Diagnostic tools

The section introduces available tools to help you diagnose and solve hardware-related problems.

  • LCD system information display panel

    Use LCD system information display panel to diagnose system errors quickly.

  • Event logs

    The event logs list the error codes and messages that are generated when an error is detected for the subsystems IMM2, POST, DSA, and the server baseboard management controller. See Event logs for more information.

  • Integrated management module II

    The integrated management module II (IMM2) combines service processor functions, video controller, and remote presence and blue-screen capture features in a single chip. The IMM provides advanced service-processor control, monitoring, and alerting function. If an environmental condition exceeds a threshold or if a system component fails, the IMM lights LEDs to help you diagnose the problem, records the error in the IMM event log, and alerts you to the problem. Optionally, the IMM also provides a virtual presence capability for remote server management capabilities. The IMM provides remote server management through the following industry-standard interfaces:

    • Intelligent Platform Management Protocol (IPMI) version 2.0
    • Simple Network Management Protocol (SNMP) version 3; SNMP Trap version 1.0
    • Common Information Model (CIM)
    • Web browser

    For more information about the integrated management module II (IMM2), see Using the integrated management module, Integrated management module II (IMM2) error messages, and the Integrated Management Module II User's Guide at the Integrated Management Module II User’s Guide .

  • Dynamic System Analysis

    DSA Preboot and LXCE OneCLI are available for diagnosing problems:

    • LXCE OneCLI

      LXCE OneCLI collects and analyzes system information to aid in diagnosing server problems. LXCE OneCLI runs on the server operating system and collects the following information about the server:

      • Drive health information
      • Event logs for ServeRAID controllers and service processors
      • IMM configuration information
      • IMM environmental information
      • Option card driver and firmware 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
      • RAID controller configuration
      • Service processor (integrated management module) status and configuration
      • System configuration
      • Vital product data, firmware, and UEFI configuration
      LXCE OneCLI creates an inventory report, which is a chronologically ordered merge of the system-event log (as the IPMI event log), the integrated management module (IMM) event log (as the ASM event log), and the operating-system event logs. You can send the inventory report as a file to Lenovo Support (when requested by Lenovo Support) or view the information as a text file or HTML file.
      Note
      Use the latest available version of LXCE OneCLI to make sure you are using the most recent configuration data. For documentation and download information for LXCE OneCLI, see the Lenovo Systems Management Solutions website.
    • DSA Preboot

      DSA Preboot diagnostic program is stored in the integrated USB memory on the server. DSA Preboot collects and analyzes system information to aid in diagnosing server problems, as well as offering a rich set of diagnostic tests of the major components of the server. DSA Preboot collects the following information about the server:

      • Drive health information
      • IMM2 configuration information
      • IMM2 environmental information
      • Event logs for ServeRAID controllers and service processors
      • Installed hardware, including PCI and USB information
      • LCD system information display panel status
      • Microprocessor, input/output hub, and UEFI error logs
      • Network interfaces and settings
      • Option card driver and firmware information
      • RAID controller configuration
      • Service processor (integrated management module) status and configuration
      • System configuration
      • Vital product data, firmware, and UEFI configuration

      DSA Preboot also provides diagnostics for the following system components (when they are installed):

      1. Emulex network adapter
      2. IMM I2C bus
      3. LCD system information display panel
      4. Memory modules
      5. Microprocessors
      6. Optical devices (CD or DVD)
      7. SAS or SATA drives
      8. LSI Controller
      9. Broadcom network adapter
      10. FusionIO storage
      11. Intel GPU
      12. Nvidia GPU

      See Running the DSA Preboot diagnostic programs for more information on running the DSA Preboot program on the server.
