799265368d4SRodney W. Grimes# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
800ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
801ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
802ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
803ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
804ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
