4. Isolate the components in the path.
The components in the path are the HBA, the cable, the switch-side GBIC, and the
Sun StorEdge network FC switch itself.
To isolate all components, use a combination of the Storage Automated Diagnostic
Environment and the HBA utility (QLogic SunBlade).
Note –
If no HBA utility is present, or if the utilities do not offer diagnostics, a best
guess effort will have to suffice. Storage Automated Diagnostic Environment cannot
test HBAs on Microsoft Windows 2000 hosts at this time.
