The SMS menus are useful to define the operating system installation method, choosing the
installation boot device, or setting the boot device priority list for a fully managed server or a
logical partition. In the case of a network boot, SMS menus are provided to set up the network
parameters and network adapter IP address.

HMC
The Hardware Management Console is a system that controls managed systems, including
IBM System p5 hardware, logical partitions, and Capacity on Demand. To provide flexibility
and availability, there are different ways to implement HMCs, including a local HMC, remote
HMC, redundant HMC, and the Web-based System Manager Remote Client.

Local HMC
A local HMC is any physical HMC that is directly connected to the server that it manages
through a private service network. An HMC in a private service network can be a Dynamic
Host Control Protocol (DHCP) server from which the managed server obtains the address for
its firmware. Additional local HMCs in your private service network cannot be other DHCP
servers, but they can be DHCP clients.

servers, but they can be DHCP clients.
Remote HMC
A remote HMC is a stand-alone HMC or an HMC installed in a rack that is used to access
another HMC remotely. A remote HMC can be present in an open network.
another HMC remotely. A remote HMC can be present in an open network.
Redundant HMC
A redundant HMC manages a server that is already managed by another HMC. When two
HMCs manage one server, those HMCs are peers and can be used simultaneously to
manage the server. The redundant HMC in your private service network is usually a DHCP
client.

Web-based System Manager Remote Client
The Web-based System Manager Remote Client is an application that you typically installed
on a PC and you can download directly from an installed HMC. After you have installed an
HMC, and you have assigned HMC Ethernet IP addresses, you can download the
Web-based System Manager Remote Client from a Web browser, using the following URL:

You can then use the PC to access other HMCs remotely. Web-based System Manager
Remote Clients can be present in private and open networks. You can perform most
management tasks using the Web-based System Manager Remote Client.

to access your managed systems (including HMCs) from multiple locations using multiple
HMCs.

Open Firmware
An IBM System p5 server has one instance of Open Firmware both when used in the
partitioned environment and when running as a full system partition. Open Firmware has
access to all devices and data in the server. Open Firmware is started when the server goes
