3.3.2 TimersNone.3.3.3 InitializationA client initializes by creating an RPC binding handle to the IVdsServiceLoader interface. For moreinformation on how to get a client-side RPC binding handle for an IVdsServiceLoader interface,see [MS-DCOM] section 3.2.4.After the client obtains the IVdsServiceLoader interface, the client MUST invokeIVdsServiceLoader::LoadService on the interface to retrieve the IVdsService interface.If the IVdsService interface was NOT obtained by calling IVdsServiceLoader::LoadService, theclient MUST invoke IUnknown::QueryInterface to retrieve the IVdsServiceInitialization interface.If the IVdsService interface was obtained by calling CoCreateInstance (see [MSDN-CoCreateInstance]) on the VDS server with the class GUID of the VDS service, then the clientMUST:•Invoke IUnknown::QueryInterface on the interface to retrieve the IVdsServiceInitializationinterface.•After the client obtains the IVdsServiceInitialization interface, the client MUST invoke theIVdsServiceInitialization::Initialize method on the interface before invoking any othermethod.All the clients MUST then do one of the following before invoking any other methods:•Invoke IVdsService::WaitForServiceReady and wait for it to return with a success code.•Invoke IVdsService::IsServiceReady in a loop until this method returns a success code.3.3.4 Message Processing Events and Sequencing Rules3.3.4.1 Processing Server Replies to Method CallsAfter the client receives a reply from the server in response to a method call, the client MUSTvalidate the return code. Return codes from all method calls are HRESULTs. If the HRESULTindicates success, the client can assume that any output parameters are present and valid.Certain calls must be performed in sequence. For example, where method A is a prerequisite call formethod B, the client will pass output parameters from method A as input parameters to method B,as described in section 3.2.1.1.1. If method B is called, then the client must retain A's outputparameters until B completes.The client MUST release any DCOM interfaces that the server returns when the client no longerneeds them.3.3.4.2 Processing Notifications Sent from the Server to the ClientThe client SHOULD choose to implement the IVdsAdviseSink interface in order to receivenotification from the server of changes to the storage objects on the server. Notifications are sent tothe client for creating, deleting, and modifying storage objects. The client can choose to take otheraction based on these notifications. The client can also choose to ignore notifications from theserver.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011152 / 360
Notifications that are related to storage object modification indicate a state change, such as when adisk status changes from VDS_DS_ONLINE to VDS_DS_FAILED, or when a volume length changesbecause of a call to IVdsVolume::Extend.3.3.4.3 IVdsAdviseSink Methods3.3.4.3.1 IVdsAdviseSink::OnNotify (Opnum 3)The OnNotify method passes notifications from VDS to applications.HRESULT OnNotify([in, range(1,100)] long lNumberOfNotifications,[in, size_is(lNumberOfNotifications)]VDS_NOTIFICATION* pNotificationArray);lNumberOfNotifications: The number of notifications that are specified in pNotificationArray.This parameter MUST be a value from 1 through 100.pNotificationArray: An array of VDS_NOTIFICATION structures.Return Values: The method MUST return zero or a non-error HRESULT (as specified in [MS-ERREF]) to indicate success or return an implementation-specific nonzero error code toindicate failure. For the HRESULT values predefined by the Virtual Disk Service RemoteProtocol, see section 2.2.3.3.3.5 Timer EventsNone.3.3.6 Other Local EventsNone.3.4 Server DetailsUnless otherwise specified, all methods MUST return zero or a non-error HRESULT (as specified in[MS-ERREF]) to indicate success, or return an implementation-specific nonzero error code toindicate failure. For the HRESULT values predefined by the Virtual Disk Service Remote Protocol, seesection 2.2.3.3.4.1 Abstract Data ModelThe server maintains the following information to use in responding to client queries and commands.Unless otherwise specified, zero indicates success.This section describes a conceptual model of possible data organization that an implementationmaintains to participate in this protocol. The described organization is provided to facilitate theexplanation of how the protocol behaves. This document does not mandate that implementationsadhere to this model as long as their external behavior is consistent with that described in thisdocument.[MS-VDS] — v20110610Virtual Disk Service (VDS) Protocol SpecificationCopyright © 2011 Microsoft Corporation.Release: Friday, June 10, 2011153 / 360
