CAUTION!

Although SANsurfer FC HBA Manager protects against normal operation interruption and testing disruption, it is your responsibility to ensure that the diagnostics are run without causing interruptions to other processes and disruptions to the actual testing process.

The following sections provide information on these diagnostic tests:

„“Preparing for Diagnostic Testing” on page 6-2

„“Running the Loopback Test” on page 6-6

„“Running the Read/Write Buffer Test” on page 6-6

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” on page 6-2

„“Preparing for the Loopback Test” on page 6-3

„“Preparing for the Read/Write Buffer Test” on page 6-5

Finding the Adapter Port You Want to Test

You can find the location of a port by the way the hardware flashes. SANsurfer FC HBA Manager allows you to activate a flash beacon on a port. This flash beacon can be toggled 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 QLA22xx series or older adapters.
