890265368d4SRodney W. Grimes# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
891ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
892ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
893ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
894ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
895ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
896ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
897ebc1a0e2SPeter Dufault# configuration around.
898ebc1a0e2SPeter Dufault
899ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit
900ebc1a0e2SPeter Dufault# assignment begins with the first non-wired down unit for a device
901700daf5eSJustin T. Gibbs# type.  For example, if you wire a disk as "da3" then the first
902700daf5eSJustin T. Gibbs# non-wired disk will be assigned da4.
