验证 MetroCluster 配置是否正常

应检查 MetroCluster 配置的运行状况以验证是否正常运行。

检查每个集群中是否已配置 MetroCluster 且其处于正常模式：metrocluster show

cluster_A::> metrocluster show
Cluster                   Entry Name          State
------------------------- ------------------- -----------
 Local: cluster_A         Configuration state configured
                          Mode                normal
                          AUSO Failure Domain auso-on-cluster-disaster
Remote: cluster_B         Configuration state configured
                          Mode                normal
                          AUSO Failure Domain auso-on-cluster-disaster

检查每个节点上是否已启用镜像：metrocluster node show

cluster_A::> metrocluster node show
DR                           Configuration  DR
Group Cluster Node           State          Mirroring Mode
----- ------- -------------- -------------- --------- --------------------
1     cluster_A
              node_A_1       configured     enabled   normal
      cluster_B
              node_B_1       configured     enabled   normal
2 entries were displayed.

检查 MetroCluster 组件是否正常运行：metrocluster check run

cluster_A::> metrocluster check run

Last Checked On: 10/1/2014 16:03:37

Component           Result
------------------- ---------
nodes               ok
lifs                ok
config-replication  ok
aggregates          ok
4 entries were displayed.

Command completed. Use the "metrocluster check show -instance" command or sub-commands in "metrocluster check" directory for detailed results.
To check if the nodes are ready to do a switchover or switchback operation, run "metrocluster switchover -simulate" or "metrocluster switchback -simulate", respectively.

检查是否不存在任何运行状况警报：system health alert show
模拟切换操作：
1. 从任何节点的提示符处，更改为高级权限级别：set -privilege advanced
  提示是否继续进入高级模式时，需要回答 y，然后将显示高级模式提示符（*>）。
2. 使用 -simulate 参数执行切换操作：metrocluster switchover -simulate
3. 恢复为管理员权限级别：set -privilege admin

对于使用 ONTAP Mediator 服务的 MetroCluster IP 配置，请确认 Mediator 服务已启动并正在运行。

确认 Mediator 磁盘对系统可见：storage failover mailbox-disk show

以下示例显示邮箱磁盘已被识别。

node_A_1::*> storage failover mailbox-disk show                     
                 Mailbox
Node             Owner     Disk    Name        Disk UUID
