Need to change core per Socket

[DevD]

Does anyone know the powercli to check the vCPU of a VM and change the Core per socket to match the vCPU.

Move to PowerCLI

[LucD]

Yes I do.

Try something like this.
But be aware that this is not foo-proof.
You can't change the CoresPerSocket in all cases to NumCPU.

Get-VM -PipelineVariable vm | where{$_.NumCpu -ne $_.CoresPerSocket} |

Set-VM -CoresPerSocket $vm.NumCpu -Confirm:$false

[DevD]

Getting an error.

>Set-VM -PipelineVariable TEST1 | where{$_.NumCpu -ne $_.CoresPerSocket} |Set-VM -CoresPerSocket $vm.NumCpu -Confirm:$false

Set-VM : Cannot validate argument on parameter 'CoresPerSocket'. The argument is null, empty, or an element of the argument collection contains a null value. Supply a collection that does not contain any null

values and then try the command again.

You changed the name of the PipelineVariable is used.
That's why you get the error.

[DevD]

Ohh i though that's the name of VM for which we want to change the config.

[LucD]

No, if you want to test with a specific VM, you can use the Name parameter.

Get-VM -Name TestVM -PipelineVariable vm | where { $_.NumCpu -ne $_.CoresPerSocket } |

Set-VM -CoresPerSocket $vm.NumCpu -Confirm:$false

[DevD]

Tried this but still getting the error.

Get-VM -Name TEST1 -PipelineVariable vm | where { $_.NumCpu -ne $_.CoresPerSocket } |Set-VM -CoresPerSocket $vm.NumCpu -Confirm:$false

Set-VM : Cannot validate argument on parameter 'CoresPerSocket'. The argument is null, empty, or an element of the argument collection contains a null value. Supply a collection that does not contain any null

values and then try the command again.

Ok, try like this.
Remember, the VM needs to be powered off to change this setting.

Get-VM -Name TestVM | where { $_.NumCpu -ne $_.CoresPerSocket } |

ForEach-Object -Process {

   Set-VM -VM $_ -CoresPerSocket $_.NumCpu -Confirm:$false

}
