AIX fast-path problem isolation

Use this information to help you isolate a hardware problem and the server is running the AIX(R) operating system.

In most cases, AIX diagnostics are performed through automatic error log analysis. In some cases, these procedures direct you to run online diagnostics. Standalone diagnostics should only be used if you are unable to boot AIX or are otherwise specifically directed to do so.

Notes:
  1. If the server or partition has an external SCSI disk drive enclosure attached and you have not been able to find a reference code or other symptom, go to isolates/startmap.dita.
  2. If you are servicing an SP(TM) system, go to the Start of Call MAP 100 in the SP System Service Guide.
  3. If you are servicing a clustered server, go to the Start of Call MAP 100 in the Clustered Installation and Service Guide.
  4. If you are servicing a clustered server that has InfiniBand (IB) switch networks, go to the Guide to Clustering systems using InfiniBand (IB) hardwareisolates/referenceinfiniband.dita and open the book entitled Guide to Clustering systems using InfiniBand (IB) hardware.

Note:
If you already know the reference code or have another symptom other than a reference code, go directly to the AIX fast path table.

Use the following procedure to display or confirm a previously reported reference code including an SRN.

  1. Log into the AIX operating system as the root user, or use the CE login. If you need assistance, contact the system operator.
  2. Enter the diag command. The diag command allows you to load the diagnostic controller and display the online diagnostic menus.
  3. Press Enter. This opens the FUNCTION SELECTION menu.
  4. Select Task Selection.
  5. Select Display Previous Diagnostic Results.
  6. Select DISPLAY DIAGNOSTIC LOG SUMMARY. A display diagnostic log summary table is shown with a time ordered table of events from the error log.
  7. Look for the most recent S entry in the T column. The most recent S entry is the one closest to the beginning of the DISPLAY DIAGNOSTIC LOG SUMMARY table.
  8. Move your cursor over the row containing the S entry and press Enter.
  9. Press F7 to Commit.

    A screen containing details from the table is displayed; look for the reference code (SRN or SRC) entry. The SRN or SRC entry is shown near the bottom of the screen.

  10. Record the reference code.

    The following example, which shows the details of an SRN, is similar to what you should see on your terminal when you perform the above procedure.
