7476a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
7486a8d6623SGarrett Wollman
7496a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
750ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
7516a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
7526a8d6623SGarrett Wollman# device configuration sections below.
7536a8d6623SGarrett Wollman#
754265368d4SRodney W. Grimes# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
755ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
756ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
757ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
758ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
759ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
760ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
761ebc1a0e2SPeter Dufault# configuration around.
762ebc1a0e2SPeter Dufault
763ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit

766700daf5eSJustin T. Gibbs# non-wired disk will be assigned da4.
