Function Code H: Test Head
Approximate Run Time = 10 minutes
Total Number of Loops = 10
Function Code
H
performs tests to ensure that the tape drive’s head and
tape-carriage mechanics work correctly.
The diagnostic loops ten times. Press the Unload Button to stop the diagnostic and
exit maintenance mode. Pressing the Unload Button once will abort the test at the
end of the current test loop. Pressing the Unload Button twice will abort the test
immediately.
Attention
For this test, insert only a scratch (blank) data cartridge or a cartridge that
may be overwritten. During the test, the drive overwrites the data on the
cartridge.
1. Place the drive in maintenance mode. For instructions, see “Entering
Maintenance Mode” on page 32.
2.
Press the Unload Button once per second until
H
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 that is not write-protected (or the tape
drive exits maintenance mode). The SCD changes to a flashing
H
. The tape
drive runs the tests.
v If no error is detected, the test will loop and begin again. To stop the loop,
press the Unload Button for one second and release. When the loop ends,
0
temporarily appears in the SCD. The drive rewinds the tape and unloads the
cartridge. The drive then exits maintenance mode.
v If an error is detected the test stops, error code
5
appears in the SCD. To
determine the error, locate
5
in Table 15 on page 75. The drive unloads the
tape cartridge and exits maintenance mode. To clear the error, turn the power
off, then on again.
