This option is used by service personnel to dump the SPCN trace data from the system unit or an I/O
subsystem to gather additional debug information.
To dump the SPCN trace data for the processor subsystem (CEC drawer), enter 0 when prompted for
the SPCN drawer number and enter d0 when prompted for the unit address.
To dump the SPCN trace data for an I/O subsystem, the drawer number must be determined. This can
be done by either:
If the system is booted into AIX, use the "Identify and System Attention Indicators" task to correlate
–
a drawer and its physical location code (for example, U0.2). Due to the drawer addressing scheme
that is used by the SPCN firmware, the drawer numbers may not match the cabling in a particular
RIO loop. For example, do not assume that the first drawer in the loop will be drawer number 2
(which corresponds to a physical location code of U0.2).
– If the system can be booted to the open firmware prompt, enter FRU-LER-MENU at the prompt. Use the
menu to flash the identify indicator on a drawer.
To dump the data for an I/O drawer, enter the drawer number when prompted, then enter 10 for the
unit address as shown in the example below:
Enter the SPCN drawer number:
Enter the Unit Address: 10
Note: It may take up to 5 minutes for the trace data to be dumped to the screen.
The SPCN trace data will be displayed on the screen. An example of this output follows.

v LED Indicator Menu
This menu displays the state of the processor subsystem disturbance/system attention LED and the
fault/identify LED on the I/O subsystem(s). Use this menu to toggle the attention/fault LEDs between
identify (blinking) and off. Option 1 is only available when the system is in the error state (the CEC is
powered on and the service processor menus are available). It is not available when the system is in
standby. An example of this menu follows:
