Create an EVC cluster to help ensure vMotion compatibility between the hosts in the cluster.
When you create an EVC cluster, use one of the following methods:
Create an empty cluster, enable EVC, and move hosts into the cluster.
Enable EVC on an existing cluster.
VMware recommends creating an empty EVC cluster as the simplest way of creating an EVC cluster with minimal disruption to your existing infrastructure.
You must be connected to a vCenter Server system with the vSphere Client.
Before you create an EVC cluster, ensure that the hosts you intend to add to the cluster meet the requirements listed in the vCenter Server and Host Management publication.
- In the vSphere Client, right-click on a data center and click New Cluster.
- Enter a name for the cluster and select cluster features, then click Next.
Cluster features such as vSphere DRS and vSphere HA are fully compatible with EVC. You can enable these features when you create the cluster. For information on specific cluster options, see the vSphere Client online Help.
- Select the CPU vendor and EVC mode appropriate for the hosts you intend to add to the cluster and click Next.
- Select the Swapfile Policy and click Next.
- Review the selected options for the cluster and click Finish to create the cluster.
- Select a host from the inventory to move into the cluster.
- If the host feature set is greater than the EVC mode that you have enabled for the EVC cluster, ensure that the cluster has no powered-on virtual machines.
Power off all the virtual machines on the host.
Migrate the host’s virtual machines to another host using vMotion.
- Move the host into the cluster.
You can power on the virtual machines on the host, or migrate virtual machines into the cluster with vMotion, if the virtual machines meet CPU compatibility requirements for the cluster’s EVC mode. Virtual machines running on hosts with more features than the EVC mode must be powered off before migration into the cluster.
- Repeat 7 and 8 for each additional host that you want to move into the cluster.
