Table 5 I/O Configuration variables (continued)

I/O Configuration Variable	Description
_hp_hide_other_disks	(string) This may be set to one or more space-separated hardware paths of disks that
	must be “hidden” from being configured or otherwise modified during the installation.
	This is useful for hiding multiple disks.
hw_instance_number	(string) Setting this keyword forces a specific instance number assignment for the
	specified hardware device. This is useful for producing client configurations consistent
	with others regardless of variations in hardware configurations.
inventory_block_path	(string) This keyword is used to control Ignite inventory functionality by instructing Ignite
	to not collect inventory information for the devices specified. This is useful when you
	want devices hidden and not available for selection during installation.
inventory_block_protocols	(string) This keyword is used to control Ignite inventory functionality by instructing Ignite
	to not collect inventory information for the devices of the protocol type specified. This
	is useful when you want to increase the performance of the I/O inventory process by
	ignoring all devices of a certain protocol. These devices will not be available for
	selection during installation.

Below are listed the value types for use with the I/O configuration variables.

Table 6 I/O Configuration value types

I/O Configuration Value Type	Description
Hardware Path	For keywords that take a hardware path as an index parameter or value, the hardware
	path may be a series of more than one decimal or hexadecimal numbers separated
	by the period ( . ) or the forward slash ( / ) characters. A complex string or string
	variable may also be used where a hardware path is expected.
Physical Location	A physical location may be a series of alphanumeric values separated by the colon (
	: ) character.
World-Wide Name / WWID	The format of this value varies depending on the protocol and device. This value is
	often a standard IEEE value in hexadecimal format, however this value may have some
	other format. This value may not contain white space.
I/O Protocol	The valid protocol values are:
	•	fibre_channel
	•	parallel_scsi
	•	sas
	•	usb

What are the requirements for the use of persistent DSFs? Must I use them exclusively or can I mix them with legacy DSFs?

Ignite-UX will use persistent DSFs for installation and recovery on systems running HP-UX 11i v3. Internally, VxVM volume management software controlling installation and recovery uses persistent or legacy DSFs as appropriate for the VxVM version used. See “Important characteristics of the agile view” (page 78) for more information.

Can the user switch from persistent to legacy DSFs and back if desired?

Switching between persistent and legacy DSFs is specific to the volume manager. See your volume manager documentation for more details.

Does the Ignite–UX interface enforce a particular use model with respect to persistent and legacy DSFs?

No, but persistent DSFs will be used for HP-UX 11i v3 installation and recovery.

If a persistent DSF is specified, is the equivalent legacy DSF added as well? And vice versa?

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.
