*******                                                        
Dynamically removing a Virtual Fibre Channel client adapter that
attaches at least one tape device may fail.                    

Problem Conclusion

A race condition in the internal deactivation processing of the
tape device driver(s) and the virtual client adapter driver may
result in the adapter never completing deactivation/removal. The
virtual adapter Licensed Internal Code will be changed to      
prevent this condition from blocking removal completion.
