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 297. 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 341.

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 297.

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.

3.Cluster Manager Step 2 (Specify Cluster Properties and Cluster Members) is displayed. If you are discovering an HP Serviceguard cluster, this page may already be populated, and you can skip to the next step. If this page isn’t already populated, follow these steps to specify the cluster properties and cluster members:

a.In the Cluster Properties section, specify the cluster name, cluster server, and cluster virtual IP.
