Function code 0: Maintenance mode
Function code
0
makes the drive available for running drive diagnostics or
maintenance functions.
1. Put the drive in Maintenance mode. For instructions, see “Entering
Maintenance mode” on page 25.
2. To exit Maintenance mode, see “Exiting Maintenance mode” on page 25.
The drive exits Maintenance mode automatically after it completes a maintenance
function or after 10 minutes if no action has occurred.
Function code 1: Run drive diagnostics
Approximate Run Time = 5 minutes per loop
Total Number of Loops = 1
Function code
1
runs tests that determine whether the drive can properly load
and unload cartridges and read and write data.
Once you begin this test, the diagnostic begins the loop sequence. Time the first
loop by pressing the Unload button once to stop the diagnostic after the
completion of the first loop, then record the time it takes for the test to complete.
Compare the recorded time with the "Approximate Run Time" above. If the test
runs successfully but the execution time is significantly longer than the
"Approximate Run Time", run “Function code F: Write performance test” on page
34. If the Write performance test fails, replace the media and exit Maintenance
mode.
Attention: For this test, insert only a scratch (blank) data cartridge or a cartridge
that can be overwritten. During the test, the drive overwrites the data on the
cartridge.
Note:
If you inserted an invalid tape cartridge (for example, Gen 2 or WORM
media), error code
J
or
7
appears in the SCD. If you inserted a
write-protected cartridge, or the media has read-only compatibility (for
example, Gen 3 media), 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.
To execute Function code 1: Run drive diagnostics, complete the following steps:
1. Put the drive in Maintenance mode. For instructions, see “Entering
Maintenance mode” on page 25.
2. Press the Unload button once per second until
1
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 3 or more seconds, then release it to
select function
1
. Wait for the SCD to change to a flashing
C
.
