FIGURE 11-4 Diagnostics Using QLogic SunBlade
In this example, the HBA-to-switch cable was removed temporarily and a loopback
connector was inserted into the HBA. The Qlogc SANblade LoopBack diagnostics
were then run. The HBA passed the tests.
Note – The next components that can be isolated are the switch-side GBIC and the
Sun StorEdge network FC switch itself.
For these components, you can launch the tests using the Storage Automated
Diagnostic Environment Diagnose -> Tests -> Test From Topology functionality.
5. Again, temporarily remove the cable from the switch port in question, insert a
loopback connector plug and run the switch port diagnostics.
The first run will test the switch-side GBIC as well as the Sun StorEdge network FC
switch.
