Hi,
I think the API you are looking for is dfm-related-objects-list-info.
You'll have to pass as parameter the name of the node and it will return you data about its parent (the parent-cluster in this case).
Example Input :
<dfm-related-objects-list-info>
<object-name-or-id>clus_2-01</object-name-or-id>
</dfm-related-objects-list-info>
Example Output :
<parent-object-list>
<parent-object>
<name>clus_2</name>
<id>3846</id>
<full-name>clus_2</full-name>
<type>cluster</type>
</parent-object>
</parent-object-list>
<child-count-list>
<child-count>
<count>1</count>
<type>aggregate</type>
</child-count>
</child-count-list>
Hope this helps.
Best Regards
