3.1.5.1 IVdsService Interface

Servers implement the IVdsService interface in order to support storage management.

The UUID for this interface is {0818A8EF-9BA9-40D8-A6F9-E22833CC771E}.

The IVdsService methods are specified in section 3.4.5.2.4. A method is not listed for opnum 7 because the Virtual Disk Service Remote Protocol does not use it. Attempting to call a method with opnum 7 can result in NDR raising a RPC_X_BAD_STUB_DATA exception. For more information, see [MS-DCOM].

Methods in RPC Opnum Order

Method	Description
IsServiceReady	Determines whether a service is finished initializing. Opnum: 3
WaitForServiceReady	Waits for VDS initialization to complete and then returns the status of the VDS initialization in the HRESULT. Opnum: 4
GetProperties	Retrieves the properties of the service that is represented by the object that exposes this interface and method. Opnum: 5
QueryProviders	Enumerates the providers of the server. Opnum: 6
Opnum07NotUsedOnWire	Reserved for local use. Opnum: 7
QueryUnallocatedDisks	Enumerates the unallocated disks on the server. Opnum: 8
GetObject	Retrieves an IUnknown pointer to a specified object. Opnum: 9
QueryDriveLetters	Enumerates the drive letters of the server. Opnum: 10
QueryFileSystemTypes	Returns property details for all file systems that are known to VDS. Opnum: 11
Reenumerate	Discovers newly added and newly removed disks and returns the status of the operation in the HRESULT. Opnum: 12
Refresh	Refreshes the ownership and layout of disks on the server. Opnum: 13
CleanupObsoleteMountPoints	Removes any mount points that point to volumes that no longer exist. Opnum: 14
Advise	Registers a notification callback with the server. Clients pass the callback object to the server to receive notifications. Opnum: 15
Unadvise	Unregisters a client from notification of changes to storage objects by the server. Opnum: 16
Reboot	Restarts the computer on which the server is running. Opnum: 17
SetFlags	Assigns property flags to the server. Opnum: 18
ClearFlags	Clears property flags from the service. Opnum: 19

All methods MUST NOT throw exceptions.

In the previous table, the term "Reserved for local use" means that the client MUST NOT send the opnum, and the server behavior is undefined because it does not affect interoperability.
