IVdsIscsiPortalGroup::AddPortal method (vds.h)
[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]
Adds a portal to a portal group. A portal can belong only to a single portal group within a particular target. It can belong to other portal groups in other targets.
Syntax
HRESULT AddPortal(
[in] VDS_OBJECT_ID portalId,
[out] IVdsAsync **ppAsync
);
Parameters
[in] portalId
The VDS_OBJECT_ID of the portal to be added to the portal group.
[out] ppAsync
The address of an IVdsAsync interface pointer. VDS initializes the interface on return. Callers must release the interface. Use this interface to cancel, wait for, or query the status of the operation. If IVdsAsync::Wait is called and a success HRESULT value is returned, the interfaces returned in the VDS_ASYNC_OUTPUT structure must be released by calling the IUnknown::Release method on each interface pointer. However, if Wait returns a failure HRESULT value, or if the pHrResult parameter of Wait receives a failure HRESULT value, the interface pointers in the VDS_ASYNC_OUTPUT structure are NULL and do not need to be released. You can test for success or failure HRESULT values by using the SUCCEEDED and FAILED macros defined in Winerror.h.
Return value
This method can return standard HRESULT values, such as E_INVALIDARG or E_OUTOFMEMORY, and VDS-specific return values. It can also return converted system error codes using the HRESULT_FROM_WIN32 macro. Errors can originate from VDS itself or from the underlying VDS provider that is being used. Possible return values include the following.
| Return code/value | Description |
|---|---|
|
The portal was added successfully to the portal group. |
|
The cache of the provider is corrupted. This indicates a software or communication problem inside a provider that caches information about the attached devices. The caller can use the IVdsHwProvider::Reenumerate method followed by the IVdsHwProvider::Refresh method to restore the cache. |
|
The portal group object is no longer present. |
|
Another operation is in progress. This operation cannot proceed until the previous operations are complete. |
|
The portalID parameter does not refer to an existing object. |
