Use this command to define a collocation group. A collocation group is a group of nodes or file spaces on a node whose data is collocated on a minimal number of sequential access volumes. Their data is collocated only if the storage pool definition is set to collocate by group (COLLOCATE=GROUP).
To issue this command, you must have system or unrestricted storage privilege.
