Step 003 Step 004 4. 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. AIX or Linux login prompt appears. Record any error messages or codes that are displayed on the screen. If the last error is a POST or firmware error (8-digit) code, look up the error in "Firmware error codes" on page 102. If the last error or is a firmware checkpoint (progress) code (3 or 4 digits), see "Firmware checkpoint (progress) codes" on page 94. Check the BladeCenter management module event log. If an error was recorded by the system, see Chapter 10, "Symptom-to-FRU index," on page 93. Obtaining an SRN/SRC or error code Perform the steps in this section to get a service request number (SRN), or to obtain an SRC or error code. Step 001 Check for the following information: 1. If a firmware checkpoint (progress) code (3 or 4 digits) is displayed, see "Firmware checkpoint (progress) codes" on page 94. 2. If a firmware error code (8 digits) is displayed, see "Firmware error codes" on page 102. 3. If you have an SRN or SRC, see "SRN tables" on page 110. 4. Check the BladeCenter management module event log. If an error was recorded by the system, continue with Step 002 ; then, see "SRN tables" on page 110. 5. If the login prompt appears and you still suspect a problem, continue to Step 002 . 6. If you have none of the above symptoms, go to "Undetermined problems" on page 156. Step 002 Visually check the system for obvious problems such as unplugged power cables or external devices that are powered off. Did you find an obvious problem? No Go to Step 003 . Step 003 Yes Fix the problem. Is the operating system AIX? Step 004 Yes Record any information or messages that may be provided on the system console and then go to Step 005 to perform problem determination procedures. No Go to Step 004 . Is the operating system Linux? Yes Record any information or messages that may be provided on the system console; then go to Step 007 , to perform standalone diagnostics. If you cannot load standalone diagnostics, then answer this question No. No Go to "Undetermined problems" on page 156. 22 BladeCenter JS20 Type 8842: Hardware Maintenance Manual and Troubleshooting Guide
