1 Overview

The purpose of this document is to provide clear instructions on how to install and use

HPT37x ATA RAID controllerson Red Hat Linux system.

The driver supports following the HighPoint ATA RAID controllers:

HPT370 UDMA/ATA100 RAID Controller

HPT372 UDMA/ATA133 RAID Controller

HPT372A UDMA/ATA133 RAID Controller

2 Installing Red Hat Linux on HPT370/372/372A

Controller

If you would like to install Red Hat Linux onto drives attached to HPT37x controller, please

perform the following operations:

Step 1 PrepareYour Hardware for Installation

After you attach your hard disks toHPT37x controller, you can use HPT37x BIOS Setting

Utility to configure your hard disks as RAID 0, RAID 1, RAID 0/1 or JBOD arrays, or just

use them as single disks.

Before installation, you must remove all the disk drives,which are not physically attached

to HPT37x controller, from your system.

Note

If you have other SCSI adapters installed, you must make sure the HPT37x controller

BIOS will be loaded firstly. If not, try to move it to another PCI slot. Otherwise you may

be unable to boot up your system.

Step 2 Check System BIOS Settings

In your system BIOS SETUP menu, change Boot Sequence in such a way that the system

will first boot from floppy or CDROM, and then from SCSI. Refer to your BIOS manual to

see how to set boot sequence.

If your BIOS settingsdo not support sucha boot sequence, you can first set it to boot from

floppy or CDROM. After you finish installation, set SCSI as the first boot device to boot

up the system.

Step 3 Preparethe Driver Diskette

If you are installing Red Hat Linux 7.0/7.1, just copy all the files under rhdd directory to a

dos formatted diskette.

HPT370/372/372A Red Hat Linux Installation Guide

-2-

If you are installing Red Hat Linux 7.2, the driver is contained in a floppy diskette image

file. If you are using an Athlon CPU, the image file is rh72dd-athlon.img, otherwise, the

image file is rh72dd-i686.img.

On a DOS or Windows system, you can make the Red Hat 7.2 driver diskette using

rawrite.exe. It can be found on the Red Hat Linux CD (under /dosutils). Just run it under a

command window and follow its prompt.

On a Linux system, you can use the “dd” command to make the boot diskette. Insert a

floppy disk into the floppy drive and type the command:

for non-Athlon CPU

# dd if=rh72dd-i686.img of=/dev/fd0

for Athlon CPU

# dd if=rh72dd-athlon.img of=/dev/fd0

Step 4 Preparethe Boot Diskette (Red Hat Linux 7.1/7.2 Only)

If you are installing Red Hat Linux 7.1/7.2 onto hard disk attached to HPT370 or HPT372

controller, you must boot from a customized boot diskette to start installation. There is no

need of customized boot diskette for HPT372A controller.

First obtain the boot diskette image file, rh71boot.imgfor RedHat 7.1 or rh72boot.img for

RedHat 7.2.

On a DOS or Windows system, you can make the boot diskette using rawrite.exe. It can be

found on the Red Hat Linux CD (under /dosutils). Just run it under a command window

and follow its prompt.

On a Linux system, you can use the “dd” command to make the boot diskette. Insert a

floppy disk into the floppy drive and type the command:

RedHat 7.1

# dd if=rh71boot.img of=/dev/fd0

RedHat 7.2

# dd if=rh72boot.img of=/dev/fd0

Step 5 Install Red Hat Linux

1) Start installing Red Hat Linux by booting with the bootable disks or CDROM. If you

are installing Red Hat Linux 7.1/7.2 onto hard disk attached to HPT370/372 controller,

you must boot from the bootable disk provided for HPT37x driver.

2) On "Welcome to Red Hat Linux" installation screen, a prompted label "boot:" will

appear at the bottom of the screen. If you are installing Red Hat Linux 7.0/7.1, type in

HPT370/372/372A Red Hat Linux Installation Guide

-3-

"expert text" (without quotation mark) and then press enter.If you are installing Red

Hat Linux 7.2, type in "expert text updates" (without quotation mark) and then press

enter.

