Chapter 9 – Troubleshooting

83

When drive power is cycled, LTO 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 drives have these troubleshooting tools:

ƒ A light-emitting diode (LED)
ƒ 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, and note the character in the SCD. To 

check these indicators, you can:

ƒ Look at the front of the suspect drive.
ƒ Look at the Drive Details screen on the LC or RLC.

2. Refer to the tables on the following pages to interpret these indicators.

LTO Drive LEDs   When the LED is off, it means that the unit has no power, is powered 
off, or is not assigned to a partition.

Note:

Only LTO-2 and LTO-3 drive LEDs are described in the Drive Details 
screen on the library’s LC or RLC.

LTO-4 drives do have the LEDs on the front of the drives; you simply have 
to view them through the window on the front of the library. If the 
robotics are in the way and you cannot see them, you may have to open 
the library door.

Green

Solid

The drive is powered on.

If a solid C appears in the single-
character display in conjunction with 
the solid green LED, then the drive 
needs cleaning.

The drive is powering on or is in 
maintenance mode.
