The host adapters are listed in the ISA and PCI # device configuration sections below. # # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so # that a given bus, target, and LUN always come on line as the same # device unit. In earlier versions the unit numbers were assigned # in the order that the devices were probed on the SCSI bus. This # means that if you removed a disk drive, you may have had to rewrite # your /etc/fstab file, and also that you had to be careful when adding # a new disk as it may have been probed earlier and moved your device # configuration around. # This old behavior is maintained as the default behavior. The unit # assignment begins with the first non-wired down unit for a device # type. For example, if you wire a disk as "da3" then the first # non-wired disk will be assigned da4. # The syntax for wiring down devices is: # device scbus0 at ahc0 # Single bus device # device scbus1 at ahc1 bus 0 # Single bus device # device scbus3 at ahc2 bus 0 # Twin bus device # device scbus2 at ahc2 bus 1 # Twin bus device # device da0 at scbus0 target 0 unit 0 # device da1 at scbus3 target 1 # device da2 at scbus2 target 3 # device sa1 at scbus1 target 6 # device cd # "units" (SCSI logical unit number) that are not specified are # treated as if specified as LUN 0. # All SCSI devices allocate as many units as are required. # The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI # configuration and doesn't have to be explicitly configured. device scbus #base SCSI code device ch #SCSI media changers device da #SCSI direct access devices (aka disks) device sa #SCSI tapes device cd #SCSI CD-ROMs device pass #CAM passthrough driver device sg #Passthrough device (linux scsi generic) device pt #SCSI processor type device ses #SCSI SES/SAF-TE driver device targ #SCSI Target Mode Code device targbh #SCSI Target Mode Blackhole Device # Options for device mapper device dm device dm_target_crypt device dm_target_linear device dm_target_striped # Options for iSCSI device iscsi_initiator options ISCSI_INITIATOR_DEBUG=8 # CAM OPTIONS: # debugging options: # -- NOTE -- If you specify one of the bus/target/lun options, you must # specify them all! # CAMDEBUG: When defined enables debugging macros # CAM_DEBUG_BUS: Debug the given bus.
