VMware.Vim.VirtualMachineRelocateSpec clarification

I try to run a script to create scheduled tasks to move VMs from one datastore to a different one.

I use the VMware.Vim.VirtualMachineRelocateSpec object to specify where each VM must be relocated.

I want to change only the deatastore, not the host, but while creating the scheduled tast I cannot specify "Change datastore" because "Change both host and datastore" is selected anyway.

This is a problem if the VM is powered on...

Can anybody please help?

Regards

marius

As per official API documentation@ VMware.Vim.VirtualMachineRelocateSpec ,

We can just specify target datastore, hence any vSphere SDK + PowerCLI also must honor it.

Can you please post your script here?

Per the documentation, you don't have to specify a host when setting up the specification. Thus, leaving the host property unset should work as a valid relocation spec.

In include my script, based on what suggested by LucD while answering to my prevuous post Creating scheduled tasks

#

# Based on da http://www.lucd.info/2009/10/18/scheduled-tasks-methodaction/

#

Add-PSSnapin VMware.VimAutomation.Core

Connect-VIServer <IP Address> -User <username> 

$csvName = "E:\Test.csv"

$tgtDatastore = <target datastore name>

$emailAddr = <my e-mail address>

$startTime = [Datetime]"10/21/2016 20:00" # late in the future, just to see if the script works

$startInterval = 5

$si = get-view ServiceInstance

$scheduledTaskManager = Get-View $si.Content.ScheduledTaskManager

$offset = 0

Import-Csv $csvName | % {

$a = $_.VMname

$a

$vm = Get-View -ViewType VirtualMachine -Filter @{"Name"=$_.VMname}

$spec = New-Object VMware.Vim.ScheduledTaskSpec

$spec.Name = "svMotion " + $_.VMname

$spec.Description = "Migrate " + $_.VMname + " to " + $tgtDatastore

$spec.Enabled = $true

$spec.Notification = $emailAddr

$spec.Scheduler = New-Object VMware.Vim.OnceTaskScheduler

$spec.Scheduler.runat = $startTime.AddMinutes($offset)

$offset += $startInterval

$spec.Action = New-Object VMware.Vim.MethodAction

$spec.Action.Name = "RelocateVM_Task"

$arg1 = New-Object VMware.Vim.MethodActionArgument

$arg1.Value = New-Object

$arg1.Value.datastore = (Get-Datastore $tgtDatastore | Get-View).MoRef

$arg1.Value.pool = $vm.ResourcePool

$arg1.Value.host = $vm.Runtime.Host

$arg1.Value.host

$spec.Action.Argument += $arg1

$arg2 = New-Object VMware.Vim.MethodActionArgument

$arg2.Value = [VMware.Vim.VirtualMachineMovePriority]"defaultPriority"

$spec.Action.Argument += $arg2

$scheduledTaskManager.CreateScheduledTask($vm.MoRef, $spec)

}


The scheduled task creation is fine, but the task is based on changing both host and datastore.

How can I change the settings?

I made some further tests and I discovered that:

  • If I don't specify any host and any pool and the VM is powered on, a task to change the datastore is created
  • If I don't specify any host and any pool and the VM is powered off, a task to change either host and datastore is created

Is there any way to specify that I want only to change the datastore because my VM is powered on?

I made a further test in a lab environment and I noticed that the tasks created with the script work fine, even if they look to be set in the wrong way.

I apologize for dubiting...

Many thanks to LucD.
