No cmdlet for that afaik, but you could use the CheckRelocate method.
The snippet is for 1 VM, but you can easily adapt this to loop through a number of VMs.

$si = Get-View ServiceInstance
$relCheck = Get-View -Id $si.Content.VmProvisioningChecker

$spec = New-Object -TypeName VMware.Vim.VirtualMachineRelocateSpec
$spec.Datastore = $null
$testType = 'datastoreTests'

$vmName = '<MyVM>'
$vm = Get-VM -Name $vmName

Get-VMHost -VM $vm | Get-Datastore -PipelineVariable ds |
ForEach-Object -Process {
  $spec.Datastore = $ds.ExtensionData.MoRef
  $relCheck.CheckRelocate($vm.ExtensionData.MoRef,$spec,$testType) |
  Select @{N='Datastore';E={$ds.Name}},
    @{N='VM';E={$vm.Name}},
    @{N='Warning';E={$_.Warning.LocalizedMessage}},
    @{N='Error';E={$_.Error.LocalizedMessage}}
}

$testType = 'datastoreTests'

You shouldn't change that, that is the test you want to do.

Tested again, works for me.
