Activate a compute node

Before being activated, ESX clusters imported from vCenter Server and KVM compute nodes appear on the Compute Nodes overview screen with a status of Unknown. Use the Activate action to add ESX clusters and KVM compute nodes into the cloud. If the cluster or compute node does not appear on the overview screen, see Adding compute nodes to the cloud.

Prerequisites

Minimum required privileges: Infrastructure administrator
For ESX clusters:
- ESX hypervisor hosts are created and configured in a cluster in vCenter Server. For more information, see VMware vSphere Documentation at VMware.
- vCenter Server is registered on the Integrated Tools screen. See Register VMware vCenter Server.
For KVM compute nodes:
- Software, storage, and networking are installed and configured on the compute node hypervisor. See the HP CloudSystem 8.0 Administrator Guide at Enterprise Information Library.
- Space is allocated on the physical server where the hypervisor is running for the log files captured in the /var/log/nova directory.


	NOTE: If you plan to activate an ESX cluster or KVM compute node that is already hosting instances managed by other tools, you must first manually remove these instances using the same tools that you use to manage the instances. (This action cannot be performed using CloudSystem.) Instances that are not managed by CloudSystem consume resources and may cause oversubscription.

Activating a cluster or compute node

From the main menu, select Compute Nodes.
Select the ESX cluster or KVM compute node you want to activate.
Select Actions→Activate.
- If activating an ESX cluster, then skip to step 4.
- If activating a KVM compute node, first complete the steps below, then continue with step 4.
  - Enter the user name and password for the operating system running on the KVM compute node. These credentials are defined when the KVM compute node hypervisor is provisioned.
  - Enter the Cloud Data Trunk interfaces used to connect network devices to the KVM compute node. If there are multiple interfaces, separate them with commas. For example: eth1, eth2. See Networks in CloudSystem Foundation.
Click Activate.

To exit without activating the ESX cluster or KVM compute node, click Cancel.
Verify that the ESX cluster or KVM compute node appears in a green active state on the Compute Nodes overview screen.

NOTE: Do not activate an ESX cluster in more than one cloud.
