不支持修改"automatic-switchover-onfailure"选项，因为介体磁盘未正确连接到两个节点

当尝试将自动切换失败域从 auso-disabled  更改为 auso-on-cluster-disaster  时，观察到错误：

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.
