following lines in your +kernel configuration file: +.Bd -ragged -offset indent +.Cd "device scbus" +.Cd "device isp" +.Ed +.Pp +Alternatively, to load the driver as a +module at boot time, place the following line in +.Xr loader.conf 5 : +.Bd -literal -offset indent +isp_load="YES" +.Ed +.Sh DESCRIPTION +This driver provides access to +.Tn SCSI +or +.Tn FibreChannel +devices. +.Pp +SCSI features include support for Ultra SCSI and wide mode transactions +for +.Tn SCSI , +Ultra2 LVD (for the ISP1080 and ISP1280), and Ultra3 LVD (for the +ISP12160). +.Pp +Fibre Channel support uses FCP SCSI profile for +.Tn FibreChannel , +and utilizes Class 3 and Class 2 connections (Qlogic 2100 is Class +3 only, minor patches to the Qlogic 2200 to force Class 2 mode). +Support is available for Public and Private loops, and for +point-to-point connections (Qlogic 2200 only). +The newer 2-Gigabit cards (2300, 2312, 2322) and 4-Gigabit (2422, 2432) +are also supported. +Command tagging is +supported for all (in fact, +.Tn FibreChannel +requires tagging). +Fabric support is enabled by default for other than 2100 cards. +Fabric +support for 2100 cards has been so problematic and these cards are so +old now that it is just not worth your time to try it. +.Sh FIRMWARE +Firmware is available if the +.Xr ispfw 4 +module is loaded during bootstrap (q.v.). +.Pp +It is +.Ar strongly +recommended that you use the firmware available +from +.Xr ispfw 4 +as it is the most likely to have been tested with this driver. +.Sh HARDWARE +Cards supported by the +.Nm +driver include: +.Bl -tag -width xxxxxx

BOOT OPTIONS +The following options are switchable by setting values in +.Pa /boot/device.hints . +.Pp +They are: +.Bl -tag -width indent +.It Va hint.isp.0.disable +A hint value to disable driver in

+access for. +.It Va hint.isp.0.prefer_iomap +A hint value to use PCI I/O space instead of Memory space +access for. +.It Va hint.isp.0.ignore_nvram +A hint value to ignore board NVRAM settings for. +Otherwise use NVRAM settings. +.It Va hint.isp.0.fullduplex +A hint value to set full duplex mode. +.It Va hint.isp.0.topology +A hint value to select topology of connection. +Supported values are: +.Pp +.Bl -tag -width ".Li lport-only" -compact +.It Li lport +Prefer loopback and fallback to point to point. +.It Li nport +Prefer point to point and fallback to loopback. +.It Li lport-only +Loopback only. +.It Li nport-only +Point to point only. +.El +.It Va hint.isp.0.portwwn +This should be the full 64 bit World Wide Port Name you would like +to use, overriding the value in NVRAM for the card. +.It Va hint.isp.0.nodewwn +This should be the full 64 bit World Wide Node Name you would like +to use, overriding the value in NVRAM for the card. +.It Va hint.isp.0.iid +A hint to override or set the Initiator ID or Loop ID. +For Fibre Channel +cards in Local Loop topologies it is +.Ar strongly +recommended that you set this value to non-zero. +.It Va hint.isp.0.role +A hint to define default role for isp instance (target, initiator, both). +.It Va hint.isp.0.debug +A hint value for a driver debug level (see the file +.Pa /usr/src/sys/dev/isp/ispvar.h +for the values. +.El +.Sh SYSCTL OPTIONS +.Bl -tag -width indent +.It Va dev.isp.N.loop_down_limit +This value says how long to wait in seconds after loop has gone down before +giving up and expiring all of the devices that were visible. +The default is 300 seconds (5 minutes). +A separate (nonadjustable) timeout is used when +booting to not stop booting on lack of FC connectivity. +.It Va dev.isp.N.gone_device_time +This value says how long to wait for devices to reappear if they (temporarily) +disappear due to loop or fabric events. +While this timeout is running, I/O +to those devices will simply be held. +.It Va dev.isp.N.wwnn +This is the readonly World Wide Node Name value for this port. +.It Va dev.isp.N.wwpn +This is the readonly World Wide Port Name value for this port. +.El +.Sh SEE ALSO +.Xr da 4 ,

+The driver currently ignores some NVRAM settings. +.Pp +Target mode support is not completely reliable yet. +It works reasonably +well for Fibre Channel, somewhat well for Qlogic 1040 cards, but +does not yet work for the other cards (due to last minute unannounced +changes in firmware interfaces). |
