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 is 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.
