12 Customizing your installation

This chapter introduces Ignite-UX configuration files, provides examples of how you can use them, and offers debugging tips. Additionally, it describes how to create local customizations for clients using post-installation scripts, and how to exclude software patch files from archives.

Using configuration files

Ignite-UX is driven by configuration files that define how clients are installed and configured. A configuration file can be thought of as a set of instructions. Ignite-UX provides a set of default configuration files when you install the product. These default configuration files are used until you change or customize them for use in your environment. By creating your own custom configurations, you can:

•Save time during installation

•Ensure standard configurations for similar clients

•Create configurations specific to operating system version or hardware architecture

•Automate all manner of tasks that would otherwise require manual intervention

The configuration file is expressed in a human- readable language, which is fully defined in

instl_adm(4). The configuration file language is much like other programming languages in that it supports the use of variables and conditional expressions. You can create configuration files directly or by using the Ignite-UX GUI.

Most of the important elements that make up an installed system are described in the configuration files:

•Identity of the client, presence of network configuration, and kernel modifications (additional drivers or tunable parameter settings)

•Disk and file system layout

•Software to be installed

•User-defined scripts that run at various points in the installation process to further customize the client

Classes of configuration files

The configuration files used by Ignite-UX during the installation process logically group similar information into classes by operating system and functionality. Figure 94 illustrates the classes of configuration files and their locations.

UX System Management Software specifications

HP-UX System Management Software is a robust suite of tools designed to facilitate the administration and management of HP's Unix-based operating system, HP-UX. As organizations increasingly rely on mission-critical applications, the need for a reliable and efficient management solution becomes paramount. HP-UX provides a comprehensive understanding of system performance, resource utilization, and enterprise-wide configuration, all while maintaining high availability and security.

One of the key features of HP-UX System Management Software is its Advanced System Administrator Toolkit. This toolkit includes a wide array of utilities that streamline daily administrative tasks such as monitoring system performance, managing user accounts, and configuring system settings. Tools such as Glance provide real-time monitoring of system resources, enabling administrators to identify bottlenecks and optimize performance.

The software also boasts an advanced security framework, including features such as Role-Based Access Control (RBAC) and Secure Shell (SSH) for secure data transmission. Security patches and updates can be managed through HP’s Service Pack for HP-UX, which provides a streamlined method for maintaining system integrity and compliance with various regulatory standards.

Another notable aspect is the extensive support for virtualization technologies. HP-UX supports HP’s Integrity Virtual Machines (IVMs) and vPars, allowing administrators to create multiple isolated environments on a single physical server. This not only enhances resource utilization but also improves disaster recovery planning by enabling easier backup and restore processes.

For storage management, HP-UX offers tools that enable easy setup and management of Logical Volume Managers (LVM). This allows simplified disk space allocation and management, ensuring that critical applications have the necessary resources without manual intervention.

Furthermore, HP-UX is designed with compatibility in mind, supporting a wide range of third-party applications and frameworks. Integration with management platforms like HP System Insight Manager enhances the ability to monitor and manage systems from a centralized perspective, providing alerts and reports that help in proactive decision-making.

In summary, HP-UX System Management Software delivers a streamlined approach to system administration, focusing on performance, security, and ease of management. Its advanced features, combined with an emphasis on virtualization and storage management, make it a powerful tool for organizations seeking reliability and efficiency in their Unix-based environments. As businesses continue to evolve, tools like HP-UX will remain crucial for ensuring consistent performance and operational excellence.
