Run the Setup Wizard to Add a Primary Replica Node

To activate high availability (HA) for a
VMware Aria Operations
 cluster, specify one of the data nodes to become a replica of the primary node.
  • Create and configure the primary node.
  • Create and configure a data node with a static IP address.
  • Note the fully qualified domain name (FQDN) or IP address of the primary node.
If the cluster is running, activating HA restarts the cluster.
You can add HA to the
VMware Aria Operations
 cluster at installation time or after
VMware Aria Operations
 is up and running. Adding HA at installation is less intrusive because the cluster has not yet started. For more information, see the "High Availability Considerations" topic in the
Reference Architecture
 guide and the "High Availability (HA)" topic in the
VMware Aria Operations Best Practices
 guide.
  1. In a Web browser, navigate to the primary node administration interface.
    https://
    primary-node-name-or-ip-address
    /admin
  2. Enter the
    VMware Aria Operations
     administrator user name of
    admin
    .
  3. Enter the
    VMware Aria Operations
     administrator password and click
    Log In
    .
  4. Under High Availability, click
    Activate
    .
  5. Select a data node to serve as the replica for the primary node.
  6. Select the
    Activate High Availability for this cluster
     option, and click
    OK
    .
    If the cluster was online, the administration interface displays progress as
    VMware Aria Operations
     configures, synchronizes, and rebalances the cluster for HA.
  7. If the primary node and replica node go offline, and the primary remains offline for any reason while the replica goes online, the replica node does not take over the primary role, take the entire cluster offline, including data nodes and log in to the replica node command-line console as a root.
  8. Open
    $ALIVE_BASE/persistence/persistence.properties
     in a text editor.
  9. Locate and set the following properties: 
    db.role=PRIMARY
db.driver=/data/vcops/xdb/vcops.bootstrap
  10. Save and close
    persistence.properties
    .
  11. In the administration interface, bring the replica node online, and verify that it becomes the primary node and bring the remaining cluster nodes online.
After creating a primary replica node, you have the following options.
  • New, unstarted clusters:
    • Create and add data nodes.
    • Click
      Start VMware Aria Operations
       to start the cluster, and log in to finish configuring the product.
      The cluster might take from 10 to 30 minutes to start, depending on the size of your cluster and nodes. Do not make changes or perform any actions on cluster nodes while the cluster is starting.
  • Established, running clusters:
    • Create and add data nodes.
  • To deactivate high availability, click
    Deactivate HA
     and follow the steps in the admin UI. The deativation timeline depends on the cluster size and the data retention period. Please wait for the deactivation to complete.
