>From Tsm Admin Reference: "GRoup Specifies that collocation is enabled at the group level for client nodes. The server attempts to put data for nodes that belong to the same collocation group on as few volumes as possible. If the nodes in the collocation group have multiple file spaces, the server does not attempt to collocate those file spaces. If you specify COLLOCATE=GROUP but do not define any collocation groups or if you specify COLLOCATE=GROUP but do not add nodes to a collocation group, data is collocated by node. Be sure to consider tape usage when organizing client nodes into collocation groups"

Does that mean it does no collocation if no collocaton groups are defined? Or does it collocate by node? We have a stgpool with collocaton=group but no collocaton groups defined and tape utilization is very low. Should we set collocation=no? Hans Chr.
