PowerCLI and vMotion

[jpoling]

I am migrating VMs to new hosts using the move-vm cmdlet.  The one-liner I am using (courtesy of http://www.simple-talk.com/sysadmin/virtualization/10-steps-to-kick-start-your-vmware-automation-wit...) is:

Get-VMHost esx05 | Get-VM | Move-VM -Destination (Get-VMHost esx06)

What I see right now is that the VMs move one at a time.  Is tehre a way to get it to move more than one VM at a time?

Thanks,

Jeff

Yes, use the RunAsync parameter on the Move-VM cmdlet.

Get-VMHost esx05 | Get-VM | Move-VM -Destination (Get-VMHost esx06) -RunAsync

There will still be only a limited number of migrations that runs concurrently, but that is a limitation of your vSphere environment.

Thanks.  I saw that in the get-help for move-vm, but I wasn't exactly sure what it meant.

-runasync didn't exactly accomplish what I was expecting, but I found out it was because of a limitation.  I am moving VMs to a new cluster.  This KB article indicates that a resource pool can only have one vmotion at a time when moving between resource pools:

Hello again. My objective is to use the Move-VM from one datastore to another one at a time. My script is doing the equivalent to -RunAsync.

C:\> $VMsToRelocate = (Get-Content "C:\Users\username\Desktop\O6297-storage_vm\O6297_SVM.csv")

$Datastore = Get-Datastore -Name "st815zz_vcd_ds8"

foreach ($VM in $VMsToRelocate)

{

Write-Host "Relocating VM:" $VM "to" $Datastore

Get-VM -Name $VM | Move-VM -datastore $Datastore > $null

}

Write-Host "Completed!"

My file is a list of VM names:

VM1

VM2

VM3

It works but all at once. I want one at a time. What am I missing?

[LucD]

Do you see the svMotions (Relocate Virtual Machine) running at the same time in the Web Client?have any

Do you have any default parameters set?Check what is in $PSDefaultParameterValues

[vmCalgary]

$PSDefaultParameterValues is empty.

I see them running concurrently in web client.

I thought I remembered a simiar thread, and this is th eone Re: Move VMs serially

There are a couple of possible solutions in that thread

Thanks as always.
