After an initial implementation of a SC Fibre Channel front-end, during the failover test one of the controllers gets reset. All Virtual WWNs from the reset controller are migrated to a single port of the remaining controller.

C. This is the expected behavior and the test completed successfully
D. FC zoning is not enabled, enable zone config
