Configure the vCenter Server Master Server

Consider the following points when configuring your vCenter Server environment:

• Each VMware ESX server locally stores the IP address of the vCenter Server managing it. This address must be changed to the standby server in the event of a switchover. We recommend using the vCenter Server Managed IP Address setting to automate switchover.
• Each VMware ESX server can be managed by only one vCenter Server. Connecting an ESX server to more than one vCenter Server automatically disconnects it from its original server.

When you configure Arcserve RHA on the vCenter Server Master Server, enter the same IP address you entered in the Managed IP Address field as the IP Mask field on the High Availability Properties screen.

If you do not use the Managed IP Address setting, you must manually reconnect all ESX servers to the standby vCenter Server after switchover.

To configure the vCenter Server Master server

1. Add another IP address to the Master server network interface card (NIC). For more information, refer to the topic, Add IP on the Master Server.
2. From the vCenter Server Runtime Settings screen, set the Managed IP address field to the same IP address you added in Step 1, not the Master server's IP address. For more information, refer to the VMware vCenter Server documentation.
3. Run the HostReconnect script to reconnect all ESX servers managed by the vCenter Server. Download this script from the VMware website.

Important! When you create HA scenarios, we recommend that you enable the Move IP redirection method on the Switchover Properties screen. If you enter additional IP addresses to the Master Server NIC, Move IP is enabled by default.
