Summary :
This document will explain how to clear the DNS cache from NNMi.
There are some behaviors when  the configuration in the Network changed for any reason and the DNS was updated  but  in the NNMi application   is still reporting the the "OLD DNS"" name this propably may happen if NNMi didn't refresh the cache information for the DNS.
Solution

In order to verify this you can run the following command:

 

Windows

 

 Program Files (x86)\HP\HP BTO Software \support\nnmtwiddle.ovpl  invoke com.hp.nms.dnsejb:mbean=DNSSupport getHostName <addr>

 

Unix:

 

 /opt/OV/support/nnmtwiddle.ovpl  invoke com.hp.nms.dnsejb:mbean=DNSSupport getHostName <addr>
