HP e3000 PA-8700 A-Class and N-Class Core I/O Card

By John Spitzer, Commercial Systems Division

Introduction

MPE/iX release 7.5 introduces support for the HP e3000 PA-8700 N-Class and A-Class hardware platforms.

The Core I/O card is one of the hardware components of these platforms that has undergone significant

improvement. There are changes to both the hardware and the I/O paths used to access the console and the

functions of the Core I/O card. This article describes how these changes affect console commands and

operations.

The Core I/O card is a component installed in the systems and contains all the I/O components necessary to

configure a bootable system (not including disks and tapes drives and terminals). The Guardian Service

Processor (GSP) is an independent support processor built into the N-Class and A-class Core I/O. The GSP

provides the functionality required for basic console operations to control the hardware before the OS is

booted and provides the connectivity and major system manageability features for the system.

You will see two significant changes to the Core I/O card for the PA-8700 platforms:

• The I/O paths used to configure the logical devices on the Core I/O card have changed.

• The GSP now incorporates a version of the Secure Web Console into the firmware.

This article also contains information on other enhancements related to the console and additional

information on the usage of some command and functions that are available on both Core I/O I and Core I/O

II.

Configuration of Console I/O Paths

The following data shows the details of the information that needs to be added to the IO configuration in

Sysgen in order to configure the core I/O serial devices. The ldev 20 configuration is shown. The

configurations of the remote session and UPS devices are the same except for the PATH and LDEV parameters.

Additionally, the UPS port requires the class HPUPSDEV to be assigned. These entries are the same as the

corresponding entries on the earlier N and A Class systems except the I/O path has changed.
