For example,if Host resource “HostB” has a relationship with user resource “Watson”
the relationship will appear in the relationship list of both resources. If you display the
relationships for resource HostB, and remove the relationship with user Watson, the
relationship will be removed from the relationship lists of both HostB and Watson.

the Grouping Manager window.
If you attempt to begin a different operation or leave the Grouping Manager applet

However, you can add and remove relationships and attributes in multiple operations
on the resource you’ve selected before you save.

removed from the other resources involved.
