46 Logical Partitions on System i5
3.1 HMC concepts and initial setup
The main functions of the HMC are to perform logical partitioning functions, service functions,
and various system management functions. The partitioning functions and some of the
servicing functions, which were previously in the iSeries service tools, will now be performed
by functions in the HMC for partitioned systems. The HMC can be used to manage from one
to two partitioned systems. Other highlights of the HMC are as follows:
򐂰 The HMC connects to the managed system or systems via an ethernet LAN connection.
򐂰 It runs a Java™ based application running in an embedded OS.
򐂰 The user is only able to access the management applications via a GUI interface.
򐂰 The HMC can be run remotely via a Web-based System Management Remote Client
running on a Windows based PC or a Linux based PC.
򐂰 A virtual console terminal can be configured to run on the HMC for each partition, thus
reducing the need for extra hardware in each partition. One of these console types is
5250.
򐂰 We recommend that you configure a second HMC for redundancy. This second HMC
cannot actively manage the same server at this release.
3.1.1 HMC and Service Processor levels, and information sources
When you are preparing to install or maintain your HMC and/or the services processor on the
System i5, you should review the following chart for the corresponding system firmware levels
(Figure 3-1).
