This course presents how to isolate the real cause of a crash in involved crashes. This course features:

• Device Driver data structure tracing and register usage
• Approaches to:
  • Fork level
  • Driver Crashes at:
    • FDT Routines
    • Device IPL
    • Fork IPL
    • I/O Post Processing
    • AST Crashes
    • SMP Crashes
    • Cluster Crashes
• Locating device error information
• Miscellaneous advance crash analysis topics
• Null Frame Procedures effect on stack
• Corrupt stacks
• Identifying system/process hang situations, forced crash and determine missing information at the time of the crash.

Who Should Attend
