LTO Drive LEDs
When the LED is off, it means that the unit has no power or is powered off.
LED Color
Green
Amber
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.
Flashing
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 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.
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 Drive SCDs
on page 70
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.
