40place the following lines in your 41kernel configuration file: 42.Bd -ragged -offset indent 43.Cd "device scbus" 44.Cd "device isp" 45.Ed 46.Pp 47Alternatively, to load the driver as a 48module at boot time, place the following line in 49.Xr loader.conf 5 : 50.Bd -literal -offset indent 51isp_load="YES" 52.Ed 53.Sh DESCRIPTION 54This driver provides access to 55.Tn SCSI 56or 57.Tn FibreChannel 58devices. 59.Pp 60SCSI features include support for Ultra SCSI and wide mode transactions 61for 62.Tn SCSI , 63Ultra2 LVD (for the ISP1080 and ISP1280), and Ultra3 LVD (for the 64ISP12160). 65.Pp 66Fibre Channel support uses FCP SCSI profile for 67.Tn FibreChannel , 68and utilizes Class 3 and Class 2 connections (Qlogic 2100 is Class 693 only, minor patches to the Qlogic 2200 to force Class 2 mode). 70Support is available for Public and Private loops, and for 71point-to-point connections (Qlogic 2200 only). 72The newer 2-Gigabit cards (2300, 2312, 2322) and 4-Gigabit (2422, 2432) 73are also supported. 74Command tagging is 75supported for all (in fact, 76.Tn FibreChannel 77requires tagging). 78Fabric support is enabled by default for other than 2100 cards. 79Fabric 80support for 2100 cards has been so problematic and these cards are so 81old now that it is just not worth your time to try it. 82.Sh FIRMWARE 83Firmware is available if the 84.Xr ispfw 4 85module is loaded during bootstrap (q.v.). 86.Pp 87It is 88.Ar strongly 89recommended that you use the firmware available 90from 91.Xr ispfw 4 92as it is the most likely to have been tested with this driver. 93.Sh HARDWARE 94Cards supported by the 95.Nm 96driver include: 97.Bl -tag -width xxxxxx -offset indent 98.It ISP1000 99SBus Fast Wide, Ultra Fast Wide cards, Single Ended or Differential 100cards. 101.It ISP1020

switchable by setting values in 148.Pa /boot/device.hints . 149.Pp 150They are: 151.Bl -tag -width indent 152.It Va hint.isp.0.disable 153A hint value to disable driver in kernel. 154.It Va hint.isp.0.fwload_disable 155A hint value to disable loading of firmware 156.Xr ispfw 4 . 157.It Va hint.isp.0.prefer_memmap 158A hint value to use PCI memory space instead of I/O space 159access for. 160.It Va hint.isp.0.prefer_iomap 161A hint value to use PCI I/O space instead of Memory space 162access for. 163.It Va hint.isp.0.ignore_nvram 164A hint value to ignore board NVRAM settings for. 165Otherwise use NVRAM settings. 166.It Va hint.isp.0.fullduplex 167A hint value to set full duplex mode. 168.It Va hint.isp.0.topology 169A hint value to select topology of connection. 170Supported values are: 171.Pp 172.Bl -tag -width ".Li lport-only" -compact 173.It Li lport 174Prefer loopback and fallback to point to point. 175.It Li nport 176Prefer point to point and fallback to loopback. 177.It Li lport-only 178Loopback only. 179.It Li nport-only 180Point to point only. 181.El 182.It Va hint.isp.0.portwwn 183This should be the full 64 bit World Wide Port Name you would like 184to use, overriding the value in NVRAM for the card. 185.It Va hint.isp.0.nodewwn 186This should be the full 64 bit World Wide Node Name you would like 187to use, overriding the value in NVRAM for the card. 188.It Va hint.isp.0.iid 189A hint to override or set the Initiator ID or Loop ID. 190For Fibre Channel 191cards in Local Loop topologies it is 192.Ar strongly 193recommended that you set this value to non-zero. 194.It Va hint.isp.0.role 195A hint to define default role for isp instance (target, initiator, both). 196.It Va hint.isp.0.debug 197A hint value for a driver debug level (see the file 198.Pa /usr/src/sys/dev/isp/ispvar.h 199for the values. 200.El 201.Sh SYSCTL OPTIONS 202.Bl -tag -width indent 203.It Va dev.isp.N.loop_down_limit 204This value says how long to wait in seconds after loop has gone down before 205giving up and expiring all of the devices that were visible. 206The default is 300 seconds (5 minutes). 207A separate (nonadjustable) timeout is used when 208booting to not stop booting on lack of FC connectivity. 209.It Va dev.isp.N.gone_device_time 210This value says how long to wait for devices to reappear if they (temporarily) 211disappear due to loop or fabric events. 212While this timeout is running, I/O 213to those devices will simply be held. 214.It Va dev.isp.N.wwnn 215This is the readonly World Wide Node Name value for this port. 216.It Va dev.isp.N.wwpn 217This is the readonly World Wide Port Name value for this port. 218.El 219.Sh SEE ALSO 220.Xr da 4 , 221.Xr intro 4 , 222.Xr ispfw 4 , 223.Xr sa 4 , 224.Xr scsi 4 , 225.Xr gmultipath

234Target mode support is not completely reliable yet. 235It works reasonably 236well for Fibre Channel, somewhat well for Qlogic 1040 cards, but 237does not yet work for the other cards (due to last minute unannounced 238changes in firmware interfaces).
