Load a diagnostics program by:
Confirm that your system can start the diagnostics.
Is your operating system accepting commands?
|Yes||Go to the next step, "Choosing Which Diagnostics to Run".|
|No||Attempt to execute the shutdown command to stop the operating system. When complete or if your system is hung, switch off your system's power. Go to "Loading the Standalone Diagnostics in Service Mode".|
Concurrent diagnostics can test many resources while your operating system is running and other users are using the system. Online Diagnostics in Service Mode, however, can isolate and test problems more thoroughly than the concurrent method, but only the diagnostics can be running during this testing.
Do you want to run the Online Diagnostics in Service Mode?
|Yes||Use the shutdown command to stop your operating system, and then switch off your system's power. Go to "Loading the Online Diagnostics in Service Mode".|
|No||Go to the next step, "Running the Online Diagnostics in Concurrent Mode".|
Run the concurrent diagnostic program by doing the following:
Note: You must have root user authority to use the diag command.
|Yes||Press the Enter key to continue with your diagnostics test. The FUNCTION
SELECTION screen appears after you press the Enter key. Go to
Test Options" to continue.
|No||Use the shutdown command to stop the operating system, and then switch off your system's power. Go to "Loading the Online Diagnostics in Service Mode".|
Note: The Online Diagnostic in Service Mode method, while more thorough than the concurrent method, may not allow you to test either your system disk or your SCSI adapter. If not, go to "Loading the Standalone Diagnostics in Service Mode" for a more comprehensive test.
Load the Online Diagnostics using the following steps:
Note: You can use a tty terminal to run standalone diagnostics. Check for the following conditions before loading the diagnostics:
To load the diagnostics with a tty, see "Running the Diagnostic from a tty Terminal" in the Diagnostics chapter of your system operator's guide. Remember to set your terminal attributes to work with the diagnostics.
Load the diagnostics by doing the following:
Note: Step 7 is for diskette users only. Other users should continue with Step 8.
Go to "Responding to Diagnostic Instructions or Messages" if your system does not show the c07 code. Find your symptom and follow the instructions.
Did your system stop with a blank operator panel display and did the DIAGNOSTIC OPERATING INSTRUCTIONS screen appear with no obvious problem on the screen (the text is not distorted and blurred)?
|Yes||Press the Enter key to continue with your diagnostic tests. The FUNCTION SELECTION screen appears after you press the Enter key. Go to "Choose Test Options" to continue with your diagnostic tests.|
|No||If the appearance of the DIAGNOSTIC OPERATING INSTRUCTIONS screen is
either bad (distorted or unreadable) or blank, you might have a problem
with your display console. Go to "Identifying
Your Console Display"
for directions on correcting your display
problem. If identifying your console display does not correct the problem,
record and report SRN 111-121 to your service representative.
If the Maintenance Menu is displayed, select System Boot, then Boot Form List, then continue with this step.
If the FUNCTION SELECTION screen does not appear after you press the Enter key, you might have a problem with your keyboard. Go to "Identifying Your Keyboard" to find the SRN you use to report your keyboard problem.
For all other problems refer to your system guide.
