适用场景

  • FAS2552
  • FAS2554
  • ONTAP 8.3.2P5

问题描述

  • 集群端口e0e/e0f会同时关闭或关闭链路。

示例:

[ltm_services: snmp.link.down:info]: Interface 3 is down.
[ltm_services: netif.linkDown:info]: Ethernet e0e: Link down, check cable.
[pmcsas_timeout_0: sas.adapter.debug:info]: params: {'debug_string': 'Link down too long ... offlining', 'adapterName': '0b'}
[ltm_services: snmp.link.down:info]: Interface 4 is down.
[ltm_services: netif.linkDown:info]: Ethernet e0f: Link down, check cable.

 

如果端口未恢复、并且已启用连接、则显示实时性和可用性监控(CLAL)。

  • 其中一个节点上将出现“超出法定人数”紧急情况。
示例:
 
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.
 
  • 将接管出现紧急情况的节点、正常运行的节点将为所有数据提供服务。
如果端口未恢复、并且未启用连接、则显示实时性和可用性监控(CLAL)。
  • 将不会进行接管操作、并且两个节点都将超出法定数量。两个节点都不会提供数据。
