Cluster Resource node

A Cluster Resource node represents finer details about the configuration of the clustered service. A cluster resource can be a shared storage that is used by the service or a software that is used to implement the service. For example, the clustered Microsoft SQL Server service contains a SQL Server resource and a SQL Server Agent resource.

Each instance of the Cluster Resource node can contain any number of attributes, which will be used to match SIs to Cluster Services later on. Cluster Resource nodes are fully owned and controlled by BMC Discovery patterns. For detailed information about patterns, see the The Pattern Language TPL and Configipedia.

Cluster Resource node lifecycle

The following section describes the scenarios in which a Cluster Resource 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 is automatically created to the Cluster Service node to identify the services running on the cluster resource. The generated key for a Cluster Resource node is entirely dependent on the kind of Cluster. 

Update

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

Remove

You can remove a Cluster Resource node manually or automatically. The Cluster Resource node is removed automatically when the Cluster Member node is removed through a cascade removal. Alternatively, the Cluster Resource 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 Resource node:

1. Search for the necessary Cluster Member.
2. List the resources for the selected Cluster Member node.
3. Select the Cluster Resource from the list
4. Pick Destroy from the Actions list.
