6746a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
6756a8d6623SGarrett Wollman
6766a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
677ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
6786a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
6796a8d6623SGarrett Wollman# device configuration sections below.
6806a8d6623SGarrett Wollman#
681265368d4SRodney W. Grimes# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
682ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
683ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
684ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
685ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
686ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
687ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
688ebc1a0e2SPeter Dufault# configuration around.
689ebc1a0e2SPeter Dufault
690ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit
691ebc1a0e2SPeter Dufault# assignment begins with the first non-wired down unit for a device
692700daf5eSJustin T. Gibbs# type.  For example, if you wire a disk as "da3" then the first
693700daf5eSJustin T. Gibbs# non-wired disk will be assigned da4.
