5.3.5 Multihomed NNMi Management Server

When an NNMi management server is configured to have multiple IP addresses, managed nodes always use the IP address configured with the operating system on the NNMi management server. If you want to configure NNMi to use a non-default IP address while communicating and exchanging data with managed nodes, follow the procedure in this section.

1. Log on to the NNMi Management Server.

2. Open the following file with a text editor:

   • Windows: %NnmDataDir%shared\nnm\conf\props\nms-communication.properties

   • Linux: /var/opt/OV/shared/nnm/conf/props/nms-communication.properties

3. To set a non-default IPv6 address, uncomment the com.hp.ov.nms.comm.snmp.sourceAddress.IPv6 property, and then set the property to an IPv6 address of your choice.

4. To set a non-default IPv4 address, uncomment the com.hp.ov.nms.comm.snmp.sourceAddress.IPv4 property, and then set the property to an IPv4 address of your choice.

   Important

   • If NNMi is installed in an HA cluster, you must reconfigure NNMi. The value of the NNM_INTERFACE property in the ov.conf file must match the value specified with the com.hp.ov.nms.comm.snmp.sourceAddress.IPv4 property in the nms-communication.properties file. For the location of the ov.conf file, see 19.9.1  NNMi HA configuration files.

   • If you change a file while the system is operating in High Availability (HA) mode, you must make the change on both nodes in the cluster. When you use NNMi in an HA configuration, if the change requires you to stop and restart the NNMi management server, you must place the nodes in maintenance mode before running the ovstop and ovstart commands. For details, see 19.6.1 Placing NNMi in maintenance mode.

5. Save the changes.

6. Execute the following commands to restart the NNMi services:

   ovstop -c
   ovstart -c
