NAME

     ocs_fc — Device driver for Emulex Fibre Channel Host Adapters

SYNOPSIS

     To compile this driver into the kernel, add this line to the kernel configuration file:

           device ocs_fc

     To load the driver as a module at boot, add this line to loader.conf(5):

           ocs_fc_load="YES"

DESCRIPTION

     The ocs_fc driver provides access to Fibre Channel SCSI devices.

     The ocs_fc driver supports initiator and target modes.  Support is available for Arbitrated
     loops, Point-to-Point, and Fabric connections.  FC-Tape is highly recommended for
     connections to tape drives that support it.  FC-Tape includes four elements from the T-10
     FCP-4 specification:

           •   Precise Delivery of Commands

           •   Confirmed Completion of FCP I/O Operations

           •   Retransmission of Unsuccessfully Transmitted IUs

           •   Task Retry Identification

     Together these features allow for link level error recovery with tape devices.  Without link
     level error recovery, 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 both the controller and target support it.

HARDWARE

     The ocs_fc driver supports these Fibre Channel adapters:

           Emulex 16/8G FC GEN 5 HBAS

                         LPe15004 FC Host Bus Adapters
                         LPe160XX FC Host Bus Adapters

           Emulex 32/16G FC GEN 6 HBAS

                         LPe3100X FC Host Bus Adapters
                         LPe3200X FC Host Bus Adapters

UPDATING FIRMWARE

     Adapter firmware updates are persistent.

     Firmware can be updated by following these steps:

     1.   Copy this code to a Makefile:

                KMOD=ocsflash
                FIRMWS=imagename.grp:ocsflash
                .include <bsd.kmod.mk>

     2.   Replace imagename with the name of the GRP file.

     3.   Copy the Makefile and GRP file to a local directory

     4.   Execute make and copy the generated ocsflash.ko file to /lib/modules

     5.   sysctl dev.ocs_fc.<N>.fw_upgrade=ocsflash

     6.   Check kernel messages regarding status of the operation

     7.   Reboot the machine

BOOT OPTIONS

     Options are controlled by setting values in /boot/device.hints.

     They are:

     hint.ocs_fc.N.initiator
             Enable initiator functionality.  Default 1 (enabled), 0 to disable.

     hint.ocs_fc.N.target
             Enable target functionality.  Default 1 (enabled), 0 to disable.

     hint.ocs_fc.N.topology
             Topology: 0 for Auto, 1 for NPort only, 2 for Loop only.

     hint.ocs_fc.N.speed
             Link speed in megabits per second.  Possible values include: 0 Auto-speed
             negotiation (default), 4000 (4GFC), 8000 (8GFC), 16000 (16GFC).

             Configured Port Topology (read/write).  Valid values are: 0-Auto; 1-NPort; 2-Loop.

     dev.ocs_fc.N.current_speed
             Current Port Speed (read-only).

     dev.ocs_fc.N.current_topology
             Current Port Topology (read-only).
