Step 005 Step 006 Step 007 Perform the following procedure for problem determination. Note: When possible, run AIX Online Diagnostics in Concurrent Mode. AIX Online diagnostics perform additional functions, compared to standalone diagnostics CD. 1. Perform the AIX online concurrent mode diagnostics for Problem Determination, see "Performing AIX online concurrent mode diagnostics for problem determination" on page 25. Record any diagnostic results and utilize the "SRN tables" on page 110 to identify the failing component. Note: If you have replaced the failing component then to verify the repair go to "Verifying the replacement part using AIX diagnostics" on page 30. 2. If you cannot perform AIX concurrent online diagnostics then continue to Step 006 . Perform the following steps: 1. Turn off the system unit power and wait 45 seconds before proceeding. 2. Turn on the system unit power. 3. Start the Serial Over Lan (SOL) console for the blade server to be tested and check for the following responses: a. Progress codes are displayed on the console. b. Record any messages or diagnostic information that may be displayed on the system console. 4. Load the standalone diagnostics CD-ROM. Go to "Running the standalone diagnostics from CD-ROM" on page 25 or "Running standalone diagnostics from a management (NIM) server" on page 68. 5. If you have replaced the failing component then to verify the repair go to "Verifying the replacement part using AIX diagnostics" on page 30. 6. If you are still having a problem or think you still have a problem call the support center. This ends the AIX procedure. If the operating system is Linux then perform the following: 1. Turn off the system unit power and wait 45 seconds before proceeding. 2. Turn on the system unit power. 3. Start the Serial Over Lan (SOL) console for the blade server to be tested and check for the following responses: a. Progress codes are displayed on the console. b. Record any messages or diagnostic information that may be displayed on the system console. Continue with step 008 . Chapter 4. Problem determination procedures for AIX and Linux 23
