SCO UnixWare
Supported PCI Functionality
Compaq support of PCI Hot Plug under UnixWare 7.01 provides hot
replacement, hot upgrade, and hot addition for a variety of boards. You can
eliminate downtime when you replace faulty adapters, upgrade your systems,
and dynamically add new adapters.
Software Components
The primary software components for hot-plug support include:
Hot-plug Admin Manager user interface


Hot-plug Controller interface


Netscape AutoConfig Subsystem


Hot-plug system and device drivers


Device Driver Interface (DDI-8) specification


The Admin Manager is the graphical user interface for PCI Hot Plug
technology. All user commands to add, remove, or replace an adapter funnel
through the Admin Manager. The Hot Plug Admin Manager is incorporated
into SCO's existing system-managed framework called SCO Admin.
The Hot Plug Controller interface tracks system component information and
manages the actions required for hot-plug functions. The Hot Plug Controller
Interface processes Hot Plug Services Library (HPSL) requests by interfacing
with the Netscape AutoConfig Subsystem. Using the existing Compaq Support
Software 2.1, auto-configuring framework hot-plug events will be handled
through the resource manager database, which has been updated for
dynamically loading and unloading individual device drivers.
The device driver interface specification defines how device drivers
communicate with the UnixWare operating system and hot-plug software.
SCO's Device Driver Interface version 8 (DDI-8) and other device driver
interfaces are enhanced to provide the functions for adding or removing driver
instances and suspending or resuming operation in conjunction with hot-plug
operations.
