When your vRealize Operations analytics cluster needs more resources, you can add additional nodes.

You can use this procedure to expand the size of the vRealize Operations analytics cluster one node at a time. The original sizing configuration of your vRealize Operations deployment determines the total number of nodes that you can add. See the vRealize Sizing Tool.

Prerequisites

  • Forward and reverse DNS resolution is working for the FQDN of the new node.
  • The IP address for the new node is in the same subnet as the existing vRealize Operations nodes.
  • The datastore has enough disk space for the new node.

Procedure

  1. On the SDDC Manager Dashboard, click Administration > vRealize Suite.
  2. Click vRealize Operations.
  3. Click Expand.
  4. Enter information for the new node and click Next.
    • Select Data Node for the component type.
    • Enter the FQDN for the new node.
    • By default, the new node uses the password of the primary node. If you want to use a different password for the new node, deselect the check box and enter a new password.
  5. Click Finish.
    Cloud Foundation validates the information and deploys the new node. If there are validation errors, fix the issues and click Finish to try again.
  6. Monitor the deployment in the Tasks pane.
    If the task fails, you can click Restart Task to try again, or click Rollback from Administration > vRealize Suite > vRealize Operations to return to a known good state. You can always restart a failed task. Depending on when a failure occurs, you may or may not be able to roll back the expansion. For rollback troubleshooting, see KB 70991 and KB 70992.
