Hmc Setup; The Hmc Logical Communications - IBM p5 590 System Handbook

– It can also be operated remotely using the command line interface through
an SSH connection to the HMC.
A virtual console terminal can be configured to run on the HMC for each
partition reducing the need for extra hardware in each partition.
We recommend that a second HMC be configured for redundancy. Either HMC
can actively manage the same managed systems.

8.2 HMC setup

To successfully configure the HMC, you must understand concepts, make
decisions, and prepare information. Depending on the level of customizing you
intend to apply to your HMC configuration, you have several options for setting up
your HMC to suit your needs.
Depending on the system that is being installed, some of the HMC setup is
Customer Set Up (CSU). The IBM Service Support Representative (SSR)
installing the system will perform some of the HMC setup steps and the client will
perform the remainder of the steps. It is typical that system partitioning, resource
assignment, and other policies be defined by the client.
When a new system or an upgrade is delivered it will have a document named
Start Here for hardware. This document is the starting point for setting up the
system and the HMC. A CD named the IBM Sserver Hardware Information
Center is included to provide information about the server, the HMC, and other
Sserver p5 related topics.
The most current version of this information can be accessed directly off the
Web. The following is the URL for the US English North American Information
Center.

8.2.1 The HMC logical communications

The following sections describe the communications that are possible.
HMC to managed system
HMC to manage system is a type of communication that is used to perform most
of the hardware management functions where the HMC issues control function
requests through the service processor of the managed system.
