  [in]  BSTR    parentPath,
  [out] IVMTask **diskTask
);

Parameters

parentPath [in]: The path to the parent disk image file.
diskTask [out]: Retrieves the task which is used to track the creation of the image.

Return value

This method supports standard return values, as well as the following. For information on Virtual Server specific return values not listed below, see HRESULT Codes Specific to the Virtual Server.

Return code	Description
S_OK	The operation was successful.
E_POINTER	The imagePath, parentPath, or diskTask parameter is NULL.
E_PATH_NOT_FOUND	The system cannot find the path specified by the imagePath or parentPath parameter.
E_INVALID_NAME	The imagePath or parentPath parameter contains an invalid character (one of "*?:<>/\|"").
E_BAD_PATHNAME	Both the imagePath and parentPath parameter specifies an empty or relative path. At least one of the parameters must be an absolute path.
E_BUFFER_OVERFLOW	The path specified by the imagePath or parentPath parameter is too long. The length of the path must be less than 260 characters.
E_ALREADY_EXISTS	The file referenced by the imagePath parameter already exists.
E_DISK_FULL	The dynamically expanding virtual hard disk image needs at least 8 MB free on the host volume.
VM_E_IMAGE_SIZE_TOO_LARGE	The parameter size must be less than 2,088,960 MB. If format is "vmDiskFormat_FAT16", then size must be less than 2000 MB.
VM_E_IMAGE_SIZE_TOO_SMALL	Unformatted and FAT16 formatted virtual hard disk images must be at least 3 MB.FAT32 formatted virtual hard disk images must be at least 514 MB.
VM_E_FILE_TOO_LARGE_FOR_VOLUME	The host volume cannot support a file this size if the dynamically expanding virtual hard disk image expands to its full limit. The maximum file size for a FAT32 volume is 4 GB.
VM_E_APP_SHUTTING_DOWN	The virtual hard disk cannot be created after the application has started shutting down.
DISP_E_EXCEPTION	An unexpected error occurred.

Remarks

Although either imagePath or parentPath can be a relative path, at least one of these must be an absolute path. If one path parameter is a relative path, it is assumed to be relative to the other path parameter.
