Table 19 describes the sense keys.
Table 19 Sense Key
Field Definitions
Sense Key Definition
0h
No Sense. This is an indicator that the drive did not have an error but that the
host system may have sent an incorrect command or that a field in the
changing parameters information was not correct. This is also an indicator that
a request to move the tape past an EOD or a read of a filemark may have been
attempted.
1h
Recovered Error. The drive had a recoverable error. This is one in which the
drive detected something that may not be correct, but that the problem would
not prevent the drive from functioning correctly. It may be just an indicator of
an event that the drive was able to correct. For example, a Cleaning Requested
status shows that the drive wants a cleaning tape used, but will still function
correctly without it. This sense key will only be recorded in the logs if it is a
Cleaning Requested condition.
2h
Not Ready. The drive is not ready for tape functionality. This is not reported in
the drive log pages.
3h
Medium Error. The drive was not able to read or write successfully to the tape.
Look at the Event Logs and correlate the events with media and system logs to
determine if this is due to media or the drive. This sense key is recorded in the
drive logs.
4h
Hardware Error. The drive has detected an error condition related to the
hardware. You will need to refer to the sense Key and ASCQ, along with other
event logs to best understand the error. Based on the log information, replace
the appropriate component. This sense key does get logged each time it is
reported.
5h
Illegal Request. The requested command had an incorrect parameter defined
and you will need to review the actual command and parameter to determine
what was wrong. This is not logged in the drive logs.
