LTO-3 Tape Drive Troubleshooting
When drive power is cycled, LTO-3 drives automatically run self-diagnostic tests,
checking memory and sensors, performing motor and servo tests, and testing data
channels to ensure that the drive is functioning within normal parameters.
LTO-3 drives have these troubleshooting tools:
• A light-emitting diode (LED)
• A single-character display (SCD)
If you think that the drive may be faulty, follow these steps:
1. Check the state and color of the drive's LED on the front of the suspect drive.
2. Note the character in the SCD on the front of the suspect drive.
3. Refer to the following tables to interpret these indicators. If the drive is in an
error state, contact Spectra Logic Technical Support.
LTO-3 LEDs
When the LED is off, it means that the unit has no power, is powered off, or is not
assigned to a partition.
Indication
The drive is powered on.
Solid If a solid
display, the drive needs cleaning.
The drive is reading from the tape, writing
to the tape, rewinding the tape, locating
data on the tape, loading the tape, or
unloading the tape.
The status light also flashes green if the
drive contains a cartridge during the
Flashing power-on cycle. In this case, the drive
completes writing the current data and
slowly rewinds the tape (the process may
take up to 13 minutes). The light stops
blinking when the drive completes the
recovery and is ready for a read or write
operation.

LED Color
The drive is powering on or is in maintenance
mode.
One of the following applies:
- If the light flashes once per second, an error
occurred and the tape drive or media may
require service. (Note the code on the single-
character display, then review LTO-2: SCDs/
Error Conditions and Informational Messages
on page 139 to determine the action required.)
- If the light flashes twice per second, the tape
drive is updating firmware.
- If the light flashes four times per second, the
tape drive detected an error and is performing a
firmware recovery. It resets automatically.
