9 Change the host name and IP address on the first VM (VM1).
Note the original IP address and host name that were used at the time of the installation of
vCenter Server on VM1. This information is used to assign a cluster role IP.
10 Install failover clustering on both nodes.
11 To create an MSCS cluster on VM1, include both nodes in the cluster. Also select the validation
option for the new cluster.
12 To start configuring roles, select Generic Service and click Next.
13 Select VMware Service Lifecycle Manager from the listed services and click Next.
14 Enter the host name and IP used for the VM1. Then assign the RDM to the role.
15 In the Replicate Registry Settings wizard, add the registry key
SYSTEM\CurrentControlSet\Services\VMwareDirectoryService and click Next.
16 Using Add Resource, add the VMware AFD and VMware vCenter Configuration services to the role.
17 Stop and restart the role.
You have created an MSCS cluster that can support vCenter Server availability.
What to do next
After you have created the MSCS cluster, verify that failover is occurring by powering off the VM hosting
vCenter Server (VM1).In a few minutes, verify that the services are running on the other VM (VM2).
