reasons. If no laptop is available, an ASCII terminal can be used on the native
serial port to access the FSP menus in character mode.
Open networks are used for communications between a logical partition and the
HMC. This connection is largely to facilitate traffic over the Resource Monitoring
and Control (RMC) subsystem, which is the backbone of Service Focal Point
(SFP) and required for dynamic resource allocation. The open network also is the
means by which remote workstations may access the HMC, and it could be the
path by which an HMC communicates with IBM Service through an Internet
connection.
Regardless of which type of network is involved, customers must provide their
own networking infrastructure, such as cables, switches or hubs. Switches that
support virtual networks (VLAN) may be used to create one or more private or
open networks, as conditions require.
2.6 Customer Setup
The HMC running in a System p5 environment is a customer setup machine.
Customers can purchase an IBM Machine Control Program Remote Support
Agreement (MCPRSA) that provides phone technical support for routine
installation, configuration and how-to questions. Contracts can be purchased for
one- and three-year periods. The agreement covers the cost of all Licensed
Machine Code upgrades during the contract. Hardware service contracts for on-
site hardware support are available beyond the initial warranty period.
Customers are responsible for installing and updating the Licensed Machine Code
on all HMCs and System p5 managed servers. We will discuss an update strategy
in detail later. Systems administrators should become familiar with the
information and tools available on the HMC support home page:
http://www14.software.ibm.com/webapp/set2/sas/f/hmc/home.html
The systems administrator should use the link on the above URL to sign up for
subscription services. This enables an administrator to receive email notification
of new releases of software and firmware. Knowing what is current is essential to
correctly and successfully managing System p5 servers and the HMC.
2.7 Documentation
Documentation for the IBM System p5 and i5 servers and the HMC is available
through the IBM Systems Hardware Information Center. This is a browser-
oriented information retrieval application that can be installed on servers and
workstations, but which also is accessible over the Internet.
