continuously or solidly lit for at least 20 minutes, service the LCB as soon as
possible. The library may or may not generate an operator intervention, depending
on the source of the problem.
Attention: Never remove an LCB when its amber LED is solidly lit, unless it has
been solidly lit for at least 20 minutes.
The following table indicates the actions you can take, based on the condition of
the LED.
Table 7-3. Amber LED on an LCB
State of Amber
LED Suggested Service Action
Solid ON for
20+ minutes
Replace the LCB.
1 blink per
second
Check the firmware for the LCB and make sure that you have the most
current firmware available (visit http://www.ibm.com/storage/lto.Donot
replace the LCB. It is unlikely that the LCB hardware is the source of the
problem.
Servicing a Library Control Blade Based on LED Status
When servicing a blade based on the status of an LED:
1. Observe the blinking patterns of the LEDs for at least 30 seconds, and log your
observations in both the operator intervention and the equipment failure report
that you MUST return with the defective part. Accurate reporting of all LED
states for the entire green, amber, and blue set of LEDs is critical for diagnosing
the cause of the problem.
2. Generate a current log of the library, and send it to technical support for
analysis. It is highly recommended that SSRs fill out the information contained
on the “Library Configuration Form” so that data will not be accidentally lost.
Library Configuration Form: Make a copy of this form, fill it out as you are
installing and configuring your library. Update the form each time changes are
made to the library. The information on this form is very important. You can also
save your libraries configuration data from the web user interface (see
“Saving/Restoring System Configuration” on page 7-12). Having the information
on this form will be helpful if a call to IBM Service is necessary. Store this form in
a secure location.
Tape Drive LEDs
Operator interventions typically report all problems related to tape drives,
including error codes and tape alerts. By observing the blinking pattern of LEDs
on tape drives, however, you can discern which operation the tape drive is
currently performing.
