Chapter 1: Overview of the Installation Process


This chapter provides an overview of the installation process, and presupposes that you have completed the planning process as described in the Planning Guide. This chapter contains the following sections:

  • Overview of the Installation Tasks
  • Overview of the Cluster Creation Tasks
  • Overview of the Migration Tasks
  • Where to Find Documentation.
  • Overview of the Installation Tasks

    After completing the planning steps, you are ready to install the HACMP software. This section provides an overview of the installation process.

    Step 1: Installing HACMP on Server Nodes

    In this step, you install HACMP on all server nodes. Chapter 4: Installing HACMP on Server Nodes describes this step of the installation process.

    Step 2: Installing HACMP on Client Nodes

    In this step, you install HACMP on all client nodes. Chapter 5: Installing HACMP on Client Nodes describes this step of the installation process.

    After installing HACMP, you are ready to create an HACMP cluster.

    Overview of the Cluster Creation Tasks

    After installing the HACMP software, you are ready to create an HACMP cluster. This section provides an overview of the cluster creation process.

    Step 1: Creating an HACMP Cluster

    HACMP supplies the following utilities that enable you to quickly create a cluster:

  • Online Planning Worksheets
  • Two-Node Cluster Configuration Assistant
  • WebSphere, DB2 UDB or Oracle Smart Assists.
  • Using the Online Planning Worksheets Application

    During the cluster-planning process, the Online Planning Worksheets application enables you to enter configuration data and save it to a cluster definition file. At the end of the planning process, you can use the cluster definition file to immediately configure your cluster. For information about Online Planning Worksheets, see the chapter on Using Online Planning Worksheets in the Planning Guide.

    Using the Two-Node Cluster Configuration Assistant

    You can easily create a basic two-node cluster using the Two-Node Cluster Configuration Assistant. For information about the Two-Node Cluster Configuration Assistant, see Chapter 9: Creating a Basic HACMP Cluster.

    Using Smart Assist for WebSphere, DB2 or Oracle

    You can also configure a cluster with a WebSphere, DB2 UDB, or Oracle application. For information, see the corresponding HACMP Smart Assist guide.

    Step 2: Configuring an HACMP Cluster

    In this step, you perform tasks as described in the following chapters:

  • Chapter 6: Configuring Installed Hardware
  • Chapter 7: Defining Shared LVM Components
  • Chapter 8: Configuring AIX 5L for HACMP
  • After you create a basic cluster and configured supporting components, you are ready to configure and monitor your cluster as described in the Administration Guide.

    Overview of the Migration Tasks

    If you are migrating an existing installation of HACMP, follow the instructions from Chapter 3: Upgrading an HACMP Cluster, and refer to Chapter 4: Installing HACMP on Server Nodes as needed.

    Where to Find Documentation

    All documentation is install in the directory:

    /usr/share/man/info/en_US/cluster/HAES
