[MS-VDS]: Virtual Disk Service (VDS) Protocol Specification

Virtual Disk Providers and Virtual Disks: Similar to hardware-providers, the client invokesIVdsService::QueryProviders with the flag VDS_QUERY_VIRTUALDISK_PROVIDERS to obtain alist of VDS virtual disk providers, each of which implement an IVdsVdProvider interface. The clientinvokes the IUnknown QueryInterface method to retrieve an IVdsVdProvider interface on thevirtual disk provider object. The client then invokes IVdsVdProvider::QueryVDisks to obtain a listof virtual disks that the provider maintains. The server responds with a IEnumVdsObject interface,which enumerates a list of IUnknown interfaces, one for each virtual disk. The client invokesIUnknown::QueryInterface to retrieve an IVdsVDisk interface on the virtual disk object.Service and Unallocated Disks: The client invokes IVdsService::QueryUnallocatedDisks to obtaina list of disks that do not have a recognized disk partitioning format. The server responds with anIEnumVdsObject interface, which enumerates a list of IUnknown interfaces, one for eachunallocated disk that is available on the server. The client invokes IUnknown::QueryInterface toretrieve an IVdsDisk, IVdsDisk2, IVdsDisk3, IVdsAdvancedDisk, IVdsAdvancedDisk2,IVdsDiskPartitionMF, IVdsDiskPartitionMF2, IVdsCreatePartitionEx, IvdsDiskOnline, orIVdsRemovable interface on the disk object.Service and Disks: The client invokes IUnknown::QueryInterface on the IVdsService interfaceto retrieve the IVdsServiceUninstallDisk interface. The client invokesIVdsServiceUninstallDisk::UninstallDisks to uninstall one or more disks that are installed on theserver. See section 3.2.1.4. The client invokes IUnknown::QueryInterface on the IVdsServiceinterface to retrieve the IVdsServiceSAN interface. The client invokesIVdsServiceSAN::GetSANPolicy to query the current SAN policy setting, andIVdsServiceSAN::SetSANPolicy to set the SAN policy.Service and File System Types: The client invokes IVdsService::QueryFileSystemTypes to obtaina list of the file system types that are available for use in formatting volumes. The server returns alist of VDS_FILE_SYSTEM_TYPE_PROP structures.Service and Drive Letters: The client invokes IVdsService::QueryDriveLetters to obtain a list ofdrive letters on the system. The server returns a list of VDS_DRIVE_LETTER_PROP structures;the bUsed member indicates whether the drive letter is in use.Service and HBA Ports: The client invokes IUnknown::QueryInterface on the IVdsServiceinterface to retrieve the IVdsServiceHba interface. The client invokesIVdsServiceHba::QueryHbaPorts to obtain a list of the HBA ports that are connected to theserver. The server responds with an IEnumVdsObject interface, which enumerates a list ofIUnknown interfaces, one for each HBA port that is connected to the machine. The client invokesIUnknown::QueryInterface to retrieve an IVdsHbaPort interface on the HBA port object.Service and Initiator Adapters: The client invokes IUnknown::QueryInterface on theIVdsService interface to retrieve the IVdsServiceIscsi interface. The client invokesIVdsServiceIscsi::QueryInitiatorAdapters to obtain a list of the iSCSI initiator adapters that areconnected to the server. The server responds with an IEnumVdsObject interface, whichenumerates a list of IUnknown interfaces, one for each initiator adapter that is connected to themachine. The client invokes IUnknown::QueryInterface to retrieve anIVdsIscsiInitiatorAdapter interface on the initiator adapter object.Service and Initiator Portals: The client invokesIVdsIscsiInitiatorAdapter::QueryInitiatorPortals to obtain a list of the iSCSI initiator portalsthat the initiator adapter maintains. The server responds with an IEnumVdsObject interface, whichenumerates a list of IUnknown interfaces, one for each initiator portal. The client invokesIUnknown::QueryInterface to retrieve an IVdsIscsiInitiatorPortal interface on the initiatorportal object.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011144 / 360
