press F1, the Lenovo XClarity Provisioning Manager V3 interface is displayed by default. You can
perform hard drive diagnostics from this interface. From the Diagnostic page, click Run Diagnostic ➙
Disk Drive Test.
Based on those tests:
• If the adapter passes the test but the drives are not recognized, replace the backplane signal cable
and run the tests again.
• Replace the backplane.
• If the adapter fails the test, disconnect the backplane signal cable from the adapter and run the tests
again.
• If the adapter fails the test, replace the adapter.
