ISP(4) Device Drivers Manual ISP(4)

isp — Qlogic based SPI and FibreChannel SCSI Host Adapters

To compile this driver into the kernel, place the following lines in your kernel configuration file:

device scbus
device isp
device ispfw

Alternatively, to load the driver as a module at boot time, place the following lines in loader.conf(5):

isp_load="YES"
ispfw_load="YES"

This driver provides access to SPI or FibreChannel SCSI devices.

SPI supports initiator mode for Ultra SCSI and wide mode transactions for SCSI, Ultra2 LVD (1080, 1280), and Ultra3 LVD (10160, 12160).

Fibre Channel supports initiator and target modes of FCP SCSI profile, utilizing Class 3 and Class 2 (2200 and later) connections. Support is available for Public and Private loops, Point-to-Point and Fabric connections.

FC-Tape is supported on 4Gb (2400) and newer controllers. FC-Tape is highly recommended for connections to tape drives that support it. It encompasses four elements from the T-10 FCP-4 specification:

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.

Firmware loading is supported if the ispfw(4) module is loaded. It is strongly recommended that you use the firmware available from ispfw(4) as it is the most likely to have been tested with this driver.

Target mode support for Fibre Channel adapters may be enabled with the

options ISP_TARGET_MODE

option.

To disable FC-Tape, use the following configuration option:

options ISP_FCTAPE_OFF

Note that even if the ISP_FCTAPE_OFF option is used, it may be overridden by the fctape hint described below.

The following options are switchable by setting values in /boot/device.hints.

They are:

hint.isp.0.fwload_disable
A hint value to disable loading of firmware ispfw(4).
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:

Prefer loopback and fallback to point to point.
Prefer point to point and fallback to loopback.
Loopback 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 or Loop ID. For Fibre Channel cards in Local Loop topologies it is strongly recommended that you set this value to non-zero.
hint.isp.0.role
A hint to define default role for isp instance (0 -- none, 1 -- target, 2 -- initiator, 3 -- both).
hint.isp.0.debug
A hint value for a driver debug level (see the file /usr/src/sys/dev/isp/ispvar.h for the values.
hint.isp.0.vports
A hint to create specified number of additional virtual ports.
hint.isp.0.nofctape
Set this to 1 to disable FC-Tape operation on the given isp instance.
hint.isp.0.fctape
Set this to 1 to enable FC-Tape operation on the given isp instance for targets that support it.

dev.isp.N.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.
dev.isp.N.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.
dev.isp.N.use_gff_id
 
dev.isp.N.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).
dev.isp.N.wwnn
This is the readonly World Wide Node Name value for this port.
dev.isp.N.wwpn
This is the readonly World Wide Port Name value for this port.

The isp driver was written by Matthew Jacob originally for NetBSD at NASA/Ames Research Center. Later improvement was done by
Alexander Motin <mav@FreeBSD.org>.

The driver currently ignores some NVRAM settings.

Fabric support for 2100 cards has been so problematic, and these cards are so old now that it is just not worth your time to try it.
