HP dx5150 RAID Installation

and Setup Guide

Introduction

RAID (Redundant Array of Independent Disks) technology

manages multiple disk drives to enhance I/O performance and to

provide redundancy in order to withstand the failure of any

individual member without loss of data.

SATARAID™ provides two RAID Set types: Striped Set (RAID

0) and Mirrored Set (RAID 1).

Disk Mirroring (RAID 1)

Disk mirroring creates an identical twin for a selected disk by

writing the data simultaneously to two disks. This redundancy

provides protection from a single disk failure. If a read failure

occurs on one drive, the system then reads the data from the other

drive.

Disk Striping (RAID 0)

Striping is a performance-oriented, non-redundant data mapping

technique. It does not provide fault tolerance. With modern

SATA and ATA bus mastering technology, multiple I/O

operations can be performed in parallel, enhancing performance.

Striping arrays use multiple disks to form a larger virtual disk.

Steps to Set Up RAID 1 in Mirror Mode

Enable RAID in the Computer BIOS:

1. Select ‘Integrated Peripherals’ in the Main Menu of F10

BIOS setup.

2. Select the ‘South OnChip PCI Device.’

3. Select ‘Onboard Chip SATA.’

4 www.hp.com Installation and Setup Guide

HP dx5150 RAID Installation and Setup Guide

4. When the ‘Onboard Chip SATA’ appears, select ‘RAID

Controller,’ press Enter to accept this selection and save the

setting to CMOS.

Note: To increase the amount of time needed to access the BIOS

RAID utility during post, you can change the default value of

zero seconds. The option to change the ’POST Delay’ is in the

F10 BIOS Setup in the ’Standard CMOS Features’ menu.

Create RAID Sets

1. During computer startup (POST), press the F4 function key to

display the BIOS RAID Configuration Utility.

2. Select ‘Create RAID set’ option.

3. Choose RAID 1 Mirrored Set

Installation and Setup Guide www.hp.com 5

4. Select ‘Automatically Configure’ option.

5. Assign the source and target drive.

6. The message ‘Are You Sure?’ will display before completing

the configuration. Answer ‘N’ to abort the creation of the

new RAID set, or ‘Y’ to proceed with the RAID set creation.

7. Install the drivers for RAID in the Windows operating

system. Step 1a or 1b will need to be performed depending

on OS installation status.

Install RAID Drivers

Note: To install RAID Drivers while installing Microsoft

Windows XP operating system on the computer, go to

”B. Installing RAID Drivers during Microsoft Windows XP OS

Installation”.

A. Installing RAID Drivers on Microsoft Windows XP OS

1. Run the SETUP program for the ATI South Bridge Drivers

which are located in C:\Compaq\RAID\Setup on your HP

dx5150 computer or may be downloaded from the HP Web

site (www.hp.com or

http://h20180.www2.hp.com/apps/Lookup?h_lang=en&h_c

c=us&cc=us&h_page=hpcom&lang=en&h_client=S-A-R163-1

&h_pagetype=s-002&h_query=dx5150&submit.x=4&submit.y

=9). Please check the HP support Web site for possible

updates to these drivers in the future. Follow the instructions

on the screen once the SETUP program is launched.

2. Verify the drivers are installed after restarting the operating

system (the setup program in the previous step will prompt

for a system restart).

a. Right click on ‘my Computer’ icon, select ‘Properties,’

left click on ‘Hardware’ tab, and then on ‘Device

Manager’ button.

HP dx5150 RAID Installation and Setup Guide

b. Double click on ‘SCSI and RAID Controllers.’ If there is

no yellow '!' or '?' in front of ‘ATI Serial ATA

Controller,’ the driver is installed correctly.

B. Installing RAID Drivers during Microsoft Windows XP

OS Installation

1. The RAID drivers are in the C:\Compaq\RAID\INF folder on

your HP dx5150 computer or may be downloaded from the

HP Web site (www.hp.com). Please check the HP support

Web site for possible updates to these drivers in the future.

The RAID drivers are included in the ATI Chipset softpaq.
