问题描述

丢失并恢复MetroCluster IP连接后、即使物理连接正常且运行正常、HA、DR或AUX互连连接也可能会断开。

即使iWARP连接在中启动、镜像状态也会报告为已禁用和脱机 metrocluster interconnect show:

Cluster1::> metrocluster interconnect show (metrocluster interconnect show) Mirror Mirror Partner Admin Oper Node Partner Name Type Status Status Adapter Type Status ---- ------------ ------- -------- ------- ------- ------ ------ Node1A Node2A HA enabled online e1a iWARP Up e1b iWARP Up Node1B DR disabled offline e1a iWARP Up e1b iWARP Up Node2B AUX disabled offline e1a iWARP Up e1b iWARP Up Node2A Node1A HA enabled online e1a iWARP Up e1b iWARP Up Node2B DR disabled offline e1a iWARP Up e1b iWARP Up Node1B AUX disabled offline e1a iWARP Up e1b iWARP Up

本地HA也可能会因NVRAM同步丢失而脱机。可以在中查看故障转移资格 storage failover show:

Cluster1::> storage failover show Takeover Node Partner Possible State Description -------------- -------------- -------- ------------------------------------- Node1 node2 false Connected to node2, Takeover is not possible: NVRAM log not synchronized Node2 Node1 false Connected to node1, Takeover is not possible: NVRAM log not synchronized

如果AutoSupport可用、请检查 METROCLUSTER-TCP-SYSCTL-MCC 完整AutoSupport中的部分并查找以下错误：

如果 WAIT_FOR_CONN rhp=0 refcnt=0 last_err=-12 存在错误，则问题描述将被确认为错误 1307431。
