Practical considerations

However, if you can remember part of the WWID, you can use the Ignite user interface Disk Selection dialog box Filter text box to limit displayed devices to those with WWIDs containing the text you can remember.

Agile addressing means the hardware path actually used by the system to access a device is independent of the path used to select the device. Selecting a disk via one hardware path might result in the system choosing some other, better hardware path. For example, this can happen when selecting a disk for boot, and when volume managers determine the appropriate set of paths to use for device access.

NOTE: For HP-UX 11i v3, the one hardware path used for selection has no special significance in most Ignite-UX user interfaces. Ignite-UX will allow HP-UX system software to select the best path when a particular path is needed. For example, boot paths will be selected by system software when the boot device is selected.

A more user-friendly approach is to identify I/O devices with a device identifier. A device identifier is a human-readable device ID defined by the user. It can be written to the device and read back. Data centers may want to create some standard policy for device IDs (e.g. LAB2CAB23LUN15).

In the current implementation, the device ID can be set, checked, and read at installation. The device identifier is stored on the device, so it remains available if the disk is moved to a different system or connected to multiple systems. Not all devices support the use of a device identifier.

See the scsimgr(1M) command for more information on how to set and read a device identifier.

When identifying I/O hardware for Ignite-UX configuration files, see Table 5 (page 81) for the format of I/O variables.

NOTE: Your data center may use separate processes or groups to administer systems and storage. It is important to record WWID, Device ID, and other details of LUNs assigned to your systems. Access control or protection zones may be used to control the systems permitted to use a LUN; it is important to record which systems have access to LUNs.

For more details on agile view HP-UX, see the white paper Overview: The Next Generation Mass Storage Stack available at http://www.hp.com/go/hpux-core-docs.

Ignite-UX uses hardware paths to help you identify I/O devices such as disks, CD/DVD drives and tape drives during installation and recovery. The format of the hardware path used to identify I/O devices will depend on the version of HP-UX you are using and other factors. Also, depending on your configuration, multiple paths might be displayed for a single device.

For HP-UX 11i v3, Ignite-UX will allow HP-UX system software to select the best path when a particular path is needed. For example, boot paths will be selected by system software when the boot device is selected.

Note that horizontal scrolling might be required to read the entire hardware path and associated data in Ignite-UX GUI screens.

IMPORTANT: Due to application dependencies, HP-UX software deployment tools such as Ignite-UX expect legacy DSFs to be present and the legacy naming model to be enabled. Therefore, HP recommends only partial migration be performed, as detailed in the HP-UX 11i v3 Persistent DSF Migration Guide, available at http://www.hp.com/go/hpux-core-docs.

System installation configuration

When using Ignite to install HP-UX on a client, a root disk must be identified. Ignite-UX selects a default disk, but it may be changed using the Root Disk... button on the Basic tab on the client installation configuration interface shown below.

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.
