Chapter 1 Getting Started with vCenter Server Heartbeat

VMware does not recommend attempting to test a failover in a production environment on a operating server

pair using methods such as unplugging a power cord. When power is lost, any data not written to the passive

server can be lost. VMware recommends performing a switchover rather than a failover to test the operation

of the passive server.

Table 1-2. Acceptance Verification

Exercise Machine Activity Result

Failover Simulation

Exercise

This exercise demonstrates that the Secondary server can function as the Primary Server

without the test data being immediately replicated back to the original server. During the

exercise, you will stop the Primary server from providing service and hide it from the

network, then introduce the Secondary server to the network and allow it to provide service.

Using the System Tray icon, verify that the Primary server displays P/A indicating that it is

the active server. On the Secondary server, repeat the process and verify that the Secondary

server displays S/— indicating that it is passive.

Using the vCenter Server Heartbeat Console, navigate to the Data: Replication tab. Verify

that both the File System and the Registry Status display as Synchronized.

Notify any local users that the service will be unavailable for the duration of the exercise.

Primary Right-click on the System Tray icon and select

Shutdown VMware vCenter Server

Heartbeat. Select the option to Stop all

protected applications.

vCenter Server Heartbeat stops all

monitored services and exits. This can be

verified by navigating to the Service

Control Manager and viewing the status of

the protected services.

Primary Right-click on the System Tray icon and select

Shutdown VMware vCenter Server

Heartbeat. Select the option to Stop all

protected applications.

Primary server becomes passive.

Primary Right-click on the System Tray icon and select

Start VMware vCenter Server Heartbeat. Once

vCenter Server Heartbeat has started,

right-click on the System Tray icon and select

Shutdown VMware vCenter Server

Heartbeat. Select the option to Stop all

protected applications.

This activates the network packet filter

hiding the Primary server from the

network. This can be verified by

navigating to the Service Control Manager

and viewing the status of the protected

services.

Secondary Navigate to Start > All Programs > VMware >

VMware vCenter Server Heartbeat >

Configure Server to launch the Configure

Server wizard. Select the Machine tab and in

the Active Server pane, select Secondary server

to make the Secondary server’s role active.

Right-click on the System Tray icon and select

Start VMware vCenter Server Heartbeat.

The Secondary server starts as the active

server. The System Tray icon displays as

S/A.

Client Compare the application functional status to

the predefined criteria for availability and

performance.

Secondary server behaves as the Primary

server.

Data Replication

Exercise

The Data Replication exercise follows the Failover Simulation exercise performed previously.

The objective is to take a working active server (the Secondary server) and synchronize it with

the passive (Primary server). This exercise also demonstrates that all the correct services

stopped when the Primary server became passive.

vCenter Server Heartbeat is running on the Secondary active server. Using the System Tray

icon, verify that the server status displays S/A. vCenter Server Heartbeat is not running on

the Primary server which is set to passive. Using the System Tray icon, verify that the server

status displays —/

— to indicate that vCenter Server Heartbeat is not running.

Notify any local users that the service will be unavailable for the duration of the exercise.

Primary Right-click on the System Tray icon and select

Start VMware vCenter Server Heartbeat.

vCenter Server Heartbeat starts. Launch

the vCenter Server Heartbeat Console.

Select the Server: Summary tab to show

the connection from the Secondary (active)

to Primary (passive).
