问题描述

EMS 错误：

Wed Dec 21 07:50:26 +0900 [Node-02: intr: netif.linkErrors:error]: Excessive link errors on network interface e0a. Might indicate a bad cable, switch port, or NIC, or that a cable connector is not fully inserted in a socket. On a 10/100 port, might indicate a duplex mismatch.

运行状况警报：

Node: node_name

Resource: Ethernet1/29/1

Severity: Major

Indication Time: Mon Jan 04 16:15:33 2021

Suppress: false

Acknowledge: false

Probable Cause: The percentage of inbound packet errors of switch interface

"switch_name(XXXXXXXXXXX)/Ethernet1/29/1" is above the warning threshold.

Possible Effect: Communication between nodes in the cluster might be degraded.

Corrective Actions: 1) Migrate any cluster LIF that uses this connection to another port connected to a cluster switch.            For example, if cluster LIF "clus1" is on port e0a and the other LIF is on e0b, run the following             command to move "clus1" to e0b: "network interface migrate -vserver vs1 -lif clus1 -sourcenode node1           -destnode node1 -dest-port e0b"

2) Replace the network cable with a known-good cable.

If errors are corrected, stop. No further action is required. Otherwise, continue to Step 3.

           3) Move the network cable to another port on the node (if available). Migrate the cluster LIF to             the new port.

If errors are corrected, contact technical support to troubleshoot the original node port.

Otherwise, continue to Step 4.

4) Move the network cable to another available cluster switch port.

Migrate the cluster LIF back to the original port.

If errors are corrected, contact technical support to troubleshoot the original switch port.

If errors persist, contact technical support for further assistance.
