6027-1007 attribute found in common multiple times: attribute.
Explanation
The attribute specified on the command line is in
the main input stream multiple times. This is occasionally legal,
such as with the trace attribute. These attributes, however, are not
meant to be repaired by mmfixcfg.
User response
Fix the configuration file (mmfs.cfg or mmfscfg1 in
the SDR). All attributes modified by GPFS™ configuration
commands may appear only once in common sections of the configuration
file.
