适用场景

AFF-A300
ONTAP 9.9.9.1P9
10G集群网络端口
连接节点和交换机集群端口的双轴缆线
运行EFOS 3.8.0.2的BES-53248

问题描述

一个集群网络端口每小时报告大量CRC错误。示例：

...

Thu Jun 23 02:05:22 +0200 [node_name-01: vifmgr: vifmgr.cluscheck.hwerrors:alert]: Port e0a on node node_name-01 is reporting a high number (at least 1 per 1000 packets) of observed hardware errors (CRC, length, alignment, dropped).

Thu Jun 23 02:05:22 +0200 [node_name-01: vifmgr: callhome.clus.net.degraded:alert]: Call home for CLUSTER NETWORK DEGRADED: CRC Errors Detected - High CRC errors detected on port e0a node node_name-01

Thu Jun 23 03:05:23 +0200 [node_name-01: vifmgr: vifmgr.cluscheck.hwerrors:alert]: Port e0a on node node_name-01 is reporting a high number (at least 1 per 1000 packets) of observed hardware errors (CRC, length, alignment, dropped).

指向问题描述源的多个系统运行状况警报。示例：

NodeIfInErrorsWarnAlert

The percentage of inbound packet errors of node "node_name-01" on interface "e0a" is above the warning threshold.

ClusterIfInErrorsWarn_Alert

The percentage of inbound packet errors of switch interface "switch_name-01/Slot: 0 Port: 2 25G - Level" is above the warning threshold.

The percentage of outbound packet errors of switch interface "switch_name-01/Slot: 0 Port: 1 25G - Level" is above the warning threshold.

在一个端口上收到错误并传输到另一个端口：

(switch_name-01)#show interface 0/1 Interface :.................................. 0/1 Packets Received Without Error................. 24203865 Packets Received With Error.................... 0 Broadcast Packets Received..................... 4279 Receive Packets Discarded...................... 375 Packets Transmitted Without Errors............. 24677379 Transmit Packets Discarded..................... 897376 Transmit Packet Errors......................... 897376 ...

(switch_name-01)#show interface 0/2 Interface :.................................. 0/2 Packets Received Without Error................. 15630167 Packets Received With Error.................... 1019693 Broadcast Packets Received..................... 2265 Receive Packets Discarded...................... 13565 Packets Transmitted Without Errors............. 15644072 Transmit Packets Discarded..................... 1156 Transmit Packet Errors......................... 0 ......

问题描述将在以下时间后保留：
- 关闭NetApp节点02上的端口e0a并将其重新激活。
- 关闭BES-53248集群网络交换机上的端口0/1并将其重新激活。
- 已重新拔插两端的缆线。
移动可疑集群LIF的主端口将停止报告的初始错误消息。
switch_name-01端口0/2连接到node_name-02集群端口e0a。
