Glossary

A menu selection resulting in a task or command being executed by the application.

Interface cards and the card slots they reside in which are in the same power domain as the target slot.

The set of PCI slots, other than the target slot, that would have their PCI bus disrupted as a result of a hot plug operation. This disruption includes anything that would interfere with bus traffic, including events like a bus reset or a loss of bus power. The operating system must quiesce I/O on the affected slots and the target slot before proceeding with the hot plug operation.

A momentary-contact push button, located adjacent to each hot-plug slot, that is pressed by the user to initiate a hot-insertion or hot-removal at that slot.

The section at the top of the graphical user interface screen that provides information and the ability to log off Peripheral Device Tool.

A trusted third-party organization or company that issues digital certificates used to create digital signatures and public-private key pairs.

The set of commands that can be executed directly from the operating system's command shell.

The combination of a graphic symbol and a portion program code that performs a specific function used in a graphical user interface, e.g. a scrollbar or button.

A technology used to validate a transaction's sender. This technology uses private-keys to digitally sign the data, and public-keys to verify the sender.

A program interface that takes advantage of the computer's graphics capabilities to make the program easier to use. The Peripheral Device Tool GUI is Web-enabled and displays in a Web browser.

An examination of all peripheral devices connected to a system, facilitated by ioscan(1M) and saved in the kernel by the system.

Host Bus Adapter

Physically adding a PCI card to the system while the operating system is running.

Physically removing a PCI card from the system while the operating system is running.

An item is hot-pluggable if it can be added to or removed from a system while the system remains operational, but requires software intervention to do the operation.

All of the addresses of the interface hardware and the physical path to reach each device. It is constructed top down from where the device is physically attached to the system and includes all internal and leaf nodes. All information is gathered via the use of the ioscan(1M) command.

The process of, or equipment used in, transmitting information to or from the computer.

Any device, or node, within an I/O Tree that is not the last device in the tree.

The device that is at the end, or last device, of a given I/O tree.

A semiconductor device through which current can go in only one direction to produce a visible light that acts as an indicator.

Multiple-function Card

Manually operated retention latch. Also known as latch.

Shorthand for OLAR

The ability of a PCI I/O card to be replaced (removed and/or added) to an HP-UX computer system designed to support this feature without the need for completely shutting down, then re-booting the system or unnecessarily affecting other system components. The system hardware uses per-slot power control combined with operating system support to enable this feature.

Name of a tab in the pdweb GUI, OLRAD Cards. The “D” is for a future capability to Delete a slot. This feature is not supported at this time.

The OL* functionality is provided by the olrad command in the Peripheral Device Tool, pdweb.

Operating System

An enhanced version of PCI.

A standard for the connection between a processor and attached devices.

A grouping of one or more interface card slots that are powered on or off as a unit.

A control that moves the view of the data displayed in the window.

A security protocol that encrypts and authenticates transactions between the client and the server. It is application protocol independent.

A protocol of the Internet reference model used for network management.

A login identity that enables special permissions for modifying system files that most users do not have permission to modify. Superuser is also called “the root user” or “root” because the user ID for superuser is root.

The interface card to be added or replaced using OL*, and the card slot it resides in.

The PCI slot that is directly involved in the hot plug operation. The card will be inserted into or removed from the target slot. The operating system is responsible for quiescing I/O on the affected slots and the target slot before proceeding with the hot plug operation.

An application, command, or script that can be executed by Peripheral Device Tool on a device or slot to perform a task.

The main area in which application elements and controls are displayed.

An application or tool that displays on an X server. X clients can also be called X applications.

A local application that accepts X client requests and acts upon them.

A cross-platform windowing system that uses the client/server model to distribute services across a network. It enables applications or tools to run on a remote computer.
