MegaRAID Controller Installation
Caution: Make a backup of your data before you change your system
configuration. Otherwise you may lose data.
Follow these steps to install the MegaRAID SCSI 320-1 Controller. Each step
is explained more fully in the following text:
Step 1: Unpack MegaRAID Controller
Unpack and install the MegaRAID SCSI 320-1 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 jumpers and connectors on the RAID controller.
Step Action
1 Unpack the MegaRAID SCSI 320-1 Controller.
2 Turn off the computer, remove the power cord, and remove the cover.
3 Check the MegaRAID controller jumper settings.
4 Install the MegaRAID controller.
5 Connect the SCSI devices to the MegaRAID controller.
6 Set the target IDs for the SCSI devices.
7 Set SCSI termination.
8 Replace the computer cover and turn the power on.
9 Run the MegaRAID BIOS Configuration Utility.
10 Install the operating system driver.
Item Description Type

Quick Hardware Setup Guide
The following diagram shows the location of the jumpers and connectors on
the MegaRAID SCSI 320-1 Controller.
Step 4: Install the MegaRAID SCSI 320-1 Controller
Install the MegaRAID SCSI 320-1 Controller in a 3.3 V or 5 V PCI slot, as
shown below. Press down gently, but firmly, to make sure that the card is
properly seated in the slot. The bottom edge of the controller card must be
flush with the slot. Attach the MegaRAID controller to the computer chassis
with the bracket screw.
Step 5: Connect SCSI Devices to MegaRAID Controller
Connect SCSI devices to the internal high-density 68-pin SCSI connector (J1)
and/or the external very high-density 68-pin SCSI connector (J7). To achieve
maximum data throughput, use only Ultra320 SCSI devices. The MegaRAID
SCSI 320-1 Controller supports up to 15 Ultra320 devices at a maximum SCSI
bus cable length of 12 m. You can also connect Ultra160 and Ultra2 SCSI
devices. The MegaRAID SCSI 320-1 Hardware Guide lists the maximum
number of devices and maximum cable length for each kind of SCSI device.
Disable SCSI termination on all devices that are not connected at the end of
the SCSI bus. Use only high- quality ribbon SCSI cables for internal devices
and high-quality round SCSI cables for external devices.
Step 6: Set Target IDs for SCSI Devices
Each connected SCSI device must have a unique Target ID (TID), ranging
from 0 to 15 for 16-bit devices. Note that under DOS ASPI, SCSI devices are
limited to SCSI IDs 1 to 6. The MegaRAID SCSI 320-1 Controller is
automatically assigned TID 7, which has the highest priority. Check all SCSI
devices to make sure that no two devices are set to the same TID. Change
the TIDs as needed. See the SCSI device documentation if you are not sure
how to do this.
Step 7: Set SCSI Termination
The SCSI bus, which consists of connected SCSI cables and SCSI devices, is
an electrical transmission line that must be terminated properly to minimize
signal reflections and prevent data loss. Disk enclosures normally handle
termination for the SCSI devices in the enclosure. Refer to your enclosure
documentation for more information.
SCSI termination must be set at each end of the SCSI bus, as shown in the
following figure. In this example, only internal SCSI devices are connected to
the MegaRAID controller. The MegaRAID controller automatically terminates
its end of the SCSI bus if only internal devices or only external devices are
connected to the SCSI bus. It automatically disables termination if both internal
and external devices are connected to the bus, because the MegaRAID
controller is then in the “middle” of the bus.
For a disk array, set SCSI bus termination so that removing or adding a SCSI
device does not disturb termination. To do this, connect the MegaRAID SCSI
320-1 Controller to one end of the SCSI cable and connect a SCSI terminator
module at the other end of the cable. Attach SCSI devices to the connectors
between the two ends, and disable termination on them. The following
example shows an external drive enclosure with seven SCSI drives.
Termination is enabled at the end of the cable nearest the “last” SCSI drive,
which is assigned SCSI ID6.

Quick Hardware Setup Guide
Step 8: 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 320-1 BIOS Configuration Utility
Step 9: Run 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.
Step 10: 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:
·MS-DOS version 6.xx or later
·Microsoft Windows NT v4.0, Windows 2000, Windows XP, and
Windows .NET
·Novell NetWare 5.1 and 6.0
·Red Hat Linux 7.2 and 7.3
Supported RAID Levels
The MegaRAID SCSI 320-1 Controller supports disk arrays using the following
RAID levels:
·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)
·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)
·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)
