Learn about using maintenance mode functions on the EU11
tape drive.
Performing operations using the front panel
Perform
maintenance operations by pushing the eject button while observing
the status LED and the single-character display.
Entering maintenance mode
The drive must be
in maintenance mode to run drive diagnostics or maintenance functions.
To place the unit in maintenance mode complete the following steps:
- Make sure that no cartridge is in the drive.
- Press and hold the Unload Button for 6 seconds. A 0
is shown in the single-character display (SCD), and the fault light
turns amber.
Note: If a tape cartridge is in the tape drive, the drive ejects
the tape cartridge the first time that you press the Unload button,
and the drive will not be placed in maintenance mode. To continue
placing the drive in maintenance mode, perform the
step 2 again. While in maintenance
mode, the drive does not accept a tape cartridge unless the drive
requests it. The SCD displays a flashing C to indicate that a tape
cartridge needs to be inserted.
Maintenance functions cannot
be performed concurrently with read or write operations. While in
maintenance mode, the drive does not receive commands from the server.
Scrolling through maintenance options
With
the drive in maintenance mode, press the eject button at a rate of
once per second. The single-character display code increments by one
each time you press the eject button.
Note: Do not press the eject
button more frequently than once per second or the selected maintenance
function processes instead of the desired scrolling operation.
After
the last maintenance function is reached, the display code wraps to
0. Unassigned digits (B, D, and G) are not displayed when the options
are incremented.
The following table lists the maintenance functions.

Running a maintenance function
To run the maintenance
function indicated by the character on the single-character display,
press and hold the eject button for 2 seconds. The single digit flashes
the selected maintenance function code during the running of the operation.
If the drive runs the function successfully, the single-character
display indicates 0. If the function fails, the status LED indicates
continuous yellow and the single-character display indicates the reason
for the error by displaying an error code. For more information, see
Table 3.
Exiting maintenance mode
The drive must be
in maintenance mode to run drive diagnostics or maintenance functions.
To
exit maintenance mode, complete the following steps:
- Press and hold the Unload button for 3 or more seconds, and then
release the button to take the drive out of maintenance mode. If no
error is detected, 0 is shown temporarily in the SCD, and then the
SCD goes blank. The drive then exits maintenance mode and the status
light returns to green.
- If an error is detected, the SCD shows an error code but still
exits maintenance mode. To clear the error, turn the drive off and
then on again.
Note: The drive also automatically exits maintenance mode after
it completes a maintenance function or after 10 minutes if no action
has occurred.
Running a dump operation when not in maintenance mode
To
perform a drive dump operation, press and hold the eject button for
10 or more seconds. The microcode goes to its initialized state after
a dump operation.
Note: Data from a dump operation is for use by trained
personnel for problem determination.
