Title
Abnormal Network Errors Detected on Network Interface Controller Embedded (LOM) Port 1. -
Description
Alerts reported:Index Time Alert Message1 2019-07-05 13:56:25 Abnormal network errors detected on Network Interface Controller Embedded (LOM) Port 1. The errors could be caused by network congestion or packet errors. Recovery actions: First, check your network. If that does not resolve the problem, then replace the NIC card. If the NIC is embedded, the storage appliance requires service.Events:CRITICAL 2019-07-05 13:56:25 NIC controller Embedded (LOM) Port 1 packet error rate reaches critical threshold.Replication could be affected -
Resolution
Recommendation: Replace the NICSupporting Evidence:Alerts reported:Index Time Alert Message1 2019-07-05 13:56:25 Abnormal network errors detected on Network Interface Controller Embedded (LOM) Port 1.

Let the system run for 24 to 48 hours to determine this.Significant errors report eth0 and eth1 even after the cable switchFrom sys.configeth0 Link encap:Ethernet HWaddr 00:0A:F7:14:B7:90UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1RX packets:28499681269 errors:106587908 dropped:104592935 overruns:68 frame:106587840TX packets:24374396252 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:1000RX bytes:41560046090193 (37.7 TiB) TX bytes:31980558033231 (29.0 TiB)Interrupt:186 Memory:d1000000-d17fffffeth1 Link encap:Ethernet HWaddr 00:0A:F7:14:B7:90UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1RX packets:79122977800 errors:5264897 dropped:5136849 overruns:662 frame:5264235TX packets:26171287762 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:1000RX bytes:117835402138274 (107.1 TiB) TX bytes:34672265613713 (31.5 TiB)Interrupt:83 Memory:d2000000-d27fffffFinal Analysis:Swapping the Cable from eth0 to eth1 narrowed down more than just a new cable, it can rule out switch port/path/cable....IE everything but the card. Since the errors are stil reporting what is left is the NIC looks to be bad and need replacement.
