3.2.1.4 DisksIVdsAdvancedDisk::GetPartitionProperties: Prior to invoking GetPartitionProperties, theclient invokes IVdsDisk::QueryExtents or IVdsVolumePlex::QueryExtents to retrieve the offsetparameter. The client passes this returned value as the ullOffset input parameter to theGetPartitionProperties method. IVdsDisk::QueryExtents or IVdsVolumePlex::QueryExtentsreturns this value as the VDS_DISK_EXTENT::ullOffset output parameter.IVdsAdvancedDisk::CreatePartition: Prior to invoking CreatePartition, the client invokesIVdsDisk::QueryExtents , IVdsDisk3::QueryFreeExtents, orIVdsVolumePlex::QueryExtents to retrieve the free disk extents. Using the list of free diskextents, the client can calculate an offset and size for the new partition. The client passes thesecalculated values as the ullOffset and ullSize input parameters to the CreatePartition method.IVdsDisk::QueryExtents returns a list of VDS_DISK_EXTENT structures as an output parameter.These structures contain the offset and size of the free extent as VDS_DISK_EXTENT::ullOffsetand VDS_DISK_EXTENT::ullSize. IVdsDisk3::QueryFreeExtents, andIVdsVolumePlex::QueryExtents return a list of VDS_DISK_FREE_EXTENT structures as anoutput parameter. These structures contain the offset and size of the free extent asVDS_DISK_FREE_EXTENT::ullOffset and VDS_DISK_FREE_EXTENT::ullSize.Prior to invoking CreatePartition, the client invokesIVdsAdvancedDisk::GetPartitionProperties to retrieve the partition type (partition style) for thedisk. The client passes this value as the CREATE_PARTITION_PARAMETERS::style inputparameter to the CreatePartition method. IVdsAdvancedDisk::GetPartitionProperties returnsthis value as the VDS_PARTITION_PROP::PartitionStyle structure member.Prior to invoking CreatePartition, the client invokes IVdsPack::AddDisk to set the partitioningformat for the disk if the disk is not initialized.IVdsAdvancedDisk::DeletePartition: Prior to invoking DeletePartition, the client invokesIVdsAdvancedDisk::GetPartitionProperties, IVdsDisk::QueryExtents, orIVdsVolumePlex::QueryExtents to retrieve the offset parameter. The client passes this returnedvalue as the ullOffset input parameter to the DeletePartition method. If an invalid offset is passedto this method, it will fail. IVdsDisk::QueryExtents or IVdsVolumePlex::QueryExtents returnsthis value as the VDS_DISK_EXTENT::ullOffset output parameter.IVdsAdvancedDisk::GetPartitionProperties returns this value as theVDS_PARTITION_PROP::ullOffset output parameter.IVdsAdvancedDisk::ChangeAttributes: ChangeAttributes has the same call sequencedescription as DeletePartition.IVdsAdvancedDisk::AssignDriveLetter: AssignDriveLetter has the same call sequencedescription as DeletePartition.IVdsAdvancedDisk::GetDriveLetter: GetDriveLetter has the same call sequence description asDeletePartition.IVdsAdvancedDisk::FormatPartition: For call sequencing related to the ullOffset inputparameter, see the description for IVdsAdvancedDisk::DeletePartition. For call sequencing, seesections 3.2.1.1.2, 3.4.1.4, 3.4.1.5, and 4.5.IVdsAdvancedDisk2::ChangePartitionType: For call sequencing related to the ullOffset inputparameter, see the description for IVdsAdvancedDisk::FormatPartition.Prior to invoking ChangePartitionType, the client invokesIVdsAdvancedDisk::GetPartitionProperties to retrieve the partition type for the disk. The client[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011148 / 360
passes this value as the CHANGE_PARTITION_TYPE_PARAMETERS::style input parameter tothe ChangePartitionType method. IVdsAdvancedDisk::GetPartitionProperties returns thisvalue as the VDS_PARTITION_PROP::PartitionStyle structure member.IVdsCreatePartitionEx::CreatePartitionEx: IVdsCreatePartitionEx has the same call sequencedescription as IVdsAdvancedDisk::CreatePartition.IVdsServiceUninstallDisk::GetDiskIdFromLunInfo: Prior to invoking GetDiskIdFromLunInfo,the client invokes IVdsDisk::GetIdentificationData to retrieve the logical unit number (LUN)information for the disk. The client passes this returned value as the pLunInfo input parameter tothe GetDiskIdFromLunInfo method. IVdsDisk::GetIdentificationData returns this value as thepLunInfo output parameter.IVdsServiceUninstallDisk::UninstallDisks: Prior to invoking UninstallDisks, the client invokesIVdsDisk::GetProperties or IVdsDisk3::GetProperties2 for each disk in the input array, toretrieve the list of disk IDs. The client passes this returned value as the pDiskIdArray inputparameter to the UninstallDisks method. IVdsDisk::GetProperties andIVdsDisk3::GetProperties2 return this value as the VDS_DISK_PROP::id orVDS_DISK_PROP2::id output parameter.3.2.1.5 VolumesIVdsVolume::Extend: Prior to invoking Extend, the client invokes IVdsDisk::GetProperties orIVdsDisk3::GetProperties2 for each disk in the input array in order to retrieve the list of disk IDs.The client passes this returned value as the pInputDiskArray input parameter to the Extendmethod. IVdsDisk::GetProperties and IVdsDisk3::GetProperties2 return this value as theVDS_DISK_PROP::id or VDS_DISK_PROP2::id output parameter.IVdsVolume::AddPlex: Prior to invoking AddPlex, the client invokesIVdsVolume::GetProperties or IVdsVolume2::GetProperties2 to retrieve the volume ID. Theclient passes this returned value as the VolumeId input parameter to the AddPlex method.IVdsVolume::GetProperties or IVdsVolume2::GetProperties2 returns this value as theVDS_VOLUME_PROP::id or VDS_VOLUME_PROP2::id output parameter. For more information,see section 3.2.1.1.2.IVdsVolume::BreakPlex: Prior to invoking BreakPlex, the client invokesIVdsVolumePlex::GetProperties to retrieve the plex ID. The client passes this returned value asthe plexId input parameter to the BreakPlex method. IVdsVolumePlex::GetProperties returnsthis value as the VDS_VOLUME_PLEX_PROP::id output parameter. For more information, seesection 3.2.1.1.2.IVdsVolume::RemovePlex: RemovePlex has the same call sequence description asIVdsVolume::BreakPlex.IVdsVolumePlex::Repair: Repair has the same call sequence description asIVdsVolume::Extend.3.2.1.6 Virtual DisksIVdsOpenVDisk::Attach: Prior to invoking Attach, the client invokesIVdsVdProvider::QueryVDisks or IVdsVdProvider::CreateVDisk orIVdsVdProvider::AddVDisk to retrieve the virtual disk object. Then the client invokesIVdsVDisk::Open to retrieve the OpenVirtualDisk object.IVdsOpenVDisk::Detach: Prior to invoking Detach, the client invokesIVdsVdProvider::QueryVDisks or IVdsVdProvider::GetVDiskFromDisk to retrieve an interface[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011149 / 360
