Problem installing clients on multiple subnets

Problems occur when installing clients on multiple subnets.

Executing a LAN boot of clients on multiple subnets to a single, multi-homed Ignite-UX server has the following limitations:

•The instl_bootd daemon allocates IP addresses from the instl_boottab file and matches the IP addresses with the subnet from which the request came. If the instl_boottab file does not contain an IP address that is valid for the client's subnet, the client will not be able to boot from the server. Due to this lack of information, it can allocate an IP address that is not valid for the client’s subnet, and thus the client will not be able to boot from the server.

The workarounds for this problem are:

◦For every subnet from which you may want to boot clients, you must have at least one IP address that is valid for that subnet in /etc/opt/ignite/instl_boottab. This ensures that instl_bootd can allocate an appropriate address.

◦For every possible client that you may want to boot, assign "reserved" IP addresses in /etc/opt/ignite/instl_boottab that are tied to the client's MAC address. This ensures that instl_bootd allocates an appropriate address (see the comments in the instl_boottab file on how to reserve addresses).

◦Alternatively, you can set up entries in /etc/bootptab for every client that you want to boot from the Ignite-UX server.

◦Configure a boot helper system on each subnet that the client can boot from before contacting your central Ignite-UX server. See “Ignite-UXbootp boot helper” (page 56).

•The server keyword that specifies the IP address for your Ignite-UX server can only correspond to one of the LAN interfaces. If each subnet is routed such that all clients can use the one IP address to contact their server, then the installation will work. However, it is more efficient for the client to use the server’s IP address that is connected directly to the client’s own subnet. If a client is on a subnet that does not have a route to the IP address specified by server, it will not be able to contact the server after it boots.

Workarounds for this problem are:

◦

◦

Manually correct the server’s IP address on the networking dialog box that appears on the client console when you boot the client.

Use a boot helper on each subnet. When using a boot helper, the server’s IP address can be specified correctly on each helper system.

Too much file space needed

Ignite-UX requests more file system space than expected.

Ignite-UX adds the value of _hp_addnl_fs_free_pct(normally 10 percent) to the amount required by the software impact. The configuration variable, _hp_addnl_fs_free_pct can be set in any configuration file. It is set to a default value of 10 percent in each default release configuration file. You can set this value using the Additional... button on the Basic tab in the Ignite-UX GUI during an interactive installation. For more information, see “Basic tab” (page 118).

You may have software bundles that have overlapping contents (filesets or files or both). The make_config command makes sw_impact statements for each bundle without doing anything special to guard against over-counting when the bundles overlap. For example the Ignite-UX-11-xxbundles all overlap quite a bit so when you install all of them using Ignite-UX, it estimates too much space. To find the space needed, add the sw_impact of all the sw_sel software you are installing.

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.
