适用场景

AFF A300、FAS8200
AFF A200、FAS2650、FAS2620
AFF A220、AFF C190、FAS2750、FAS2720
采用无交换机配置的双节点集群
启用连接、流畅度和可用性监控器(VANM)的原因是：
- ONTAP 9.8或更高版本
- 或配置有SAN实体的集群

问题描述

两个节点上的集群网络端口e0a和e0b几乎同时关闭：

其中一个节点发生"仲裁不足"崩溃。

PANIC : Received PANIC packet from partner, receiving message is (Coredump and takeover initiated because Connectivity, Liveliness and Availability Monitor (CLAM) has determined this node is out of quorum.
