Solving initial startup problems
Table 15 lists initial startup problems and corrective actions.
Table 15. Initial startup problems
Problem Corrective action
The library does not start. Make sure that all power cords are connected to a grounded
electrical outlet.
The library or tape drives do
not respond on the SCSI
bus.
Make sure that each SCSI device on the same SCSI bus has
a unique address and that the last device is correctly
terminated.
During initialization, a
not
ready message is displayed.
Determine the failure type by checking any previous error
codes that were returned to the host system. Correct the
cause of the error.
One or more tape drives fail
to spin up during startup.
Check all SCSI cables and termination at the back of the
library. If this does not solve the problem, replace the tape
drive. See Table 19 on page 43 for more information.
An internal communication
error is reported.
Communication between the robot controller and system
controller board has been lost. Restart the library. If this does
not solve the problem, replace the controller board. See
Table 19 on page 43 for more information.
Solving operator control panel problems
Table 16 lists operator control panel problems and corrective actions.
Table 16. Operator control panel problems
Problem Corrective action
The operator control panel is
blank.
Make sure that the library power is on. If power is on, replace
the power supply. See Table 19 on page 43 for more
information.
The operator control panel
does not respond to the
control buttons.
Confirm that the library power is on. If power is on, replace
the library chassis. See Table 19 on page 43 for more
information.
An error message is
displayed.
Write down all of the message information. Correct the
problem.
