适用场景

  • FAS 系统
  • AFF 系统
  • 双节点无交换机集群

问题描述

  • 集群端口在双节点无交换机集群中彼此相连,如以下示例所示:
    • node-1 e0a <-> node-2 e0a
    • node-1 e0b <-> node-2 e0b
  • 在这种情况下,如果一个节点上的一个集群端口发生故障,则这两个节点上的集群互连链路会同时发生故障。

例如:

Tue Jul 27 02:24:18 IST [Node-1: kernel: netif.linkDown:info]: Ethernet e0a: Link down, check cable.
Tue Jul 27 02:24:21 IST [Node-1: vifmgr: vifmgr.portdown:notice]: A link down event was received on node Node-1, port e0a.
Tue Jul 27 02:24:24 IST [Node-1: vifmgr: vifmgr.clus.linkdown:EMERGENCY]: The cluster port e0a on node Node-1 has gone down unexpectedly
                   
Tue Jul 27 02:24:18 IST [Node-2: kernel: netif.linkDown:info]: Ethernet e0a: Link down, check cable.
Tue Jul 27 02:24:21 IST [Node-2: vifmgr: vifmgr.portdown:notice]: A link down event was received on node Node-2, port e0a.
Tue Jul 27 02:24:25 IST [Node-2: vifmgr: vifmgr.clus.linkdown:EMERGENCY]: The cluster port e0a on node Node-2 has gone down unexpectedly.

  • 在已关闭的集群端口上托管的集群 LIF 将移至两个节点上的冗余集群端口。

例如:

Tue Jul 27 02:24:24 IST [Node-1: vifmgr: vifmgr.lifsuccessfullymoved:notice]: LIF Node-1_clus1 (on virtual server 5432198765), IP address 169.X.X.X, is now hosted on node Node-1, port e0b.
Tue Jul 27 02:24:25 IST [Node-2: vifmgr: vifmgr.lifsuccessfullymoved:notice]: LIF Node-2_clus1 (on virtual server 5432198765), IP address 169.X.X.X, is now hosted on node Node-2, port e0b.
