31.Dt ISP 4
32.Os
33.Sh NAME
34.Nm isp
35.Nd Qlogic based SCSI and FibreChannel SCSI Host Adapters
36.Sh SYNOPSIS
37.Cd "device isp"
38.Pp
39For one or more SCSI busses:
40.Cd device scbus0
41.Sh DESCRIPTION
42This driver provides access to
43.Tn SCSI
44or
45.Tn FibreChannel
46devices.
47.Pp
48SCSI features include support for Ultra SCSI and wide mode transactions
49for
50.Tn SCSI ,
51Ultra2 LVD (for the ISP1080 and ISP1280), and Ultra3 LVD (for the
52ISP12160).
53.Pp
54Fibre Channel support uses FCP SCSI profile for
55.Tn FibreChannel .
56and utilizes Class 3 and Class 2 connections (Qlogic 2100 is Class
573 only, minor patches to the Qlogic 2200 to force Class 2 mode).
58Support is available for Public and Private loops, and for
59point-to-point connections (Qlogic 2200 only).
60The newer 2-Gigabit cards (2300, 2312) are also supported.
61Command tagging is
62supported for all (in fact,
63.Tn FibreChannel
64requires tagging).
65Fabric support is enabled by default (but may
66be contingent upon the correct firmware being loaded).
67.Sh FIRMWARE
68Firmware is now available if the
69.Xr ispfw 4
70module is loaded during bootstrap (q.v.).
71.Pp
72It is very strongly recommended that you use the firmware available
73from
74.Xr ispfw 4
75as it is the most likely to have been tested with this driver.
76.Sh HARDWARE
77Supported cards include:
78.Pp

125.Sh CONFIGURATION OPTIONS
126.Pp
127Target mode support may be enabled with the
128.Pp
129.Cd options ISP_TARGET_MODE
130.Pp
131option.
132.Sh BOOT OPTIONS
133The following options are switchable by setting values in the loader
134configuration file (see the
135.Xr loader 8
136manual page).
137They are:
138.Pp
139.Bl -tag -width "isp_no_fwload" -compact
140.It isp_disable
141A bit mask of units to skip configuration for.
142.It isp_mem_map
143A bit mask of units to use PCI Memory space instead of I/O space
144access for.
145.It isp_io_map
146A bit mask of units to use PCI I/O space instead of Memory space
147access for.
148.It isp_no_nvram
149A bit mask of units that you wish to ignore board NVRAM settings
150for.
151.It isp_nvram
152A bit mask of units that you wish to specifically use board NVRAM
153settings for.
154.It isp_fcduplex
155A bit mask of units that you wish to specifically to set into full
156duplex mode.
157.It isp_no_fcduplex
158A bit mask of units that you wish to specifically to not set into
159full duplex mode.
160.It isp_wwn
161This should be the full 64 bit World Wide Node Name you would like
162to use, overriding the value in NVRAM for the card.
163.It isp_debug
164This is a driver debug level- meaningful from 0 through 7.
165.It isp_tdebug
166This is a driver target mode debug level- meaningful from 0 through
1675.
168.El
169.Sh BUGS
170The driver currently ignores some NVRAM settings.
171.Pp
172The driver currently doesn't do error recovery for timed out commands
173very gracefully.
174.Pp
175Target mode support isn't completely debugged yet.
176It works reasonably
177well for Fibre Channel, somewhat well for Qlogic 1040 cards, but
178doesn't yet work for the other cards (due to last minute unannounced
179changes in firmware interfaces).
180.Pp
181Sometimes, when booting, the driver gets stuck waiting for the
182Fibre Channel f/w to tell it that the loop port database is ready,
183or waiting for a good loop to be seen (this does not yet support
184booting without being connected to a fibre channel device).
185To
186unwedge the system, unplug and replug the fibre channel connection,
187or otherwise cause a LIP (Loop Initialization Primitive sequence)-
188this will kick the f/w into getting unstuck.
