VDS_PORT_NOTIFICATION structure (vdshwprv.h)
[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]
Defines the details of controller port events.
Syntax
typedef struct _VDS_PORT_NOTIFICATION {
ULONG ulEvent;
VDS_OBJECT_ID portId;
} VDS_PORT_NOTIFICATION;
Members
ulEvent
Determines the controller port event for which an application will be notified, as one of the following values.
| Value | Meaning |
|---|---|
|
A controller port is reported as physically present on the subsystem. The VDS_PORT_STATUS value associated with this notification should be any value except VDS_PRS_REMOVED. |
|
A controller, and therefore its port, were physically unplugged from the subsystem. The VDS_PORT_STATUS value should be VDS_PRS_UNKNOWN or VDS_PRS_REMOVED. |
|
A member of the VDS_PORT_PROP structure changed.
Windows Server 2008, Windows Vista and Windows Server 2003 R2: This value is not supported. |
|
A controller port is physically present but not available for use. For example, either the controller or the port itself is set to inactive. The VDS_PORT_STATUS value should be VDS_PRS_FAILED (removed from use because of failure), VDS_PRS_OFFLINE (not failed, but not in use either), VDS_PRS_NOT_READY, or VDS_PRS_UNKNOWN.
Windows Server 2008, Windows Vista and Windows Server 2003 R2: This value is not supported. |
portId
The VDS_OBJECT_ID of the controller port that triggered the event.
Remarks
The VDS_NOTIFICATION structure includes this structure as a member.
An application can receive disk events by implementing the IVdsAdviseSink interface and passing the interface pointer as an argument to the IVdsService::Advise method.
To get the port object, use the IVdsService::GetObject method. You can then use the IVdsControllerPort::GetProperties method to get the port properties.
