Description
Create a RAID array using the MegaRAID IDE BIOS.
Remove all hard disk drives from your system not physically attached to MegaRAID IDE.
In your system BIOS, change the boot sequence in such a way that the first boot device is the floppy and
the second boot device is the SCSI device.
Boot your system using the boot floppy and the RedHat CD disc in your CD-ROM drive.
Note: The boot floppy is the first disk you created using the AMIBOOT.IMG image. Make sure you
are booting from the floppy. Check the light on the floppy drive is on during boot up. Do not interrupt the
boot process until you reach the first part of the installation (the language selection screen). If you cannot
use the mouse do not continue with these instructions but proceed to section Installing the Operating
System in TEXT mode.
At the first screen, which prompts you to select your language preference, do not click “Next” but instead
press the <CTRL><ALT><F2> keys at the same time. This will bring you to a shell prompt bash#.
Note: This is the only way to partition the array. It cannot be done later in the installation.
At the shell prompt bash#, use FDISK to partition the drive. Type the following command to partition the
array:
Bash# fdisk /dev/mr0
This will prompt you with the following screen:
The number of cylinders for this disk is set to 19589.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

The final command that we will use is <w> and that will write the partition table.

Press <CTRL><ALT><F7> to return to the installation window. Proceed to load RedHat. Stop when it
gives you the option to partition your drive manually or automatically. The window will prompt you with
the following options:
•
•
Remove data
Manually Partition
Select to manually partition your drive. Click Next and the Disk Druid window will appear showing all the
partitions in your array. If you created a RAID 1 array spanning across two drives with three partitions, you
will see a total of six partitions even though you only created three (using FDISK). The reason for this is
because a RAID 1 array exists when you mirror the information on one drive to another. Since you have
created a partition in a RAID 1 array, what you actually did is create a partition on each of the drives.

Click Next, then Exit and Reboot. Remove the floppy and the RedHat CD while your system is
rebooting. When your system boots-up, log in as root.
Step 4 Installing the Monitoring Software
The final step is to install the two RedHat Package Manager (RPM) files. Thy are as
follows:
•
•
Hyperconf-1.0-2.i386.rpm
Kernel-2.2.16-3.i386.rpm.
Go to the directory were these files are located and install them using the following
command:
# rpm –I Kernel-2.2.16-3.i386.rpm.
# rpm –I Hyperconf-1.0-2.i386.rpm
Hyperconf
Hyperconf is the monitoring software that is use to keep track of your RAID array. It is
installed when you install hyperconf-1.0.2.rpm using the RedHat Package Manager
(RPM). This software allows you to monitor the status of you RAID array. It will also
allow you to set a number of variables that will determine the behavior of you RAID array.
Installing Hyperconf
Hyperconf is simple to install. Go to the directory where the RPM file
HYPERCONF-1.0.2.RPM is located. At the command prompt type the following:
rpm –I hyperconf-1.0.2.rpm
This will install the software. The following files are installed on your system:

Activity log file size [] KB
Description
The length of time that can elapse between each status check of the RAID array.
Enter a value for the number of compare errors a drive can have before it is marked as
having failed.
Check this box if you want a drive to be marked as having failed when it has reached the
error threshold + 1.
Start to rebuild a drive automatically if a drive fails.
Check the status of the array at start up to see if a drive has failed and a Rebuild is
required.
Check this box if you wish to stop rebuilding if the error threshold has been surpassed.
Make the contents of all drives identical. A consistency check will examine both drives in
RAID 1 to ensure that the information on both drives are identical. If they are not
identical, checking this box will synchronize the information on both drives.
Check this box to delete the activity log file.
Enter a value for the maximum size (in KB) the activity log file can grow.

Installing MegaRAID IDE on an Existing
Installation
Installing MegaRAID IDE on an Existing Installation
If you have RedHat installed on your system and want to add additional storage, these are
the steps that you should follow.
•
•
•
Upgrade the Linux Kernel to provide support for MegaRAID IDE
Install MegaRAID IDE drive(s)
Install the monitoring software
How to Upgrade the Kernel
The standard Redhat installation installs kernel 2.2.14-5. Redhat Linux kernel 2.2.14-5.0
does not come with support for the CMD chip on the MegaRAID IDE Card. The kernel
must be updated to kernel 2.2.16-22-MegaIDE. This kernel is only available on the LSI
Logic web site at http://www.lsilogic.com.
To upgrade the kernel, follow the steps below:
Step 1
Log on to your system as a super user and go to the /usr/src directory. Find a soft link
called "Linux" and remove it by using "rm Linux". Once the soft link is removed, copy the
2.2.16-MegaIDE kernel to this directory. Extract the file using “tar –zxvf
linux-2.2.16-MegaIDE.tgz. Create a softlink to this directory with the command
ln –s linux-2.2.16-MegaIDE linux
Step 2
In the directory /usr/src/linux run the command "make menuconfig". Under block devices
make sure the following options are selected:
<*>CMD640 chipset bugfix/support
<*>CMD640 enhanced support
<*>Generic PCI bus-master DMA support
<*>CMD64X chipset support
Exit menuconfig saving the configuration. Run the following commands:
"make clean"
"make depend"
"make bzImage"
"make modules"
"make modules_install"
"cp /usr/src/linux/arch/i386/boot/bzImage /boot/2.2.16-MegaIDE"
Step 3
The final steps involves editing the file lilo.conf. This file can be found in the directory
/etc. Open the file using the vi editor with the following command "vi /etc/lilo.conf" and
add the following lines to the file:
image =/boot/2.2.16
label =2.2.16
read-only
root=/dev/hda5

How to Upgrade the Kernel, Continued
The line root=/dev/hda5 will not be correct if you are booting from a different partition.
Look for a previous entry in the file for the correct partition.
root=/dev/hda?
Exit and save lilo.conf.
Run the command "lilo –v"
Reboot.
At the boot prompt hit the tab key. This should give you the option to boot to the new
kernel.

Installing MegaRAID IDE Driver
Download the zipped driver file for RedHat 6.1 and 6.2 from the LSI Logic web site
(http://www.lsilogic.com ). It contains the following files:
•
•
Amiraid.o
MAKEDEV
Create a directory called /usr/src/linux/drivers/block/amiraid and copy the above files to it.
Run the following command:
"./MAKEDEV"
To load Hyperconf driver run the command:
"insmod amiraid.o"
To unload the driver run the command:
"rmmod amiraid"
Note:
The driver will not load unless you have created a RAID.
Installing the Monitoring software
The monitoring software is contained in the zipped driver you download in the last
section.
Install the monitoring software using the command:
"rpm –I hyperconf-1.0-x.i386.rpm"
Note:
Substitute x for the version number.
For instructions on how to use the monitoring software see Chapter 3 Running Hyperconf.

Trouble Shooting
Common Problems
Problem
Hyperconf does not show any
information.
I have saved my options in
Hyperconf but it does not do
what I ask of it.
When I load the driver amiraid.o I
get an error that the driver was
not compiled for this kernel.
Possible Solution(s)
Make sure you have created a RAID, Hyperconf cannot report on what
does not exist.
Check to make sure the daemon (spyd) is running. You can do this but
entering the following command pidof spyd . The number of the
process should be return. If no number is returned the spyd is not
running. Spyd can be started by entering the command spyd. Spyd is
only started at boot time for run level 3.
Force the driver to load using the command insmod –f amiraid.o
