Introduction
Purpose of this document
Host connectivity
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 QLogic
adapters, available from the EMC-approved section of the QLogic
website.
Review the EMC Support Matrix or contact your EMC representative
for the latest information on qualified adapters, drivers, and Linux
distributions.
Note: EMC does not support mixing different types of Fibre Channel adapter
(including different types from the same vendor) in a server.
Fibre Channel
Fibre Channel over Ethernet
16
EMC Host Connectivity with QLogic FC and iSCSI HBAs and FCoE CNAs for the Linux Environment
The Fibre Channel adapter driver functions as a device driver layer
below the standard Linux SCSI adapter driver. The Fibre Channel
interface therefore is transparent to the Linux disk administration
system.
EMC supports the QLogic Fibre Channel over Ethernet (FCoE)
Converged Network Adapter (CNA). FCoE adapters provide a
method to converge both Fibre Channel and Ethernet traffic over a
single physical link to a switch infrastructure which manages both
storage (SAN) and network (IP) connectivity within a single unit.
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.
iSCSI
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 that of a standard
QLogic Fibre Channel HBA, as the FCoE simply encapsulates Fibre
Channel traffic within ethernet frames. As such, FC-based content
within this document also applies directly to the QLogic FCoE CNAs.
In-depth information about FCoE and its supported features and
topologies can be found in the Fibre Channel over Ethernet (FCoE)
TechBook available through the E-Lab Interoperability Navigator,
Topology Resource Center tab, at http://elabnavigator.EMC.com.
The iSCSI HBA provides PCI connectivity to SCSI using the iSCSI
protocol. iSCSI enables the use of IP-based SANs, which are similar to
Fibre Channel SANs. The QLA40xx-Series HBA implements the
TCP/IP and iSCSI protocols on the HBA and offloads the host of any
I/O protocol processing. This type of adapter is also referred to by
QLogic as an iSCSI Offload Engine (iSOE). Offloading the host frees
the system to perform other tasks and optimizes system performance.
The QLogic iSCSI HBA driver functions as a device driver layer
below the standard Linux SCSI adapter driver. The iSCSI interface,
therefore, is transparent to the Linux disk administration system.
Host connectivity
17
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 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

EMC Host Connectivity with QLogic FC and iSCSI HBAs and FCoE CNAs for the Linux Environment
Zoning
FC and FCoE
Introduction
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.
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 shared among adapters;
however, each adapter must be in its own zone.
Note: Multi-initiator zones are not recommended in a Linux fabric
environment.
iSCSI
Follow the guidelines outlined by EMC. Be aware that using
improper settings may cause erratic behavior. In particular, note the
following:
◆ Each QLogic iSCSI HBA in a Linux server must be on a separate
subnet.
◆ A single host can not mix HBAs and NICs to connect to the same
array or different arrays.
◆ A single host may not attach to an EMC Fibre Channel Array and
an EMC iSCSI Array simultaneously.
◆ QLogic SANsurfer or iscli are required to be installed in order to
configure iSCSI HBAs to connect to iSCSI targets

Prerequisites for first-time installation
In order to complete a first-time installation of the QLogic adpater in
your server, you will need the following:
◆ “Operating system” on page 22
◆ “QLogic SANSurfer and SANSurfer CLI” on page 22
◆ “BIOS and firmware” on page 22
◆ “Linux driver” on page 23
Operating system Before the adapter is installed, the Linux operating system must be
installed and properly configured. Install the Linux kernel from the
distribution installation CD by following the procedure provided in
the distribution installation guide. Partition the boot drive, and select
the packages and services necessary for the host.
Include the kernel source/development package and the gcc
compiler tools during the installation. If these tools are not
installed, then the out-of-kernel driver installation may fail and the
driver will not be installed.
QLogic SANSurfer and
SANSurfer CLI
QLogic's SANsurfer program is a GUI-based utility and the
SANsurfer CLI is a text-based utility. Both applications may be
installed on any Linux system and used to manage, configure, and
update the EMC-approved QLogic adapters.

5. After connecting all adapters in the server, power up the server.
Matching the adapter with the correct PCI slot
When choosing an adapter for your server, it is important to know
which adapter is compatible with your server's PCI/PCI-X/PCI
Express slots. Certain adapter models have specific voltage
requirements or physical limitations that allow them to work only in

specific slots.
Installation Steps
Servers have several different bus slot types for accepting adapters:
◆ PCI
◆ PCI-X
◆ PCI-X 2.0
◆ PCI-Express
PCI slots can be 32-bit and 64-bit (denoted by their 124-pin or 188-pin
connectors.) These slots have plastic "keys" that prevent certain
adapters from fitting into them. These keys work with the cutout
notches in the adapter edge connector so that only compatible
adapters will fit into them. This is done because of the voltage
characteristics of the adapter. Inserting a 3.3v adapter into a 5v slot
would cause severe damage to both the adapter and the server.
Therefore, the slot keys denote the type of voltage provided by the
slot and effectively prevent a voltage incompatible adapter from
being inserted.
Figure 2 shows how PCI slots will appear with their keys and what
type of voltage is provided for each slot type.

Installation Steps
Figure 3 shows the adapter edge connectors compatible with the PCI
slots shown in Figure 2 on page 29. Note adapter 5, which shows a
universal adapter edge connector. Universal adapters are compatible
with both 3.3 V and 5 V PCI slots.

PCI-X (or PCI Extended) slots increase the speed with which data
travels over the bus. PCI-X slots appear identical to a 64-bit PCI slot
keyed for 3.3 V. (Refer to number 3 in Figure 2 on page 29 and
Figure 3.) PCI-X slots are backwards compatible with 3.3 V PCI
adapters and universal adapters. Inserting standard PCI adapters
into PCI-X slots will lower the bus speed as they cannot take
advantage of the improved performance.
PCI-X 2.0 is the next generation of PCI-X buses. PCI-X 2.0 increases
the bus speed again, providing more performance for adapters.
PCI-X 2.0 slots also appear identical to a 64-bit PCI slot keyed for 3.3
V. (Refer to number 3 in Figure 2 and Figure 3.) PCI-X 2.0 is also fully
backward compatible with 3.3 V PCI and PCI-X.
PCI Express (sometimes noted as PCIe) is a new bus type that uses
the existing PCI model, but implements it in a faster, serial protocol.
Because of the serial way it transmits data, the PCI Express bus slot
can be different sizes depending on the throughput it supports. PCI
Express slot speeds are expressed in "lanes" and are normally shown
as x1, x4, x8, and x16. Each type of slot is a different length (as shown
in Figure 4 on page 31) and adapter edge connectors will also be of
varying lengths depending on how many lanes they require for
