The chapter provides step-by-step instructions on how to configure eDirectory and Identity Manager into a supported SUSE Linux Enterprise Server (SLES) cluster environment with shared storage and an example of a clustered Identity Manager deployment.
For a production-level Linux High Availability (HA) solution with shared storage, implementing a fencing mechanism in the cluster is recommended. Although there are different methods of implementing fencing mechanisms in the cluster, in our example, we use a STONITH resource which uses the Split Brain Detector (SBD).
Figure 17-1 shows a sample cluster deployment solution.
