状态信息

适用于

  • AFF A300/FAS8200
  • AFF A200/FAS2600 ( FAS2620 , FAS2650 )
  • AFF A220/FAS2700 ( FAS2720 , FAS2750 )
  •  AFF C190
  • ONTAP

问题

  • 集群端口 E0A/E0B 链接信舌或同时关闭。

示例:

 Tue Oct 03 11:08:31 CEST [node1: ixgbe/e0b: snmp.link.down:info]: Interface 2 is down. Tue Oct 03 11:08:31 CEST [node1: ixgbe/e0b: netif.linkDown:info]: Ethernet e0b: Link down, check cable. Tue Oct 03 11:08:31 CEST [node1: ixgbe/e0a: snmp.link.down:info]: Interface 1 is down. Tue Oct 03 11:08:31 CEST [node1: ixgbe/e0a: netif.linkDown:info]: Ethernet e0a: Link down, check cable. Tue Oct 03 11:08:32 CEST [node2: ixgbe/e0b: snmp.link.down:info]: Interface 2 is down. Tue Oct 03 11:08:32 CEST [node2: ixgbe/e0b: netif.linkDown:info]: Ethernet e0b: Link down, check cable. Tue Oct 03 11:08:32 CEST [node2: ixgbe/e0a: snmp.link.down:info]: Interface 1 is down. Tue Oct 03 11:08:32 CEST [node2: ixgbe/e0a: netif.linkDown:info]: Ethernet e0a: Link down, check cable.

                                                 giveback, Takeover is not possible:
                                                  The version of software running on

如果端口没有备份、并且启用了连接、则激活和可用性监视器( CLAM )
  • 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。
如果端口没有备份、并且连接不启用活动和可用性监视器( CLAM )
  • 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。
