ScsiPortLogError logs errors to the system event log when a miniport driver or its HBA detects a SCSI error condition.
Parameters
HwDeviceExtension
Points to the miniport driver’s per-HBA storage area.
Srb
Points to a SCSI request block if one is associated with the error. Otherwise, this parameter is NULL.
PathId
Identifies the SCSI bus.
TargetId
Identifies the target controller or device on the bus.
Lun
Identifies the logical unit number of the target device.
ErrorCode
Specifies an error code indicating one of the following values as the type of error:
| Values | Meaning |
| SP_PROTOCOL_ERROR | Indicates the miniport driver detected a SCSI bus protocol error. |
| SP_BUS_PARITY_ERROR | Indicates a SCSI bus parity error was detected. |
| SP_INTERNAL_ADAPTER_ERROR | Indicates an internal HBA error was detected. |
| SP_UNEXPECTED_DISCONNECT | Indicates that a target disconnected unexpectedly. |
| SP_INVALID_RESELECTION | Indicates a logical unit reselected unexpectedly or with an invalid queue tag. |
| SP_BUS_TIME_OUT | Indicates a SCSI bus connection to a logical unit timed out. |
| SP_REQUEST_TIMEOUT | Indicates an operation to the controller has timed out. |
| SP_IRQ_NOT_RESPONDING | Indicates the HBA is not interrupting when expected. |
| 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. |
UniqueId
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.
Comments
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 it detects.
