 Fibre Channel Troubleshooting & Trace Analysis  
  This workshop provides the student with a product-independent, structured approach to troubleshooting Fibre Channel problems with an emphasis on trace analysis. The workshop consists of a series of lecture topics with companion exercises. The lecture introduces a structured approach to problem solving, helps in understanding different types of problems and how to gather information to help in identifying and resolving problems. The lecture also provides an introduction to using a Fibre Channel analyzer to gather detailed information about a problem and how to analyze captured traces to identify problem behaviors The exercises provide a series of “hands-on” activities that give the student an opportunity to apply the information provided in the lecture. Students will install trace viewer software and use real world traces designed to illustrate different problem categories and provide an opportunity to analyze a number of problems.
