AIX and Linux problem analysis

You can use this procedure to find information about a problem with your server hardware that is running the AIX® or Linux operating system.

1. Is the operating system operational?

   Yes: Continue with the next step. No: Go to step 11 of the Beginning problem analysis topic to diagnose the problem.

2. Are any messages (for example, a device is not available or reporting errors) related to this problem displayed on the system console or sent to you in email that provides a reference code?
   Note: A reference code can be an 8 character system reference code (SRC) or an service request number (SRN) of 5, 6, or 7 characters, with or without a hyphen.

   Yes: Continue with the next step. No: Go to step 4.

3. The reference code description might provide information or an action that you can take to correct the failure.

   Go to the Reference code finder and type the reference code in the field provided. Read the reference code description and return here. Do not take any other action at this time. Was there a reference code description that enabled you to resolve the problem?

   Yes: This ends the procedure. No: Continue with the next step.

4. Are you running Linux?

   Yes: Continue with the next step. No: Go to step 6.

5. To locate the error information in a system or logical partition running the Linux operating system, complete these steps:
   Note: Before proceeding with this step, ensure that the diagnostics package is installed on the system.

   Log in as root user. At the command line, type grep RTAS /var/log/platform and press Enter. Look for the most recent entry that contains a reference code. Continue with step 8.

6. To locate the error information in a system or logical partition running AIX, complete these steps:

   Log in to the AIX operating system as root user, or use CE login. If you need help, contact the system administrator. Type diag to load the diagnostic controller, and display the online diagnostic menus. From the Function selection menu, select Task selection. From the Task selection list menu, select Display previous diagnostic results. From the Previous diagnostic results menu, select Display diagnostic log summary. Continue with the next step.

7. A display diagnostic log is shown with a time ordered table of events from the error log.

   Look in the T column for the most recent entry that has an S entry. Press Enter to select the row in the table and then select Commit. The details of this entry from the table are shown; look for the SRN entry near the end of the entry and record the information shown. Continue with the next step.

8. Do you find a serviceable event or an open problem near the time of the failure?

   Yes: Continue with the next step. No: Contact your hardware service provider.

9. The reference code description might provide information or an action that you can take to correct the failure.

   Go to the Reference code finder and type the reference code in the field provided. Read the reference code description and return here. Do not take any other action at this time. Was there a reference code description that enabled you to resolve the problem?

   Yes: This ends the procedure. No: Continue with the next step.

10. Service is required to resolve the error. Collect as much error data as possible and record it. You and your service provider will develop a corrective action to resolve the problem based on the following guidelines:

    If a field-replaceable unit (FRU) location code is provided in the serviceable event view or control panel, that location should be used to determine which FRU to replace. If an isolation procedure is listed for the reference code in the reference code lookup information, include it as a corrective action even if it is not listed in the serviceable event view or control panel. If any FRUs are marked for block replacement, replace all FRUs in the block replacement group at the same time. From the Error Event Log view, complete the following steps: Record the reference code. Record the error details. Contact your service provider. This ends the procedure.
