Zerto Virtual Protection Group (VPG) Test Failover

This is Blog 4 of 5 on Zerto Replication.  This blog will cover how to do a “Test Failover” for a Virtual Protection Group (VPG).  This is a great feature where you can test your DR site at any time without causing any interruption in your production environment. First, let’s recap where we are.

  • We have installed ZVM at both sites
  • The sites have been paired
  • VRAs deployed at both sites
  • VPGs have been configured and replicating

So now we are ready to “Test Failover” the VPG.

1. Go to the VPG you want to failover.  In the bottom right-hand corner make sure the “Test” feature is selected and not the “Live”.  Then select the “Failover” arrow.

2. Make sure the VPG you are testing is checked and hit next

3. The “Configure” option is where you select the bookmarks or point in time you want to use. Select the checkpoint option.

4. Here you select you Recovery Point options.  I will pick the Manual Select Option.

5. Then you can select the Point-in-Time based on your journal settings you chose earlier in the setup

6. Now you are ready to test the failover by clicking the failover arrow

 7. Go back to the VPG and once Zerto and VMware have completed the failover you will be presented with this screen.  You will see in the upper right-hand corner that the VPG is in Test mode as well as the green check at the bottom-left of the screen beside “fail over test”.  Now you can test your VMs on the “Test” network you defined earlier.  During “Test mode” you can initiate a true failover if something happens during that time.

8. After you have completed you’re testing its time to stop the failover test by selecting the “Stop” symbol in the upper right-hand corner.

9. The Stop Failover Test screen will pop-up.  Select the VPG and select the “Stop Selected” option.

10. Once Zerto and VMware have taken down the test VMs and a green check will show up beside “Stop Failover Test”.  Now your VPG is back to normal.

This concludes this blog on failover testing for a VPG.  My final blog in this series will go over an actual failover.
