适用场景

  • MetroCluster IP
  • FAS8200/FASA300 AFF
  • 互连

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:

                                           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:

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:

 name=wafl qp_id=0 state=DISCONNECTED rhp=0xfffff806190ed800 refcnt=0 last_err=12 sq=0 rq=0 tid=0 cq=0 client p_name=wafl state=WAIT_FOR_CONN rhp=0 refcnt=0 last_err=-12 name=wafl qp_id=0 state=CONNECTING rhp=0xfffff8086ce41800 refcnt=0 last_err=12 sq=0 rq=0 tid=0 cq=0 client p_name=wafl state=WAIT_FOR_CONN rhp=0 refcnt=0 last_err=-12 name=raid qp_id=0 state=CONNECTING rhp=0xfffff8029f887000 refcnt=0 last_err=12 sq=0 rq=0 tid=0 cq=0 client p_name=raid state=WAIT_FOR_CONN rhp=0 refcnt=0 last_err=-12 name=raid qp_id=0 state=DISCONNECTED rhp=0xfffff80287209000 refcnt=0 last_err=12 sq=0 rq=0 tid=0 cq=0 client p_name=raid state=WAIT_FOR_CONN rhp=0 refcnt=0 last_err=-12 name=misc qp_id=0 state=CONNECTING rhp=0xfffff8087fa03000 refcnt=0 last_err=12 sq=0 rq=0 tid=0 cq=0 client p_name=misc state=WAIT_FOR_CONN rhp=0 refcnt=0 last_err=-12 name=misc qp_id=0 state=CONNECTING rhp=0xfffff80844c73800 refcnt=0 last_err=12 sq=0 rq=0 tid=0 cq=0 client 

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。
