798ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
799ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
800ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
801ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
