How to Configure FT on VM Step by Step

In the previous posts we have learned about what is Fault Tolerance and How it works. Fault Tolerance works on the Virtual Machine level. Where we configure FT on VM to provide continuous availability for that VM. When we enable FT on VM, FT will make secondary copy of that VM and it will be in continuous sync to provide availability so if Primary VM is down secondary VM will take over it.

If you want to know more about Fault Tolerance then check below link;

VMware Fault Tolerance Overview.

Before configuring FT we first require FT logging to be enabled on the Standard or Distributed Switch so to configure it you can check on below link:

How to Configure FT logging on Standard Switch ?

Before configuring FT make sure to check for the requirements of Fault Tolerance on VMware. If any of the requirements will fail then your FT will not be configured.

So Let’s see How to configure FT on Virtual Machines:

Step 1:
Login to vSphere Web Client.
Select and Right Click on VM on which you want to configure Fault Tolerance.
Select Fault Tolerance > Turn On Fault Tolerance.

Step 2:
FT requires shared datastore so select the datastore which is to be used for secondary VMs data.
Click Next.

Step 3:
Select the Host for Secondary VM. So that host will run FT secondary VM.
Click Next.

Step 4:
Review the configuration and click Finish to configure Fault Tolerance.

Once you click Finish you can see in the Recent Tasks FT Configuration has started:

Once all the FT is configured successfully, You can see details of FT in the Summary section of the Virtual Machine. You can easily identify FT VM by just looking at it, because FT vm has dark color.

So As of Now we have successfully configure Fault Tolerance for the Virtual Machine. Now you can Test the Fault Tolerance and do other FT related tasks such as  Turn Off FT, Suspend FT, Migrate Secondary VM, Test Failover, Test Restart Secondary by right clicking FT VM:

configure ft in vmware

 

Using Test Failover and Test Restart Secondary you can check the working of Fault Tolerance you have configured. It will just take few seconds to test it.

So this is how you can configure Fault Tolerance on your most important virtual machines which requires continuous availability with zero downtime.
