Running Loopback Tests

To run a loopback test, use the "Loopback Test" section of the Advanced Diagnostics dialog box. You can run the following loopback test combinations using the appropriate check boxes:

PCI Loopback Test - A firmware controlled diagnostic test in which a random data pattern is routed through the PCI bus without being sent to an adapter link port. The returned data is subsequently validated for integrity.

Internal Loopback Test - A diagnostic test in which a random data pattern is sent down to an adapter link port, then is immediately returned without actually going out on the port. The returned data is subsequently validated for integrity.

External Loopback Test - A diagnostic test in which a random data pattern is sent down to an adapter link port. The data goes out the port and immediately returns via a loopback connector. The returned data is subsequently validated for integrity.

Note: You cannot run the External Loopback test and ECHO test concurrently. If you select External Loopback the ECHO test section is disabled and vice versa.

You can specify the number of test cycles by clicking one of the cycle counts values in the "Test Cycles" section of the dialog box or enter a custom cycle count if you wish. The Test Status section displays how many cycles of each test ran. The "Error Action" section of the dialog box enables you to define what should be done in the event of a test failure.

There are two error action options:

Stop Test - The error will be logged and the test aborted. No further tests will run.

Ignore - Log the error and proceed with the next test cycle.

To run loopback tests:

1.Start the HBAnyware utility.

2.From the discovery-tree, select the HBA on which you wish to run the Loopback Test.

3.Select the Diagnostics tab and click Advanced Diagnostics Tests. From the "Loopback Test" section of the dialog box, choose the type of Loopback test you wish to run and define the loopback test parameters.

Note: You must insert a loopback plug in the selected HBA before running an

External Loopback test.

4. Click Start. The following warning appears:
