EMC Fibre Channel and iSCSI with QLogic Host Bus Adapters in the Windows Environment

Installation and Configuration

With the latest BIOS installed, configure and verify the BIOS settings

to use the EMC storage array as the boot disk. Ensure that only a

single I/O path to the LUN exists when installing the OS. A single

HBA should have access to only a single array port at this point.

QLogic Fibre Channel HBA BIOS/boot LUN settings

This section describes the steps required to configure a QLogic HBA

boot BIOS for allowing an array-attached LUN to be used as a boot

disk for the server.

This section assumes the following steps have been completed:

◆ The QLogic HBA's BIOS and NVRAM settings are updated to the

latest version. Refer to "“Install/upgrade firmware and boot BIOS

from DOS” on page 25" for details.

◆ In direct-attach configurations, an HBA has a physical connection

to the array port.

◆ In fabric-attach configurations, an HBA has a physical connection

to the switch/fabric, and has been zoned to the array, so a single

HBA to be used for boot has one logical I/O path to the array.

Refer to your switch documentation for details.

Before configuring HBA settings to boot from an array-based LUN,

your server's settings should be adjusted to disable booting from an

internal system drive. The procedure for disabling boot from an

internal system drive is largely dependent upon the server platform.

◆ In some instances, internal boot can be disabled via entering the

onboard SCSI/RAID controller's BIOS utility. For example, an

Adaptec based controller can be configured by pressing CTRL-A,

when the Adaptec banner is displayed during Power-On Self Test

(POST).

◆ Some servers will require entering the system BIOS utility to

either disable boot from an internal drive, or to change the

controller boot order, so the boot HBA is enumerated before the

internal disk controller, allowing the array-attached LUN to be

the first disk visible to the server. Refer to your server

documentation for details.

◆ In some server instances, boot from an internal drive cannot be

explicitly disabled. In this case, the internal drive(s) must be

physically disconnected or removed from the server. Refer to

your server documentation for details.
