The host adapters are listed in the ISA and PCI 651# device configuration sections below. 652# 653# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 654# that a given bus, target, and LUN always come on line as the same 655# device unit. In earlier versions the unit numbers were assigned 656# in the order that the devices were probed on the SCSI bus. This 657# means that if you removed a disk drive, you may have had to rewrite 658# your /etc/fstab file, and also that you had to be careful when adding 659# a new disk as it may have been probed earlier and moved your device 660# configuration around. 661 662# This old behavior is maintained as the default behavior. The unit 663# assignment begins with the first non-wired down unit for a device 664# type. For example, if you wire a disk as "da3" then the first 665# non-wired disk will be assigned da4. 666 667# The syntax for wiring down devices is: 668 669# device scbus0 at ahc0 # Single bus device 670# device scbus1 at ahc1 bus 0 # Single bus device 671# device scbus3 at ahc2 bus 0 # Twin bus device 672# device scbus2 at ahc2 bus 1 # Twin bus device 673# device da0 at scbus0 target 0 unit 0 674# device da1 at scbus3 target 1 675# device da2 at scbus2 target 3 676# device sa1 at scbus1 target 6 677# device cd 678 679# "units" (SCSI logical unit number) that are not specified are 680# treated as if specified as LUN 0. 681 682# All SCSI devices allocate as many units as are required. 683 684# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 685# configuration and doesn't have to be explicitly configured. 686 687device scbus #base SCSI code 688device ch #SCSI media changers 689device da #SCSI direct access devices (aka disks) 690device sa #SCSI tapes 691device cd #SCSI CD-ROMs 692device pass #CAM passthrough driver 693device sg #Passthrough device (linux scsi generic) 694device pt #SCSI processor type 695device ses #SCSI SES/SAF-TE driver 696device targ #SCSI Target Mode Code 697device targbh #SCSI Target Mode Blackhole Device 698 699# Options for device mapper 700device dm 701device dm_target_crypt 702device dm_target_linear 703device dm_target_striped 704 705# Options for iSCSI 706device iscsi_initiator 707options ISCSI_INITIATOR_DEBUG=8 708 709# CAM OPTIONS: 710# debugging options: 711# -- NOTE -- If you specify one of the bus/target/lun options, you must 712# specify them all! 713# CAMDEBUG: When defined enables debugging macros 714# CAM_DEBUG_BUS: Debug the given bus.
