ISP(4) FreeBSD Kernel Interfaces Manual ISP(4) NAME isp -- Qlogic based SCSI and FibreChannel SCSI Host Adapters SYNOPSIS device isp For one or more SCSI busses: device scbus0 DESCRIPTION This driver provides access to SCSI or FibreChannel devices. SCSI features include support for Ultra SCSI and wide mode transactions for SCSI, Ultra2 LVD (for the ISP1080 and ISP1280), and Ultra3 LVD (for the ISP12160). Fibre Channel support uses FCP SCSI profile for FibreChannel. and uti- lizes 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) are also supported. Command tagging is supported for all (in fact, FibreChannel requires tag- ging). Fabric support is enabled by default (but may be contingent upon the correct firmware being loaded). FIRMWARE Firmware is now available if the ispfw(4) module is loaded during boot- strap (q.v.). It is very strongly recommended that you use the firmware available from ispfw(4) as it is the most likely to have been tested with this driver. HARDWARE Supported cards include: ISP1000 SBus Fast Wide, Ultra Fast Wide cards, Single Ended or Dif- ferential cards. PTI SBS440 Performance Technology ISP1000 variants. ISP1020 Qlogic 1020 Fast Wide and Differential Fast Wide PCI cards. ISP1040 Qlogic 1040 Ultra Wide and Differential Ultra Wide PCI cards. Also known as the DEC KZPBA-CA (single ended) and KZPBA-CB (HVD differential). PTI SBS450 Performance Technology ISP1040 variants. Qlogic 1240 Qlogic 1240 Dual Bus Ultra Wide and Differential Ultra Wide PCI cards. Qlogic 1020 Qlogic 1020 SCSI cards. Qlogic 1040 Qlogic 1040 Ultra SCSI cards. Qlogic 1080 Qlogic 1280 LVD Ultra2 Wide PCI cards. Qlogic 1280 Qlogic 1280 Dual Bus LVD Ultra2 Wide PCI cards. Qlogic 12160 Qlogic 12160 Dual Bus LVD Ultra3 Wide PCI cards. Qlogic 2100 Qlogic 2100 and 2100A Copper and Optical Fibre Channel Arbitrated Loop Qlogic 2102 Qlogic Dual Loop 2100A Optical Fibre Channel Arbitrated Loop PCI cards. Qlogic 2200 Qlogic 2200 Copper and Optical Fibre Channel Arbitrated Loop PCI cards. Qlogic 2202 Qlogic 2200 Dual Bus Optical Fibre Channel Arbitrated Loop PCI cards. Qlogic 2300 Qlogic 2300 Optical Fibre Channel PCI cards. Qlogic 2312 Qlogic 2312 Optical Fibre Channel PCI cards. PTI SBS470 Performance Technology ISP2100 variants. Antares P-0033 Antares Microsystems ISP2100 variants. CONFIGURATION OPTIONS Target mode support may be enabled with the options ISP_TARGET_MODE option. BOOT OPTIONS The following options are switchable by setting values in the loader con- figuration file (see the loader(8) manual page). They are: isp_disable A bit mask of units to skip configuration for. isp_mem_map A bit mask of units to use PCI Memory space instead of I/O space access for. isp_io_map A bit mask of units to use PCI I/O space instead of Memory space access for. isp_no_nvram A bit mask of units that you wish to ignore board NVRAM settings for. isp_nvram A bit mask of units that you wish to specifically use board NVRAM settings for. isp_fcduplex A bit mask of units that you wish to specifically to set into full duplex mode. isp_no_fcduplex A bit mask of units that you wish to specifically to not set into full duplex mode. isp_wwn This should be the full 64 bit World Wide Node Name you would like to use, overriding the value in NVRAM for the card. isp_debug This is a driver debug level- meaningful from 0 through 7. isp_tdebug This is a driver target mode debug level- meaningful from 0 through 5. BUGS The driver currently ignores some NVRAM settings. The driver currently doesn't do error recovery for timed out commands very gracefully. Target mode support isn't completely debugged yet. It works reasonably well for Fibre Channel, somewhat well for Qlogic 1040 cards, but doesn't yet work for the other cards (due to last minute unannounced changes in firmware interfaces). Sometimes, when booting, the driver gets stuck waiting for the Fibre Channel f/w to tell it that the loop port database is ready, or waiting for a good loop to be seen (this does not yet support booting without being connected to a fibre channel device). To unwedge the system, unplug and replug the fibre channel connection, or otherwise cause a LIP (Loop Initialization Primitive sequence)- this will kick the f/w into getting unstuck.
