LogErr Error Log. Not Supported

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 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.

Interval Timer Not Supported.
