Cluster Member node

A Cluster Member node represents a host member in your clustering environment. The node contains the IP address of the member, which is used to link the Cluster Member to a host. Cluster Member nodes are fully owned and controlled by BMC Discovery patterns.

For detailed information about patterns, see the The Pattern Language TPL and Configipedia.

Cluster Member node lifecycle

The following section describes the scenarios in which a Cluster Member node is created, updated, or removed.

Create

The Cluster Member node is created by patterns when it detects a host in a cluster configuration during the discovery scan. A relationship link to the Cluster node to which the cluster member belongs is automatically created. Another relationship is created to the Cluster Services nodes to determine the services that are running on the cluster member at any given time.

The generated key for a Cluster Member node is entirely dependent on the kind of Cluster.

Update

The update procedure for a Cluster Member node is also fully owned and controlled by patterns. When the pattern identifies a cluster resource, it calculates a key. If a Cluster Member node with that key already exists, the node is updated accordingly.

Remove

You can remove a Cluster Member node manually or automatically. The Cluster Member node is removed automatically when the Cluster node is removed through a cascade removal. Alternatively, the Cluster Member node is removed by the pattern if the Cluster Member is physically or logically removed from the configuration. For more information about cascade removal, see Cascade Removal.

To manually remove a Cluster Member node:

Search for the necessary Cluster Member.
Select the Cluster Member from the list.
Pick Destroy from the Actions list.
