Link Test |

The linktest test is delivered with the Storage Automated Diagnostic Environment software. This test verifies the functionality for passive FC components in a SAN or DAS environment. The test will provide failing FRU isolation for devices which have external loopback tests. The test will test both ends of the link segment (if possible) and enter a guided isolation tool when a failure is detected.
linktest is executed from the view "Diagnose->Test->Test from Topology" or "Monitor->Monitor Topology-> (Select a topology)" by right clicking on a link segment's icon. Typically linktest is run when the user detects a bad or intermittent link via an "alert" or by the visual detection on the topology graph (a red link).
After starting linktest, the "Test Manager" will be utilized to guide the user through FRU isolation.
