MethodDescriptionOpnum: 3SetImportTargetSets the import targets for the subsystem.Opnum: 43.1.11 Pack Object InterfacesThis section includes interfaces that are used to interact with disk pack objects on the server.3.1.11.1 IVdsPack InterfaceThe IVdsPack interface is implemented by disk pack objects to support management of diskpacks.The UUID for this interface is {3B69D7F5-9D94-4648-91CA-79939BA263BF}.The IVdsPack methods are specified in section 3.4.5.2.18. No method with opnum 10 is listedbecause it is not used by this protocol.Methods in RPC Opnum OrderMethodGetPropertiesGetProviderQueryVolumesQueryDisksCreateVolumeAddDiskMigrateDisksOpnum10NotUsedOnWireRemoveMissingDiskDescriptionRetrieves the properties of the disk pack that is represented by the objectexposing this interface and method.Opnum: 3Retrieves the provider to which the disk pack belongs.Opnum: 4Retrieves the volumes of a disk pack.Opnum: 5Retrieves the disks of a disk pack.Opnum: 6Creates a volume in a disk pack.Opnum: 7Initializes a disk that has no defined partitioning format and adds it to the diskpack.Opnum: 8Migrates a set of disks from one pack to another pack.Opnum: 9Reserved for local use.Opnum: 10Removes the specified missing disk from a disk pack.Opnum: 11130 / 360[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011
MethodRecoverDescriptionRestores a disk pack to a healthy state.Opnum: 12In the preceding table, the phrase "Reserved for local use" means that the client MUST NOT sendthe opnum, and the server behavior is undefined because it does not affect interoperability.All methods MUST NOT throw exceptions.3.1.11.2 IVdsPack2 InterfaceThe IVdsPack2 interface is implemented by disk pack objects to support creating volumes that arealigned to a particular byte-size boundary.The UUID for this interface is {13B50BFF-290A-47DD-8558-B7C58DB1A71A}.The IVdsPack2 methods are specified in section 3.4.5.2.19.Methods in RPC Opnum OrderMethodCreateVolume2DescriptionCreates a volume in a disk pack with an optional alignment parameter.Opnum: 3All methods MUST NOT throw exceptions.3.1.12 Disk Object InterfacesThis section includes interfaces that are used to interact with disk objects on the server.3.1.12.1 IVdsDisk InterfaceThe IVdsDisk interface is implemented by disk objects in order to support disk management.The UUID for this interface is {07E5C822-F00C-47A1-8FCE-B244DA56FD06}.The IVdsDisk methods are specified in section 3.4.5.2.20.Methods in RPC Opnum OrderMethodGetPropertiesGetPackGetIdentificationDataDescriptionRetrieves the properties of the disk that is represented by the object exposingthis interface and method.Opnum: 3Retrieves the disk pack to which the disk belongs.Opnum: 4Retrieves information that uniquely identifies a disk.Opnum: 5131 / 360[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011
