220.127.116.11.32.8 IVdsVolume::RemovePlex (Opnum 10)
HRESULT RemovePlex( [in] VDS_OBJECT_ID plexId, [out] IVdsAsync** ppAsync );
ppAsync: A pointer to an IVdsAsync interface that, if the operation is successfully completed, receives the IVdsAsync interface to monitor and control this operation. 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 ppAsync is not NULL.
The server MUST perform the following:
Create a new async object implementing the IVdsAsync interface with an output type of VDS_ASYNCOUT_REMOVEVOLUMEPLEX and set the pointer that ppAsync references to the interface.
If the volume resides on a basic disk, the server MUST return VDS_E_NOT_SUPPORTED (HRESULT of 0x80042400).
Return an HRESULT indicating failure or success. Any errors encountered up through this point in processing the operation are returned in this HRESULT.
The server MUST then perform the following in sequence. Errors generated in this sequence of steps are returned in the pHrResult parameter to the IVdsAsync::Wait or IVdsAsyncQueryStatus methods.
Remove the volume plex that corresponds to the VDS_OBJECT_ID PlexId specifies from this volume.
Remove the corresponding volume plex object from the list of storage management objects.
Set the return code in the async object to an HRESULT indicating failure or success.
If the task completed successfully, set the percentage completed value in the async object to 100.
Set the signal state in the async object to TRUE.
The server MUST update the percentage completed value periodically during the preceding sequence. How often the percentage completed is updated, and at what point in the sequence, is implementation-specific.
