Loopback failures are reported on already failed ports. After initial port hardware failures, such as: %PORT-5-IF_DOWN_HW_FAILURE: %$VSAN 1%$ Interface fc8/48 is down (Hardware Failure) %PORT-5-IF_DOWN_HW_FAILURE: %$VSAN 1%$ Interface fc8/47 is down (Hardware Failure) %PORT-5-IF_DOWN_HW_FAILURE: %$VSAN 1%$ Interface fc8/46 is down (Hardware Failure) %PORT-5-IF_DOWN_HW_FAILURE: %$VSAN 1%$ Interface fc8/45 is down (Hardware Failure) %PORT-5-IF_DOWN_HW_FAILURE: %$VSAN 1%$ Interface fc8/44 is down (Hardware Failure) %PORT-5-IF_DOWN_HW_FAILURE: %$VSAN 1%$ Interface fc8/43 is down (Hardware Failure) %PORT-5-IF_DOWN_HW_FAILURE: %$VSAN 1%$ Interface fc8/42 is down (Hardware Failure) %PORT-5-IF_DOWN_HW_FAILURE: %$VSAN 1%$ Interface fc8/41 is down (Hardware Failure) the diagnostic test continues to run and some time later the following type of syslogs messages are logged: %DIAG_PORT_LB-2-INT_PORT_LOOPBACK_TEST_FAIL: Module:8 Test:Internal PortLoopback failed 10 consecutive times. Faulty module:Module 8 affected ports:41-44 Error:Packets dropped on FCMAC %DIAG_PORT_LB-2-SNAKE_TEST_LOOPBACK_TEST_FAIL: Module:8 Test:SnakeLoopback failed 10 consecutive times. Faulty module: affected ports:41-44 Error:Packets dropped on FCMAC %DIAG_PORT_LB-2-SNAKE_TEST_LOOPBACK_TEST_FAIL: Module:8 Test:SnakeLoopback failed 10 consecutive times. Faulty module: affected ports:1-40,45-48 Error:Test Failed, Could not identify the Faulty Device
This issue only applies to ports that have already failed and been set to 'hardware failure' state.
Replace the failed module.
The %DIAG_PORT_LB-2-SNAKE_TEST_LOOPBACK_TEST_FAIL messages are superflous.
Diagnostic tests are no longer run on already failed ports.
