Storage: Remove a Block for the Registered Application
If a block is no longer needed, the application should remove it from the NVM.
1. Register the application, as described in the Storage: Register Application, Perform Task, Unregister Application flow. You should have the session handle and application handle available.
2. Retrieve the block handle for the block of interest, as described in the Storage: Get the Block Handles for an Application flow.
3. Invoke AMT_ThirdPartyDataStorageService.DeallocateBlock with the following input parameters:
Parameter | Description/Value |
SessionHandle | The session handle. |
BlockHandle | The handle of the block to be removed. |

$thirdPartyDataStorageServiceRef =$wsmanConnectionObject.NewReference("SELECT * FROM AMT_ThirdPartyDataStorageService WHERE Name='Intel(r) AMT Third Party Data Storage Service'")
$inputObject =$thirdPartyDataStorageServiceRef.CreateMethodInput("DeallocateBlock")
# $sessionHandle is the session handle returned by 'RegisterApplication' method.
$inputObject.SetProperty("SessionHandle",$sessionHandle.ToString())
# $blockHandles contains one or more block handles returned by 'GetAllocatedBlocks' method.
$inputObject.SetProperty("BlockHandle",$blockHandles.Item(0).ToString())
$outputObject =$thirdPartyDataStorageServiceRef.InvokeMethod($inputObject)
$returnValue =$outputObject.GetProperty("ReturnValue")
4. Unregister the application when done. See Storage: Register Application, Perform Task, Unregister Application.
