        Initial configuration wizard displays a license error after successfully configuring the cluster

Initial configuration wizard displays a driver node not selected error

You select the cluster nodes on the Select Nodes panel of the cluster configuration wizard. While choosing the nodes if the driver node is not part of the selected nodes, the wizard does not allow you to proceed.

You may see the following error: 

Driver node must be selected for configuring the cluster.

Note:

For version 3.1, the driver node is selected by default and you can't clear this selection.

Cause

The node from where you launch the NetBackup Flex Scale cluster configuration wizard workflow is referred to as the driver node. During cluster configuration, the driver node must be included in the list of the nodes that are selected to be a part of the NetBackup Flex Scale cluster. This node is critical because the cluster configuration processes are triggered from the node.

Solution

Ensure that the driver node is included in the selected nodes. In case the number of cluster nodes is higher, for example, 8 nodes or more, you can perform the following steps to easily identify the driver node:

  1. On the Select Nodes panel, click Export inventory CSV to download the nodes inventory file.

  2. Open the .csv file in a text editor and observe the contents.

    The csv file contains a comma separated list of all the available nodes along with other parameters such as the node name, the management IP addresses assigned, the data and management network adapter MAC addresses and so on.

    You may see the following types of entries in the file:

    Model,Product version,Management IP,eth1 mac address,Host name,Serial number,eth5 mac address
5551,1.3,10.xx.xxx.15,00:50:56:b5:c0:8f,lam-01.mydomain.com,virtual-42357921c,00:50:56:b5:96:3a
5551,1.3,,00:50:56:b5:db:81,lam-02.mydomain.com,virtual-423555166e0a8f2e-b217,00:50:56:b5:cf:87

  3. Identify the node that has the management IP assigned. This is the driver node from where you launched the cluster configuration wizard. Make a note of the node name or the MAC address of the data network adapter or the management network adapter.

    Note:

    The management IP is the IP address that you used to connect to the node and launch the cluster configuration wizard.

  4. Go back to the cluster configuration wizard and from the nodes list displayed in the Select Nodes panel find the node that matches the details you noted earlier and then select that node.

  5. Click Save to update the inventory and continue with the cluster configuration process.
