- 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。
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。
- 请参见： SU436 ： "Impact ： critical" （影响：严重）状态下的命令执行接管默认配置已更改
- 在EMS日志中可以找到类似的消息：
