SCSI Termination
Terminate the SCSI devices as shown in the examples, ensuring that only the
devices at the ends of the cables are terminated. SmartRAID V controller
termination is set to
Auto by default and can be changed using Storage
Manager on ROM (SMOR).
If you are using Ultra2 SCSI devices, refer to the “Ultra2 SCSI” section. For
an Ultra device, refer to the documentation that came with the device
By using a 68-pin to 50-pin SCSI cable adapter, an 8-bit SCSI device can be
attached to a Wide SCSI cable along with Wide SCSI devices. However, the
device at the end of the cable must be a Wide SCSI device so that all SCSI
signals are terminated.
For internal and external cables where one cable is an 8-bit (Narrow) SCSI
cable, set the controller termination to
High Only .
