Parameter Data Formats

The log errors bit (LogErr) of zero indicates that the logging of informational exception conditions within a target is vendor specific. A LogErr bit of one indicates the target logs informational exception conditions.

A Test bit of one creates a false device failure at the next interval time, if the DExcpt bit is not set. When the Test bit is one, the MRIE and Report count fields apply as if the Test bit were zero. The false device failure is reported with an additional sense code of FAILURE PREDICTION THRESHOLD EXCEEDED [=50-FF]. If both the Test and the DExcpt bits are one, the device server terminate the MODE SELECT command with CHECK CONDITION status. The sense key is set to ILLEGAL REQUEST [=5] with the additional sense code set to INVALID FIELD IN PARAMETER LIST [=26-05]. A Test bit of zero instructs the device server not to generate any false device faulure notifications.

A disable exception control (DExcpt) bit of zero indicates information exception operations is enabled. The reporting of information exception conditions when the "DExcpt" bit is set to zero is determined from the method of reporting informational exceptions field. A "DExcpt" bit of one indicates the target disables all information exception operations. The method of reporting informational exceptions field is ignored when "DExcpt" is set to one.

An enable warning (EWASC) bit of zero indicates the target disables reporting of the warning. The "MRIE" field is ignored when "DExcpt" is set to one and "EWASC" is set to zero. An "EWASC" bit of one indicates warning reporting is enabled. The method for reporting the warning when the "EWASC" bit is set to one is determined from the "MRIE" field.

If background functions are supported, an Enable Background Function (EBF) bit of one indicates the target enables background functions. An "EBF" bit of zero indicates the target disables the functions.

The IDD disregards the specified value and operates according to the "Default" value (="0").

A Performance (Perf) bit of zero indicates that informational exception operations that are the cause of delays are acceptable. A Perf bit of one indicates the target is not cause delays while doing informational exception operations. A Perf bit set to one may cause the target to disable some or all of the informational exceptions operations, thereby limiting the reporting of informational exception conditions.

The Method of Reporting Informational Exceptions (MRIE) field indicates the methods that is used by the target to report informational exception conditions. The priority of reporting multiple informational exceptions is vendor specific.
