Software problemsUse this information to recognize software problem symptoms and to take corrective actions.v Follow the suggested actions in the order in which they are listed in the Action column until the problem issolved.v See Chapter 7, “Parts listing for IBM Flex System p260 and p460 Compute Nodes,” on page 97 to determinewhich components are CRUs and which components are FRUs.v If an action step is preceded by Trained service technician only, that step must be performed only by a trainedservice technician.Symptom ActionYou suspect a softwareproblem. 1. To determine whether the problem is caused by the software, complete thefollowing items:v The compute node has the minimum memory that is needed to use thesoftware. For memory requirements, see the information that comes with thesoftware.Note: If you have just installed an adapter or memory, the compute nodemight have a memory-address conflict.v The software is designed to operate on the compute node.v Other software works on the compute node.v The software works on another compute node.2. If you received any error messages when using the software, see theinformation that comes with the software for a description of the messages andsuggested solutions to the problem.3. Contact your place of purchase of the software.4. To check the operating system logs for information about the source of theerror, first check the ServerProven plan and then complete the following items:a. For AIX: To view a summary of the error log, use the errpt command. Toview a formatted report of the data for the errors in the log, use theerrpt-a command.b. For Linux: The /var/log/messages text file should be retrieved and filteredor viewed as necessary. There are no standardized analysis tools, butscripts can be written to simplify the view to what you need.c. For IBM i: Existing problem log entries are available through the WRKPRBcommand. To create a new log entry, use the ANZPRB command.Light path diagnosticsLight path diagnostics is a system of LEDs on the control panel and on the system board of the computenode. When an error occurs, LEDs are lit throughout the compute node. If the control panel indicates anerror, use the descriptions of the LEDs to diagnose the problem and to take corrective action.Chapter 8. Troubleshooting 485
