In this case I normally do an 'vos examine' for the volume and then
e 'vos status ' for the fileserver vos exameine showed me that the RW-volume 
lives on. If that server doesn't show any activity on behalf of the volume I 
think it's save to unlock the volume. Such a situation may be caused by a 
volserver crash or a killed vos command or a network outage during a vos command.
