    This chapter provides detailed information on how to configure the server using the System Configuration Utility (SCU). Digital recommends that you use the SCU to initially configure the server and each time you add hardware, remove hardware, or change server settings.

  • Page 15: The Scu

    Digital PRIORIS XL Server Digital PRIORIS XL Server Utilities & Configuration Utilities & Configuration The SCU The SCU enables you to setup and configure the server using the menu driven items shown in figure 2-1. Depending on the installed hardware and level of server security required, you might have to access one or more of these items to properly configure the server.

  • Page 16: Before Using The Scu

    The SCU creates a System Configuration Information (SCI) file each time you configure the server. This SCI file can be used on other PRIORIS XL Servers that are equally configured and can serve as a backup to the EISA configuration stored in NVRAM memory. The SCI file is maintained on the System Configuration Utility diskette and has a default name SYSTEM.SCI.
