830# SCSI DEVICES
831
832# SCSI DEVICE CONFIGURATION
833
834# The SCSI subsystem consists of the `base' SCSI code, a number of
835# high-level SCSI device `type' drivers, and the low-level host-adapter
836# device drivers. The host adapters are listed in the ISA and PCI
837# device configuration sections below.
838#
839# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
840# that a given bus, target, and LUN always come on line as the same
841# device unit. In earlier versions the unit numbers were assigned
842# in the order that the devices were probed on the SCSI bus. This
843# means that if you removed a disk drive, you may have had to rewrite
844# your /etc/fstab file, and also that you had to be careful when adding
845# a new disk as it may have been probed earlier and moved your device
846# configuration around.
847
848# This old behavior is maintained as the default behavior. The unit
849# assignment begins with the first non-wired down unit for a device
850# type. For example, if you wire a disk as "da3" then the first
851# non-wired disk will be assigned da4.
852
853# The syntax for wiring down devices is:
854
855# device scbus0 at ahc0 # Single bus device
856# device scbus1 at ahc1 bus 0 # Single bus device
857# device scbus3 at ahc2 bus 0 # Twin bus device
858# device scbus2 at ahc2 bus 1 # Twin bus device
859# device da0 at scbus0 target 0 unit 0
860# device da1 at scbus3 target 1
861# device da2 at scbus2 target 3
862# device sa1 at scbus1 target 6
863# device cd
864
865# "units" (SCSI logical unit number) that are not specified are
866# treated as if specified as LUN 0.
867
868# All SCSI devices allocate as many units as are required.

2175# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
2176# instruments are enabled. The tools in

2178# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
2179# If you ant the driver to handle timeouts, enable
2180# this option. If your system is very busy, this
2181# option will create more trouble than solve.
