适用于

  • AFF A400
  • 双节点无交换机集群
  • 配置集群端口的 X1151A NIC
  • ONTAP 9

问题

  • 由于 CLAM 恐慌而接管的节点：
Panic String: 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.) in SK process mcc_ic_kill_pkt_handler on release 9.12.1P3
  •  受影响节点上集群端口关闭时集群应用程序离线
  • 合作伙伴节点集群端口尽管直接连接但仍处于开启状态
  • Loopback 测试显示两个节点都有开启的端口，但重新连接到合作伙伴时无法链接
  • 受影响节点的电源循环无法解决此问题
