The host adapters are listed in the ISA and PCI 460# device configuration sections below. 461# 462# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 463# that a given bus, target, and LUN always come on line as the same 464# device unit. In earlier versions the unit numbers were assigned 465# in the order that the devices were probed on the SCSI bus. This 466# means that if you removed a disk drive, you may have had to rewrite 467# your /etc/fstab file, and also that you had to be careful when adding 468# a new disk as it may have been probed earlier and moved your device 469# configuration around. 470 471# This old behavior is maintained as the default behavior. The unit 472# assignment begins with the first non-wired down unit for a device 473# type. For example, if you wire a disk as "sd3" then the first 474# non-wired disk will be assigned sd4. 475 476# The syntax for wiring down devices is: 477 478# controller scbus0 at ahc0 # Single bus device 479# controller scbus1 at ahc1 bus 0 # Single bus device 480# controller scbus3 at ahc2 bus 0 # Twin bus device 481# controller scbus2 at ahc2 bus 1 # Twin bus device 482# disk sd0 at scbus0 target 0 unit 0 483# disk sd1 at scbus3 target 1 484# disk sd2 at scbus2 target 3 485# tape st1 at scbus1 target 6 486# device cd0 at scbus? 487 488# "units" (SCSI logical unit number) that are not specified are 489# treated as if specified as LUN 0. 490 491# All SCSI devices allocate as many units as are required. 492 493# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI 494# configuration and doesn't have to be explicitly configured. 495 496controller scbus0 #base SCSI code 497device ch0 #SCSI media changers 498device sd0 #SCSI disks 499device st0 #SCSI tapes 500device cd0 #SCSI CD-ROMs 501device od0 #SCSI optical disk 502 503# The previous devices (ch, sd, st, cd) are recognized by config. 504# config doesn't (and shouldn't) know about these newer ones, 505# so we have to specify that they are on a SCSI bus with the "at scbus?" 506# clause. 507 508device worm0 at scbus? # SCSI worm 509device pt0 at scbus? # SCSI processor type 510device sctarg0 at scbus? # SCSI target 511 512# SCSI OPTIONS: 513 514# SCSIDEBUG: When defined enables debugging macros 515# NO_SCSI_SENSE: When defined disables sense descriptions (about 4k) 516# SCSI_REPORT_GEOMETRY: Always report disk geometry at boot up instead 517# of only when booting verbosely. 518options SCSIDEBUG 519#options NO_SCSI_SENSE 520options SCSI_REPORT_GEOMETRY 521 522# Options for the `od' optical disk driver: 523# 524# If drive returns sense key as 0x02 with vendor specific additional 525# sense code (ASC) and additional sense code qualifier (ASCQ), or 526# illegal ASC and ASCQ.
