Cluster Operations

You can perform the following operations on a cluster:
  • Create cluster: Create a new cluster in the current zone.
  • Enable: Enable the cluster that you selected.
  • Disable: Disable the cluster that you selected.
    Note:
    • If you disable a cluster, all hosts in the cluster will be disabled as well.
    • After you disable a cluster, you can either manually reenable some hosts in the cluster or add a new host in the current cluster without reenabling the entire cluster.
  • Attach or detach L2 network: Attach an L2 network to the cluster or detach an L2 network from the cluster.
  • Attach or detach primary storage: Attach a primary storage to the cluster or detach a primary storage from the cluster.
    Note: Exercise caution. When you detach a primary storage from a cluster, note that:
    • All VM instances on the primary storage will be stopped.
    • All vRouters or VPC vRouters on the primary storage will be deleted, and the network services of associated VM instances will be abnormal.
    • All volumes on the primary storage will probably be used normally.
  • Delete: Delete the cluster that you selected.
    Note:
    • If you delete a cluster, all hosts in the cluster will be deleted as well.
    • Exercise caution. If your primary storage is LocalStorage, all VM instances and volumes on the hosts will be deleted as well.
