In vCloud Director, navigate to More in the top bar, then Availability.
In the left pane, choose a replication direction. If you are in your Primary site, your Replications will be Outgoing (to the Secondary site). If you are in your Secondary site, your Replications will be Incoming.
Select the protected vApp or virtual machine to test the failover and click either Test, or All Actions > Test.
In the Test Failover wizard, configure the selected workload for the failover test. On the Recovery Settings page, configure the recovered workload and click Next. The default settings will power on the recovered vApps and apply their current network settings. The VMs can also be connected directly to a different network at the secondary site.
On the Recovery Instance page, configure the recovery point in time and click Next.
On the Ready To Complete page, review the test details and click Finish.
Cloud Director will prompt you for your credentials at the opposing site. Enter your user name (username@org) and password in the format shown below.
In the Last changed column, you can monitor the progress of the test.
After the test finishes, for the vApp and its virtual machines in the Recovery state column you see a Test image ready state.
You now have the option of testing network access, application availability, and other success criteria at the secondary site. To delete the test failover results once the test is complete, select the replication to clean, then click All actions > Test Cleanup.
