Running Loopback Tests
To run a loopback test, use the Loopback Test section of the Advanced Diagnostics dialog box.
Loopback Test Combinations
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.
Error Action
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.
Test Cycles
Enables you to specify test cycles three ways:
• Select an established cycle count by clicking on the corresponding radio button.
• Enter a custom cycle count in the blank field in the Test Cycles area.
• Set the test to run until you manually click Stop, by selecting the Infinite radio button.
Test Pattern
Enter a custom test pattern to be used in tests that transfer data. The test pattern can be up to 8
hexadecimal bytes.
Test Status
The Test Status section displays how many completed cycles of each test ran, as well as the number of
errors.
Procedure
To run loopback tests:
1. From the discovery-tree, select the HBA on which you wish to run the Loopback Test.
2. 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 cannot run the External Loopback test and ECHO test concurrently. If you select
External Loopback the ECHO test section is disabled and vice versa.
Note: You must insert a loopback plug in the selected HBA before running an
External Loopback test.
