36.Nd Qlogic based SCSI and FibreChannel SCSI Host Adapters 37.Sh SYNOPSIS 38.Cd "device isp" 39.Pp 40For one or more SCSI busses: 41.Cd device scbus0 42.Sh DESCRIPTION 43This driver provides access to 44.Tn SCSI 45or 46.Tn FibreChannel 47devices. 48.Pp 49SCSI features include support for Ultra SCSI and wide mode transactions 50for 51.Tn SCSI , 52Ultra2 LVD (for the ISP1080 and ISP1280), and Ultra3 LVD (for the 53ISP12160). 54.Pp 55Fibre Channel support uses FCP SCSI profile for 56.Tn FibreChannel . 57and utilizes Class 3 and Class 2 connections (Qlogic 2100 is Class 583 only, minor patches to the Qlogic 2200 to force Class 2 mode). 59Support is available for Public and Private loops, and for 60point-to-point connections (Qlogic 2200 only). 61The newer 2-Gigabit cards (2300, 2312) are also supported. 62Command tagging is 63supported for all (in fact, 64.Tn FibreChannel 65requires tagging). 66Fabric support is enabled by default (but may 67be contingent upon the correct firmware being loaded). 68.Sh FIRMWARE 69Firmware is now available if the 70.Xr ispfw 4 71module is loaded during bootstrap (q.v.). 72.Pp 73It is very strongly recommended that you use the firmware available 74from 75.Xr ispfw 4 76as it is the most likely to have been tested with this driver. 77.Sh HARDWARE 78Supported cards include: 79.Bl -tag -width xxxxxx -offset indent 80.It ISP1000 81SBus

ISP_TARGET_MODE 125.Pp 126option. 127.Sh BOOT OPTIONS 128The following options are switchable by setting values in the loader 129configuration file (see the 130.Xr loader 8 131manual page). 132They

172.Nm 173driver was written by Matthew Jacob for NASA/Ames Research Center. 174.Sh BUGS 175The driver currently ignores some NVRAM settings. 176.Pp 177The driver currently doesn't do error recovery for timed out commands 178very gracefully. 179.Pp 180Target mode support isn't completely debugged yet. 181It works reasonably 182well for Fibre Channel, somewhat well for Qlogic 1040 cards, but 183doesn't yet work for the other cards (due to last minute unannounced 184changes in firmware interfaces). 185.Pp 186Sometimes, when booting, the driver gets stuck waiting for the 187Fibre Channel f/w to tell it that the loop port database is ready, 188or waiting for a good loop to be seen (this does not yet support 189booting without being connected to a fibre channel device). 190To 191unwedge the system, unplug and replug the fibre channel connection, 192or otherwise cause a LIP (Loop Initialization Primitive sequence)- 193this will kick the f/w into getting unstuck. 194
