NETAPP-FAS6220存储集群切换操作手册

单位的中端存储netapp fas6220 由于异常原因，AB两个控制器之间进行了cf cluster切换。当前控制节点运行在FAS6220B节点上。在相关硬件修好后，需要进行集群控制器的切换。

主要过程如下：

1， 登录FAS6220B（当前主控器）串口控制器：root用户 2， 进入高级模式，查看当前状态：

FAS6220-2B(takeover)> priv set advanced

Warning: These advanced commands are potentially dangerous; use them only when directed to do so by NetApp personnel. 查看集群状态：

FAS6220-2B(takeover)*> cf status

FAS6220-2B has taken over FAS6220-2A. FAS6220-2A is ready for giveback. 3， 在集群高级模式下进行切换：

FAS6220-2B(takeover)*> cf giveback

FAS6220-2B(takeover)*> Fri Jun 3 08:51:39 CST [FAS6220-2B:cf.misc.operatorGiveback:info]: Failover monitor: giveback initiated by operator

Fri Jun 3 08:51:39 CST [FAS6220-2B:cf.fm.givebackStarted:notice]: Failover monitor: giveback started.
