16.6 Deactivating the IPv6 management feature

You can administratively disable the IPv6 capabilities using either of the following methods:

  1. Turn off the IPv6 master switch in the nms-jboss.properties file, then restart NNMi.

  2. Let the NNMi Advanced license expire, or replace it with a basic NNMi license.

To administratively disable the IPv6 feature by using method 1:

  1. Open the nms-jboss.properties file.

    Locate the following line:

    • Windows: %NNM_PROPS%\nms-jboss.properties

    • Linux: $NNM_PROPS/nms-jboss.properties

    NNMi provides a complete description of each property, showing them as comments in the nms-jboss.properties file.

  2. To deactivate IPv6 communication in NNMi:

    a. Locate the text that begins with # Enable Java IPv6 Communication.

    b. Locate the following line:

     java.net.preferIPv4Stack=false

    c. Edit the line to read as follows:

     java.net.preferIPv4Stack=true

    Make sure the line is not commented.

  3. To deactivate overall IPv6 management in NNMi:

    a. Locate the text that begins with # Enable NNMi IPv6 Management.

    b. Locate the following line:

     com.hp.nnm.enableIPv6Mgmt=true

    c. Edit the line to read as follows:

     com.hp.nnm.enableIPv6Mgmt=false

    Make sure the line is not commented.

    d. Save and close the nms-jboss.properties file.

  4. Execute the following commands to restart NNMi:

    ovstop
    ovstart
    Important

    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. For 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. Check the NNMi processes by using the following command:

     ovstatus -v ovjboss

The following subsections describe NNMi behavior and inventory cleanup after you disable IPv6.
