Hardware Management Console
(HMC) Case Configuration Study for
LPAR Management
This IBM® Redpaper provides Hardware Management Console (HMC)
configuration considerations and describes case studies about how to use the
HMC in a production environment. This document does not describe how to
install the HMC or how to set up LPARs. We assume you are familiar with the
HMC. Rather, the case studies presented in this Redpaper provide a framework
to implement some of the more useful HMC concepts. It provides examples to
give you ideas on how to exploit the capabilities of the HMC.
The topics discussed in this Redpaper are:
򐂰 Basic HMC considerations
򐂰 Partitioning considerations
򐂰 Takeover case study:
– Description of the scenario
– Setting up remote ssh connection to the HMC
– Using the HMC to perform CoD operations
– Examples of dynamic LPAR operations
– Using micropartitioning features
– Security considerations
