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.
