Note: If a cartridge is in the tape drive, it will eject 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 preceding step. While
in Maintenance Mode, the drive will not accept a cartridge
unless the drive requests it. The SCD will display a flashing
C to indicate a 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 host interface commands from the server.
The drive must be in maintenance mode to run drive diagnostics or
maintenance functions. To exit maintenance mode:
1 Press the Unload button once per second to increment the display
character until 0 displays. Press and hold the Unload button for 3 or
more seconds then release the button to take the drive out of
maintenance mode. If no error is detected, 0 temporarily appears in
the SCD, then goes blank. The drive then exits maintenance mode
and the Ready light will turn On.
2 If an error is detected, the SCD shows an error code but still exits
maintenance mode. To determine the error, locate the code in
Appendix A, Error Codes and
power off, then on again.
Note: The drive also exits maintenance mode automatically after
it completes a maintenance function or after 10 minutes if
no action has occurred.
