Updating AssetTag in Instrumented BIOS

Hi All,

In order to try to change the AssetTag in a Proliant Server I've entered in Powershell:

$a=Get-WmiObject -Class “HP_SMBIOS_ProcessorInformation” –Namespace“root\HP\InstrumentedBIOS”

$a.AssetTag ="123456"

$a.Put()

It's returned the following error:

Exception calling "Put" with "0" argument(s): "Not supported "

At line:3 char:1

+ $a.Put()

+ ~~~~~~~~

+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException

+ FullyQualifiedErrorId : DotNetMethodException

Does this mean that the AssetTag property is not editable?

Thanks in advance!
