ISP(4) FreeBSD Kernel Interfaces Manual ISP(4) NAME isp -- Qlogic based SCSI and FibreChannel SCSI Host Adapters SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: device scbus device isp Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): isp_load="YES" 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 available if the ispfw(4) module is loaded during bootstrap (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 Cards supported by the isp driver include: ISP1000 SBus Fast Wide, Ultra Fast Wide cards, Single Ended or Dif- ferential cards. 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). 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 210X Qlogic 2100 and 2100A Copper and Optical Fibre Channel Arbitrated Loop (single, dual). Qlogic 220X Qlogic 2200 Copper and Optical Fibre Channel Arbitrated Loop PCI cards (single, dual, quad). Qlogic 2300 Qlogic 2300 Optical Fibre Channel PCI cards. Qlogic 2312 Qlogic 2312 Optical Fibre Channel PCI cards. Qlogic 234X Qlogic 234X Optical Fibre Channel PCI cards (2312 chipset, single and dual attach). Qlogic 2322 Qlogic 2322 Optical Fibre Channel PCI cards. Qlogic 200 Dell Branded version of the QLogic 2312 Fibre Channel PCI cards. 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 /boot/device.hints. They are: hint.isp.0.disable A hint value to disable driver in kernel. hint.isp.0.fwload_disable A hint value to disable loading of firmware ispfw(4). hint.isp.0.prefer_memmap A hint value to use PCI Memory space instead of I/O space access for. hint.isp.0.prefer_iomap A hint value to use PCI I/O space instead of Memory space access for. hint.isp.0.ignore_nvram A hint value to ignore board NVRAM settings for. Otherwise use NVRAM settings. hint.isp.0.fullduplex A hint value to set full duplex mode. hint.isp.0.topology A hint value to select topology of connection. Supported values are: lport (Prefer loopback and fallback to point to point). nport (Prefer point to point and fallback to loopback). lport-only (Loopback only). nport-only (Point to point only). 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. 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. hint.isp.0.iid A hint to override or set the Initiator ID (principally for SPI SCSI). hint.isp.0.role A hint to define default role for isp instance (target, initia- tor, both). hint.isp.0.debug A hint value for a driver debug level (values from 0 through 7). Default is 0. SEE ALSO da(4), intro(4), ispfw(4), sa(4), scsi(4) AUTHORS The isp driver was written by Matthew Jacob for NASA/Ames Research Cen- ter. BUGS The driver currently ignores some NVRAM settings. The driver currently does not do error recovery for timed out commands very gracefully. Target mode support is not completely debugged 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). 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. QLogic 2322 support is limited to platforms where the BIOS can enable firmware as there is no code yet to do the 3 stage loading for 2322 firmware. FreeBSD 6.2 February 6, 2006 FreeBSD 6.2
