Boot device support

Introduction
The benefits of FCoE technology become apparent in large data
centers:
◆ Where dense, rack-mounted and blade server chassis exist.
◆ Where physical cable topology simplification is a priority.
◆ In virtualization environments, where several physical storage
and network links are commonly required.
The installation of the Emulex FCoE CNA provides the host with an
Intel-based 10 gigabit Ethernet interface (using the existing in-box
drivers), and an Emulex Fibre Channel adapter interface, which
requires the installation of the supported driver revision.
Following installation of the proper driver for the FCoE CNA, the
Fibre Channel interface will function identically to that of a standard
Emulex Fibre Channel HBA. The FCoE CNA simply encapsulates
Fibre Channel traffic within Ethernet frames. As such, FC-based
content within this document also applies directly to the Emulex
FCoE CNAs.
In-depth information about FCoE and its supported features and
topologies can be found in the EMC Fibre Channel over Ethernet (FCoE)
TechBook available at the Topology Resource tab in the E-Lab
Interoperability Navigator at http://elabnavigator.EMC.com.
Boot device support
Linux hosts using Emulex adapters have been qualified for booting
from EMC storage array devices interfaced through Fibre Channel as
specified in the EMC Support Matrix.
The EMC Symmetrix

, EMC VNX
™
series, and EMC CLARiiON
®
system that is to contain the Master Boot Record (MBR) for the host
must have a lower logical unit number (LUN) than any other device
visible to the host. This device must be mapped as
/dev/sda by the
Linux operating system for the boot to succeed from the device.
Refer to Chapter 7, ”Configuring a Boot Device on an EMC Storage
Array,” for further information on booting from the SAN.troduction
