Chapter 5. AIX online, standalone and verification procedures This chapter describes the procedures for performing online concurrent and CD-based diagnostics, and replacement part verification for an AIX operating system. Performing AIX online concurrent mode diagnostics for problem determination Perform the following steps to run online diagnostics in concurrent mode: 1. Log in to the AIX operating system as root user, or use CE login. If you need help, contact the system operator. 2. Enter the diag command to load the diagnostic controller, and display the online diagnostic menus. 3. At the Function Selection menu, select Diagnostic Routines. 4. At the diagnostic mode selection menu, select problem determination. 5. When the Diagnostic Selection menu is displayed, choose a resource or all resources to be tested. 6. After selecting the resource that you want to test, select Commit (PF7 = F7). The resources will then be tested. 7. If any SRNs or firmware error codes are displayed, record all information provided from the diagnostic results; then, go to the SRN tables. If ″No trouble found″ is displayed, continue to next step. 8. When testing is complete, press F3 to return to the Diagnostic Operating Instructions display. 9. Press Ctrl+D to log off from root user or CE login. 10. When finished, contact your hardware service provider with any information you received during the diagnostics, including service request numbers (SRNs) or firmware error codes. Running the standalone diagnostics from CD-ROM The AIX diagnostics can be downloaded from the World Wide Web at http://techsupport.services.ibm.com/server/mdownload/diags/download. Note: Select the diagnostics that indicate JS20 support. To run standalone diagnostics in service mode, complete the following steps: Step 001 Verify with the system administrator and systems users that the system unit may be shut down. Stop all programs including the operating system (refer to the AIX operating system documentation for information on the shutdown command). Make the CD drive available to the system on which you want to run standalone diagnostics (see the BladeCenter Management Module Operations Guide for more information). Step 002 Before attempting to load standalone CD diagnostic, make sure you are at the latest firmware level (xx.xx) before continuing. Step 003 Log in to the management module. Step 004 Enable SOL for the JS20 Blade to be tested. © Copyright IBM Corp. 2003 25
