Support is available for Public and Private loops, Point-to-Point and Fabric connections. .Pp Supported FC-Tape functionality is highly recommended for connections to tape drives that support it. It encompasses four elements from the T-10 FCP-4 specification: .Bl -bullet -offset indent .It Precise Delivery of Commands .It Confirmed Completion of FCP I/O Operations .It Retransmission of Unsuccessfully Transmitted IUs .It Task Retry Identification .El .Pp Together these features allow for link level error recovery with tape devices. Without it, an initiator cannot, for instance, tell whether a tape write command that has timed out resulted in all, part or none of the data going to the tape drive. FC-Tape is automatically enabled when connecting controller that supports it to a target that supports it. It may be disabled using configuration and hint options described below. .Sh FIRMWARE Firmware loading is supported and handled by .Xr firmware 9 . The correct firmware is either loaded automatically, if available for this type of adapter, or by manually loading the .Xr ispfw 4 module. It is strongly recommended that you use the firmware available from .Xr ispfw 4 as it is the one that most likely has been tested with this driver. .Sh HARDWARE Cards supported by the .Nm driver include: .Bl -tag -width xxxxxx -offset indent .It Qlogic 2422 Optical 4Gb Fibre Channel PCI-X cards. .It Qlogic 246x (aka 2432) Optical 4Gb Fibre Channel PCIe cards. .It Qlogic 256x (aka 2532) Optical 8Gb Fibre Channel PCIe cards. .It Qlogic 267x/836x (aka 2031/8031) Optical 16Gb FC/FCoE PCIe cards. .It Qlogic 2690/2692/2694 (aka 2684/2692) Optical 16Gb Fibre Channel PCIe cards. .It Qlogic 2740/2742/2764 (aka 2722/2714) Optical 32Gb Fibre Channel PCIe cards. .It Qlogic QLE2770/QLE2772 (aka 2812) Optical 32Gb Fibre Channel PCIe cards. .It Qlogic QLE2774 (aka 2814) Optical 32Gb Fibre Channel PCIe cards. .It Qlogic QLE2870/QLE2872 (aka 2812) Optical 64Gb Fibre Channel PCIe cards. .It Qlogic QLE2874 (aka 2814) Optical 64Gb Fibre Channel PCIe cards. .El .Sh CONFIGURATION OPTIONS Target mode support for Fibre Channel adapters may be enabled with the .Pp .Cd options ISP_TARGET_MODE .Pp option. .Pp To disable FC-Tape, use the following configuration option: .Pp .Cd options ISP_FCTAPE_OFF .Pp Note that even if the ISP_FCTAPE_OFF option is used, it may be overridden by the fctape hint described below. .Sh 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. Ns Ar N Ns Va .msi Limit on number of Message Signaled Interrupts (MSI) to be used. .It Va hint.isp. Ns Ar N Ns Va .msix Limit on number of Extended Message Signaled Interrupts (MSI-X) to be used. .It Va hint.isp. Ns Ar N Ns Va .fwload_disable A hint value to disable loading of firmware provided by .Xr ispfw 4 . +.It Va hint.isp. Ns Ar N Ns Va .fwload_force +A hint value to prefer firmware provided by +.Xr ispfw 4 , +even if it is older than the firmware in flash on the board. +If fwload_disable is also specified, fwload_force will be ignored. +.Pp +By default, with 27XX and newer controllers, the +.Xr isp 4 +driver will use the newer +firmware. +For older controllers, the +.Xr isp 4 +driver will use the firmware provided by +.Xr ispfw 4 +if it is available, and otherwise use the firmware in flash on the board. .It Va hint.isp. Ns Ar N Ns Va .ignore_nvram A hint value to ignore board NVRAM settings for. Otherwise use NVRAM settings. .It Va hint.isp. Ns Ar N Ns Va .fullduplex A hint value to set full duplex mode. .It Va hint.isp. Ns Ar N Ns Va .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. Ns Ar N Ns Va .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. Ns Ar N Ns Va .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. Ns Ar N Ns Va .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. Ns Ar N Ns Va .role A hint to define default role for isp instance (0 -- none, 1 -- target, 2 -- initiator, 3 -- both). .It Va hint.isp. Ns Ar N Ns Va .debug A hint value for a driver debug level (see the file .Pa /usr/src/sys/dev/isp/ispvar.h for the values. .It Va hint.isp. Ns Ar N Ns Va .vports A hint to create specified number of additional virtual ports. .It Va hint.isp. Ns Ar N Ns Va .nofctape Set this to 1 to disable FC-Tape operation on the given isp instance. .It Va hint.isp. Ns Ar N Ns Va .fctape Set this to 1 to enable FC-Tape operation on the given isp instance for targets that support it. .El .Sh SYSCTL OPTIONS .Bl -tag -width indent .It Va dev.isp. Ns Ar N Ns Va .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. Ns Ar N Ns Va .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. Ns Ar N Ns Va .use_gff_id .It Va dev.isp. Ns Ar N Ns Va .use_gft_id Setting those options to 0 allows to disable use of GFF_ID and GFT_ID SNS requests during FC fabric scan. It may be useful if switch does not implement them correctly, preventing some devices from being found. Disabling them may cause unneeded logins to ports not supporting target role or even FCP at all. The default is 1 (enabled). .It Va dev.isp. Ns Ar N Ns Va .wwnn This is the readonly World Wide Node Name value for this port. .It Va dev.isp. Ns Ar N Ns Va .wwpn This is the readonly World Wide Port Name value for this port. .It Va dev.isp. Ns Ar N Ns Va .fw_version_flash The readonly flash firmware version value in the active region of the controller. .It Va dev.isp. Ns Ar N Ns Va .fw_version_ispfw The readonly firmware version value provided by .Xr ispfw 4 . .It Va dev.isp.
