不支持修改"Automatic－切换－onfailure"选项，因为调解器磁盘未正确连接到两个节点

尝试将auto-failure-domain从更 auso-disabled 改为 auso-on-cluster-disaster 错误时、系统会观察到：

示例：

ClusterA::> metrocluster modify -auto-switchover-failure-domain auso-on-cluster-disaster     Error: command failed: Modifying the "automatic-switchover-onfailure" option is not supported, since mediator disks are not connected properly to both the nodes. Use the "mailbox-disk show" command on both nodes to verify that they are able to discover the mediator disks, then try the command again.
