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 Sense Key is set to RECOVERED

ERROR with the Additional Sense Code set to 5Dh / 00h

(TapeAlert event). The SCSI command with CHECK

CONDITION 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 to poll the

drive. The Sense Key is set to NO SENSE with the Additional

Sense Code set to 5Dh / 00h (TapeAlert event).

The Additional Sense Code of 5Dh / 00h for values 03h and 06h signals that a

TapeAlert occurred. The drive stores information about the event in the

TapeAlert Log page. The setting of the MRIE field does not impact logging of

events in the TapeAlert Log page.
