v Diagnostic programs and error messages Real Time Diagnostics tests the major components of the BladeCenter unit, including the management modules, I/O modules, removable-media drives, and the blade servers, while the operating system is running. Real Time Diagnostics can be plugged into an existing IBM Director environment or installed without IBM Director present. For documentation and download information for Real Time Diagnostics, see http://www.ibm.com/systems/management/. For more information about diagnostic programs and error messages, see the Problem Determination and Service Guide for your blade server. The IBM Dynamic System Analysis (DSA) diagnostic programs are the primary method of testing the major components of the blade server. The diagnostic programs are available in the preboot environment by pressing F2 during the boot process. The Preboot DSA diagnostic programs are stored in integrated USB memory and collect and analyze system information to aid in diagnosing blade server problems. The diagnostic programs collect the following information about the blade server: - System configuration - Network interfaces and settings - Installed hardware - Light path diagnostics status - Vital product data, firmware, and BIOS configuration - Storage drive health - Baseboard Management Controller logs The diagnostic programs create a merged log that includes events from all collected logs. The information is collected into a file that you can send to the IBM Support Center. Additionally, you can view the blade server information locally through a generated text report file. You can also copy the log to removable media and view the log from a Web browser. Note: If you are unable to find the system-error logs in the blade server firmware code, view the system-event log in the BladeCenter management module. v Light path diagnostics Use light path diagnostics LEDs on the system board to diagnose system errors. If the system-error LED on the system LED panel on the front or rear of the BladeCenter unit is lit, one or more error LEDs on the BladeCenter unit components also might be lit. These LEDs help identify the cause of the problem. Blade server error LEDs are described in the Problem Determination and Service Guide for your blade server. 48 BladeCenter HS12 Type 8014 or 8028: Installation and User's Guide
