Troubleshooting
Storage Service Processor-side troubleshooting refers to messages, alerts, and errors
that the Storage Automated Diagnostic Environment detects while running on the
Storage Service Processor. You can find these messages by monitoring the following
Sun StorEdge 3900 series and Sun StorEdge 6900 series components:
■ Sun StorEdge network FC switch-8 and switch-16 switches

Combining the host-side messages and errors and the Storage Service Processor-side
messages, alerts, and errors into a meaningful context is essential for proper
troubleshooting.
