Symptom:
When you do an fndestroy or fnunbind on certain names that you know do not exist, you receive no indication that the operation failed.
Possible Cause:
The operation did not fail. The semantics of fndestroy and fnunbind are that if the terminal name is not bound, the operation returns success.
Diagnosis:
Run the fnlookup command on the name. You should receive the message, “name not found.”
Solution:
Not applicable.
