Ciscoworks Expert needed--RME show IP address instead of hostnames

Question

Please take a look at the pics,
In RME and many other modules, it display the IP addresses , instead of the Hostnames as the ID for the devices(we want to use the hostnames for the devices). I saw the settings at Common Service/Global Setting was at IP(see the attach pictures). I then changed it into SysName and rediscover the devices. It didn’t work. It shows the same thing.
Anyone can advise me how to correct it?
thanks,
Han

it seems you are seeing the following 2 bugs:
CSCsq54877 for the resolver.pl and
CSCsv65933 for the problem that the device name does not get updated in DCR;
you have two options, contact TAC to get the patch or update to LMS 3.2
