Diagnostic tools
The section introduces available tools to help you diagnose and solve
hardware-related problems.
v Light path diagnostics
Use light path diagnostics to diagnose system errors quickly. See “Light path
diagnostics” on page 134 for more information.
v 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” on page 146 for more
information.
v 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
– Common Information Model (CIM)
– Web browser
For 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, and
the Integrated Management Module II User's Guide at http://www.ibm.com/
support/entry/portal/docdisplay?lndocid=MIGR-5086346.
v IBM Dynamic System Analysis
Two editions of IBM Dynamic System Analysis (DSA) are available for
diagnosing problems, DSA Portable and DSA Preboot:
– DSA Portable
DSA Portable collects and analyzes system information to aid in diagnosing
server problems. DSA Portable 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
- 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 information
