37 .Nd Qlogic based SCSI and FibreChannel SCSI Host Adapters
39 To compile this driver into the kernel,
40 place the following lines in your
41 kernel configuration file:
42 .Bd -ragged -offset indent
47 Alternatively, to load the driver as a
48 module at boot time, place the following line in
50 .Bd -literal -offset indent
54 This driver provides access to
60 SCSI features include support for Ultra SCSI and wide mode transactions
63 Ultra2 LVD (for the ISP1080 and ISP1280), and Ultra3 LVD (for the
66 Fibre Channel support uses FCP SCSI profile for
68 and utilizes Class 3 and Class 2 connections (Qlogic 2100 is Class
69 3 only, minor patches to the Qlogic 2200 to force Class 2 mode).
70 Support is available for Public and Private loops, and for
71 point-to-point connections (Qlogic 2200 only).
72 The newer 2-Gigabit cards (2300, 2312, 2322) and 4-Gigabit (2422, 2432)
75 supported for all (in fact,
78 Fabric support is enabled by default for other than 2100 cards.
80 support for 2100 cards has been so problematic and these cards are so
81 old now that it is just not worth your time to try it.
83 Firmware is available if the
85 module is loaded during bootstrap (q.v.).
89 recommended that you use the firmware available
92 as it is the most likely to have been tested with this driver.

140 .Sh CONFIGURATION OPTIONS
142 Target mode support may be enabled with the
144 .Cd options ISP_TARGET_MODE
148 The following options are switchable by setting values in
149 .Pa /boot/device.hints .
152 .Bl -tag -width indent
153 .It Va hint.isp.0.disable
154 A hint value to disable driver in kernel.
155 .It Va hint.isp.0.fwload_disable
156 A hint value to disable loading of firmware
158 .It Va hint.isp.0.prefer_memmap
159 A hint value to use PCI memory space instead of I/O space
161 .It Va hint.isp.0.prefer_iomap
162 A hint value to use PCI I/O space instead of Memory space
164 .It Va hint.isp.0.ignore_nvram
165 A hint value to ignore board NVRAM settings for.
166 Otherwise use NVRAM settings.
167 .It Va hint.isp.0.fullduplex
168 A hint value to set full duplex mode.
169 .It Va hint.isp.0.topology
170 A hint value to select topology of connection.
171 Supported values are:
173 .Bl -tag -width ".Li lport-only" -compact
175 Prefer loopback and fallback to point to point.
177 Prefer point to point and fallback to loopback.
183 .It Va hint.isp.0.portwwn
184 This should be the full 64 bit World Wide Port Name you would like
185 to use, overriding the value in NVRAM for the card.
186 .It Va hint.isp.0.nodewwn
187 This should be the full 64 bit World Wide Node Name you would like
188 to use, overriding the value in NVRAM for the card.
189 .It Va hint.isp.0.iid
190 A hint to override or set the Initiator ID or Loop ID.
192 cards in Local Loop topologies it is
194 recommended that you set this value to non-zero.
195 .It Va hint.isp.0.role
196 A hint to define default role for isp instance (target, initiator, both).
197 .It Va hint.isp.0.debug
198 A hint value for a driver debug level (see the file
199 .Pa /usr/src/sys/dev/isp/ispvar.h
203 .Bl -tag -width indent
204 .It Va dev.isp.N.loop_down_limit
205 This value says how long to wait in seconds after loop has gone down before
206 giving up and expiring all of the devices that were visible.
207 The default is 300 seconds (5 minutes).
208 A separate (nonadjustable) timeout is used when
209 booting to not stop booting on lack of FC connectivity.
210 .It Va dev.isp.N.gone_device_time
211 This value says how long to wait for devices to reappear if they (temporarily)
212 disappear due to loop or fabric events.
213 While this timeout is running, I/O
214 to those devices will simply be held.
215 .It Va dev.isp.N.wwnn
216 This is the readonly World Wide Node Name value for this port.
217 .It Va dev.isp.N.wwpn
218 This is the readonly World Wide Port Name value for this port.
230 driver was written by Matthew Jacob originally for NetBSD at
231 NASA/Ames Research Center.
233 The driver currently ignores some NVRAM settings.
235 Target mode support is not completely reliable yet.
237 well for Fibre Channel, somewhat well for Qlogic 1040 cards, but
238 does not yet work for the other cards (due to last minute unannounced
239 changes in firmware interfaces).
