Diagnostic toolsThe section introduces available tools to help you diagnose and solvehardware-related problems.v Light path diagnosticsUse light path diagnostics to diagnose system errors quickly. See “Light pathdiagnostics” on page 134 for more information.v Event logsThe event logs list the error codes and messages that are generated when anerror is detected for the subsystems IMM2, POST, DSA, and the serverbaseboard management controller. See “Event logs” on page 146 for moreinformation.v Integrated management module IIThe integrated management module II (IMM2) combines service processorfunctions, video controller, and remote presence and blue-screen capture featuresin a single chip. The IMM provides advanced service-processor control,monitoring, and alerting function. If an environmental condition exceeds athreshold or if a system component fails, the IMM lights LEDs to help youdiagnose the problem, records the error in the IMM event log, and alerts you tothe problem. Optionally, the IMM also provides a virtual presence capability forremote server management capabilities. The IMM provides remote servermanagement through the following industry-standard interfaces:– Intelligent Platform Management Protocol (IPMI) version 2.0– Simple Network Management Protocol (SNMP) version 3– Common Information Model (CIM)– Web browserFor more information about the integrated management module II (IMM2), see“Using the integrated management module” on page 114, Appendix A,“Integrated management module II (IMM2) error messages,” on page 335, andthe Integrated Management Module II User's Guide at www.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5089484&brandind=5000008.v IBM Dynamic System AnalysisTwo editions of IBM Dynamic System Analysis (DSA) are available fordiagnosing problems, DSA Portable and DSA Preboot:– DSA PortableDSA Portable collects and analyzes system information to aid in diagnosingserver problems. DSA Portable runs on the server operating system andcollects the following information about the server:- Drive health information- Event logs for ServeRAID controllers and service processors- IMM2 configuration information- IMM2 environmental information- Installed hardware, including PCI and USB information- Installed applications and hot fixes- Kernel modules- Light path diagnostics status- Microprocessor, input/out hub, and UEFI error logs- Network interfaces and settings- Option card driver and firmware information132 IBM System x3550 M4 Type 7914: Installation and Service Guide
