ocs_fc — Device driver for Emulex Fibre Channel Host Adapters
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"
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.
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
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
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).
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). 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).