3) If you are installing Red Hat Linux 7.1/7.2, you will be asked “Do you have a driver

disk?”.Select “Yes”.

4) When prompted “Insert your driver disk and press OK to continue”, insert the

driver diskette in the floppy drive and then select "OK".

5) If you are installing Red Hat Linux 7.1/7.2, please go to step 10since the system will

load HPT37x driver automatically.

6) After the "Devices" dialog box appears, select "Add Device"option.

7) When asked "What kind of device would you like to add?",select "SCSI", and then

select "Ok".

8) Scroll down to "HPT370/372/372AATA RAID Controller", and then select "Ok".

9) The installation process will now display the "HPT370/372/372A ATA RAID

Controller" as been found, select "Done".

10) If you are installing Red Hat Linux 7.2,when asked “Insert your updates disk and

press ok to continue”, just press <Enter> to continue.

11) Continue the installation as normal. You can refer to Red Hat Linux installation guide.

Note

The system device mapping order is the same as the order shown inHPT37xBIOS

Setting Utility. If you have no other SCSI adapters installed, the device marked as

“BOOT” or “HDD0”will be /dev/sda, “HDD1” will be /dev/sdb, “HDD2” will be

/dev/sdc, etc. When creating mount points, you must mount /boot on /dev/sda.

12) When asked where to install lilo, you must select Master Boot Record (MBR) to

make your system be able to boot from HPT37x controller.For Redhat 7.2, you may

choose GRUB as system loader.

13) (HPT370/372 only) If you are installing Red Hat Linux 7.1/7.2 onto hard disk(s)

attached to HPT370 or HPT372, when “Installation Complete” dialog appears, an

additional step must be taken to replace the installed kernel with our new kernel,

which has HPT366 IDE support removed. On the driver disk, there is a setup script

"postinstall" which will do this work for you. When the "Installation Complete"

dialog appears, DO NOT press ENTER. Press Alt-F2 to activate the command shell

and type in the following commands:

for Red Hat Linux 7.1

# chroot /mnt/sysimage

# mount /mnt/floppy

# sh /mnt/floppy/postinstall

# umount /mnt/floppy

HPT370/372/372A Red Hat Linux Installation Guide

for Red Hat Linux 7.2

# chroot /mnt/sysimage

# mkdir /mnt/floppy

# mount /dev/fd0 /mnt/floppy

# sh /mnt/floppy/postinstall

# umount /mnt

Then press Alt-F1to return to the setup screen and press ENTER to finish setup.

3 Installing HPT370/372/372A Driver on an

Existing System

If you are currently running Linux and would like to access drives or arrays attached to the

HPT37x controller, you can perform the following steps.

Note

1. If you use a SCSI adapter to boot your system, you must make sure the HPT37x

controller BIOS will be loaded after that adapter’s BIOS. If not, try to move it to

another PCI slot. Otherwise you may be unable to boot up your system.

2. If you are using a multi-processor system, you must boot from a uniprocessor kernel to

install the driver since current driver does not support SMP. For HPT370/372A, you

can just boot from “Linux UP”if it is available. For HPT372, you must first update the

kernel with “vmlinuz.hpt37x2”on the boot diskette.

3. A defect in default Red Hat Linux 7.1/7.2 kernel will hang your system during boot

phase with HPT372 chip. So, if you want to use HPT372 chip with Red Hat Linux

7.1/7.2 system, you should boot from the provided boot floppy and update the kernel

first.

Step 1 Obtain the Driver Module

You can extract the module file from the file modules.cgz on the driver disk. Using the

following commands:

# mount /dev/fd0

# cd /tmp

# gzip -dc /mnt/floppy/modules.cgz | cpio -idumv

Driver modules for different kernel version will be extracted:

/tmp/2.2.16-22/hpt37x2.o Red Hat Linux 7.0 driver

/tmp/2.4.2-2/hpt37x2.o Red Hat Linux 7.1 driver

/tmp/2.4.7-10/hpt37x2.o Red Hat Linux 7.2 driver

Step 2 Updatethe Kernel(Red Hat Linux 7.1/7.2 Only)

If you are about to use Red Hat Linux 7.1/7.2 system with HPT370 or HPT372

HPT370/372/372A Red Hat Linux Installation Guide

controller, you must update the kernel to remove HPT366 IDE support from it first.

