Troubleshooting Overview Tasks

This section lists the high-level steps to isolate and troubleshoot problems in the Sun

StorEdge 3900 and 6900 series. It offers a methodical approach and lists the tools and

resources available at each step.

Note – A single problem can cause various errors throughout the SAN. A good

practice is to begin by investigating the devices that have experienced “Loss of

Communication” events in the Storage Automated Diagnostic Environment. These

errors usually indicate more serious problems.

A “Loss of Communication” error on a switch, for example, could cause multiple

ports and HBAs to go offline. Concentrating on the switch and fixing that failure can

help bring the ports and HBAs back online.
