A binary option that sets regular expression matching on the class-idrather than a default literal match. This is a new option for HP-UX 11i v2.
A binary option that sets removal of the class-idfrom message responses. Since bootpd does not support the full Intel Preboot Execution Environment (PXE) protocol, it must not send back a class-idin the response. This is a new option for HP-UX 11i v2.
Different kinds of systems may make PXE boot requests. For example, Itanium-based systems and industry standard servers such as HP ProLiant servers may each make a PXE boot request. It is unlikely the same configuration can be used for these different requests. The class-idmay be used to respond to PXE requests from the correct clients, while ignoring the wrong ones.
All Itanium-based servers send a 32 character PXE boot request in the following format:
PXEClient:Arch:00002:UNDI:xxxyyy
where xxxyyy are major and minor numbers for the Universal Network Device Interface revision.
An industry standard server, such as an HP ProLiant server, sends a PXE boot request in this format:
PXEClient:Arch:00000:UNDI:xxxyyy where xxxyyy are the same as described above.
The class-idin the dhcp_device_group example above tells the bootpd daemon to respond only to clients with a boot request containing PXEClient:Arch:00002. Requests from industry standard servers are ignored.
Configuring an Ignite server to boot anonymous Itanium-based clients 45
Starts a DHCP device pool group for allocating a range of IP addresses to assign to clients with a matching class-idin their boot requests.

Make sure that at a minimum, HP-UX 11i v2 is installed on your Ignite-UX server or boot helper system.

Add your device pool group entry to the /etc/dhcptab file on your Ignite-UX server or boot helper system.

You do not need to restart bootpd if it is already running. When a new bootp DHCP request is received, bootp checks to see whether it must reread any configuration files. If you want to force bootp to reread the configuration file, send it the SIGHUP signal.

The following example DHCP device group is the best way to support anonymous Itanium-based clients:

dhcp_device_group:\ re:\

ncid:\ class-id="PXEClient:Arch:00002":\ lease-time=300:\ subnet-mask=255.255.255.0:\ addr-pool-start-address=192.168.1.10:\ addr-pool-last-address=192.168.1.20:\ bf=/opt/ignite/boot/nbp.efi

The options in the dhcp_device_group clause are: dhcp_device_group

re

ncid

class-id

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.
