Following are some service group dependency limitations:
A group dependency tree may be at most five levels deep.
You cannot link two service groups whose current states violate the relationship.
For example, all link requests are accepted if all instances of parent group are offline.
All link requests are rejected if parent group is online and child group is offline, except in offline dependencies and in online local soft dependencies.
All online global link requests and online remote link requests to link two parallel groups are rejected.
All online local link requests to link a parallel parent group to a failover child group are rejected.
