Preparing for Diagnostic Testing

Preparation differs for the loopback and read/write buffer tests. In addition, you
can use the SANsurfer FC HBA Manager to locate the adapter you want to test.
NOTE:
The loopback test is disabled on all Linux inbox drivers.
The following sections provide information about how to prepare for diagnostic
testing:

Finding the Adapter Port You Want to Test

Most adapter ports provide a beacon LED that lets you find the location of a port
by the way it flashes. SANsurfer FC HBA Manager allows you to activate a flash
beacon on a port. You can toggle this flash beacon on and off. Flash the 2xxx
adapter port's LED to locate the adapter port in your computer.
NOTE:
This feature is not supported on Converged Network Adapters or QLA22xx
series or older Fibre Channel adapters.
