IVdsVolume::AddPlex method (vds.h)

  • Article

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Adds a volume as a plex to the current volume.

Syntax

HRESULT AddPlex(
  [in]  VDS_OBJECT_ID VolumeId,
  [out] IVdsAsync     **ppAsync
);

Parameters

[in] VolumeId

The GUID of the volume to be added as a plex.

[out] ppAsync

The address of an IVdsAsync interface pointer, which VDS initializes on return. Callers must release the interface. Use this pointer to cancel, wait for, or query the status of the operation.

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 plex was added successfully.
VDS_S_GPT_BOOT_MIRRORED_TO_MBR
0x80042469L
 The boot volume on a GPT disk has been mirrored to an MBR disk. The new plex cannot be used to boot the computer.
VDS_E_VOLUME_NOT_ONLINE
0x8004243DL
 The volume is not accessible.
VDS_E_VOLUME_NOT_HEALTHY
0x8004243EL
 The volume is failing or has failed.
VDS_E_VOLUME_SPANS_DISKS
0x8004243FL
 The volume spans multiple disks.
VDS_E_REQUIRES_CONTIGUOUS_DISK_SPACE
0x80042440L
 The volume consists of multiple extents.
VDS_E_INVALID_OPERATION
0x80042415L
 The source volume is smaller than the target volume. If the source volume is larger than the target volume, the target volume remains the same size and the operation succeeds.

Remarks

This operation is not valid for basic volumes, which have exactly one plex.

Use this method to add a volume as a plex to another volume. For example, a caller can create a volume (volume B), specify volume B as a new plex to an existing volume (volume A), then remove volume B. The new plex of Volume A occupies the same disk extents as did volume B.

Note  VDS attempts to use the same extents, but cannot guarantee this behavior.
 
Callers can add a mirrored volume as a new plex to another volume. The resulting volume contains plexes equal in number to the sum of the original volumes.

Implementers must return a pointer to the IVdsAsync interface for this method, regardless of whether the call initiates an asynchronous operation.
