I am working on the NNM9.20 and I have installed two identical NNM application on 2 servers identical (RHEL 5.4). I have configured NNM for application failover, typically I have done all the configuration related to keystore, truststore and cluster.properties file. All are working and both these servers have infact the same CRC value.
But, when i issue a command nnmcluster, then message comes, " Unable to lookup local hostname, cannot use loopback address "
What's an issue here ??
Both these servers are on same VMsphere, both have the hostname and entry is there in hosts file.
