6 Performing Diagnostics

SANsurfer FC HBA Manager provides end-to-end diagnostics that allow you to test adapters and the devices to which they are connected. Diagnostic tests include the following:

„The external loopback test, which evaluates the ports (transmit and receive transceivers) on the adapter and the error rate.

„10-bit internal or 1-bit serial internal loopback test (available on 8Gb adapters, such as the QLE256x).

„The read/write buffer test verifies the link between the adapter and its attached devices.

This section contains the following diagnostic procedures:

„“Running Loopback and Read/Write Buffer Diagnostic Tests” on page 6-1

„“Viewing Adapter Port Transceiver Details” on page 6-7

Running Loopback and Read/Write Buffer Diagnostic Tests

SANsurfer FC HBA Manager offers two diagnostic tests: loopback and read/write. You can access the diagnostic testing facility from the Diagnostics page or by clicking the Diags button on the toolbar.

Before running a diagnostic test, consider the following:

„Because diagnostic testing interrupts normal adapter operations, you should run these tests when no other activities are required of the adapter.

„The adapter state reverts to pre-test conditions at the end of the testing process.

„Diagnostic tests read and write to sensitive areas on the adapter.

„Disruption of some diagnostic tests may require a complete update of the adapter's critical memory areas.
