Chapter 3 Installing vCenter Server Heartbeat on Identical Nodes
19 For a LAN environment, click Add to specify the IP address. Click Next.
If installing in a LAN or when the WAN uses the same subnet, go to Step 23.
20 For a WAN environment, specify IP addresses of the Secondary server and the Primary server.
21 Add each Principal (Public) network address until all addresses are present. Click Next.
22 When the Principal (Public) addresses on the Secondary server are different from those on the Primary
server, vCenter Server Heartbeat must perform additional tasks during failover or switchover. These
additional tasks require clients to change their resolution of the active server to a different IP address and
requires that vCenter Server Heartbeat update the DNS entries for the active server across the enterprise.
Such updates require credentials for domain administrators (or an account with equivalent rights). Type
the Domain Name, a domain administrator Username and Password in the respective text boxes and
click Next.
