Press Unload to stop the diagnostic test and exit Maintenance mode. Pressing Unload once stops the test
at the end of the current test loop. Pressing Unload twice stops the test immediately. Wait for the drive to
rewind the tape and unload the cartridge.
Attention: 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 23.
2.
Press Unload once per second until
L
displays in the SCD. (If you cycle past the wanted code, press
Unload once per second until the code reappears.)
3. Press and hold Unload for three or more seconds, then release it to select the function. The SCD
changes to a flashing
C
, requesting a cartridge.
4. Insert a scratch (blank) data cartridge. The SCD changes to a flashing
L
and the tape drive runs the
tests.
v If no error is detected, the diagnostic test loops and begin again. To stop the loop, press Unload for
1 second and release. When the loop ends,
0
temporarily displays in the SCD, and the tape drive
exits Maintenance mode.
v 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 Table 17 on page 65. To clear the error either turn the power
off and then on again, or reboot the drive by pressing and holding Unload 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
is displayed in Maintenance mode when the
drive has Post Error Reporting enabled.
This selection is normally used as a request from support personnel.
1. Place the drive in Maintenance mode. For instructions, see “Entering Maintenance mode” on page 23.

Press Unload once per second until either
P
or
U
displays in the SCD.
P
or
U
displays in the
SCD to indicate the current setting for Post Error Reporting. If you cycle past the desired code, press
Unload
once per second until the code reappears.

instructions, see “Exiting Maintenance mode” on page 23.
4. To disable Post Error Reporting, press and hold Unload for 3 seconds while
