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

Installing and Configuring the Linux Host with the Emulex Driver

Table 7 provides a listing of the EMC-recommended settings for the

driver. These values will be used as default when installing the

driver.

* If PEMC owerPath,

Veritas DMP, or Linux native multipath (DM-MPIO) is installed,

lpfc_nodev_tmo must be set to 10.

Descriptions of the Emulex parameters

lpfc_link_speed Specifies link speed selection for the initialization of the FC

connection.

0 = auto negotiate

1 = 1 GB

2 = 2 GB

4 = 4 GB

The auto-negotiation feature may not be suitable in all environments.

In such an environment, EMC recommends explicitly setting the link

speed.
