Powering on VMs with specific notes

[Evilence]

Greetings,

I am trying to create powerCLI script, that powers on virtual machines with specific notes.

For example, after disaster or maintenance, only VM that has "HA" should be powered. Is it possible to implement this via powerCLI?

Try this

Get-VM | where {$_.Notes -match "HA"} | Start-VM -Confirm:$false

Thank you,

That works just great, but unfortunately only for one WM. After that, script hangs

I am trying to perform following:

$vms = get-vm -Location (get-cluster $clustername)

To get all VMs in cluster,

and then

ForEach ($vm in $vms)

{

$vm | where {$_.Notes -match "HA"} | Start-VM -RunAsync

}

But still, only one WM powers on. How can I perform this check on every machine in the cluster?

Sorry for such newbie question

I suspect the Start-VM doesn't hang but that the cmdlet waits for the VM to be started, the Start-VM cmdlet runs by default in sync mode. In other words, it waits till the guest is started.

If you prefer not to wait you can do

Get-VM | where {$_.Note -match "HA"} | Start-VM -Confirm:$false -RunAsync

But beware that this will create a startup storm of VMs which can put a heavy load on your ESX(i) servers.

You can combine all this as follows

Get-Cluster $clustername | Get-VM | where {$_.Note -match "HA"} | Start-VM -Confirm:$false -RunAsync

Thank you for such quick response and help.

It works like a charm
