The host adapters are listed in the ISA and PCI 1213# device configuration sections below. 1214# 1215# It is possible to wire down your SCSI devices so that a given bus, 1216# target, and LUN always come on line as the same device unit. In 1217# earlier versions the unit numbers were assigned in the order that 1218# the devices were probed on the SCSI bus. This means that if you 1219# removed a disk drive, you may have had to rewrite your /etc/fstab 1220# file, and also that you had to be careful when adding a new disk 1221# as it may have been probed earlier and moved your device configuration 1222# around. (See also option GEOM_VOL for a different solution to this 1223# problem.) 1224 1225# This old behavior is maintained as the default behavior. The unit 1226# assignment begins with the first non-wired down unit for a device 1227# type. For example, if you wire a disk as "da3" then the first 1228# non-wired disk will be assigned da4. 1229 1230# The syntax for wiring down devices is: 1231 1232hint.scbus.0.at="ahc0" 1233hint.scbus.1.at="ahc1" 1234hint.scbus.1.bus="0" 1235hint.scbus.3.at="ahc2" 1236hint.scbus.3.bus="0" 1237hint.scbus.2.at="ahc2" 1238hint.scbus.2.bus="1" 1239hint.da.0.at="scbus0" 1240hint.da.0.target="0" 1241hint.da.0.unit="0" 1242hint.da.1.at="scbus3" 1243hint.da.1.target="1" 1244hint.da.2.at="scbus2" 1245hint.da.2.target="3" 1246hint.sa.1.at="scbus1" 1247hint.sa.1.target="6" 1248 1249# "units" (SCSI logical unit number) that are not specified are 1250# treated as if specified as LUN 0. 1251 1252# All SCSI devices allocate as many units as are required. 1253 1254# The ch driver drives SCSI Media Changer ("jukebox") devices. 1255# 1256# The da driver drives SCSI Direct Access ("disk") and Optical Media 1257# ("WORM") devices. 1258# 1259# The sa driver drives SCSI Sequential Access ("tape") devices. 1260# 1261# The cd driver drives SCSI Read Only Direct Access ("cd") devices. 1262# 1263# The ses driver drives SCSI Environment Services ("ses") and 1264# SAF-TE ("SCSI Accessible Fault-Tolerant Enclosure") devices. 1265# 1266# The pt driver drives SCSI Processor devices. 1267# 1268# The sg driver provides a passthrough API that is compatible with the 1269# Linux SG driver.
