FIGURE 11-4Diagnostics 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.
