Validate storage vmotion compatibility with powerCLI

[TheVMinator]

If I use vSphere Web Client to storage vMotion a VM, it does a compatibility / validation when I select the datastore and tells me whether the storage vmotion will succeed before I try it.  If there are any issues such as the datastore isn't mounted to the ESXi host the VM is on - it will tell me before I attempt the sVmotion and the compatibility check / validation will fail.

What I'd like to do is take a VM I'm about to sVmotion and do a compatibility check before I actually attempt the storage vMotion and see if there are any issues first.

Can this be done in PowerCLI?

Thanks!

No cmdlet for that I'm afraid, but the RecommendDatastores method should be able to provide that information.

OK thanks again. That might actually work. But how would I use it? How would I compare the data store that I want to move my VM to to the list of recommended data stores and see if the data store I want to move it to is in the list?

Try the following method, I think that is more like the Web Client is showing.

$vmName = 'MyVM'

$tgtDSName = 'MyDS'

$vm = Get-VM -Name $vmName

$ds = Get-Datastore -Name $tgtDSName

$si = Get-View ServiceInstance

$vmProvCheck = Get-View -Id $si.Content.VmProvisioningChecker

$spec = New-Object VMware.Vim.VirtualMachineRelocateSpec

$spec.Datastore = $ds.ExtensionData.MoRef

$result = $vmProvCheck.CheckRelocate($vm.ExtensionData.MoRef,$spec,$null)

$result | %{

    $_.Error | Select @{N='Message';E={$_.LocalizedMessage}}

}
