Overview

This guide describes how to install, upgrade, configure, and remove Sun Raytrademark Server Software 4.1. It also provides instructions for upgrading to the appropriate version of Linux.

The reader is presumed to be familiar with basic Linux commands and to have experience in network configuration and administration. Technical information and procedures are presented with a command-line interface.

The installation flow chart (FIGURE 1-1) and network configuration flow chart (FIGURE 1-2) summarize the tasks to be performed. Following the procedures in this guide can help to avoid unnecessary problems when you install, upgrade, or configure Sun Ray systems.


Media Formats

Sun Ray Server Software 4.1 is available on CD-ROM and ESD (electronic software download). If you download the software electronically, then when instructions and procedures in this guide ask you to change to the image directory on the CD-ROM, please change instead to the image directory under the download directory. Commands issued in either file system should execute properly.


Installation Flow Chart

The following diagram shows the key decisions you should take before performing an installation or upgrade.

This flowchart depicts key decisions that must be taken before installing or upgrading.First, select a target Solaris OS release for Sun Ray Server Software 4.1. If the target OS requires no upgrade, then install the SRSS 4.1 with data preserved automatically, and you’re done.
If the target OS does require an upgrade, determine whether the installed SRSS supports the new target OS. If so, update the Solaris operating environment, then install the Sun Ray Server Software 4.1 as above. If not, then preserve the existing Sun Ray configuration and data, unconfigure and remove installed Sun Ray server software, then update the Solaris operating environment and, finally, install Sun Ray Server Software 4.1 with preserved data.
