A300/FAS8200 ， A200/FAS2600 ， A220/FAS2700 ， C190 上的 e0a/e0b 链路板可能导致接管
状态信息
适用场景

问题描述
- 集群端口 e0a 或 e0b （或两个端口）会同时出现链路挡板或关闭。
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.
- 检查集群端口状态和存储故障转移状态：

Takeover
Node Partner Possible State Description
------------- -------------- -------- -------------------------------------
cluster-01 cluster-02 false Connected to cluster-02, Partial
giveback, Takeover is not possible:
The version of software running on
each node of the SFO pair is
incompatible, NVRAM log not synchronized
cluster-02 cluster-01 - Waiting for cluster applications to
come online on the local node
Offline applications: mgmt, vldb,
vifmgr, bcomd, crs.
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 ）
- 不会发生存储接管，并且两个节点都将超出仲裁。 两个节点都不会提供数据。
