    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.conf5:

    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 utilizes 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, 2322) and 4-Gigabit (2422, 2432) are also supported. Command tagging is supported for all (in fact, FibreChannel requires tagging). Fabric support is enabled by default for other than 2100 cards. 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.  

    FIRMWARE

    Firmware is available if the ispfw(4) module is loaded during bootstrap (q.v.).

    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.

    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 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 (target, initiator, 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.

     

    SYSCTL OPTIONS

    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 seperate (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.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.

    AUTHORS

    The driver was written by Matthew Jacob originally for NetBSD at NASA/Ames Research Center.  

    BUGS

    The driver currently ignores some NVRAM settings.

    Target mode support is not completely reliable 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).
