Pq PCI 38.Cd "isp* at sbus? slot ? offset ?" Pq SBus 39.Cd scsibus* at isp? 40.Sh DESCRIPTION 41This driver provides access to 42.Tn SCSI 43or 44.Tn FibreChannel 45devices. 46.Pp 47SCSI features include support for Ultra SCSI and wide mode transactions for 48.Tn SCSI , 49and LVD (for the ISP1080 and ISP1280), 50.Pp 51Fibre Channel support uses FCP SCSI profile for 52.Tn FibreChannel . 53and utilizes Class 3 connections only. Support is available for Public 54and Private loops. 55Command tagging is supported for all (in fact, 56.Tn FibreChannel 57requires tagging). 58.Sh CONFIGURATION 59An optional 60.Tn flags 0x80 61appended to the above 62.Tn isp* 63declarations will disable the download of driver f/w, which means you 64use whatever F/W is running on the card. If no firmware is running on the card, 65the driver cannot operate the card. 66.Pp 67An optional 68.Tn flags 0x40 69appended to the above 70.Tn isp* 71declarations (can be OR'd in with the other config flags option) 72will keep the driver from looking at device or bus NVRAM settings (this 73is in case NVRAM is just wrong and you have the card in a platform where 74it is inconvenient to change NVRAM settings on the card). 75.Sh HARDWARE 76Supported cards include: 77.Pp 78.Bl -tag -width xxxxxx -offset indent 79.It ISP1000 80SBus Fast Wide, Ultra Fast Wide cards, Single Ended or Differential cards. 81.It PTI SBS440 82Performance Technology ISP1000 variants. 83.It ISP1020 84Qlogic 1020 Fast Wide and Differential Fast Wide PCI cards. 85.It ISP1040 86Qlogic 1040 Ultra Wide and Differential Ultra Wide PCI cards. 87.It PTI SBS450 88Performance Technology ISP1040 variants. 89.It Qlogic 1240 90Qlogic 1240 Dual Bus Ultra Wide and Differential Ultra Wide PCI cards. 91.It Qlogic 1080 92Qlogic 1280 LVD Ultra2 Wide PCI cards. 93.It Qlogic 1280 94Qlogic 1280 Dual Bus LVD Ultra2 Wide PCI cards. 95.It Qlogic 2100 96Qlogic 2100 and 2100A Copper and Optical Fibre Channel Arbitrated Loop 97.It Qlogic 2102 98Qlogic Dual Loop 2100A Optical Fibre Channel Arbitrated Loop PCI cards. 99.It Qlogic 2200 100Qlogic 2200 Copper and Optical Fibre Channel Arbitrated Loop PCI cards. 101.It Qlogic 2202 102Qlogic 2200 Dual Bus Optical Fibre Channel Arbitrated Loop PCI cards. 103.It Qlogic 2204 104Qlogic 2200 Quad Bus Optical Fibre Channel Arbitrated Loop PCI cards. 105.It Qlogic 2300 106Qlogic 2300 2-Gigabit Optical Fibre Channel PCI cards. 107.It Qlogic 2312 108Qlogic 2300 2-Gigabit Dual Channel Optical Fibre Channel PCI cards. 109.It PTI SBS470 110Performance Technology ISP2100 variants. 111.It Antares P-0033 112Antares Microsystems ISP2100 variants. 113.El 114.Sh SEE ALSO 115.Xr cd 4 , 116.Xr intro 4 , 117.Xr scsi 4 , 118.Xr sd 4 , 119.Xr st 4 120.Sh AUTHORS 121The 122.Nm 123driver was written by Matthew Jacob for NASA/Ames Research Center. 124.Sh BUGS 125The driver currently ignores some NVRAM settings. 126.Pp 127The driver currently doesn't do error recovery for timed out commands 128very gracefully. 129.Pp 130Sometimes, when booting, the driver gets stuck waiting for the Fibre Channel 131f/w to tell it that the loop port database is ready. In this case you'll 132see an announcement that the loop state has a value of 0x1. To unwedge 133the system, unplug and replug the fibre channel connection, or otherwise 134cause a LIP (Loop Initialization Primitive sequence)- this will kick the f/w 135into getting unstuck. 136
