Preparing the Host System 3-7 4. Open the Properties screen by right-clicking and selecting Properties, once Properties is open, select the Driver tab. 5. From the Driver screen, select the Update Driver button to begin the Upgrade Device Driver Wizard. 6. From the second screen of the wizard, select Display a list of the known drivers for this device so that I can choose a specific driver. 7. In the third screen of the wizard, click the Have Disk button, then the Install From Disk Box will appear. Select Browse. 8. From Browse, select CD-ROM. Then, from the CD that came with your kit, open the KGPSA folder. 9. Once the KGPSA folder opens, select the WIN2K folder for OEM set up. Proceed through the remaining steps of the wizard to complete the driver installation. Initial Setup Settings Terms and Definitions The following terms and definitions will be helpful to understand when making initial set up choices. s SCSI−Data transfer protocol used in computers and storage systems. SCSI-3 is a superset of SCSI-2. s CCL−Command Console LUN, a "SCSI Logical Unit Number" virtual-device used for communicating with Command Console Graphical User Interface (GUI) software. s Failover−The ability for HSG80 controllers to transfer control from one controller to another in the event of a controller failure. This ensures uninterrupted operation. Use Transparent Failover mode for single HBA configurations. Use multiple-bus failover mode for Secure Path based configurations. s Fibre Channel−Very high-speed data bus protocol and technology used to connect computer components. It is what connects the system to your server. Use Arbitrated Loop mode for hub configurations and Fabric mode for switches.
