/fstab file, and also that you had to be careful when adding
881# a new disk as it may have been probed earlier and moved your device
882# configuration around.
883
884# This old behavior is maintained as the default behavior. The unit
885# assignment begins with the first non-wired down unit for a device
886# type. For example, if you wire a disk as "da3" then the first
887# non-wired disk will be assigned da4.
888
889# The syntax for wiring down devices is:
890
891# device scbus0 at ahc0 # Single bus device
892# device scbus1 at ahc1 bus 0 # Single bus device
893# device scbus3 at ahc2 bus 0 # Twin bus device
894# device scbus2 at ahc2 bus 1 # Twin bus device
895# device da0 at scbus0 target 0 unit 0
896# device da1 at scbus3 target 1
