32 .Nd Qlogic FibreChannel SCSI Host Adapters driver
34 To compile this driver into the kernel,
35 place the following lines in your
36 kernel configuration file:
37 .Bd -ragged -offset indent
43 Alternatively, to load the driver as a
44 module at boot time, place the following lines in
46 .Bd -literal -offset indent
51 This driver provides access to
55 It supports initiator and target modes of FCP SCSI profile,
56 utilizing Class 3 and Class 2 connections.
57 Support is available for Public and Private loops, Point-to-Point
58 and Fabric connections.
60 Supported FC-Tape functionality is highly recommended for connections
61 to tape drives that support it.
62 It encompasses four elements from the T-10 FCP-4 specification:
63 .Bl -bullet -offset indent
65 Precise Delivery of Commands
67 Confirmed Completion of FCP I/O Operations
69 Retransmission of Unsuccessfully Transmitted IUs
71 Task Retry Identification
74 Together these features allow for link level error recovery with tape
76 Without it, an initiator cannot, for instance, tell whether a tape write
77 command that has timed out resulted in all, part or none of the data going to
79 FC-Tape is automatically enabled when connecting controller that supports
80 it to a target that supports it.
81 It may be disabled using configuration and hint options described below.
83 Firmware loading is supported if the
86 It is strongly recommended that you use the firmware available from
88 as it is the most likely to have been tested with this driver.

115 .Sh CONFIGURATION OPTIONS
116 Target mode support for Fibre Channel adapters may be enabled with the
118 .Cd options ISP_TARGET_MODE
122 To disable FC-Tape, use the following configuration option:
124 .Cd options ISP_FCTAPE_OFF
126 Note that even if the ISP_FCTAPE_OFF option is used, it may be overridden
127 by the fctape hint described below.
129 The following options are switchable by setting values in
130 .Pa /boot/device.hints .
133 .Bl -tag -width indent
134 .It Va hint.isp. Ns Ar N Ns Va .msi
135 Limit on number of Message Signaled Interrupts (MSI) to be used.
136 .It Va hint.isp. Ns Ar N Ns Va .msix
137 Limit on number of Extended Message Signaled Interrupts (MSI-X) to be used.
138 .It Va hint.isp. Ns Ar N Ns Va .fwload_disable
139 A hint value to disable loading of firmware
141 .It Va hint.isp. Ns Ar N Ns Va .ignore_nvram
142 A hint value to ignore board NVRAM settings for.
143 Otherwise use NVRAM settings.
144 .It Va hint.isp. Ns Ar N Ns Va .fullduplex
145 A hint value to set full duplex mode.
146 .It Va hint.isp. Ns Ar N Ns Va .topology
147 A hint value to select topology of connection.
148 Supported values are:
150 .Bl -tag -width ".Li lport-only" -compact
152 Prefer loopback and fallback to point to point.
154 Prefer point to point and fallback to loopback.
160 .It Va hint.isp. Ns Ar N Ns Va .portwwn
161 This should be the full 64 bit World Wide Port Name you would like
162 to use, overriding the value in NVRAM for the card.
163 .It Va hint.isp. Ns Ar N Ns Va .nodewwn
164 This should be the full 64 bit World Wide Node Name you would like
165 to use, overriding the value in NVRAM for the card.
166 .It Va hint.isp. Ns Ar N Ns Va .iid
167 A hint to override or set the Initiator ID or Loop ID.
169 cards in Local Loop topologies it is
171 recommended that you set this value to non-zero.
172 .It Va hint.isp. Ns Ar N Ns Va .role
173 A hint to define default role for isp instance (0 -- none, 1 -- target,
174 2 -- initiator, 3 -- both).
175 .It Va hint.isp. Ns Ar N Ns Va .debug
176 A hint value for a driver debug level (see the file
177 .Pa /usr/src/sys/dev/isp/ispvar.h
179 .It Va hint.isp. Ns Ar N Ns Va .vports
180 A hint to create specified number of additional virtual ports.
181 .It Va hint.isp. Ns Ar N Ns Va .nofctape
182 Set this to 1 to disable FC-Tape operation on the given isp instance.
183 .It Va hint.isp. Ns Ar N Ns Va .fctape
184 Set this to 1 to enable FC-Tape operation on the given isp instance for
185 targets that support it.
188 .Bl -tag -width indent
189 .It Va dev.isp. Ns Ar N Ns Va .loop_down_limit
190 This value says how long to wait in seconds after loop has gone down before
191 giving up and expiring all of the devices that were visible.
192 The default is 300 seconds (5 minutes).
193 A separate (nonadjustable) timeout is used when
194 booting to not stop booting on lack of FC connectivity.
195 .It Va dev.isp. Ns Ar N Ns Va .gone_device_time
196 This value says how long to wait for devices to reappear if they (temporarily)
197 disappear due to loop or fabric events.
198 While this timeout is running, I/O
199 to those devices will simply be held.
200 .It Va dev.isp. Ns Ar N Ns Va .use_gff_id
201 .It Va dev.isp. Ns Ar N Ns Va .use_gft_id
202 Setting those options to 0 allows to disable use of GFF_ID and GFT_ID SNS
203 requests during FC fabric scan.
204 It may be useful if switch does not implement them correctly,
205 preventing some devices from being found.
206 Disabling them may cause unneeded logins to ports not supporting target role
208 The default is 1 (enabled).
209 .It Va dev.isp. Ns Ar N Ns Va .wwnn
210 This is the readonly World Wide Node Name value for this port.
211 .It Va dev.isp. Ns Ar N Ns Va .wwpn
212 This is the readonly World Wide Port Name value for this port.
224 driver was written by
226 originally for NetBSD at NASA/Ames Research Center.
227 Later improvement was done by
