ScsiPortNotification (NotificationType = ResetDetected) routine

The ScsiPortNotification routine informs the operating system-specific port driver of certain events, such as when a miniport driver completes a request or is ready to start another SRB, as well as when the HBA indicates certain SCSI error conditions that occurred during an operation.

Note  The SCSI port driver and SCSI miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.
 

Syntax


VOID ScsiPortNotification(
  _In_ SCSI_NOTIFICATION_TYPE NotificationType,
  _In_ PVOID                  HwDeviceExtension
);

Parameters

NotificationType [in]

Specifies the type of notification. A NotificationType of ResetDetected indicates that the HBA has detected a reset on the SCSI bus. After this notification, the miniport driver is still responsible for completing any active requests. The SCSI port driver will manage all required bus-reset delays..

HwDeviceExtension [in]

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 HBA's mapped access ranges. This area is available to the miniport driver in the DeviceExtension->HwDeviceExtension member of the HBA's device object immediately after the miniport driver calls ScsiPortInitialize. The port driver frees this memory when it removes the device.

Return value

None
