ML325
-- Debug Techniques for SAN Configurations
Course Description
ML325 is an advanced lab-based
course which provides participants with hands-on experience
debugging Fibre Channel SANs using protocol analyzers.
Course Objective
Provide the student with methods
for debugging error conditions in a Fibre Channel SAN
configuration.
Prerequisites
ML201, ML205 and/or ML100 or
equivalent advanced experience with Fibre Channel architecture.
Intended Audience
The class is intended for students
requiring advanced Fibre Channel debugging and troubleshooting
skills. Appropriate audiences may include but are not limited to:
- Design Engineers
- Field Application Engineers
- Technical Support Engineers
Course Format
The lecture will discuss aspects of
the Fibre Channel architecture and the error scenarios relevant to
SAN environments. Real life SAN configurations will be assembled.
A Finisar GT Jammer™ will be used to induce errors in the serial
data stream and the students will use Finisar GTX Analyzers to
capture and analyze the resulting traces. 90% of class time is
spent debugging errors that are injected into the SAN
configuration.
Course Topics

Procedures include:
- Primitive Sequences and Signals
- Frames, Sequences and Exchanges
- Error Policies
- Alternative Recovery Actions
- Appropriate and Pertinent
Extended Link Services and Switch Directory Services
