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). Command tagging is
60 supported for all (in fact,
62 requires tagging). Fabric support is enabled by default (but may
63 be contingent upon the correct firmware being loaded).
65 Firmware is now available if the
67 module is loaded during bootstrap (q.v.).
69 Supported cards include:
71 .Bl -tag -width xxxxxx -offset indent
73 SBus Fast Wide, Ultra Fast Wide cards, Single Ended or Differential
76 Performance Technology ISP1000 variants.
78 Qlogic 1020 Fast Wide and Differential Fast Wide PCI cards.
80 Qlogic 1040 Ultra Wide and Differential Ultra Wide PCI cards.
82 Performance Technology ISP1040 variants.
84 Qlogic 1240 Dual Bus Ultra Wide and Differential Ultra Wide PCI
87 Qlogic 1280 LVD Ultra2 Wide PCI cards.
89 Qlogic 1280 Dual Bus LVD Ultra2 Wide PCI cards.
91 Qlogic 12160 Dual Bus LVD Ultra3 Wide PCI cards.
93 Qlogic 2100 and 2100A Copper and Optical Fibre Channel Arbitrated
96 Qlogic Dual Loop 2100A Optical Fibre Channel Arbitrated Loop PCI
99 Qlogic 2200 Copper and Optical Fibre Channel Arbitrated Loop PCI
102 Qlogic 2200 Dual Bus Optical Fibre Channel Arbitrated Loop PCI
105 Performance Technology ISP2100 variants.
107 Antares Microsystems ISP2100 variants.
109 .Sh CONFIGURATION OPTIONS
111 Target mode support may be enabled with the
113 .Cd options ISP_TARGET_MODE
117 The following options are switchable by setting values in the loader
118 configuration file (see the
120 manual page). They are:
122 .Bl -tag -width "isp_no_fwload" -compact
124 A bit mask of units to skip configuration for.
126 A bit mask of units to use PCI Memory space instead of I/O space
129 A bit mask of units to use PCI I/O space instead of Memory space
132 A bit mask of units that you wish to ignore board NVRAM settings
135 A bit mask of units that you wish to specifically use board NVRAM
138 A bit mask of units that you wish to specifically to set into full
141 A bit mask of units that you wish to specifically to not set into
144 This should be the full 64 bit World Wide Node Name you would like
145 to use, overriding the value in NVRAM for the card.
147 This is a driver debug level- meaningful from 0 through 7.
149 This is a driver target mode debug level- meaningful from 0 through
153 The driver currently ignores some NVRAM settings.
155 The driver currently doesn't do error recovery for timed out commands
158 Target mode support isn't completely debugged yet. It works reasonably
159 well for Fibre Channel, somewhat well for Qlogic 1040 cards, but
160 doesn't yet work for the other cards (due to last minute unnanounced
161 changes in firmware interfaces).
163 Sometimes, when booting, the driver gets stuck waiting for the
164 Fibre Channel f/w to tell it that the loop port database is ready,
165 or waiting for a good loop to be seen (this does not yet support
166 booting without being connected to a fibre channel device). To
167 unwedge the system, unplug and replug the fibre channel connection,
168 or otherwise cause a LIP (Loop Initialization Primitive sequence)-
169 this will kick the f/w into getting unstuck.
