Caution:
Even though no data is written during this test, it is
recommended that you use a blank (scratch) cartridge for
this test.
Note: If you inserted an invalid tape cartridge, error code J or 7
appears in the SCD. If you inserted a write-protected cartridge,
or the media has read-only compatibility, error code P appears
in the SCD. In either case, the tape drive unloads the cartridge
and exits Maintenance Mode after the cartridge is removed.
1 Place the drive in Maintenance Mode. For instructions, see Entering
Maintenance Mode on page 47.
2 Press the Unload button once per second until L appears in the
SCD. (If you cycle past the desired code, press the Unload button
once per second until the code reappears.)
3 Press and hold the Unload button for three or more seconds, then
release it to select the function. The SCD changes to a flashing C .
4 Insert a scratch (blank) data cartridge. The SCD changes to a
flashing L and the tape drive runs the tests.
• If no error is detected, the diagnostic will loop and begin again.
To stop the loop, press the Unload button for one second and
release. When the diagnostic ends, 0 temporarily appears in the
SCD, and the tape drive exits Maintenance Mode.
• If an error is detected, the Fault light flashes and the drive posts
an error code to the SCD. To determine the error, locate the
code in Appendix A, Error Codes and Messages . To clear the
error either turn the power off and then on again, or reboot the
drive by pressing and holding the Unload button for 10
seconds.
Function Code P: Post
Error Reporting
Enabled
When Post Error Reporting is enabled, deferred-check conditions are
reported to the host and temporary errors are reported in the sense
data. Function Code P will be displayed in Maintenance Mode when
the drive has Post Error Reporting enabled.
This selection is normally used as a request from support personnel.
