Clustering in System Manager
System Manager has been enhanced to seamlessly support clusters in all areas. You can view
connectivity information from all levels on a single canvas — from applications running on clusters,
to the storage array spindles that share volumes for all the nodes of a cluster.
For detailed information about System Manager, see ”
Viewing Element Topology and Properties ”
on page 249.
The following figure shows how clusters are displayed in System Manager. Note that the tree nodes
on the List tab reflect the structure of the clusters.
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 17 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.
