在无交换机集群系统中、只有一个节点的端口显示为已降级
适用场景
- ONTAP 9
- 双节点无交换机集群(TNSC)
问题描述
- AutoSupport警报
HA Group Notification (CLUSTER NETWORK DEGRADED) ALERT
EMS log显示其中一个集群端口处于degraded状态。
[vifmgr.reach.skipped:notice]: Network port e0d on node Node-01 was not scanned for reachability because it was administratively or operationally down at the time of the scan.
[vifmgr.port.monitor.failed:error]: The "link_flapping" health check for port e0d (node node-01) has failed. The port is operating in a degraded state.
[vifmgr.portDeg.lifMoved:notice]: LIF node-01_clus2 (on virtual server ****), IP address *****, is being moved to node node-01, port e0c from node node-01,
port e0d because the port's health status is in a degraded state.
network port show命令输出指示只有一个节点的端口处于degraded状态。
配对节点的两个集群端口均处于healthy状态。

- 重置直接连接电缆不会改善这种情况。
