OCS_FC(4)

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
