AddVirtualDisk method of the MSFT_MaskingSet class

Adds one or more virtual disks to the masking set.

Adding a virtual disk allows the disk to be shown to the initiators contained in the set.


UInt32 AddVirtualDisk(
  [in]  String                  VirtualDiskNames[],
  [in]  UInt16                  DeviceNumbers[],
  [in]  UInt16                  DeviceAccesses[],
  [in]  Boolean                 RunAsJob,
  [out] MSFT_StorageJob REF CreatedStorageJob,
  [out] String                  ExtendedStatus


VirtualDiskNames [in]

Array of strings containing virtual disk names. This parameter is required and cannot be NULL.

DeviceNumbers [in]

Array of device numbers for the virtual disks. This parameter is required.

DeviceAccesses [in]

Array of device accesses for the virtual disks.

Read Write (2)
Read-Only (3)
No Access (4)
RunAsJob [in]

This parameter controls the asynchronous behavior the method will follow.

TRUE to use the CreatedStorageJob out parameter when the request takes a long time to service; otherwise FALSE.

If a storage job has been created to track the operation, this method will return 4096 - 'Method Parameters Checked - Job Started'. Note, even if RunAsJob is TRUE, the method can still return a result if it finishes in sufficient time.

If FALSE or NULL, this method will follow default WMI asynchronous behavior as determined by the client's method for invocation (i.e. synchronous unless requested otherwise).

CreatedStorageJob [out]

If RunAsJob is set to TRUE and this method takes a while to execute, this parameter returns a reference to the storage job used to track the long running operation.

ExtendedStatus [out]

A string that contains an embedded MSFT_StorageExtendedStatus object.

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