6027-1630 The GPFS cluster data on nodeName is back level.
Explanation
A GPFS™ command
attempted to commit changes to the GPFS cluster
configuration data, but the data on the server is already at a higher
level. This can happen if the GPFS cluster
configuration files were altered outside the GPFS environment, or if the mmchcluster command
did not complete successfully.
User response
Correct any problems and reissue the command. If
the problem persists, issue the mmrefresh -f -a command.
