Prerequisites
n
Set up the infrastructure for the vCenter HA network. See Configure the Network.
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 attach it to the vCenter HA portgroup that you created.
3 Log in to the vCenter Server Appliance that will initially become the Active node, directly.
Interface Action
vCenter Server Appliance Go to https://appliance-IP-address-or-FQDN:5480
vSphere Web Client a Go to https://appliance-IP-address-or-FQDN/vsphere-client
b Select Administration > System Configuration
4 Configure the IP settings for the second network adapter.
Start the Advanced Configuration Process
After you configure the network and you add a second NIC to the vCenter Server Appliance, you can start
the vCenter HA configuration process.
Prerequisites
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.
n
Configure the network. See Configure the Network.
n
Determine which static IP addresses to use for the two vCenter Server Appliance nodes that will
become the Passive node and Witness node.
Procedure
1 Log in to the Active node with the vSphere Web Client.
2 Right-click the vCenter Server object in the inventory and select vCenter HA Settings.
3 Click Configure.
4 Select the Advanced configuration option and click Next.
