Chapter 1Planning to Install the Hardware
Before you install any hardware for your cluster, you must
make a few decisions. Decide on the purpose and the hardware configuration
of the cluster, and choose the installation method. Include nodes in your
cluster plan that you might want to add to the cluster in the future. These
decisions can save you time when you begin installing the hardware and software
for the cluster.
To plan the process of installing the hardware for your cluster, see
these sections:
Planning the Installation
The Foundation Services product provides two ways of installing software on the
cluster:
Installation using the nhinstall tool. The nhinstall tool enables you to install
the Foundation Services on a cluster. This tool is flexible and provides various configuration
options that you can adapt to your requirements. However, the nhinstall tool only supports the installation of master-eligible nodes and
diskless nodes. You can only install dataless nodes manually.
Manual installation. You can
manually install software on a cluster containing master-eligible nodes, diskless
nodes, and dataless nodes.
Manual installation provides more flexibility when installing components
of the Foundation Services. However, a manual installation can result in a cluster configuration
that is not easily reproducible on other clusters.
Installing the Hardware (Task Map)
The following table outlines the tasks for choosing and installing the
cluster hardware and the installation hardware:
Task | Description | For Instructions |
Choose the installation method. | Choose the method
for installing the Foundation Services on the cluster. | Netra High Availability Suite Foundation Services 2.1 6/03 Overview |
Choose the hardware configuration
of your cluster. | Choose the number and type of nodes of the cluster. Try to include nodes that
you might want to add to the cluster in the future. | Chapter 2, Choosing the Cluster Hardware |
Install the cluster hardware. | Install the cluster
nodes, the Ethernet switches, and the terminal server. | Chapter 3, Installing and Configuring the Cluster Hardware |
Install the installation server. | The installation
server is required for any installation method you choose. | Installation Server |
Install the development host. | If you are planning
to develop applications using the Foundation Services API, install a development host. | Development Host |
Connect the cluster. | Connect the cluster nodes to the
Ethernet switches and the terminal server. Connect the installation server
and, if necessary, the development host, to the cluster. | Connecting the Hardware for Installation |
