33.Sh NAME
34.Nm ocs_fc
35.Nd "Device driver for Emulex Fibre Channel Host Adapters"
36.Sh SYNOPSIS
37To compile this driver into the kernel, add this line to the
38kernel configuration file:
39.Bd -ragged -offset indent
40.Cd "device ocs_fc"
41.Ed
42.Pp
43To load the driver as a module at boot, add this line to
44.Xr loader.conf 5 :
45.Bd -literal -offset indent
46ocs_fc_load="YES"
47.Ed
48.Sh DESCRIPTION
49The
50.Nm
51driver provides access to Fibre Channel SCSI devices.
52.Pp
53The
54.Nm
55driver supports initiator and target modes.
56Support is available for Arbitrated loops, Point-to-Point,
57and Fabric connections.
58FC-Tape is highly recommended for connections to tape drives that support
59it.
60FC-Tape includes four elements from the T-10 FCP-4 specification:
61.Bl -bullet -offset indent
62.It
63Precise Delivery of Commands
64.It
65Confirmed Completion of FCP I/O Operations
66.It
67Retransmission of Unsuccessfully Transmitted IUs
68.It
69Task Retry Identification
70.El
71.Pp
72Together these features allow for link level error recovery with tape
73devices.
74Without link level error recovery, an initiator cannot, for instance, tell whether a tape write
75command that has timed out resulted in all, part, or none of the data going to
76the tape drive.
77FC-Tape is automatically enabled when both the controller and target support it.
78.Sh HARDWARE
79The
80.Nm
81driver supports these Fibre Channel adapters:
82.Bl -tag -width xxxxxx -offset indent
83.It Emulex 16/8G FC GEN 5 HBAS
84.Bd -literal -offset indent
85LPe15004 FC Host Bus Adapters
86LPe160XX FC Host Bus Adapters
87.Ed
88.It Emulex 32/16G FC GEN 6 HBAS
89.Bd -literal -offset indent
90LPe3100X FC Host Bus Adapters
91LPe3200X FC Host Bus Adapters
92.Ed
93.It Emulex 64/32G FC GEN 7 HBAS
