Action: In all cases, action depends on the device class and operating system.
Code Meaning Comments
37 00 Rounded parameter The drive needs to round off the value of a parameter
sent by
MODE SELECT because it cannot store it to the
degree of accuracy sent by the command.
5D 00 Failure prediction threshold
exceeded
Failure Prediction thresholds have been exceeded
indicating that TapeAlert flags have been activated.
Action: Retrieve the TapeAlert log page to find out which flag
has been activated and advise the user accordingly.
5D FF Failure prediction threshold
exceeded (false)
The Informational Exceptions Mode page has been sent
with the Test field set to 1 and the DExcpt field to 0,
causing the drive to generate a false informational
exception condition (a false device failure).
Action: Since the function of the Test field is simply to test that an
informational exception condition will produce a
CHECK
CONDITION
and that the exception will be reported to
the TapeAlert log, no action is necessary.
Code Meaning Comments
04 00 LUN not ready, no cause
to report
This is set if an unload is occurring with immediate report
on, or initiated through the front panel, or a different host
initiated the command. It is present for the duration of
the unload or eject, after which the additional sense
changes to 3A 00h (medium not present) or 0402h
(logical unit not ready, initializing command required).
Action: 1. Issue a message to the console stating that the tape is
currently being unloaded from the drive.
2. Poll the drive until the additional sense changes to
3A 00h or 04 02h.
3. Instruct the user what to do, based on the application
and the previous sequence of commands.
4. Depending on the application, the software may
terminate the current I/O.
