Move 2 VMs at the on 2 or more different Hosts

I found this PowerCli script from LucD. It does work really well. 🙂

However I'm trying to find a way to run only 2 storage vMotions on 2 or more hosts reading a list of VMs for each host.
It does work but only 1 host at the time, no sure how to run to foreach at the same time or it will be an entire new way?

That is what I have so far, I've tried to add some if or else if but always ends up with the same results.
Any help or suggestion will be gladly appreciate. 🙂

Thanks,

$vmhost1 = "hostname1"
$vmhost2 = "hostname2"

$vmlist = Import-CSV c:\Temp\migration\VMs_List-123.csv
$vmlist1 = Import-CSV c:\Temp\migration\VMs_List-123.csv | where {$_.vmhost -eq $vmhost1}
$vmlist2 = Import-CSV c:\Temp\migration\VMs_List-123.csv | where {$_.vmhost -eq $vmhost2}

$maxParallel = 2


foreach ($VM1 in $VMlist1) {

write-host "Currently moving VM" $vm1.name "to the DatastoreCluster " $ds -ForegroundColor Green
Move-VM -VM (Get-VM -Name $vm1.name) -Datastore $ds -RunAsync
do {
sleep 5
}
while((Get-Task -Status Running | where{$_.Name -eq 'ApplyStorageDrsRecommendation_Task'}).Count -ge $maxParallel)

foreach ($VM2 in $VMlist2) {

write-host "Currently moving VM" $vm2.name "to the DatastoreCluster " $ds -ForegroundColor Green
Move-VM -VM (Get-VM -Name $vm2.name) -Datastore $ds -RunAsync
do {
sleep 5
}
while((Get-Task -Status Running | where{$_.Name -eq 'ApplyStorageDrsRecommendation_Task'}).Count -ge $maxParallel)
}

}

Hi Luc,

Not sure why the format changes when I post it.

To make sure I took snippet of the errors.

Thanks!

I ran through the complete script, line by line, and for me, it works without an issue.
Are you by any chance connected to more than 1 VCSA?
How many entries in $global:defaultviservers?

We could check which IDs are actually in the array.
Add an extra Write-Verbose line

  Write-Verbose "EOF: $eof   I: $i   J:$j"
  Write-Verbose "TaskArr Count : $($TaskArr.Count)"
  Write-Verbose "IDs : $($TaskArr.Id -join '|')"      # <-- add line
  
  while ((Get-Task -Id $TaskArr.Id -PipelineVariable $tCompleted |

How many entries in $global:defaultviservers?

It returns only 1 vCenter.

I added the line and snip the results, if I let it run it does shutdown the VMs and transfer it to the datacluster but they don't power on.

I'm not sure what is happening, but it says "Move Task is empty", while the count shows 1.
That is all very strange.

To be honest, I ran out of ideas for now.
I would need to debug the script in the environment to try and discover what the issue is.
In my lab it all works.

Hi Luc,

So I redid the script by simplified it with hardcoded variables.
I also limit the number of VMs to test, also we are on a vSphere version 7.0 does that change anything?

This is what it gave me, always seems to have an issue with this line : while ((Get-Task -Id $TaskArr.Id -PipelineVariable $tCompleted |
Also at the end when it tried to start the VM.

Hello again,

I made a little changes to the script and seems to have less errors, just that the -PipelineVariable not adding.

while ((Get-Task | where{$TaskArr.id} -PipelineVariable $tCompleted |
where{$_.State -eq 'Running' -and $_.Name -eq 'ApplyStorageDrsRecommendation_Task' }).Count -ge $maxParallel) {
Write-Verbose "Still background tasks running - going to sleep"
Start-Sleep 5
}

Write-Verbose "Checking for VMs to start"
Write-Verbose "Task in hash table $($TaskArr.Count)"
Get-Task | where{$TaskArr.id} -PipelineVariable $tCompleted | where{$_.Name -eq 'ApplyStorageDrsRecommendation_Task' -and $_.State -eq 'Success'} |
ForEach-Object -Process {
Write-Verbose "Start VM $($tCompleted.ExtensionData.Info.EntityName)"
Get-VM -Name $tCompleted.ExtensionData.Info.EntityName | Start-VM -Confirm:$false
$TaskArr.Remove($tCompleted)

I'm not sure what this is supposed to do?

Get-Task | where{$TaskArr.id} -PipelineVariable $tCompleted | where{$_.Name -eq 'ApplyStorageDrsRecommendation_Task' -and $_.State -eq 'Success'}

When you run this command what is suppose to return? Me doesn't work at all...

((Get-Task -Id $TaskArr.Id -PipelineVariable $tCompleted |

I was hopping to replace this line with something similar that "may" work for me...

This supposed to get the Task object for all the task that are stored in $TaskArr.
The PipelineVariable makes it easier to refer to the returned objects later on.
But the problem seems to be that $TaskArr.Id contains a $null value, which is something I can't seem to reproduce.

Give this variation, where it does not use the Id parameter on the Get-Task cmdlet, a try.

At least the script is getting further.

Seems it now has an issue with the VM's name in the Task object.
The name of the VM is missing in

VERBOSE: Start VM


Let's first eliminate the PipelineVariable and see if that changes anything.

$vmhost1 = "hostname1"
$vmhost2 = "hostname2"
$maxParallel = 2

[System.Collections.ArrayList]$TaskArr = @()

$groups = Import-Csv -Path 'c:\Temp\migration\VMs_List-123.csv' -UseCulture |
Group-Object -Property vmhost

$i = $j = 0

Hello,

This line return the datastorecluster name instead of the vm name :

Get-VM -Name $_.ExtensionData.Info.EntityName

I did several tests, and the $_.ExtensionData.Info.EntityName always contains the VM's name.
What is the name of that Task?
Check what is in $_.Name

Good day Luc,

Sorry for the delay, I changed my environment to see if things are different but $_.ExtensionData.Info.EntityName is still returning the Datastores Cluster name.

No sure about what you are asking, but $_.Name return nothing.

As soon as the script tried to start a VM it doesn't give any errors but don't continue to migrate the other VMs on list, just empty the tasks and looks for VM to start.

Thank you!

So the objects returned by Get-Task do not have a Name property?

Sorry I'm not sure how to test that?
