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 LSI21320-R uses
TID 7, which is the highest priority TID. Verify that no two SCSI
devices on the same channel 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 each SCSI bus (channel)
and only at the ends of the SCSI bus. In
, internal SCSI
devices connect to one channel. The LSI21320-R automatically
terminates its end of the SCSI bus if only internal devices or only
external devices connect to that channel. The LSI21320-R
automatically disables termination if both internal and external
devices connect to that channel, because the LSI21320-R is then
in the “middle” of the SCSI bus.
Figure 3 SCSI Termination for Internal SCSI Devices
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 LSI21320-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.
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.
Figure 4 SCSI Termination in a SCSI Disk Array
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 LSI21320-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.
