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[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]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
VDS_E_PROVIDER_CACHE_CORRUPT
0x8004241FL
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.
VDS_E_OBJECT_DELETED
0x8004240BL
The subsystem object is no longer present.
VDS_E_OBJECT_STATUS_FAILED
0x80042431L
The subsystem is in a failed state and is unable to perform the requested operation.
VDS_E_ANOTHER_CALL_IN_PROGRESS
0x80042404L
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.
