7616a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
7626a8d6623SGarrett Wollman
7636a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
764ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
7656a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
7666a8d6623SGarrett Wollman# device configuration sections below.
7676a8d6623SGarrett Wollman#
768265368d4SRodney W. Grimes# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
769ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
770ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
771ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
772ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
773ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
774ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
775ebc1a0e2SPeter Dufault# configuration around.
776ebc1a0e2SPeter Dufault
777ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit
778ebc1a0e2SPeter Dufault# assignment begins with the first non-wired down unit for a device
