Host and Application Clustering130
For information about discovering application clusters, see ”Discovering Applications, Backup Hosts
and Hosts” on page 83.
Refer to the support matrix for a complete list of supported configurations. The support matrix is
accessible from the Documentation Center (Help > Documentation Center in HP Storage Essentials).
Automatic Discovery of Host Clusters
MSCS on Windows 2003 and Veritas Clusters on Solaris support automatic discovery. To discover
hosts using either of these cluster services:
1. Discover your hosts and applications as described in ”Discovering Applications, Backup Hosts
and Hosts” on page 83. The clusters are automatically recognized by the management server.
NOTE: The following optional steps describe how to select a preferred host from which
shared resource capacity data will be collected.
2. Optional: Access Cluster Manager by right-clicking a cluster in System Manager and selecting
Edit Cluster. The Cluster Manager Overview page is displayed. Click Next.
3. Optional: Cluster Manager Step 2 (Select Preferred Host for Cluster Shared Resources) is
displayed. Select a preferred host for each of the cluster shared resources. Keeping the default
selection of “None” will result in shared resource capacity data being collected from an
available active host that shares the resource. Choosing a particular active host results in the
specified host being used for data collection. If the specified host becomes unavailable, an
available active host is used for data collection.
Specify the preferred host for individual cluster shared resources. If a resource is not shared by
the preferred host selection, the preferred host menu for that shared resource will continue to
display the previous selection.
When you have finished specifying preferred hosts, click Finish.
Manual Discovery of Host Clusters
If you are using a cluster service that doesn’t support automatic discovery, you must manually create
your clusters. For the list of cluster services that support automatic discovery, see ”Discovering
Clusters” on page 129.
NOTE: In some environments, using Cluster Manager to manually create a cluster with NetApp
hosts may result in unsuccessful or incomplete cluster creation.
To manually discover clusters:
1. Discover your hosts and applications as described in ”Discovering Applications, Backup Hosts
and Hosts” on page 83.
2. Access Cluster Manager by right-clicking a host in System Manager and selecting Build Cluster.
The Cluster Manager Overview page is displayed. Click Next.
