The host adapters are listed in the ISA and PCI 648# device configuration sections below. 649# 650# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 651# that a given bus, target, and LUN always come on line as the same 652# device unit. In earlier versions the unit numbers were assigned 653# in the order that the devices were probed on the SCSI bus. This 654# means that if you removed a disk drive, you may have had to rewrite 655# your /etc/fstab file, and also that you had to be careful when adding 656# a new disk as it may have been probed earlier and moved your device 657# configuration around. 658 659# This old behavior is maintained as the default behavior. The unit 660# assignment begins with the first non-wired down unit for a device 661# type. For example, if you wire a disk as "da3" then the first 662# non-wired disk will be assigned da4. 663 664# The syntax for wiring down devices is: 665 666# device scbus0 at ahc0 # Single bus device 667# device scbus1 at ahc1 bus 0 # Single bus device 668# device scbus3 at ahc2 bus 0 # Twin bus device 669# device scbus2 at ahc2 bus 1 # Twin bus device 670# device da0 at scbus0 target 0 unit 0 671# device da1 at scbus3 target 1 672# device da2 at scbus2 target 3 673# device sa1 at scbus1 target 6 674# device cd 675 676# "units" (SCSI logical unit number) that are not specified are 677# treated as if specified as LUN 0. 678 679# All SCSI devices allocate as many units as are required. 680 681# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 682# configuration and doesn't have to be explicitly configured. 683 684device scbus #base SCSI code 685device ch #SCSI media changers 686device da #SCSI direct access devices (aka disks) 687device sa #SCSI tapes 688device cd #SCSI CD-ROMs 689device pass #CAM passthrough driver 690device sg #Passthrough device (linux scsi generic) 691device pt #SCSI processor type 692device ses #SCSI SES/SAF-TE driver 693device targ #SCSI Target Mode Code 694device targbh #SCSI Target Mode Blackhole Device 695 696# Options for device mapper 697device dm 698device dm_target_crypt 699device dm_target_linear 700device dm_target_striped 701 702# Options for iSCSI 703device iscsi_initiator 704options ISCSI_INITIATOR_DEBUG=8 705 706# CAM OPTIONS: 707# debugging options: 708# -- NOTE -- If you specify one of the bus/target/lun options, you must 709# specify them all! 710# CAMDEBUG: When defined enables debugging macros 711# CAM_DEBUG_BUS: Debug the given bus.
