About this guide

This guide provides information about:

• Preparing your environment prior to installing software

• Installing the software

• Verifying successful installation and troubleshooting problems

Intended audience

This guide is intended for use by system administrators who are experienced with the following (depending on the type of installation):

• SUSE LINUX Enterprise Server 8 (SLES) or Red Hat Enterprise Linux 3 (RHEL) operating systems

(abbreviated to Linux throughout this guide)

NOTE: You must have a thorough knowledge of Linux and be logged on to the system as root in

order to execute shell commands.

• Windows Server 2003 or Windows 2000 Server operating systems (abbreviated to Windows

throughout this guide)

NOTE: You need administrative privileges to perform the administrative tasks. These privileges are

granted only if you are either locally logged to the system as Administrator (recommended) or using a remote access software that supports logging in with the real Administrator account. The Windows native Remote Desktop tool, for example, may be unsuitable for these tasks, since it uses a different Administrator account when logging in remotely.

Once the software is successfully installed, you then need to configure File System Extender (FSE) resources, such as disk media and tape libraries, HSM file systems, and configure migration policies. This configuration is described in the FSE User’s Guide.
