Introduction Purpose of this document This document is meant to assist in the installation and configuration of QLogic Fibre Channel host bus adapters (HBAs) and Fibre Channel Over Ethernet (FCoE) converged network adapters (CNAs), and iSCSI HBAs in Linux environments. The focus of this document is to enable the integrated QLogic driver in the Linux distributions ® for EMC -supported QLogic adapters or Fibre Channel adapters or to set up Linux hosts using the EMC-supported driver for QLogi

Introduction ◆ In virtualization environments, where several physical storage and network links are commonly required. The installation of the QLogic FCoE CNA provides the host with an Intel-based 10 gigabit Ethernet interface (using the existing in-box drivers), and an QLogic 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

Introduction Boot device support Linux hosts using QLogic adapters have been qualified for booting from EMC storage array devices interfaced through Fibre Channel and iSCSI as specified in the EMC Support Matrix. ® ™ ® The EMC Symmetrix , EMC VNX series, or EMC CLARiiON device 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 should be mapped as /dev/sda by the Linux operating sys

Introduction Zoning This section contains general configuration guidelines when connecting a Linux server via Fibre Channel or iSCSI to an EMC storage array. Note: Multi-initiator zones are not recommended in a Linux fabric environment. FC and FCoE When using Linux hosts in a fabric environment, the zoning must be set up as single initiator and single target zoning. A single initiator/single target zone is composed of one adapter and one EMC storage array port. Storage array ports can be s
