Eliminate the yellow alarm light on IBM p750 small computer [easy to understand]

Hello everyone , I meet you again , I'm your friend, Quan Jun .

IBM How to solve the problem of the yellow light on the small machine ？

Description of the warning lamp ：

(1) The hardware failure alarm lamp is a light-emitting diode , It indicates that the system has detected a hardware failure , Administrators should pay attention to .

(2) The hardware fault alarm light is very sensitive , In many cases, it doesn't light up until the hardware fails ,

For example, hot plug some signal wires or cables , Abnormal shutdown of the user may cause the alarm light to light .

(3) The administrator should first check the system error log errpt, See if there is really a hardware error .

without , Then you can turn off the light first , If there is really a hardware problem , It will light up again .

(4) about P5 The server , There are two ways to turn off the yellow warning light , adopt ASMI perhaps HMC.

First of all, we need to determine whether it is because IBM The small machine is a single power supply , Just cause the yellow light （ This happens from time to time .）

Again, generally, the yellow light is caused by hardware problems or hardware configurations with potential safety hazards .

First step ： First, diagnose the hardware

Diagnostic system , Determine whether there is a hardware failure ：

1、Root User execution diag;

2、 After returning , Go to No 2 term ,advanced diagnostics routines;

3、 choose system verification;

4、 choose all resources, enter ;

5、 Press F7（ or esc+7） Perform the test ;

6、 Look at the results , Is there a fault . If there is a fault , Record faults and errpt–a, Do it again. .

The second step ： If there is no fault or the fault is solved, the yellow light still does not go out , Clear the warning lamp .

Method 1 ： adopt diag eliminate

1、Root User execution diag;

2、 After returning , Go to No 3 term ,Task Selection (Diagnostics, Advanced Diagnostics, Service Aids, etc.);

3、 choose Identify and Attention Indicators;（ notes ： This machine does not have this option , example H50）

4、Set System Attention Indicator to Normal or Set ALL Identify Indicators to NORMAL, enter ;

5、 Press F7（ or esc+7） To perform .

（ Add ： stay diag Options Task Selection (Diagnostics, Advanced Diagnostics, Service Aids, etc.) There is a menu under ：

Log Repair Action

After entering , Choose sys0 and sysplanar0, And press F7 or ESC+7 perform , So the yellow light goes out ！！！）

Method 2 ：

perform # /usr/lpp/diagnostics/bin/usysfault -s normal

Introduce ： This situation is only a temporary solution , The goal is to turn off the yellow light by force . Before long, the yellow light will be on

Method 3 ： adopt HMC Turn off the warning light

(1) stay HMC On the console , Select the left column Serivce Applications -> Serivce Focal Point

On the right side Serivce Focal Point The page of .

(2) choice Service Utilities, Pop up the information box of the server .

Select the server to manage , And then choose “Selected” -> System Attention LED…

(3) Select the to manage Lpar. And then choose “Partition Operations” -> Deactivate partition LED.

Method four ： adopt ASMI Turn off the warning light

(1) use first admin The user logs in to ASMI Interface .( Method reference 4)

(2) an System Configuration -> System Indicator -> System Attention Indicator

And then click “Turn off the system attention indicator” that will do .

（ Add ： stay diag Options Task Selection (Diagnostics, Advanced Diagnostics, Service Aids, etc.) There is a menu under ：

Log Repair Action

After entering , Choose sys0 and sysplanar0, And press F7 or ESC+7 perform , So the yellow light goes out ！！！）

stay P750 Upper is entry ASM Operation page , an Collapse all menus–System Configuration–Service Indicators–System Information Indicator You can operate to turn off the warning indicator .
