LSI Logic MegaRAID® SCSI
320-2 Controller
Step Action
8
9
Set SCSI termination.
Replace the computer cover and turn the power on.
10 Run the MegaRAID BIOS Configuration Utility.
11 Install the operating system driver.
Step 1: Unpack MegaRAID Controller
Unpack and install the MegaRAID SCSI 320-2 Controller in a static-free
environment. Remove the MegaRAID controller from the anti-static bag and
inspect it for damage. If it appears to be damaged, or if the Driver and
Documentation CD is missing, contact LSI Logic or your MegaRAID OEM
support representative.
Step 2: Prepare Computer
Turn off the computer and remove the power cord from the back of the power
supply. Remove the cover from the chassis. Make sure the computer is
disconnected from the power and from any networks before installing the
controller card.
Step 3: Check MegaRAID Controller Jumpers
Make sure the jumper settings on the MegaRAID controller are correct. The
jumpers are set at the factory, and you probably do not need to change them.
The following table lists the MegaRAID controller jumpers that you should
check:
Thank you for purchasing the MegaRAID SCSI 320-2 Controller. Please take
a few minutes to read this Quick Hardware Setup Guide before you install the
MegaRAID controller. If you need more information about any topic covered in
this guide, please refer to the other documents on your Driver and
Documentation CD.

J2
SCSI activity indicator: this can be connected to the 4-pin header
hard disk LED on the computer enclosure to display
SCSI bus activity.
The Driver and Documentation CD is packaged with the MegaRAID SCSI
320-2 Controller. The CD contains utility programs, device drivers for various
operating systems, and the following documentation:

S
RAID 5 (Disk striping with distributed parity): Data is striped across all
disks in the array. Part of the capacity of each disk is used to store parity
information that is used to reconstruct data if a disk fails. Provides good
data throughput for applications with high read request rates. (3 to 15 disk
drives)

RAID 10 (RAID 1 and RAID 0 in spanned arrays): Uses mirrored pairs of
disks to provide complete data redundancy. Provides high data throughput
rates. (4 to 14 disk drives)
RAID 50 (RAID 5 and RAID 0 in spanned arrays): Uses both parity and
disk striping across multiple disks to provide complete data redundancy.
Provides high data throughput rates. (6 to 15 disk drives)

Step 9: Power Up the Computer
Replace the computer cover and connect the power cords to all the SCSI
devices and to the computer itself. Turn on the power to all devices. Be sure
the SCSI devices are powered up before the computer or at the same time as
the computer. Otherwise, the computer may not recognize the SCSI devices.
Observe the messages that appear during the boot process, until you see the
message:
Press <Ctrl><M> to run MegaRAID SCSI 320-2 BIOS Configuration Utility
Step 10: Run the MegaRAID BIOS Configuration Utility
When the “Press <Ctrl><M>” message appears on the screen, press
<Ctrl><M> immediately to run the MegaRAID BIOS Configuration Utility. See
the MegaRAID Configuration Software Guide on the Driver and Documentation
CD for information about how to run and use this program.
If your MegaRAID controller includes a backup battery pack, you must
configure it in the BIOS Configuration Utility.
Step 11: Install the Operating System Driver
The MegaRAID controller can operate under MS-DOS® or any DOS-
compatible operating system using the standard AT BIOS INT 13h Hard Disk
Drive interface. To operate with other operating systems, you must install
software drivers. The Driver and Documentation CD includes drivers for the
following operating systems:
S
S
MS-DOS version 6.xx or later
Microsoft Windows NT v4.0, Windows 2000, Windows XP, and
Windows .NET
S
S
Novell NetWare 5.1 and 6.0
Red Hat Linux 7.2 and 7.3
Supported RAID Levels
The MegaRAID SCSI 320-2 Controller supports disk arrays using the following
RAID levels:
S
RAID 0 (Data striping): Data is striped across all disks in the array,
enabling very fast data throughput. There is no data redundancy. All data
is lost if any disk fails. (1-15 disk drives)
S
RAID 1 (Disk mirroring): Data is written simultaneously to two disks,
providing complete data redundancy in case one disk fails. The array
capacity is half of total disk space. (2 disk drives)
