Interpreting the LTO Status LED

The following table describes the states for the status LED and their
meaning. The LED states are the same for all three types of LTO drive.
When LTO-4 Fibre Channel drives running firmware version 8940 or later
are installed in the library, the LED status information shown on the Drive
Details screen always indicates that the LED is off.
If you need to determine the state of the LED, use the IBM Tape Diagnostic
Tool (ITDT). You can download ITDT directly from www.ibm.com. Once
you are on IBM's web site, search for Tape Diagnostic Tool to locate and
download the software and the user guide. Contact Spectra Guard Support
if you need assistance (see
LED State
Off The drive is powered off or is not assigned to a partition.
Solid The drive is powered on and assigned
to a partition.
If a solid C appears in the single-
character display in conjunction with
the solid green LED, then the drive
needs cleaning.
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.

information about the SCD in the following
sections 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
