Disabling or turning Off VMware FT
Details
You might need to either disable or turn off the VMware Fault Tolerance (FT) feature. For example, if you are downgrading a license, VMware FT might not be supported by the downgraded license. In such a case, you must first disable or turn off VMware FT for all virtual machines on which VMware FT is currently enabled.
Disabling VMware FT preserves the secondary virtual machines, their configuration, and all history. Use this option if you might re-enable VMware FT in the future. Turning off VMware FT deletes all secondary virtual machines, their configuration, and all history. Use this option if you do not plan to re-enable VMware FT.
Solution
To disable VMware FT on a virtual machine:
In the vSphere Client, right-click the virtual machine with Fault Tolerance enabled, click Fault Tolerance, and click Disable Fault Tolerance.
To turn off VMware FT on a virtual machine:
In the vSphere Client, right-click the virtual machine with Fault Tolerance enabled, click Fault Tolerance, and click Turn Off Fault Tolerance.
Note: Disabling or turning off VMware FT can be performed whether the virtual machines are powered on or powered off.
Note: If you are downgrading a license and FT is no longer supported by this license, ensure that Fault Tolerance Logging is disabled on the VMkernel Port. For related information, see:
