9076a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
9086a8d6623SGarrett Wollman
9096a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
910ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
9116a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
9126a8d6623SGarrett Wollman# device configuration sections below.
9136a8d6623SGarrett Wollman#
914265368d4SRodney W. Grimes# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
915ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
916ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
917ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
918ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
919ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
920ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
921ebc1a0e2SPeter Dufault# configuration around.
922ebc1a0e2SPeter Dufault
923ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit
924ebc1a0e2SPeter Dufault# assignment begins with the first non-wired down unit for a device
925700daf5eSJustin T. Gibbs# type.  For example, if you wire a disk as "da3" then the first
926700daf5eSJustin T. Gibbs# non-wired disk will be assigned da4.
