After the preparations are done, the following steps are necessary to install and set up a cluster with SUSE® Linux Enterprise High Availability Extension:
Installing SUSE® Linux Enterprise Server 11 and SUSE® Linux Enterprise High Availability Extension 11 as add-on on top of SUSE Linux Enterprise Server. For detailed information, see Section 3.1, “Installing the High Availability Extension”.
Configuring OpenAIS. For detailed information, see Section 3.2, “Initial Cluster Setup”.
Starting OpenAIS and monitoring the cluster status. For detailed information, see Section 3.3, “Bringing the Cluster Online”.
Adding and configuring cluster resources, either with a graphical user interface (GUI) or from command line. For detailed information, see Chapter 4, Configuring Cluster Resources with the GUI or Chapter 5, Configuring Cluster Resources From Command Line.
To protect your data from possible corruption by means of fencing and STONITH, make sure to configure STONITH devices as resources. For detailed information, see Chapter 8, Fencing and STONITH.
You might also need to create file systems on a shared disk (Storage Area Network, SAN) if they do not already exist and, if necessary, configure those file systems as cluster resources.
Both cluster-aware (OCFS 2) and non-cluster-aware file systems can be configured with the High Availability Extension. If needed, you can also make use of data replication with DRBD. For detailed information, see Part III, “Storage and Data Replication”.
