This warning may be issued if the relabeling operation attempts to relabel the same volume as another library volume operation: LABEL LIBVOLUME, CHECKIN LIBVOLUME, CHECKOUT LIBVOLUME, or another relabeling operation. For example, suppose two relabeling operations run on the same volume. If the first relabeling operation succeeds and the second operation fails, no action is required.

Verify the volume is still checked into the library with the QUERY LIBVOL command. If it is not checked in, use LABEL LIBVOL or CHECKIN LIBVOL to check the volume back into the library.
