If the DLT4000 tape drive fails during POST or operation, use Table 1-1 to
determine the problem and the action to take.
Table 1-1 Troubleshooting
Symptom: Your system does not recognize the DLT4000 tape drive.
Action: Make sure that:
•
The SCSI ID is unique.
•
The SCSI data cable is not loose.
•
The SCSI bus is correctly terminated.
•
You have rebooted the system using the boot -r command.
Symptom: All LEDs on the right- or left-side of the tape drive front panel
blink.
Action: Try to unload the tape and reinitialize the drive by pressing the
Unload button, or turn the drive power off and then on again.
The right- or left-side LEDs stop blinking and the drive tries to
reinitialize. The LEDs should turn on steady again and go off if
the test succeeds.
If all right- or left-side LEDs still blink, the drive has a hardware
failure.
