StorPortDeviceReady function (storport.h)

The StorPortDeviceReady routine notifies the port driver that the indicated logical unit is ready to handle new requests.

Syntax

STORPORT_API BOOLEAN StorPortDeviceReady(
  [in] PVOID HwDeviceExtension,
  [in] UCHAR PathId,
  [in] UCHAR TargetId,
  [in] UCHAR Lun
);

Parameters

[in] HwDeviceExtension

A pointer to the hardware device extension. This is a per HBA storage area that the port driver allocates and initializes on behalf of the miniport driver. Miniport drivers usually store HBA-specific information in this extension, such as the state of the HBA and the mapped access ranges for the HBA. This area is available to the miniport driver immediately after the miniport driver calls StorPortInitialize. The port driver frees this memory when it removes the device.

[in] PathId

Identifies the SCSI bus.

[in] TargetId

Identifies the target controller or device on the given buses.

[in] Lun

Identifies the logical unit for the given target controller or device.

Return value

StorPortDeviceReady returns TRUE if the miniport driver succeeded in notifying the port driver, FALSE if not.

Remarks

It is not generally necessary to notify the target device that new requests are required.
