      8.  
        Initial configuration wizard displays a license error after successfully configuring the cluster

If cluster configuration fails (for example because an IP address that was already in use is specified) and you try to reconfigure the cluster, the UI displays an error but the configuration process continues to run

Cause

If the license key was already registered when the cluster configuration failed and you try to reconfigure the cluster, an error registering the license key is reported in the UI but the configuration process continues to run. The error is displayed in the UI because the configuration process tries to install the same license key which was installed previously during the cluster configuration. However, the configuration process is not terminated and continues to run.

Solution

Before you reconfigure the cluster, delete the license key from all the nodes using the following steps:

  1. Log on to each node using the following credentials:

    User: admin

    Password: P@ssw0rd

    The NetBackup Flex Scale Appliance Shell Menu is displayed.

  2. To access the root shell type the support elevate command.

    To access the root shell when lockdown mode is configured,

  3. Run the following command to delete the license key:

    rm /etc/vx/licenses/lic/Access_Perpetual.slf
