In our previous posts we have seen on what is vCenter HA & How to setup vCenter HA. vCenter HA also called as VCHA. vCenter HA provides the High Availability for the vCenter Server so that if your vCenter Server instance goes down you still have the copy of your vCenter Server which can be easily used for all the operations. vCenter High Availability only works with the vCenter Server Appliance. For using the vCenter High Availability you should be running vSphere 6.5.
Once the VCHA is configured successfully you can do failover test to check the working of vCenter High Availability & you can also be assure that the secondary vCenter Server is working properly. In this post we will see on How to do test the failover in VCHA. Once the primary vCenter Server is down it takes around 5-10 minutes or less depending on your environment to come the secondary vCenter Server online.
Let’s see step by step :
Login to vSphere web client.
Select the vCenter Server.
Go to Config Tab & choose vCenter HA.
Here you can see all the details about your vCenter HA such as health status, IP Address etc.
For doing the failover click on button Initiate Failover.
You will get prompt for initiate HA Failover.
Click Yes to Initiate.
Once the failover process starts vSphere web client will be unavailable for access.
You can try to refresh the browser window till the time.
You will see the page as Failover in progress.
It will take around 5-10 minutes or less to come the passive vCenter Server to become Active.
As you can see in the below image that we have done the successful failover test & now Passive vCenter Server is running as the primary vCenter Server.
If you want to go to your primary vCenter to be running then you can follow same process again.
That’s it this is how you can do the vCenter HA failover test in your environment.
If you have not configured the vCenter HA then check below links for more:
