On-Board Failure Logging
The Generation 2 Fibre Channel switching modules provide the facility to log failure data to persistent
storage, which can be retrieved and displayed for analysis. This on-board failure logging (OBFL) feature
stores failure and environmental information in nonvolatile memory on the module. The information will
help in post-mortem analysis of failed cards.
