MRIE Method for Reporting Informational Exceptions. The drive uses the contents of this field
to report information about exception conditions. The available methods are:
Value Method
00h No reporting of Informational Exception Conditions. The drive does not
report information exception conditions.
03h Conditionally Generate Recovered Error. The drive reports informational
exception conditions, if such reports of recovered errors are allowed, by
returning
CHECK CONDITION status on the next SCSI command (except
INQUIRY and REQUEST SENSE commands) following detection of the
condition. The drive sets the Sense Key to
RECOVERED ERROR with an
Additional Sense Code of 5Dh / 00h (TapeAlert Event). The SCSI
command with the
CHECK CONDITION status completes without error
before the report of any exception condition and does not need to be
repeated.
04h Unconditionally Generate Recovered Error. The drive reports
informational exception conditions by returning
CHECK CONDITION status
on the next SCSI command (except
INQUIRY and REQUEST SENSE
commands) following detection of the condition. The drive sets the Sense
Key to
RECOVERED ERROR with an Additional Sense Code of 5Dh / 00h
(TapeAlert Event). The SCSI command with the
CHECK CONDITION status
completes without error before the report of any exception condition and
does not need to be repeated.
06h Only Report Informational Exception Condition on Request. The drive
preserves information exception data. To access the data, issue an
unsolicited
REQUEST SENSE command. The drive sets the Sense Key to
NO SENSE with an Additional Sense Code of 5Dh / 00h (TapeAlert Event).
The Additional Sense Code of 5Dh / 00h for values 03h, 04h, and 06h signals that a
TapeAlert event occurred. Information about the event is stored in the TapeAlert Log
page. The setting of the MRIE field does not impact logging of events in the TapeAlert
Log page.

Must be set to 0.
