It is important that you select and run the diagnostic tests that meet your needs. This can be achieved by following these steps:
Check Your Operating System
If your operating system will accept commands, go to Choose the Right Diagnostics. If your system is not responding to commands, first, try to execute the shutdown command to stop the operating system. If this does not work, switch off your system's power and go to Loading the Online Diagnostics in Service Mode .
Choose the Right Diagnostics
Even though concurrent diagnostics can test many resources when your operating system is running and users are accessing the system, using the online diagnostics in service mode can isolate and test problems more accurately.
If you want to run the online diagnostics in service mode, then use the shutdown command to stop the operating system, switch off your system's power, and go to Loading the Online Diagnostics in Service Mode. Otherwise, go to Running the Online Diagnostics in Concurrent Mode.
Running the Online Diagnostics in Concurrent ModeRun the concurrent diagnostic program by following these steps:
Enter the diag command to start the diagnostics.
Note: You must either have root user authority or be a user with administrative role 'RunDiagnostics' to run diagnostics. If you are not a root user, you must also have 'system' as primary group and a group set that includes 'shutdown'. Group 'shutdown' is necessary to perform shutdown and reboot operations that are required for certain diagnostic operations. Users in the Run Diagnostics role can change the system configuration, update microcode etc. It is important that users in this role understand the responsibility it requires.To setup a non-root user, Customer Engineer (CE) or Service Support Representative (SSR) who can run diagnostics, create a unique user using System Management Interface Tool (SMIT). The primary group of this user must be 'system'. This user must also have role 'RunDiagnostics' and a group set that includes 'shutdown'.
Wait for the Diagnostic Operating Instructions screen to appear.
The diagnostics programs should display the Diagnostic Operating Instructions screen.
If the appearance of the Diagnostic Operating Instructions screen is distorted or unreadable, you may have a problem with the display console. Go to "Identifying Your Console Display" for directions on correcting display problems. If this section does not help you resolve your display problem, then record and report SRN (Service Request Number) 111-121 to your service representative.
Press the Enter key to continue. The Function Selection screen should be displayed.
If the Function Selection screen does not appear after you press the Enter key, you might have a problem with your keyboard. If you have a tty, you may need to press a key other than the Enter key. Go to Identifying Your Keyboard to continue.
Note: If you select the Online Diagnostic in Service Mode method, you may not be able to test either your system disk or your SCSI adapter. If this occurs, go to Loading the Standalone Diagnostics in Service Mode for a more comprehensive test.
Load the Online Diagnostics by following these steps:
Stop your system with the shutdown command.
If your system has a mode switch, set it to the Service position.
If your system does NOT have a mode switch, and the first device icon or mnemonic displays, press the F6 key on the direct attached keyboard or 6 on the tty keyboard. Enter the password if the password icon or prompt appears.
If the Maintenance menu is displayed, select System Boot-->Boot From List.
Follow any instructions to select a console.
The diagnostics programs should display the Diagnostic Operating Instructions screen.
If the system appears to stop before the Diagnostic Operating Instructions screen screen is displayed, go to Interpret Values in the Operator Display Panel.
If the appearance of the Diagnostic Operating Instructions screen is distorted or unreadable, you may have a problem with the display console. Go to "Identifying Your Console Display" for directions on correcting display problems. If this section does not help you resolve your display problem, then record and report SRN (Service Request Number) 111-121 to your service representative.
Press the Enter key to continue. The Function Selection screen should be displayed.
If the Function Selection screen does not appear after you press the Enter key, you might have a problem with your keyboard. If you have a tty, you may need to press a key other than the Enter key. Go to Identifying Your Keyboard to continue.
If the system appears to stop before the Function Selection screen is displayed, go to Interpret Values in the Operator Panel Display.
Go to Run Diagnostic Routines for information on continuing your diagnostic tests.
Note: If you are using a tty terminal to run standalone diagnostics, check for the following conditions before loading the diagnostics:
The tty terminal must be attached to the S1 port on your system.
The attributes for the terminal must be set to match the defaults of the diagnostics.
For more information about loading diagnostics with a tty, see your system operator's guide. It is important that you set your terminal attributes to work with the diagnostics.
Return to this section when you finish checking the attributes. Record any settings that are changed.
Load the diagnostics by doing the following:
Stop your system with the shutdown command.
If your system has a mode switch, set it to the Service position.
Insert the Standalone Diagnostics media in the proper drive.
If your system does NOT have a mode switch, and the first device icon or mnemonic displays, press the F5 key on the direct attached keyboard or 5 on the tty keyboard. Enter the password if the password icon or prompt appears.
If the Maintenance Menu is displayed, select System Boot-->Boot From List, then continue with this step.
Respond to screen messages, followed by the Enter key. The diagnostics program defines your system console and shows the Diagnostic Operating Instructions screen.
Press the Enter key to continue. The diagnostics program shows the Function Selection screen.
Select Initialize Terminal from the menu on the Function Selection screen.
Enter your terminal type. The diagnostics program initializes your system environment and shows the Function Selection screen again.
Go to Run Diagnostic Routines for information about continuing with your diagnostic tests.
