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