Starting with HP-UX 11i v3 OE Update March 2013 release, Ignite-UX supports the size of Swap, Dump, and unused logical volumes up to 1 TB instead of the previous limit of 128 GB on 11i v2 and 11i v3. During a cold installation or recovery, larger amounts of swap, dump, or swap volumes can be utilized in disk or volume groups by defining multiple swap, dump, or swap volumes. The limit for unused volumes on 11i v1 is 1 TB; however, the limit for swap and dump has not been increased.

Identifying devices for other tasks

There are a number of other Ignite tasks that require the identification of I/O devices:

•When building installation media, you must use the ioscan command to find the tape, CD, or DVD drive. Note that some of the CD/DVD writing SW included with Ignite-UX but not developed by HP only works with legacy device special files.

•When performing a system recovery on Itanium-based systems, you must find the tape device’s hardware path to create an EFI boot option. (This must be done at the time the tape is created.)

•During two-step media recovery, you must select the hardware path of the tape drive to recover from.

•When in expert recovery mode, you must have the hardware path of the disk you are attempting to recover.

•When identifying disks in configuration files to define them or combine them in a single volume group, you must supply the hardware paths of the disks.

Important characteristics of the agile view

The following points will help you move from the legacy view to the agile view:

•When using the new persistent DSFs, be sure to use the new directory structure: Table 3 Mass storage DSF directories

Persistent DSF Directory

Legacy DSF Directory

/dev/disk

/dev/dsk

/dev/rdisk

/dev/rdsk

/dev/rtape

/dev/rmt

•Both legacy and persistent DSFs can be created during installation and recovery of HP-UX 11i v3 depending on your volume manager. When Ignite-UX creates file system content for HP-UX 11i v3, persistent DSFs are used for LVM volumes and VxVM 5.0 layout, and legacy DSFs are used for VxVM 4.1.

NOTE: The VxVM components in the Ignite-UX install environment and the installation depot must be version 5.0 or higher in order to use persistent DSFs.

•Keep in mind that persistent DSFs endure with recovery if Ignite recovers to the same hardware or can map to replacement hardware, but are not guaranteed to remain the same between installations. See Figure 25 for an overview regarding consistency of I/O addressing.

•If hardware is replaced and recovery is not needed, you might want to run io_redirect_dsf to correct the system configuration. For more information, see io_redirect_dsf(1M).

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.
