Switch Troubleshooting
This appendix provides basic guidelines that you can use to isolate problems found
in a configuration using Brocade Communications Systems, Inc. Silkworm switches.
It assumes you have been trained on all the components, such as storage and
switches, that make up the configuration.
The scope of this appendix is to highlight the differences of troubleshooting with a
Brocade Silkworm configuration to that of a configuration that contains the current
Sun StorEdge Network Fibre Channel family of switches. Current support is limited
to diagnosing failures down to the FRU level. In Sun’s support model, the entire
Silkworm switch is considered a FRU. Many of Brocade’s internal diagnostics and
messages, while useful for depot or Root Cause Analysis situations, are not
ultimately relevant to a Sun Service Engineer trying to isolate to a FRU.
