Shutting down an AHV node in a Cluster

Before you begin

Shut down guest VMs that are running on the node, or move them to other nodes in the cluster.

Caution: You can only shut down one node for each cluster. If the cluster would have more than one node shut down, shut down the entire cluster.

  1. If the Controller VM is running, shut down the Controller VM.
    1. Log on to the Controller VM with SSH.
    2. Put the node into maintenance mode.
      nutanix@cvm$ acli host.enter_maintenance_mode host_ID [wait="{ true | false }" ]

      Replace host_ID with the host ID of the host.

      Specify wait=true to wait for the host evacuation attempt to finish.

    3. Shut down the Controller VM.
      nutanix@cvm$ cvm_shutdown -P now
  2. Log on to the Acropolis host with SSH.
  3. Shut down the host.
    root@ahv# shutdown -h now
