Setting Up Integrated Mirroring 15

Setting Up Integrated Mirroring

This chapter describes how to set up IM using the BIOS-based configuration utility (CU). The

chapter includes these topics:

• "IM Configuration Overview" on page 15

• "Configuring IM with the BIOS-Based CU" on page 15

• "How to..." on page 24

• "Troubleshooting" on page 25

IM Configuration Overview

The following constraints were made in order to simplify the IM configuration:

• The BIOS-based CU allows you to create one mirrored volume per PERC 4/IM controller.

• Disks in an IM volume must be qualified by Dell to provide support for this platform.

• Disks of different size are allowed in mirrored volumes, but the smallest disk determines the

“logical” size of each disk in the volume. The excess space of larger member disks is not used.

Configuring IM with the BIOS-Based CU

The BIOS-based CU is part of the Fusion-MPT BIOS. When the BIOS loads during boot and you

see the message about the BIOS Configuration Utility, press

Ctrl-M

to start the utility. After you

do this, the message changes to:

“Please wait, invoking LSI Logic Configuration Utility...”

Configuration Screen Overview

All of the BIOS-based CU screens are partitioned into the areas shown in Figure 3-1 on page 16.
