Verifying the A2 or B2 FC Link
You can check the A2 or B2 FC link using the Storage Automated Diagnostic
Environment, Diagnose—Test from Topology functionality. The Storage Automated
Diagnostic Environment’s implementation of diagnostic tests verifies the operation
of user-selected components. Using the Topology view, you can select specific tests,
subtests, and test options.

1. Quiesce the I/O on the A2 or B2 FC link path.
2. Break the connection by uncabling the link.
3. Insert the loopback connector in to the switch port.
4. Run switchtest :
a. If the test fails, replace the GBIC and rerun switchtest .
b. If the test fails again, replace the switch.
