EMC Host Connectivity with Emulex FC HBAs and FCoE CNAs for the Linux Environment

Installing and Configuring the Linux Host with the Emulex Driver

What next?

Certain customization features are available in the form of driver

parameter options. These options are read every time the driver is

loaded and included in the newly created RAM disk that includes the

Emulex v8.x driver.

◆ For editing the driver parameters on hosts with SLES 9 SP1 and

newer service packs, and SLES 10 and newer service packs,

proceed to “Editing the Emulex driver parameters on hosts with

SLES 9, SLES 10, and SLES 11” on page 90.

◆ For editing the driver on hosts with RHEL 4 and newer updates,

and RHEL 5, proceed to “Editing the Emulex driver parameters

on hosts with RHEL 4 and RHEL 5” on page 91.

Editing the Emulex driver parameters on hosts with SLES 9, SLES 10, and SLES 11

On hosts with SLES 9 SP1 and newer service packs, SLES 10 and

newer service packs, or SLES 11 and newer service packs, the values

for the driver parameters are set in the file

/etc/modprobe.conf.local..

Refer to “Description of the Emulex lpfc driver parameters” on

page 87 for the description of the supported parameters and to

identify parameters suited to your host.

The following is an example of a modified

/etc/modprobe.conf.local file for a host that is connecting to a

fabric in Point-to-Point at a 2 GB link speed and the log level set as

verbose in order to capture all link events.

cat /etc/modprobe.conf.local

# please add local extensions to this file

## LPFC Module options ##

options lpfc lpfc_link_speed=2 lpfc_topology=0x02

lpfc_log_verbose=0x10

EMC recommends creating a new RAM disk after modifying the

parameters in

/etc/modprobe.conf.local and rebooting the host in

order to use the new RAM disk.
