The Passive and Witness nodes are created. When vCenter HA conguration is complete,
vCenter Server Appliance has high availability protection.
What to do next
See “Manage the vCenter HA Conguration,” on page 68 for a list of cluster management tasks.
Configure vCenter HA With the Advanced Option
If you congure the vCenter HA cluster with the Advanced option, you have more control over the
environment, and you do not have to meet some of the prerequisites for the Basic conguration. However,
you are responsible adding a second NIC to the vCenter Server Appliance, cloning the Active node to the
Passive and Witness nodes, and conguring the clones.
Procedure
1 Create and Congure a Second NIC on the vCenter Server Appliance on page 65
Before you can start the Advanced conguration, you have to create and congure a second NIC on
the vCenter Server Appliance that will become the active node. This NIC will be used for vCenter HA
trac. You perform this task after you set up the network, but before you start the conguration
process.
2 Start the Advanced Conguration Process on page 66
After you congure the network and you add a second NIC to the vCenter Server Appliance, you can
start the vCenter HA conguration process.
3 Create and Congure the Clones of the Active Node on page 66
As part of the Advanced conguration, you have to clone the Active node to create the Passive and
Witness nodes. Do not exit the Congure vCenter HA wizard while you perform the cloning tasks.
4 Complete the vCenter HA Advanced Conguration on page 67
After you create the Passive and Witness nodes, return to the conguration wizard on the Active node
to complete the conguration.
Create and Configure a Second NIC on the vCenter Server Appliance
Before you can start the Advanced conguration, you have to create and congure a second NIC on the
vCenter Server Appliance that will become the active node. This NIC will be used for vCenter HA trac.
You perform this task after you set up the network, but before you start the conguration process.
Prerequisites
n
Set up the infrastructure for the vCenter HA network. See “Congure the Network,” on page 63.
n
Deploy vCenter Server Appliance that you want to use as initial Active node.
n
The vCenter Server Appliance must have a static IP address mapped to an FQDN.
n
SSH must be enabled on the vCenter Server Appliance.
Procedure
1 Log in to the management vCenter Server with the vSphere Web Client.
2 Select the vCenter Server Appliance virtual machine (Active node), add a second network adapter, and
aach it to the vCenter HA portgroup that you created.
