Interface Card OL* Support Guide

Glossary
affected card Interface cards that are in the same power domain as the target slot.
See also OL* .
affected slots The set of PCI slots, other than the target slot, that 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.
Attention Button A momentary-contact push button, located adjacent to each OL* capable slot, which you press
to initiate a hot-insertion or hot-removal at that slot.
hardware scan
An examination of all peripheral devices connected to a system, facilitated by ioscan and
saved in the kernel by the system.
HBA Host Bus Adapter
hot-insertion Physically adding a PCI card to the system while the operating system is running.
hot-pluggable A component that can be added to or removed from a system while the system remains
operational, but requires software intervention to complete the procedure.
hot-removal Physically removing a PCI card from the system while the operating system is running.
MFC multiple-function card
MRL Manual Retention Latch. Also known as a latch.
OL* A product that enables PCI I/O cards to be replaced (removed, and added) to an HP-UX computer
system designed to support this feature. OL* capable systems do not need to be completely
shut down, then rebooted, nor does a card addition or removal affect other system components.
The system hardware uses per-slot power control combined with operating system support to
enable this feature. Shorthand for OLARD

OL* functionality is provided by the olrad command in the pdweb.
See also OLRAD.
power domain A group of one or more interface card slots that are powered on or off as a single unit.
target slot The PCI slot that is directly involved in the hot-plug operation. The card is inserted into or
removed from the target slot. The operating system is responsible for halting I/O on the affected
slots and the target slot before proceeding with the hot-plug operation.
tool An application, command, or script that can be executed by pdweb on a device or slot to perform
a task.
window The main area in which application elements and controls are displayed.
X client An application or tool that displays on an X server. X clients can also be called X applications.
X server A local application that accepts X client requests and acts upon them.

across a network. It enables applications or tools to run on a remote computer.
