IVdsSubSystem::GetDrive method (vdshwprv.h)
[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]
Returns the specified drive.
Syntax
HRESULT GetDrive(
[in] SHORT sBusNumber,
[in] SHORT sSlotNumber,
[out] IVdsDrive **ppDrive
);
Parameters
[in] sBusNumber
The number of the bus to which the drive is connected.
[in] sSlotNumber
The number of the slot the drive occupies.
[out] ppDrive
The address of an IVdsDrive interface pointer. Callers must release the interface.
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 |
|---|---|
|
This return value signals a software or communication problem inside a provider that caches information about the array. 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 the previous operation or operations are complete. |
Remarks
Because sSlotNumber and sBusNumber identify a drive exclusively, implementers can assign arbitrary (but consistent) values to each as an internal way of identifying the drives. For more information about bus and slot numbers, see the sInternalBusNumber and sSlotNumber members of the VDS_DRIVE_PROP structure.
