This part of the lab is presented as a Hands-on Labs Interactive Simulation. This will allow you to experience steps which are too time-consuming or resource intensive to do live in the lab environment. In this simulation, you can use the software interface as if you are interacting with a live environment.

The orange boxes show where to click, and the left and right arrow keys can also be used to move through the simulation in either direction.

vCloud Availability not only allows users to failover their on-prem production workloads to a VMware Cloud Partner, but it also allows the users to migrate (or failback) those workloads back into their datacenter as well.

The first step that needs to happed to allow failback is to reverse the direction of the replicaiton. When a failover is run, replication stops. When it's time to start planning failback to the original location, we need to configure replication in the reverse direction of the original (replicate the workload running in the cloud back to a target in the on-prem vCenter).

1. In the vCloud Availability interface, click the Reverse button in the Actions section.
2. Click the scroll bar to scroll down.
3. Click the Confirm button. Notice that the workload disapears.
4. Click the Home tab. Note that is shows 1 reversed workload.
5. Click the Workspaces tab. Note that it now shows 1 Reversed workload.
6. Click the Reversed tab. Notice that the CentOS VM now shows up under Reversed.
7. Click the CentOS VM. Note the Actions section shows its doing the initial full sync.

1. Click on the vCloud Director tab in the browser.
2. Click the Refresh icon to make sure the VM is still running.

1. Click on the vSphere Web Client tab in the browser.
2. Click the Incoming Replications link to see the new replication.
3. Click the Refresh icon to check the progress. It's at 93%.
4. Click the Refresh icon again. It's finished!

Go back to the vCloud Availability interface to initiate the Failback.

1. Click the vCloud Availability tab in the browser.
2. Click the Home tab to see that status. The workload is still reversed.
3. Click the Workspaces tab.
4. Click the Reversed link.
5. Click the CentOS VM.
6. Click the Failback button in the Actions section to initiate a failback.
7. Click the scrollbar to scroll down.
8. Click the Start button.

1. Click the vSphere Web Client tab in the browser.
2. Click the Refresh icon to see the new status (Recovered).
3. Click the CentOS VM.

See that it is booting up. We have successfully migrated it back from vCloud Director to vSphere.
