35 .Nd Qlogic based SCSI and FibreChannel SCSI Host Adapters
39 For one or more SCSI busses:
42 This driver provides access to
48 SCSI features include support for Ultra SCSI and wide mode transactions
51 Ultra2 LVD (for the ISP1080 and ISP1280), and Ultra3 LVD (for the
54 Fibre Channel support uses FCP SCSI profile for
56 and utilizes Class 3 and Class 2 connections (Qlogic 2100 is Class
57 3 only, minor patches to the Qlogic 2200 to force Class 2 mode).
58 Support is available for Public and Private loops, and for
59 point-to-point connections (Qlogic 2200 only).
60 The newer 2-Gigabit cards (2300, 2312) are also supported.
62 supported for all (in fact,
65 Fabric support is enabled by default (but may
66 be contingent upon the correct firmware being loaded).
68 Firmware is now available if the
70 module is loaded during bootstrap (q.v.).
72 It is very strongly recommended that you use the firmware available
75 as it is the most likely to have been tested with this driver.

131 .Sh CONFIGURATION OPTIONS
133 Target mode support may be enabled with the
135 .Cd options ISP_TARGET_MODE
139 The following options are switchable by setting values in the loader
140 configuration file (see the
145 .Bl -tag -width "isp_no_fwload" -compact
147 A bit mask of units to skip configuration for.
149 A bit mask of units to use PCI Memory space instead of I/O space
152 A bit mask of units to use PCI I/O space instead of Memory space
155 A bit mask of units that you wish to ignore board NVRAM settings
158 A bit mask of units that you wish to specifically use board NVRAM
161 A bit mask of units that you wish to specifically to set into full
164 A bit mask of units that you wish to specifically to not set into
167 This should be the full 64 bit World Wide Node Name you would like
168 to use, overriding the value in NVRAM for the card.
170 This is a driver debug level- meaningful from 0 through 7.
172 This is a driver target mode debug level- meaningful from 0 through
184 driver was written by Matthew Jacob for NASA/Ames Research Center.
186 The driver currently ignores some NVRAM settings.
188 The driver currently does not do error recovery for timed out commands
191 Target mode support is not completely debugged yet.
193 well for Fibre Channel, somewhat well for Qlogic 1040 cards, but
194 does not yet work for the other cards (due to last minute unannounced
195 changes in firmware interfaces).
197 Sometimes, when booting, the driver gets stuck waiting for the
198 Fibre Channel f/w to tell it that the loop port database is ready,
199 or waiting for a good loop to be seen (this does not yet support
200 booting without being connected to a fibre channel device).
202 unwedge the system, unplug and replug the fibre channel connection,
203 or otherwise cause a LIP (Loop Initialization Primitive sequence)-
204 this will kick the f/w into getting unstuck.
