Introduction; Overview - HP Integrity Superdome 2 16-socket User Manual

1 Introduction

Overview

HP Superdome 2 Onboard Administrator is the complex management processor, subsystem, and
firmware base used to support HP Integrity Superdome 2 complexes and all the managed devices
contained within the complex.
Onboard Administrator provides a single point from which to perform basic management tasks
for the following complex devices:
Compute enclosures
IOXs
Server blades
I/O interconnects
Onboard Administrator performs configuration steps for the complex, enables run-time management
and configuration of the complex components, and informs you of problems within the complex
through email, SNMP, or the Insight Display.
HP recommends that you read the HP Integrity Superdome 2 User Service Guide for complex
specific information before proceeding with the Onboard Administrator setup.
This user guide provides information on the following topics:
Initial setup and operation of the HP Superdome 2 Onboard Administrator
Use of the Onboard Administrator GUI
Use of the compute enclosure Insight Display
Initial setup and operation of the HP Superdome 2 Door Status Display
The HP Integrity Superdome 2 Onboard Administrator Command Line Interface User Guide covers
the use of the CLI.
The HP Superdome 2 Onboard Administrator provides several features designed to simplify
management of Superdome 2 enclosures, blades, and interconnects. Compute enclosures within
a Superdome 2 complex can be configured with redundant Onboard Administrator modules to
provide uninterrupted manageability of the entire complex in the event of a failure of a single
Onboard Administrator module.
The following table lists which Onboard Administrator feature is enhanced when an enclosure
contains redundant Onboard Administrator modules. For an enclosure with only a single Onboard
Administrator module, the table indicates the behavior of the enclosure if the single Onboard
Administrator module has failed or is removed.
