Logs errors that are detected by the miniport driver or HBA.

No return value.

HwDeviceExtension

Identifies the HBA miniport driver's storage for adapter data.

Srb

Points to a SCSI request block if one is associated with the error.

PathId

Identifies the SCSI bus.

TargetId

Identifies the target ID 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 HBA 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 card 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 then results in reduced performance.

UniqueId

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

All real errors should be logged; however, errors such as selection time out or reset detected should not be logged. Recoverable errors should be retried after they have been logged.
