Cluster attributes 

Attributes that define the cluster.  

For example, ClusterName and ClusterAddress.  

Service group attributes 

Attributes that define a service group in the cluster.  

For example, Administrators and ClusterList.  

System attributes 

Attributes that define the system in the cluster.  

For example, Capacity and Limits.  

Resource type attributes 

Attributes that define the resource types in VCS. These can be further classified as: 

• Type-independent—Attributes that all agents (or resource types) understand. Examples: RestartLimit and MonitorInterval; these can be set for any resource type.

  Typically, these attributes are set for all resources of a specific type. For example, setting MonitorInterval for the IP resource type affects all IP resources.

• Type-dependent—Attributes that apply to a particular resource type. These attributes appear in the type definition file (types.cf) for the agent.

  Example: The Address attribute applies only to the IP resource type.

  Attributes defined in the file types.cf apply to all resources of a particular resource type. Defining these attributes in the main.cf file overrides the values in the types.cf file for a specific resource.

  For example, setting StartVolumes = 1 for the DiskGroup types.cf defaults StartVolumes to True for all DiskGroup resources. Setting the value in main.cf overrides the value on a per-resource basis.

• Static—These attributes apply for every resource of a particular type. These attributes are prefixed with the term static and are not included in the resource's argument list. You can override some static attributes and assign them resource-specific values.

  See Overriding resource type static attributes.

Resource attributes 

Attributes that define a specific resource.  

Some of these attributes are type-independent. For example, you can configure the Critical attribute for any resource.  

Some resource attributes are type-dependent. For example, the Address attribute defines the IP address associated with the IP resource. These attributes are defined in the main.cf file.
