IVdsPack::AddDisk method (vds.h)

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Adds a disk to an online pack.

Syntax

HRESULT AddDisk(
  [in] VDS_OBJECT_ID       DiskId,
  [in] VDS_PARTITION_STYLE PartitionStyle,
  [in] BOOL                bAsHotSpare
);

Parameters

[in] DiskId

The GUID of the disk.

[in] PartitionStyle

The style can be MBR or GPT. See the VDS_PARTITION_STYLE enumeration.

[in] bAsHotSpare

If true, VDS can use the disk as a hot spare; otherwise, the disk cannot be used for this operation. Only hardware providers support hot sparing.

Return value

This method can return standard HRESULT values, such as E_INVALIDARG or E_OUTOFMEMORY, and VDS-specific return values. It can also return converted system error codes using the HRESULT_FROM_WIN32 macro. Errors can originate from VDS itself or from the underlying VDS provider that is being used. Possible return values include the following.

Return code/value	Description
S_OK	The disk was added successfully.
VDS_E_NOT_AN_UNALLOCATED_DISK 0x80042418L	The disk is raw.
VDS_E_OPERATION_DENIED 0x8004240AL	The disk to be added is being cleaned.
VDS_E_PROVIDER_FAILURE 0x80042442L	There is a provider failure during the operation.
VDS_E_NOT_SUPPORTED 0x80042400L	Adding a second disk to a basic pack is not supported.
VDS_E_PACK_OFFLINE 0x80042444L	The target pack is inaccessible.
VDS_E_OBJECT_NOT_FOUND 0x80042405L	The disk is not found.
VDS_E_DMADMIN_METHOD_CALL_FAILED 0x80042420L	The logical disk manager (LDM) service failed to complete a method.
VDS_E_PROVIDER_CACHE_CORRUPT 0x8004241FL	The dynamic provider cache is corrupt.

Remarks

VDS implements this method.

This method initializes a raw disk (a disk that has no partitioning defined) and adds it to the pack. Before this method is called, the raw disk is owned by the VDS service. After this method returns, the disk is owned by the basic provider.

To undo the effect of this method—that is, to remove the partitioning format and cause the disk to be a raw disk that is owned by the VDS service—use the IVdsAdvancedDisk::Clean method.

You cannot use AddDisk to redefine the partitioning on an existing disk.

If you add a GPT disk to a basic pack, the operation automatically creates a MSR partition on the disk. Devices running the WinPE operating system are the exception because an administrator might prefer to create an ESP partition on the disk. The ESP partition, if present, must be the first partition on the disk.

If you add the disk to a dynamic pack, the operation does not create a MSR partition.
