While processing an AUDIT LIBRARY command for the given library, multiple physical volumes are found to have the same name.
The first instance of the volume is retained in the server inventory; all other instances are ignored.
Remove all of the redundant instances of the volume from the library. If the volume which the server retained is found to be the incorrect one, it can be checked out with the CHECKOUT LIBVOLUME command; then the correct instance can be checked into the library with a CHECKIN LIBVOLUME command.
