CreateSnapshot method of the MSFT_VirtualDisk class

Creates a new virtual disk that is a shadow copy of the existing virtual disk.

Syntax


UInt32 CreateSnapshot(
  [in]   String FriendlyName,
  [in]   String TargetStoragePoolName,
  [in]   Boolean RunAsJob,
  [out]  MSFT_StorageJob REF CreatedStorageJob,
  [out]  String CreatedVirtualDisk,
  [out]  String ExtendedStatus
);

Parameters

FriendlyName [in]

The desired name of the shadow copy virtual disk.

This parameter is required and cannot be NULL.

TargetStoragePoolName [in]

The storage pool that should be used to hold the created snapshot. If this parameter is not set, this method will default to using the same storage pool that contains the source virtual disk.

RunAsJob [in]

If TRUE, this method uses the CreatedStorageJob parameter when the request is taking a long time to service. If a storage job has been created to track the operation, this method will return Method Parameters Checked - Job Started.

Note  Even if RunAsJob is TRUE, this method can still return a result if it has finished in sufficient time.

If FALSE or NULL, this method will follow default WMI asynchronous behavior as determined by the client's method for invocation. In other words, it is synchronous unless requested otherwise.

CreatedStorageJob [out]

If RunAsJob is set to TRUE and this method takes a long time to execute, this parameter receives a reference to the storage job object that is used to track the long-running operation.

CreatedVirtualDisk [out]

If the virtual disk is created successfully, this parameter receives a string that contains an embedded MSFT_VirtualDisk object.

ExtendedStatus [out]

A string that contains an embedded MSFT_StorageExtendedStatus object.

This parameter allows the storage provider to return extended (implementation-specific) error information.
