The host adapters are listed in the ISA and PCI 647# device configuration sections below. 648# 649# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 650# that a given bus, target, and LUN always come on line as the same 651# device unit. In earlier versions the unit numbers were assigned 652# in the order that the devices were probed on the SCSI bus. This 653# means that if you removed a disk drive, you may have had to rewrite 654# your /etc/fstab file, and also that you had to be careful when adding 655# a new disk as it may have been probed earlier and moved your device 656# configuration around. 657 658# This old behavior is maintained as the default behavior. The unit 659# assignment begins with the first non-wired down unit for a device 660# type. For example, if you wire a disk as "da3" then the first 661# non-wired disk will be assigned da4. 662 663# The syntax for wiring down devices is: 664 665# device scbus0 at ahc0 # Single bus device 666# device scbus1 at ahc1 bus 0 # Single bus device 667# device scbus3 at ahc2 bus 0 # Twin bus device 668# device scbus2 at ahc2 bus 1 # Twin bus device 669# device da0 at scbus0 target 0 unit 0 670# device da1 at scbus3 target 1 671# device da2 at scbus2 target 3 672# device sa1 at scbus1 target 6 673# device cd 674 675# "units" (SCSI logical unit number) that are not specified are 676# treated as if specified as LUN 0. 677 678# All SCSI devices allocate as many units as are required. 679 680# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 681# configuration and doesn't have to be explicitly configured. 682 683device scbus #base SCSI code 684device ch #SCSI media changers 685device da #SCSI direct access devices (aka disks) 686device sa #SCSI tapes 687device cd #SCSI CD-ROMs 688device pass #CAM passthrough driver 689device sg #Passthrough device (linux scsi generic) 690device pt #SCSI processor type 691device ses #SCSI SES/SAF-TE driver 692device targ #SCSI Target Mode Code 693device targbh #SCSI Target Mode Blackhole Device 694 695# Options for device mapper 696device dm 697device dm_target_crypt 698device dm_target_linear 699device dm_target_striped 700device dm_target_delay 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.
