In this figure, the box on the left of the topology canvas shows a cluster with two hosts, and the box on the right shows a cluster with four hosts. Both clusters are in the expanded view mode, so all of the nodes are displayed. To minimize the view of a cluster, click the (-) button.

Figure 19 System Manager Cluster Representation

In the minimized view of a cluster, all of the nodes of the cluster are collapsed into a single box. To expand the display to show all of the nodes, click on the (+) button.

In the minimized view, a dotted line from an application to a cluster indicates that the application only runs on some of the clustered hosts. A solid line indicates that the application runs on all of the clustered hosts.

Double-click a cluster to open the Properties page for the cluster. Double-click an individual cluster node to open the Properties page for that node.

Clustering in Topology

Element topology expands System Manager’s view to show exactly which shared resources a particular application instance uses. Individual paths from application nodes are listed in the path tree as well.

For detailed information about viewing element topology, see ”Viewing Element Topology” on page 437.
