LSI Logic LSI20320-R
Host Bus Adapter
Thank you for purchasing the LSI20320-R Host Bus Adapter (HBA).
Please take a few minutes to read this quick hardware setup guide
before you install the LSI20320-R. If you need more information
about any topic covered in this guide, please refer to the other
documents on the accompanying LSI Logic Host Bus Adapter
compact disk (CD).
Contents of the LSI Logic Host Bus Adapter CD
The LSI Logic Host Bus Adapter CD contains utility programs,
device drivers for various operating systems, and the following
documentation:
• LSI Logic Ultra320 SCSI to PCI-X Storage Adapter User’s Guide
• LSI Logic Device Management User’s Guide
• LSI Logic Host Bus Adapter technical product briefs
• Information on SCSI cables
Step 1: Unpack Storage Adapter
Unpack the LSI20320-R in a static-free environment. Remove the
LSI20320-R from the antistatic bag and inspect it for damage. If it
appears to be damaged, or if the LSI Logic Host Bus Adapter CD
is missing, contact LSI Logic or your 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. Be certain
to disconnect the computer from the power and from any networks
before installing the controller card.
Step 3: Install LSI20320-R Host Bus Adapter
Install the LSI20320-R in a 3.3 V or 5 V PCI slot, as shown in
Figure 2. Press down gently, but firmly,to seat the card properly the
slot. The bottom edge of the controller card must be flush with the
slot. Then attach the LSI20320-R to the computer chassis with the
bracket screw. The LSI Logic Ultra320 SCSI to PCI-X Storage
Adapter User’s Guide provides detailed instructions for installing
and configuring the LSI20320-R.
Step 4: Connect the SCSI Devices to the LSI20320-R
Connect SCSI devices to the internal high-density 68-pin SCSI
connectors and/or the external very high-density 68-pin SCSI
connectors. To achieve maximum data throughput, use only
Ultra320 SCSI devices.TheLSI20320-Rsupports up to 15 Ultra320
SCSI devices and a maximum SCSI bus cable length of 12 m.
Disable SCSI termination on all the devices that are not located 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. Figure 1 and the following table provide the location and
definition of the connectors on the LSI20320-R.

Step 5: 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. The LSI20320-R uses
TID 7, which is the highest priority TID. Verify that no two SCSI
devices use the same TID; change the TIDs as needed. See the
SCSI device documentation for instructions concerning changing
the SCSI device’s TID.

Step 6: Set SCSI Termination
The SCSI bus, which consists of the SCSI bus cables and SCSI
devices, is an electrical transmission line that must be terminated
properly to minimize signal reflections and prevent data loss.
Enable SCSI termination at each end of the SCSI bus (channel)
and only at the ends of the SCSI bus. Figure 3 illustrates the
termination for internal SCSI devices connected on a SCSI bus.
The LSI20320-R automatically terminates its end of the SCSI bus
if only internal devices or only external devices connect to that
channel. The LSI20320-R automatically disables termination if both
internal and external devices connect to that channel, because the
LSI20320-R is then in the “middle” of the SCSI bus.

(Termination Disabled on Both)
For a disk array, set the SCSI bus termination so that removing or
adding a SCSI device does not disturb termination. To do this,
connect the LSI20320-R 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. Figure 4 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 TID 6.

Some disk enclosures handle termination for the SCSI devices
within the enclosure. Refer to the enclosure documentation for
more information.
Step 7: Power Up the Computer
Replace the computer cover and connect the power cords. Turn on
the power to all the devices. Be sure the SCSI devices power up
before or at the same time as the computer. Otherwise, the
computer might not recognize the SCSI devices.
Step 8: Run the BIOS Configuration Utility
During boot, the following message appears:
Press <Ctrl-C> to start the LSI Logic Configuration Utility
When this message appears, press <Ctrl-C> to run the LSI Logic
BIOS Configuration Utility. The Fusion-MPT Device Management
User’s Guide provides instructions for using the LSI Logic BIOS
Configuration Utility.
Step 9: Install the Operating System Driver
LSI Logic provides device drivers for the following operating
systems:
• MS-DOS version 6.xx or later
• Microsoft Windows NT 4.0, Windows 2000, Windows XP, and
Windows Server 2003
• Novell NetWare 5.1 and 6.0
• Red Hat Linux 7.2 and 7.3
Integrated RAID
The LSI20320-R supports integrated RAID, which includes
Integrated Mirroring™ (IM) and Integrated Striping™ (IS). IM
enables mirroring of two to six drives in a disk array. IS enables
data striping across up to six drives.
