If the existing resource property attributes do not satisfy the validation conditions of the new version of the resource type, the cluster administrator must provide valid values.
The cluster administrator must provide valid values under the following conditions:
When the new version of the resource type does not have a default value and uses a property that is not declared in the earlier version.
When the existing resource uses a property whose value is undeclared or invalid in the new version. Declared properties that are undeclared in a new version of a resource type are deleted from the resource.
Any attempt to upgrade from an unsupported version of a resource type fails.
After an upgrade, resources inherit the resource property attributes for all properties from the new version of the resource type.
If you change the default value of a resource type in the RTR file, the new default value is inherited by existing resources. The new default value is inherited even if the property is declared tunable only AT_CREATION or WHEN_DISABLED. A property of the same type that the cluster administrator creates also inherits this default value. However, if the cluster administrator specifies a new default value for the property, the new default value overrides the default value that is specified in the RTR file.
Note - The cluster administrator can overcome this limitation by specifying values for the properties and thus overriding the defaults.
