[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Uninstalls a set of disks.

Syntax

HRESULT UninstallDisks(
  [in]  VDS_OBJECT_ID *pDiskIdArray,
  [in]  ULONG         ulCount,
  [in]  BOOLEAN       bForce,
  [out] BOOLEAN       *pbReboot,
  [out] HRESULT       *pResults
);

Parameters

[in] pDiskIdArray

Address of a buffer containing an array of VDS object IDs, one for each disk to be uninstalled. Each ID in the array must be unique.

[in] ulCount

Number of VDS object IDs in the buffer that the pDiskIdArray parameter points to.

[in] bForce

If TRUE, VDS uninstalls the disks even if the volumes cannot be locked or dismounted.

[out] pbReboot

Address of a BOOLEAN variable that receives TRUE if the user must restart the computer to complete the uninstall process.

[out] pResults

The address of a caller-allocated array of HRESULT values. The number of elements in the array is pointed to by the pDiskIdArray parameter. The first element of this array corresponds to the first element in the pDiskIdArray, and so on. If any of the disks fails to initialize properly, the specific error code for the failure is returned in the corresponding element of this array.

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 0	The disks were successfully uninstalled.
S_FALSE 1	This method returned a warning or error code for one or more disks.
VDS_S_UNABLE_TO_GET_GPT_ATTRIBUTES 0x0004245BL	The disks were successfully uninstalled, but the GUID partition table (GPT) attributes could not be retrieved for one or more disks.
VDS_E_INTERNAL_ERROR 0x80042448L	VDS encountered an internal error. Check the event log for more information.
VDS_E_MISSING_DISK 0x80042454L	One or more disks were missing.
VDS_E_NO_DISK_PATHNAME 0x8004270FL	The path could not be retrieved for one or more disks.
VDS_E_NO_VOLUME_PATHNAME 0x80042711L	The path could not be retrieved for one or more volumes.
VDS_E_OBJECT_DELETED 0x8004240BL	One or more of the specified VDS object IDs correspond to disks that are no longer present.
VDS_E_OBJECT_NOT_FOUND 0x80042405L	One or more of the specified VDS object IDs correspond to disks that do not exist.
VDS_E_PROVIDER_CACHE_OUTOFSYNC 0x80042712L	The provider's cache is not in sync with the driver cache.

Remarks

VDS implements this method.

This method, which is synchronous, first uninstalls the volumes on the specified disks, and then uninstalls the disks. After the disks are uninstalled, the corresponding LUNs can be masked (hidden) or deleted.

This method cleans up the drive letters that were assigned to the volumes on the disks. In addition, it sets the volumes offline to prevent a volume from being remounted after the dismount handle has been closed but before the disk is actually removed.

When removing a dynamic volume that spans more than one disk, you must call this method instead of using device manager functions.

For instructions on how to uninstall a disk on Windows Server 2003 releases where the UninstallDisks method is not supported, see the Remarks section of the IVdsLun::SetMask method.
