ScsiPortLogError routine

The ScsiPortLogError routine logs errors to the system event log when a miniport driver or its HBA detects a SCSI error condition.

Syntax


VOID ScsiPortLogError(
  _In_      PVOID HwDeviceExtension,
  _In_opt_  PSCSI_REQUEST_BLOCK Srb,
  _In_      UCHAR PathId,
  _In_      UCHAR TargetId,
  _In_      UCHAR Lun,
  _In_      ULONG ErrorCode,
  _In_      ULONG UniqueId
);

Parameters

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.

Srb [in, optional]

Pointer to a SCSI request block if one is associated with the error. Otherwise, this parameter is NULL.

PathId [in]

Identifies the SCSI bus.

TargetId [in]

Identifies the target controller or device on the bus.

Lun [in]

Identifies the logical unit number of the target device.

ErrorCode [in]

Specifies an error code indicating one of the following values as the type of error.

ValueMeaning

SP_BAD_FW_ERROR

Indicates the driver has detected bad or old firmware. The device will not be used.

SP_BAD_FW_WARNING

Indicates the driver has detected a card with old or bad firmware, which can result in reduced performance or functionality.

SP_BUS_PARITY_ERROR

Indicates a SCSI bus parity error was detected.

SP_BUS_TIME_OUT

Indicates a SCSI bus connection to a logical unit timed out.

SP_INTERNAL_ADAPTER_ERROR

Indicates an internal HBA error was detected.

SP_INVALID_RESELECTION

Indicates a logical unit reselected unexpectedly or with an invalid queue tag.

SP_IRQ_NOT_RESPONDING

Indicates the HBA is not interrupting when expected.

SP_PROTOCOL_ERROR

Indicates the miniport driver detected a SCSI bus protocol error.

SP_REQUEST_TIMEOUT

Indicates an operation to the controller has timed out.

SP_UNEXPECTED_DISCONNECT

Indicates that a target disconnected unexpectedly.

 

UniqueId [in]

Specifies a unique identifier for the error. This value differentiates the current error from other errors with the same ErrorCode. For some miniport drivers, this identifies the line of code where the error was detected. For others, it is additional information returned by the HBA.

Return value

None

Remarks

A miniport driver should log all real hardware errors. However, it should not log common operational errors, such as selection time-outs or bus resets.

Requirements

Header

Srb.h (include Miniport.h or Scsi.h)

Library

Scsiport.lib
