No Hardware Changes Includes No Network Changes
Changing the settings of a virtual network card while a VM is running requires that the network
card be unplugged and then plugged back in. As a result, you can't make changes to virtual net-
work cards while vSphere FT is running.
Because snapshots aren't supported with vSphere FT, you can't back up VMs using any
backup methodology that relies on snapshots. This includes any backup solution that
leverages the vSphere Storage API for Data Protection as well as VMware Data Protection.
To back up a vSphere FT- enabled VM with one of these tools, you must i rst disable
vSphere FT. Chapter 3 explains how you can set a scheduled task to perform a “Disable FT”
and “Enable FT” at a set time frame to suit your backup window.
◆
Be sure to keep these operational constraints in mind when deciding where and how to use
vSphere FT in your environment.
Now you're ready to actually enable vSphere FT on a VM. Perform the following steps to
enable vSphere FT:
1.
If the vSphere Web Client is not already running, launch it and connect to a vCenter
Server instance. vSphere FT is available only when using vCenter Server.
2.
Navigate to the Hosts And Clusters or VMs And Templates view. Right-click a running
VM and then select Fault Tolerance
➢
Turn On Fault Tolerance, as shown in Figure 7.28.

You can turn on
vSphere FT from
the context menu
for a VM.
