  • 1.  FT-enable a VM.

    To enable FT for a VM:

    Get-VM X | Get-View | % { $_.CreateSecondaryVM($null) }

    This will choose a host, if you want to specify a specific host, pass the host's MOR in place of $null.

    To disable, run:

    Get-VM X | Select -First 1 | Get-View | % { $_.TurnOffFaultToleranceForVM() }

    Note that in PowerCLI 4.0 Get-VM will return a fault tolerant VM twice, so we select the first one.

    I am I right in saying there's no method to enable FT logging on a vmkernel port in the SDK.

    I remember asking this before but I can't remember the answer...

    If it is possible - can you point me to the right location in the SDK online?

    Take a look at to configure FT logging for a given set of ESX(i) hosts for a given FT portgroup, I'm sure this can be accomplished in PowerCLI as well since this just uses the vSphere APIs

    Try this.

    # Enable or disable FT logging.
    $esxHost = ""
    $vmKernel = "vmk0" # You can get these out of Get-VMHostNetwork
    $enable = $true
    $hView = Get-VMHost $esxHost | Get-View -Property configManager
    $nicManager = Get-View $hView.configManager.virtualNicManager
    if ($enable -eq $true) {
    	$nicManager.SelectVnicForNicType("faultToleranceLogging", $vmKernel)
    } else {
    	$nicManager.DeselectVnicForNicType("faultToleranceLogging", $vmKernel)
