NLB 检测到群集主机之间共享的主机优先级

Microsoft.Windows.NetworkLoadBalancing.6.2.NLB.detected.a.duplicate.host.priority.that.is.shared.between.cluster.hosts (Rule)

Knowledge Base article:

摘要

将网络负载平衡 (NLB) 群集中的主机配置为负载平衡网络流量。通过使用 NLB 管理器设置主机配置，如果未正确配置，NLB 群集可能不会正常运行。

解决方案

确保所有的 NLB 节点具有唯一的主机优先级

如果网络负载平衡 (NLB) 主机的主机优先级与另一台主机的主机优先级相同，或该主机优先级无效，则只有纠正问题后群集才会聚合。主机优先级必须为 1 到 32 之间的数字，该值必须对群集中的所有主机都是唯一的。

确保所有的 NLB 主机都具有唯一的主机优先级：
