netmask[] = "255.255.255.0" route_gateway[0] = "10.3.1.1" route_destination[0] = "default" disable_dhcp = "true"

If DHCP is used, this will not be required since the DHCP server must provide appropriate routing information.

IMPORTANT: The sd_server IP address setting in the installation file system will be overridden by sd_server settings in configuration files created by make_config. To use IINSTALLFS to control the sd_server setting you must comment-out or remove the sd_server settings within each sw_source clause in the affected configuration files.

For more information about changing IINSTALLFS content, see instl_adm(1M) and instl_adm(4).

Multiple NICs attach the Ignite server to multiple subnets

It is possible to connect one Ignite server to multiple subnets using multiple network interface cards (NICs). The Ignite server can then be used to support network boot and installation on each of these separate subnets. The following diagram is an example of a multiple subnet complex network.

There are some special Ignite configuration considerations for supporting multiple subnets from one server. You must be careful to configure the server so it sends the client correct networking information for its subnet, and you must configure the client so it contacts the correct Ignite-UX server.

Getting the client the correct networking information

The HP-UX Ignite server needs to be configured so the client receives a response from the server with the correct network configuration for its subnet.

The bootptab content for each MAC address needs to have correct networking configuration for the system's subnet. In particular, IP addresses, netmasks, and gateways need to be valid from the client system's perspective. Thus, bootptab will need to include information for all the different subnets used by clients supported by the master Ignite server.

If anonymous network boot is used, care is needed to ensure boot responses are correct. See Chapter 4 (page 43) for more information.

Having the client contact the correct server

The server keyword in the IINSTALLFS configuration information specifies the IP address for your Ignite-UX server. It refers to a specific LAN interface on the Ignite-UX server. The same is true for the sd_server keyword that specifies the depot server IP address for any depots needed for installation.

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.
