OCS_FC(4) Kernel Interfaces Manual OCS_FC(4) NAME ocs_fc -- Emulex Fibre Channel Host Adapter driver SYNOPSIS device ocs_fc In device.hints(5): hint.ocs_fc.N.initiator hint.ocs_fc.N.target hint.ocs_fc.N.topology hint.ocs_fc.N.speed In loader.conf(5): ocs_fc_load="YES" In loader.conf(5) or sysctl.conf(5): dev.ocs_fc.N.port_state dev.ocs_fc.N.wwpn dev.ocs_fc.N.wwnn dev.ocs_fc.N.configured_speed dev.ocs_fc.N.configured_topology dev.ocs_fc.N.current_speed dev.ocs_fc.N.current_topology DESCRIPTION The ocs_fc driver provides access to Fibre Channel SCSI devices. The ocs_fc driver supports initiator and target modes. Support is avail- able 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 de- vices. Without link level error recovery, an initiator cannot, for in- stance, 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 auto- matically enabled when both the controller and target support it. HARDWARE The ocs_fc driver supports the following PCIe Fibre Channel adapters: * LPe3500X FC Host Bus Adapter (Emulex 64/32G FC Gen 7 HBA) * LPe3200X FC Host Bus Adapter (Emulex 32/16G FC Gen 6 HBA) * LPe3100X FC Host Bus Adapter (Emulex 32/16G FC Gen 6 HBA) * LPe160XX FC Host Bus Adapter (Emulex 16/8G FC Gen 5 HBA) * LPe15004 FC Host Bus Adapter (Emulex 16/8G FC Gen 5 HBA) 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 The following boot options are controlled by setting values in /boot/device.hints: hint.ocs_fc.N.initiator Enable initiator functionality. Default 1 (en- abled), 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 val- ues include: 0 Auto-speed negotiation (default), 4000 (4GFC), 8000 (8GFC), 16000 (16GFC). SYSCTL OPTIONS dev.ocs_fc.N.port_state Port state (read/write). Valid values are online and offline. dev.ocs_fc.N.wwpn World Wide Port Name (read/write). dev.ocs_fc.N.wwnn World Wide Node Name (read/write). dev.ocs_fc.N.fwrev Firmware revision (read-only). dev.ocs_fc.N.sn Adapter serial number (read-only). dev.ocs_fc.N.configured_speed Configured Port Speed (read/write). Valid values are: 0 Auto-speed negotiation (default), 4000 (4GFC), 8000 (8GFC), 16000 (16GFC). dev.ocs_fc.N.configured_topology Configured Port Topology (read/write).
