IVdsSubSystemIscsi::QueryTargets 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[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]
Returns an object that enumerates the iSCSI targets of the subsystem.
Syntax
HRESULT QueryTargets(
[out] IEnumVdsObject **ppEnum
);
Parameters
[out] ppEnum
The address of an IEnumVdsObject interface pointer that can be used to enumerate the iSCSI targets as target objects. For more information, see Working with Enumeration Objects. Callers must release the interface and each of the target objects when they are no longer needed by calling the IUnknown::Release method.
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 enumeration of targets was successfully returned. If the subsystem has no iSCSI targets, the enumeration is empty. |
|
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 subsystem object is no longer present. |
|
The subsystem is in a failed state and is unable to perform the requested operation. |
|
Another operation is in progress. This operation cannot proceed until previous operations are complete. |
