EMC Fibre Channel with QLogic HBAs in the Linux x86 Environment

Configuring a Boot Device on the EMC Storage Aray

Installing Red Hat Enterprise Linux 2.1 onto the Boot Device with

the QLogic v6.x Series Driver

The Red Hat Enterprise Linux (RHEL) 2.1 Advanced Server

(v2.4.9-e.3) and Enterprise Server (v2.4.9-e.12) distributions ship with

version v5.31 of the QLogic driver. This version of the driver does not

support fabric boot; therefore, you must use the driver disk

installation method to use a LUN on the storage array as the boot

device.

This section describes the steps that must be taken to successfully

perform the installation environment for both Symmetrix and

CLARiiON arrays. Please be sure to perform the preparatory steps

earlier in this chapter. Also, refer to Limitations on page 3-3 to

familiarize yourself with the restrictions inherent to booting from the

array in a Linux environment.

The installation process consists of the following distinct

components:

1. Building the driver disk — The driver disk must be built for the

correct hardware and software combination.

2. Installing Red Hat Enterprise Linux 2.1— The installation makes

use of the driver disk to discover the devices that have been set

up previously.

3. Upgrading to the appropriate errata — The final step is to update

the host to the required errata level.

After these steps are completed, the host system is ready for use.

Building a Driver

Disk

The driver disk provides the correct driver and identifying

information needed for the Red Hat Installer to access the devices

presented over the fabric. The driver disk installation method allows

for devices to be discovered at installation time, for which the device

drivers are not part of the standard distribution. Also, this method

can be used to provide an updated version of a driver that is part of

the standard distribution, such as is the case here.

The process of building a driver disk for Red Hat Linux is described

in detail on several websites. In this section, the key steps and specific

requirements for building the particular QLogic HBA driver disks
