Expand or Scale Out Clusters

Once the cluster is created, you can expand or scale out the cluster by adding more platform nodes to it.
  • Before you scale up the cluster, you must take a backup of the cluster. For more information about the backup and restore process, see the KB article 55829.
  • You must perform the expand cluster operation only from Platform 1 (P1) node.
  1. Go to
    Settings
    Infrastructure and Support
    Infrastructure and Updates
    .
  2. On the
    Infrastructure and Updates
     page, click
    EXPAND CLUSTER
     for
    Platform VMs
    .
  3. The IP addresses of the VMs that are part of the cluster already are listed on the
    Expand Cluster
     page. To add one or more nodes to the existing cluster, provide the IP address (IPv4 or IPv6 address) of the node and the support user password.
    • Currently,
      VMware Aria Operations for Networks
       supports 15 nodes in an existing cluster. Once the limit is reached, the
      Add more
       button is deactivated.
    • Ensure that all the new nodes do not have license keys applied (non-provisioned) and are reachable through SSH.
    • Ensure that you have taken a backup of the existing platform VMs before you go ahead with the cluster expansion.
  4. Click
    SUBMIT
    .
    The step-by-step progress is displayed.
  5. Once the cluster expansion link is completed, a message indicating success is displayed.
    While the cluster expansion is in progress, the application cannot be used for any other operation.
If you are on the Deployment Scenario 2, then you must reconfigure your platform. To reconfigure, on the
Infrastructure and Updates
page, under in
Platform Capacity
 section, click the
RECONFIGURE
 button.
The
RECONFIGURE
 button appears only when your platform needs reconfiguration.
To know about the deployment options and the other system requirements, see System Recommendations and Requirements.
