Manually removing a node from the VMware vRealize Operations Manager 6.x cluster (2114077)

  • 5 Ratings

Symptoms

  • A node may be duplicated on the Administration > Cluster Management page.
  • A node is powered off and deleted without removing it from the VMware vRealize Operations Manager cluster. The node is listed as inaccessible.
  • Attempts to gracefully remove the node from either of the scenarios does not succeed.
  • The main vRealize Operations Manager UI may not be accessible.

Resolution

To resolve this issue, use one of these options:
  • Remove the Data or Remote Collector node by running this command as root from any of the nodes in the cluster:

    curl -ik -u 'admin:password' -X DELETE https://master_node_IP/casa/deployment/slice/node_to_remove_IP

    where:
    • password is the admin user password
    • master_node_IP is the IP of the Master node
    • node_to_remove_IP is the IP of the node that you want to remove from the cluster

  • Remove the Master or a Replica node by running this command as root from any of the nodes in the cluster:

    curl -ik -u 'admin:password' -X DELETE https://master_node_IP/casa/deployment/slice/node_to_remove_IP/replacement_node_IP

    where:
    • password is the admin user password
    • master_node_IP is the IP of the Master node
    • node_to_remove_IP is the IP of the node that you want to remove from the cluster
    • replacement_node_IP is the IP of the node that replaces the Master or Replica node that you are removing

    Notes:
    • HA must be enabled for this call to succeed.
    • Large clusters might take additional time to repopulate the data.

Additional Information

It may be necessary to reboot all nodes in the vRealize Operations Manager cluster after making the changes in the configuration files noted in the preceding section.
