验证修复和手动切回
可以通过在协商切换后将集群切回原始数据中心来测试修复和手动切回操作，从而验证数据可用性是否受到影响（SMB 除外）。
此测试应该需要大约 30 分钟。
此过程的预期结果是应将服务切回其主节点。
- 验证是否已完成修复：metrocluster node show 以下示例显示已成功完成命令：
cluster_A::> metrocluster node show
DR Configuration DR
Group Cluster Node State Mirroring Mode
----- ------- ------------------ -------------- --------- --------------------
1 cluster_A
node_A_1 configured enabled heal roots completed
cluster_B
node_B_2 unreachable - switched over
42 entries were displayed.metrocluster operation show - 验证是否已镜像所有聚合：storage aggregate show 以下示例显示所有聚合的 RAID 状态均为 mirrored：
cluster_A::> storage aggregate show
cluster Aggregates:
