First, make sure that all nodes are part of a group, because when you use collocation by group, if a node is not a member of a group, then that node is its own group. This is a common mistake which ends up consuming a lot of tapes.
You can use this command to get a list of all nodes that do not belong to a collocation group:
Code:
select domain_name,node_name from nodes where collocgroup_name is null
For each node that is not in a group, you will need to do add them to a group (unless they need to stay by themself):
Code:
define collocmember {collocgroup_name} {node_name}
For those that are already in a group, but want them into a different group, it will be a 2 step process, first remove them from the current group and then add them to the new group:
Code:
delete collocmember {current_collocgroup_name} {node_name}
define collocmember {new_collocgroup_name} {node_name}
