3.4.5.2.19.3 IVdsPack::QueryVolumes (Opnum 5)

  • Article

The QueryVolumes method retrieves the volumes of a disk pack.

 HRESULT QueryVolumes(
   [out] IEnumVdsObject** ppEnum
 );

ppEnum: A pointer to an IEnumVdsObject interface that, if the operation is successfully completed, receives the IEnumVdsObject interface of the object that contains an enumeration of volume objects in the pack. Callers MUST release the interface when they are done with it.

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 to indicate failure. For the HRESULT values predefined by the Virtual Disk Service Remote Protocol, see section 2.2.3.

When the server receives this message, it MUST validate the following parameter:

  • Verify that ppEnum is not NULL.

The server MUST point ppEnum to an IEnumVdsObject interface that contains the enumeration of volume objects in the list of cached storage management objects that have their pack pointer set to this pack object. The server MUST then return an HRESULT indicating failure or success. For information on enumeration objects, see section 3.4.1.3.
