SCSI Connection Overview

Via RAIDWatch GUI

Figure

7: The Terminator Option in RAIDWatch Screen

Select from RAIDWatch’s navigation tree, “Configuration,” “Channel,” and click on

a channel (host) you wish to change its termination mode, and click on one of the

check circles besides “Termination.” Click the “Apply” button to complete the

configuration process.

Typically, the server or host adapter (SCSI card inside the server) is the first device

and is already terminated. When installing the subsystems on a SCSI bus with other

devices, be sure to observe the above rules with all devices on the SCSI bus. Consult

the documentation for your server and/or host adapters for additional information on

correct termination procedures.
