Reconfiguring the Network Environment

From the Network Environment list of the Service Web UI, an administrator can edit the network environment information provided during initial system setup. Carefully plan any changes you make in this area, as these parameters provide the connections from your data center to the Private Cloud Appliance and can potentially disrupt system operations.

Editing Routing Information

Caution:

It is not supported to change your routing information for your dynamic or static network topology.

Editing Management Node Information

This section explains how to edit IP and hostname information for your management nodes.

Caution:

Changing management node parameters can cause system disruption.

Using the Service Web UI

  1. In the navigation menu, click Network Environment.

  2. In the Network Environment Information page, click the Management Nodes tab.

    The Management Nodes details appear.

  3. In the top-right corner of the page, click Edit.

  4. Click Next to navigate to the page you want to edit, then update the appropriate fields.

  1. In the navigation menu, click Network Environment.

  2. In the top-right corner of the page, click Edit.

  3. In the wizard, navigate to the Admin Network tab and set Admin Networking to Enable.

  4. Enter all the required parameters in the respective fields on the form.

  5. Click Save Changes.

Scenario 2: Administration Network Enabled

If you already configured a separate Administration Network and need to edit its settings, proceed as follows:

  1. In the navigation menu, click Network Environment.

  2. In the Network Environment Information page, click the Admin Network tab.

    The Admin Network details appear.

  3. In the top-right corner of the page, click Edit.

  4. Click Next to navigate to the page you want to edit, then update the appropriate fields.

  5. Click Save Changes.
