Show AIX operator panel status

Question

Is possible to see codes on the operator panel of P5 IBM workstation from console?

Answer 1

EDIT: Some parts omitted on how to change the system attention indicator after OP clarified that he only wants to see the codes shown on the operator panel data data field.

Yes it is possible to show the status of the system attention indicator. You can either do that via diag command interactively via going to

=> Task Selection (Diagnostics, Advanced Diagnostics, Service Aids, etc.)
==> Identify and Attention Indicators

but I find it easier to directly run the command for the two LEDs. Documentation on those binaries is pretty sparse, but can still be found at the Infocenter under AIX tasks and service aids

You're looking for usysfault:

Fault indicators This task is only available through a command line interface. It is not available from the diagnostic menu nor from stand-alone diagnostics.

The fault indicators are used to identify a fault with the system. These indicators may be set automatically by hardware, firmware, or diagnostics when a fault is detected in the system.

The System Attention Indicator is turned off when a Log Repair Action is performed. All other Fault Indicators are turned off when the failing unit is repaired or replaced. After a serviceable event is complete, do a System Verification to verify the fix. Also, do a Log Repair Action if the test on the resource was good, and that resource had an entry in the error log.

For additional information concerning the use of these indicators, refer to the system unit service information. Note: The AIX command does not allow you to set the fault indicators to the fault state. Use the following command syntax:

/usr/lpp/diagnostics/bin/usysfault [-s normal] [-l location code | -d
devicename] /usr/lpp/diagnostics/bin/usysfault [-t]
Flag 
   Description
-s normal Sets the fault indicator to the normal state.
-l location code Identifies the resource by physical location code.
-d device name Identifies the resource by device name.
-t Displays a list of all supported fault indicators by physical location codes.
   When the command is used without the -s flag, the
   current state of the indicator is displayed as normal or fault.

When the command is used without the -l or -d flag, the System
Attention Indicator is used.

Use the -l or -d flags only in systems that have more than one fault
indicator.

Note: See also the Identify and system attention indicators.

So in general you could run e.g. /usr/lpp/diagnostics/bin/usysfault -s normal to set the system attention indicator back to normal state again, or /usr/lpp/diagnostics/bin/usysfault -t to see a list of available hardware indicators. Although I'm wondering, usually you can either do this easily via an HMC (if you're using one) or it is also automatically done after a part/hardware replacement when you commit the repair action to the log.

So my question would be "Are you sure that you only want to disable the attention indicator?"
