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 (ISP1080, ISP1280), and Ultra3 LVD (ISP12160).
65 Fibre Channel support uses FCP SCSI profile for
67 and utilizes Class 3 and Class 2 connections (Qlogic 2100 is Class
68 3 only, minor patches to the Qlogic 2200 to force Class 2 mode).
69 Support is available for Public and Private loops, and for
70 point-to-point connections (Qlogic 2200 only).
71 The newer 2-Gigabit cards (2300, 2312, 2322), 4-Gigabit (2422, 2432)
72 and 8-Gigabit (2532) are also supported.
73 Command tagging is supported for all (in fact,
76 Fabric support is enabled by default for other than 2100 cards.
77 Fabric support for 2100 cards has been so problematic and these cards are so
78 old now that it is just not worth your time to try it.
80 Firmware is available if the
82 module is loaded during bootstrap (q.v.).
86 recommended that you use the firmware available
89 as it is the most likely to have been tested with this driver.

140 .Sh CONFIGURATION OPTIONS
141 Target mode support may be enabled with the
143 .Cd options ISP_TARGET_MODE
147 The following options are switchable by setting values in
148 .Pa /boot/device.hints .
151 .Bl -tag -width indent
152 .It Va hint.isp.0.disable
153 A hint value to disable driver in kernel.
154 .It Va hint.isp.0.fwload_disable
155 A hint value to disable loading of firmware
157 .It Va hint.isp.0.prefer_memmap
158 A hint value to use PCI memory space instead of I/O space
160 .It Va hint.isp.0.prefer_iomap
161 A hint value to use PCI I/O space instead of Memory space
163 .It Va hint.isp.0.ignore_nvram
164 A hint value to ignore board NVRAM settings for.
165 Otherwise use NVRAM settings.
166 .It Va hint.isp.0.fullduplex
167 A hint value to set full duplex mode.
168 .It Va hint.isp.0.topology
169 A hint value to select topology of connection.
170 Supported values are:
172 .Bl -tag -width ".Li lport-only" -compact
174 Prefer loopback and fallback to point to point.
176 Prefer point to point and fallback to loopback.
182 .It Va hint.isp.0.portwwn
183 This should be the full 64 bit World Wide Port Name you would like
184 to use, overriding the value in NVRAM for the card.
185 .It Va hint.isp.0.nodewwn
186 This should be the full 64 bit World Wide Node Name you would like
187 to use, overriding the value in NVRAM for the card.
188 .It Va hint.isp.0.iid
189 A hint to override or set the Initiator ID or Loop ID.
191 cards in Local Loop topologies it is
193 recommended that you set this value to non-zero.
194 .It Va hint.isp.0.role
195 A hint to define default role for isp instance (target, initiator, both).
196 .It Va hint.isp.0.debug
197 A hint value for a driver debug level (see the file
198 .Pa /usr/src/sys/dev/isp/ispvar.h
200 .It Va hint.isp.0.vports
201 A hint to create specified number of additional virtual ports.
204 .Bl -tag -width indent
205 .It Va dev.isp.N.loop_down_limit
206 This value says how long to wait in seconds after loop has gone down before
207 giving up and expiring all of the devices that were visible.
208 The default is 300 seconds (5 minutes).
209 A separate (nonadjustable) timeout is used when
210 booting to not stop booting on lack of FC connectivity.
211 .It Va dev.isp.N.gone_device_time
212 This value says how long to wait for devices to reappear if they (temporarily)
213 disappear due to loop or fabric events.
214 While this timeout is running, I/O
215 to those devices will simply be held.
216 .It Va dev.isp.N.wwnn
217 This is the readonly World Wide Node Name value for this port.
218 .It Va dev.isp.N.wwpn
219 This is the readonly World Wide Port Name value for this port.
231 driver was written by
233 originally for NetBSD at NASA/Ames Research Center.
234 Some later improvement was done by
235 .An Alexander Motin Aq Mt mav@FreeBSD.org .
237 The driver currently ignores some NVRAM settings.
239 Target mode support works reasonably well for 23xx and above Fibre Channel
240 cards, but not really tested on older ones.
