booted from a source local to the client system. Regardless of how Ignite-UX is started, it has the same network capabilities once it is running.

•Use bootsys to boot a system already running HP-UX

If the client system is already running HP-UX, the Ignite-UX bootsys command may be used to copy the install kernel and install file system to the client system's HP-UX file system. After reboot, the HP-UX boot loader can boot for installation using that copied content. Ignite config content in the install file system may be used to cause Ignite to automatically switch to use the master Ignite server. Because the initial install environment is copied from the Ignite server, you can be confident the Ignite versions of the initial boot content and software on the Ignite server have the same versions. See “Using bootsys on the client console” (page 98).

•Use DVD media to boot a system for network installation

Ignite supports booting for network installation using standard HP installation media or custom boot media. The version of the Ignite on the media must match the version of Ignite running on the master Ignite server. The simplest way to ensure the versions match is to use make_media_install on the Ignite server to create custom boot media. This custom boot media may be constructed to include [WVI]INSTALLFS config content, which automatically switches to using the Ignite server on startup. Standard HP-UX installation media may also be used to boot the system, as long as the Ignite version on the media matches the master server Ignite version. Standard HP-UX media config content cannot be modified to automatically switch to your Ignite server. See “Creating a boot CD/DVD or an installation DVD” (page 185) and “Tape recovery with no tape boot support — two-step media recovery” (page 217).

•Use vMedia USB DVD to boot a system for network installation

Many Integrity systems support Integrated Lights Out (iLO) Virtual Media (vMedia). This feature must be enabled using a license key. Once enabled, a DVD device or an ISO DVD image on a remote system, such as a PC, may be used. In either case, the client system will appear to have a local USB DVD device.

For more information, see Appendix D (page 242) and the HP Integrity iLO 2 MP Operations Guide available at http://www.hp.com/go/hpsc.

•Boot your Integrity system from a USB memory stick device

It is possible to configure your Integrity system and a USB flash drive in order to boot HP-UX directly from a memory stick device. Once the system is booted to the HP-UX Ignite-UX install environment, you can perform a variety of installation or recovery actions. See the Ignite-UX USB Memory Stick Boot white paper, available at http://www.hp.com/go/ignite-ux-docs, for more information.

Complex networks

Setting up an Ignite server on a simple network assumes there is a single subnet with only one Ignite server that supports network boot and installation. Often, real network environments are significantly more complex. Configuring an Ignite server to operate correctly while avoiding interference with other boot and installation servers on the network requires special consideration.

For a detailed discussion, see Chapter 5 (page 48).

Diagnosing network boot issues

When configuring a network, sometimes boot and installation will not work at all or will not work as expected. Especially when configuring a complex network, you can expect to spend time diagnosing and resolving issues due to the complexity of the network and interactions between servers. You may also expect problems to occur in the future as the complex network changes.

This section includes suggested tools and techniques for diagnosing problems.

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.
