The host adapters are listed in the ISA and PCI 749# device configuration sections below. 750# 751# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 752# that a given bus, target, and LUN always come on line as the same 753# device unit. In earlier versions the unit numbers were assigned 754# in the order that the devices were probed on the SCSI bus. This 755# means that if you removed a disk drive, you may have had to rewrite 756# your /etc/fstab file, and also that you had to be careful when adding 757# a new disk as it may have been probed earlier and moved your device 758# configuration around. 759 760# This old behavior is maintained as the default behavior. The unit 761# assignment begins with the first non-wired down unit for a device 762# type. For example, if you wire a disk as "da3" then the first 763# non-wired disk will be assigned da4. 764 765# The syntax for wiring down devices is: 766 767# device scbus0 at ahc0 # Single bus device 768# device scbus1 at ahc1 bus 0 # Single bus device 769# device scbus3 at ahc2 bus 0 # Twin bus device 770# device scbus2 at ahc2 bus 1 # Twin bus device 771# device da0 at scbus0 target 0 unit 0 772# device da1 at scbus3 target 1 773# device da2 at scbus2 target 3 774# device sa1 at scbus1 target 6 775# device cd 776 777# "units" (SCSI logical unit number) that are not specified are 778# treated as if specified as LUN 0. 779 780# All SCSI devices allocate as many units as are required. 781 782# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 783# configuration and doesn't have to be explicitly configured. 784 785device scbus #base SCSI code 786device ch #SCSI media changers 787device da #SCSI direct access devices (aka disks) 788device sa #SCSI tapes 789device cd #SCSI CD-ROMs 790device pass #CAM passthrough driver 791device pt #SCSI processor type 792device ses #SCSI SES/SAF-TE driver 793device targ #SCSI target driver 794 795# CAM OPTIONS: 796# debugging options: 797# -- NOTE -- If you specify one of the bus/target/lun options, you must 798# specify them all! 799# CAMDEBUG: When defined enables debugging macros 800# CAM_DEBUG_BUS: Debug the given bus.
