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: .Bl -bullet -offset indent .It Precise Delivery of Commands .It Confirmed Completion of FCP I/O Operations .It Retransmission of Unsuccessfully Transmitted IUs .It Task Retry Identification .El .Pp 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. .Sh HARDWARE The .Nm driver supports these Fibre Channel adapters: .Bl -tag -width xxxxxx -offset indent .It Emulex 16/8G FC GEN 5 HBAS .Bd -literal -offset indent LPe15004 FC Host Bus Adapters LPe160XX FC Host Bus Adapters .Ed .It Emulex 32/16G FC GEN 6 HBAS .Bd -literal -offset indent LPe3100X FC Host Bus Adapters LPe3200X FC Host Bus Adapters .Ed .It Emulex 64/32G FC GEN 7 HBAS .Bd -literal -offset indent LPe3500X FC Host Bus Adapters .Ed .El .Sh UPDATING FIRMWARE Adapter firmware updates are persistent. .Pp Firmware can be updated by following these steps: .Bl -enum .It Copy this code to a .Pa Makefile : .Bd -literal -offset indent KMOD=ocsflash FIRMWS=imagename.grp:ocsflash \&.include .Ed .It Replace .Pa imagename with the name of the GRP file. .It Copy the .Pa Makefile and GRP file to a local directory .It Execute .Cm make and copy the generated .Pa ocsflash.ko file to .Pa /lib/modules .It .Cm sysctl dev.ocs_fc..fw_upgrade=ocsflash .It Check kernel messages regarding status of the operation .It Reboot the machine .El .Sh BOOT OPTIONS Options are controlled by setting values in .Pa /boot/device.hints . .Pp They are: .Bl -tag -width indent .It Va hint.ocs_fc.N.initiator Enable initiator functionality.