There are two ways to do this.

1. Building a new kernel from kernel source

To build a new kernel, you must have installed kernel source and related packages.

These packages are:

kernel-headers

kernel-source

make

binutils

glibc-devel

ncurses

ncurses-devel

cpp

gcc

You can find these packages (.rpm file) under directory RedHat/RPMS/ on Red Hat

Linux CD. You can use command “rpm –i”to install an .rpm file.

After all required packages are installed, follow these steps to build a new kernel:

1) Use the following command to add a link to the source directory:

for RedHat 7.1

# ln –s /usr/src/linux-2.4.2 /usr/src/linux

for RedHat 7.2

# ln –s /usr/src/linux-2.4.7-10 /usr/src/linux

2) Remove the following 2 lines from /usr/src/linux/drivers/ide/ide-pci.c:

{DEVID_HPT34X, "HPT34X", PCI_HPT34X, NULL, ...

{DEVID_HPT366, "HPT366", PCI_HPT366, ATA66_HPT366, ...

3) If you are using RedHat 7.2 on Athlon type CPU, you need to check kernel type

setting every time before rebuilding new kernel. Using the commands below:

# cp /boot/kernel.h /boot/kerne.h.old

# sed 's/i686/athlon/g'/boot/kernel.h.old > /boot/kernel.h

4) Type in the following commands to configure the kernel:

# cd /usr/src/linux

# make clean

# make menuconfig

Now the kernel configuration dialog will appear. You can adjust the options

based on your running system’s hardware/software configuration. For most

options you can simply use the default setting except the following:

HPT370/372/372A Red Hat Linux Installation Guide

-6-

a.Since current driver does not support SMP, you should disable SMP support

by deselecting the option “Processor type and features->Symmetric

multi-processing support”.

b.Enable kernel versioning option by selecting “Loadable module

support->Set version information on all module symbols”.

c.Configure SCSI support and SCSI disk support as module by setting “SCSI

support->SCSI support”and “SCSI support->SCSI disk support”as

module.

d.Enable initial RAM disk support by selecting “Block devices->RAM disk

support”and “Block devices->Initial RAM disk (initrd) support”.

e.Enable loopback device support by selecting “Block devices->Loopback

device support”.

f.For convenience, you can enable the option “File systems->DOS FAT fs

support”to easily access DOS floppies.

When you finish, select “Exit”and save the kernel configuration when

prompted.

5) Type in the following command:

# make dep

Note

1.For RedHat 7.0/7.1, the file /usr/src/linux/include/linux/modversions.h may

be incorrect after “make dep”in some Red Hat Linux distributions. Please

check if there is a line “#include <linux/rhconfig.h>” before “#include

<linux/modsetver.h>” in that file. If not, you should add the line manually.

2.For RedHat 7.2, you have to check kernel version after running “make dep”.

The UTS_RELEASE define line in /usr/src/linux/include/linux/version.h

should be

#define UTS_RELEASE “2.4.7-10”

If not, correct it using an editor (eg. vi)

6) Type in the following command to build the kernel image:

# make bzImage

If the kernel is built successfully, you can copy the new kernel file

/usr/src/linux/arch/i386/boot/bzImage to /boot directory.

# cp /usr/src/linux/arch/i386/boot/bzImage /boot

For more information on how to build and install a new kernel from kernel source,

please refer to Linux kernel documents. The Kernel-HOWTO document gives a

detailed guide to kernel configuration, compilation, upgrades, and troubleshooting.

2. Using the kernel on the driver diskette

HPT370/372/372A Red Hat Linux Installation Guide

-7-

If you do not want to build the kernel by yourself, you can simply use the kernel

"vmlinuz.hpt37x2" on the driver diskette we provided.

After you get the new kernel, you can install it using Grub or Lilo. Follow the steps

below.

Using Grub

For RedHat 7.2, you can choose using Grub to boot system kernel.

