NNM9.20 Application Failover

Hi,

 

  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.

Please use plain text.

Re: NNM9.20 Application Failover

Verify that localhost is configured to map to 127.0.0.1 in the /etc/hosts on both systems, this may help.

Note that vSpehre 4 has not been tested with NNMi, also because vSphere is the set of services wrapped around ESX that delivers vMotion, virtualized storage, virtualize networks etc. look at http://support.openview.hp.com/selfsolve/document/KM00452424 and http://support.openview.hp.com/selfsolve/document/KM836136 This maybe and issue.


Hope this helps.
