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.

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.

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 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.

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.

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.