1) Copy the new kernel image to the boot directory. Here we name it to

/boot/vmlinuz.hpt37x2. You can change it to whatever name you want.

2) Modify /boot/grub/menu.lst settings to install the new kernel configuration. You

can use the command “vi /boot/grub/menu.lst” to open menu.lst with the vi editor

and modify it. Generally you can add the following lines to the file (in this example,

we name the new kernel file as “vmlinuz.hpt37x2”.):

title RedHat Linux (2.4.7-10.hpt37x2)

root (hd0,0) Grub’s root device

kernel /vmlinuz.hpt37x2 ro root=/dev/hda5 The new kernel image

initrd /initrd-2.4.2-2.img RAM disk file, see below

Note

a) Your grub’s root device may be not on (hd0,0). Check the correct location and

modify the line “root (hd0,0)” to match your system configuration.

b) Your system’s root file system may be not on /dev/hda5. Check the correct

location and modify the line “root=/dev/hda5” to match your system

configuration. You can use the “mount”command to see on which device you

boot file system is mounted.

c) If your system needs an initial RAM disk image to boot up (especially when

you use a SCSI drive to boot), you should check existing sections in your

menu.lst file for the “initrd”line and add it to the new section. The default

RAM disk file name is initrd-2.4.2-2.img for Redhat 7.1, initrd-2.4.7-10.img

for Redhat 7.2.

Using Lilo

1) Copy the new kernel image to the boot directory. Here we name it to

/boot/vmlinuz.hpt37x2. You can change it to whatever name you want.

2) Modify /etc/lilo.conf settings to install the new kernel. You can use the command

“vi /etc/lilo.conf” to open lilo.conf with the vi editor and modify it. Generally you

can add the following lines to the file (in this example, we name the new kernel file

as “vmlinuz.hpt37x2”.):

image=/boot/vmlinuz.hpt37x2 The new kernel image

label=linux.hpt37x2

initrd=/boot/initrd-2.4.2-2.img RAM disk file, see below

read-only

HPT370/372/372A Red Hat Linux Installation Guide

-8-

root=/dev/hda5 Root file system, see below

Note

a) Your root file system may be not on /dev/hda5. Check the correct location and

modify the line “root=/dev/hda5” to match your system configuration. You can

use the “mount”command to see on which device you root file system is

mounted.

b) If your system needs an initial RAM disk image to boot up (especially when

you use a SCSI drive to boot), you should check existing sections in your

lilo.conf file for the “initrd=”line and add it to the new section. The default

RAM disk file name is initrd-2.4.2-2.img for Redhat 7.1, initrd-2.4.7-10.img

for Redhat 7.2.

3) Tell lilo to boot the new kernel by default by modifying the “default=” line to

“default=linux.hpt37x2”.

4) After you finish the modification, save the file and exit the editor,then use the

command “lilo” to install the new kernel.

5) If “lilo”finishes without error, reboot from the new kernel to go to the next step,

“Test the Driver Module”.

Step 3 Test the Driver Module

You can test out the module to ensure that it works for your system by changing

working directory to the location where hpt37x2.o resides and typing in the command

"insmod hpt37x2.o".

Sometimes insmod will report "unresolved symbols" when you attempt to load the

module. This can be caused by two ways:

1)If your system is using a kernel which has not built-in SCSI support, you must load

the SCSI module before load hpt37x2.o. Try to load SCSI modules first.

E.g. # insmod scsi_mod

# insmod sd_mod

# insmod hpt37x2.o

2)If you recompile the kernel with SCSI support and still receive the "unresolved

symbols" error,it may be caused that you have not configured symbol versioning

correctly. To correct it, recompile the kernel with symbol versioning configured. Please

refer to the kernel documents for more information.

To ensure the module has been loaded successfully,you can check the driver status by

typing in the command “cat /proc/scsi/hpt37x2/X”, where Xis the filename you found

under /proc/scsi/hpt37x2/. Youshould see the driver banner and alist of attached drives.

You can now access the drives as a SCSI device (the first device is /dev/sda, then

/dev/sdb, etc.).
